Whenever the projection code +* (pcode) or any of ref[4] are set or changed then this flag must be +* set to zero to signal the initialization routine, celset(), to +* redetermine the function pointers and recompute intermediaries. +* Once this has been done pcode itself is ignored. +* +* double ref[4] +* The first pair of values should be set to the celestial longitude +* and latitude (usually right ascension and declination) of the +* reference point of the projection. These are given by the CRVALn +* keywords in FITS. +* +* The second pair of values are the native longitude of the celestial +* pole and the celestial latitude of the native pole and correspond to +* FITS keywords LONPOLE and LATPOLE. +* +* LONPOLE defaults to 0 degrees if the celestial latitude of the +* reference point of the projection is greater than the native +* latitude, otherwise 180 degrees. (This is the condition for the +* celestial latitude to increase in the same direction as the native +* latitude at the reference point.) ref[2] may be set to 999.0 to +* indicate that the correct default should be substituted. +* +* In some circumstances the celestial latitude of the native pole may +* be determined by the first three values only to within a sign and +* LATPOLE is used to choose between the two solutions. LATPOLE is +* set in ref[3] and the solution closest to this value is used to +* reset ref[3]. It is therefore legitimate, for example, to set +* ref[3] to 999.0 to choose the more northerly solution - the default +* if the LATPOLE card is omitted from the FITS header.

Box 76, +* Epping, NSW, 2121, +* AUSTRALIA +* +*============================================================================= +* +* C routines which implement the FITS World Coordinate System (WCS) +* convention. +* +* Summary of routines +* ------------------- +* These utility routines apply the linear transformation defined by the WCS +* FITS header cards. There are separate routines for the image-to-pixel, +* linfwd(), and pixel-to-image, linrev(), transformations. +* +* An initialization routine, linset(), computes intermediate values from +* the transformation parameters but need not be called explicitly - see the +* explanation of lin.flag below. +* +* An auxiliary matrix inversion routine, matinv(), is included. It uses +* LU-triangular factorization with scaled partial pivoting. +* +* +* Initialization routine; linset() +* -------------------------------- +* Initializes members of a linprm data structure which hold intermediate +* values. Note that this routine need not be called directly; it will be +* invoked by linfwd() and linrev() if the "flag" structure member is +* anything other than a predefined magic value. +* +* Given and/or returned: +* lin linprm* Linear transformation parameters (see below). +* +* Function return value: +* int Error status +* 0: Success. +* 1: Memory allocation error. +* 2: PC matrix is singular. +* +* Forward transformation; linfwd() +* -------------------------------- +* Compute pixel coordinates from image coordinates. Note that where +* celestial coordinate systems are concerned the image coordinates +* correspond to (x,y) in the plane of projection, not celestial (lng,lat). +* +* Given: +* imgcrd const double[] +* Image (world) coordinate. +* +* Given and returned: +* lin linprm* Linear transformation parameters (see below). +* +* Returned: +* pixcrd d[] Pixel coordinate. +* +* Function return value: +* int Error status +* 0: Success. +* 1: The transformation is not invertible. +* +* Reverse transformation; linrev() +* -------------------------------- +* Compute image coordinates from pixel coordinates. Note that where +* celestial coordinate systems are concerned the image coordinates +* correspond to (x,y) in the plane of projection, not celestial (lng,lat). +* +* Given: +* pixcrd const double[] +* Pixel coordinate. +* +* Given and/or returned: +* lin linprm* Linear transformation parameters (see below). +* +* Returned: +* imgcrd d[] Image (world) coordinate. +* +* Function return value: +* int Error status +* 0: Success. +* 1: Error. +* +* Linear transformation parameters +* -------------------------------- +* The linprm struct consists of the following: +* +* int flag +* This flag must be set to zero whenever any of the following members +* are set or modified. This signals the initialization routine, +* linset(), to recompute intermediaries. +* int naxis +* Number of image axes. +* double *crpix +* Pointer to the first element of an array of double containing the +* coordinate reference pixel, CRPIXn. +* double *pc +* Pointer to the first element of the PC (pixel coordinate) +* transformation matrix. The expected order is +* +* lin.pc = {PC1_1, PC1_2, PC2_1, PC2_2}; +* +* This may be conveniently constructed from a two-dimensional array +* via +* +* double m[2][2] = {{PC1_1, PC1_2}, +* {PC2_1, PC2_2}}; +* +* which is equivalent to, +* +* double m[2][2]; +* m[0][0] = PC1_1; +* m[0][1] = PC1_2; +* m[1][0] = PC2_1; +* m[1][1] = PC2_2; +* +* for which the storage order is +* +* PC1_1, PC1_2, PC2_1, PC2_2 +* +* so it would be legitimate to set lin.pc = *m. +* double *cdelt +* Pointer to the first element of an array of double containing the +* coordinate increments, CDELTn. +* +* The remaining members of the linprm struct are maintained by the +* initialization routine and should not be modified. +* +* double *piximg +* Pointer to the first element of the matrix containing the product +* of the CDELTn diagonal matrix and the PC matrix. +* double *imgpix +* Pointer to the first element of the inverse of the piximg matrix. +* +* linset allocates storage for the above arrays using malloc(). Note, +* however, that these routines do not free this storage so if a linprm +* variable has itself been malloc'd then these structure members must be +* explicitly freed before the linprm variable is free'd otherwise a memory +* leak will result. +* +* Author: Mark Calabretta, Australia Telescope National Facility +* $Id: lin.c,v 2.8 2002/01/30 06:04:03 mcalabre Exp $ +*===========================================================================*/ + +#include +#include +#include "wcslib.h" + +/* Map error number to error message for each function. */ +const char *linset_errmsg[] = { + 0, + "Memory allocation error", + "PC matrix is singular"};

All the code is +thread safe. The data format used by the zlib library is described by RFCs +(Request for Comments) 1950 to 1952 in the files +http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format) +and rfc1952.txt (gzip format). + +All functions of the compression library are documented in the file zlib.h +(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example +of the library is given in the file example.c which also tests that the library +is working correctly. Another example is given in the file minigzip.c. The +compression library itself is composed of all source files except example.c and +minigzip.c. + +To compile all files and run the test program, follow the instructions given at +the top of Makefile.in. In short "./configure; make test", and if that goes +well, "make install" should work for most flavors of Unix. For Windows, use one +of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use +make_vms.com. + +Questions about zlib should be sent to , or to Gilles Vollant + for the Windows DLL version. The zlib home page is +http://zlib.net/ .

being able to identify portions + * of the input text which are identical to earlier input (within a + * sliding window trailing behind the input currently being processed). + * + * The most straightforward technique turns out to be the fastest for + * most input files: try all possible matches and select the longest. + * The key feature of this algorithm is that insertions into the string + * dictionary are very simple and thus fast, and deletions are avoided + * completely. Insertions are performed at each input character, whereas + * string matches are performed only when the previous match ends. So it + * is preferable to spend more time in matches to allow very fast string + * insertions and avoid deletions. The matching algorithm for small + * strings is inspired from that of Rabin & Karp. A brute force approach + * is used to find longer strings when a small match has been found. + * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze + * (by Leonid Broukhis). + * A previous version of this file used a more sophisticated algorithm + * (by Fiala and Greene) which is guaranteed to run in linear amortized + * time, but has a larger average cost, uses more memory and is patented. + * However the F&G algorithm may be faster for some highly redundant + * files if the parameter max_chain_length (described below) is too large. + * + * ACKNOWLEDGEMENTS + * + * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and + * I found it in 'freeze' written by Leonid Broukhis. + * Thanks to many people for bug reports and testing. + * + * REFERENCES + * + * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". + * Available in http://www.ietf.org/rfc/rfc1951.txt + * + * A description of the Rabin and Karp algorithm is given in the book + * "Algorithms" by R.

style over the previous zlib inflate code + * + * 1.2.beta1 25 Nov 2002 + * - Use pointers for available input and output checking in inffast.c + * - Remove input and output counters in inffast.c + * - Change inffast.c entry and loop from avail_in >= 7 to >= 6 + * - Remove unnecessary second byte pull from length extra in inffast.c + * - Unroll direct copy to three copies per loop in inffast.c + * + * 1.2.beta2 4 Dec 2002 + * - Change external routine names to reduce potential conflicts + * - Correct filename to inffixed.h for fixed tables in inflate.c + * - Make hbuf[] unsigned char to match parameter type in inflate.c + * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset) + * to avoid negation problem on Alphas (64 bit) in inflate.c + * + * 1.2.beta3 22 Dec 2002 + * - Add comments on state->bits assertion in inffast.c + * - Add comments on op field in inftrees.h + * - Fix bug in reuse of allocated window after inflateReset() + * - Remove bit fields--back to byte structure for speed + * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths + * - Change post-increments to pre-increments in inflate_fast(), PPC biased? + * - Add compile time option, POSTINC, to use post-increments instead (Intel?) + * - Make MATCH copy in inflate() much faster for when inflate_fast() not used + * - Use local copies of stream next and avail values, as well as local bit + * buffer and bit count in inflate()--for speed when inflate_fast() not used + * + * 1.2.beta4 1 Jan 2003 + * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings + * - Move a comment on output buffer sizes from inffast.c to inflate.c + * - Add comments in inffast.c to introduce the inflate_fast() routine + * - Rearrange window copies in

The state machine is + structured roughly as follows: + + for (;;) switch (state) { + ... + case STATEn: + if (not enough input data or output space to make progress) + return; + ... make progress ... + state = STATEm; + break; + ... + } + + so when inflate() is called again, the same case is attempted again, and + if the appropriate resources are provided, the machine proceeds to the + next state. The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available.

(In + particular avail_in is zero after the call if enough output space has been + provided before the call.) Flushing may degrade compression for some + compression algorithms and so it should be used only when necessary. This + completes the current deflate block and follows it with an empty stored block + that is three bits plus filler bits to the next byte, followed by four bytes + (00 00 ff ff). + + If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the + output buffer, but the output is not aligned to a byte boundary. All of the + input data so far will be available to the decompressor, as for Z_SYNC_FLUSH. + This completes the current deflate block and follows it with an empty fixed + codes block that is 10 bits long. This assures that enough bytes are output + in order for the decompressor to finish the block before the empty fixed code + block. + + If flush is set to Z_BLOCK, a deflate block is completed and emitted, as + for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to + seven bits of the current block are held to be written as the next byte after + the next deflate block is completed. In this case, the decompressor may not + be provided enough bits at this point in order to complete decompression of + the data provided so far to the compressor. It may need to wait for the next + block to be emitted. This is for advanced applications that need to control + the emission of deflate blocks. + + If flush is set to Z_FULL_FLUSH, all output is flushed as with + Z_SYNC_FLUSH, and the compression state is reset so that decompression can + restart from this point if previous compressed data has been damaged or if + random access is desired.

When decoding + the zlib or gzip format, this will cause inflate() to return immediately + after the header and before the first block. When doing a raw inflate, + inflate() will go ahead and process the first block, and will return when it + gets to the end of that block, or when it runs out of data. + + The Z_BLOCK option assists in appending to or combining deflate streams. + Also to assist in this, on return inflate() will set strm->data_type to the + number of unused bits in the last byte taken from strm->next_in, plus 64 if + inflate() is currently decoding the last block in the deflate stream, plus + 128 if inflate() returned immediately after decoding an end-of-block code or + decoding the complete header up to just before the first byte of the deflate + stream. The end-of-block will not be indicated until all of the uncompressed + data from that block has been written to strm->next_out. The number of + unused bits may in general be greater than seven, except when bit 7 of + data_type is set, in which case the number of unused bits will be less than + eight. data_type is set as noted here every time inflate() returns for all + flush options, and so can be used to determine the amount of currently + consumed input in bits. + + The Z_TREES option behaves as Z_BLOCK does, but it also returns when the + end of each deflate block header is reached, before any actual data in that + block is decoded. This allows the caller to determine the length of the + deflate block header for later use in random access within a deflate block. + 256 is added to the value of strm->data_type when inflate() returns + immediately after reaching the end of the deflate block header. + + inflate() should normally be called until it returns Z_STREAM_END or an + error. However if all decompression is to be performed in a single step (a + single call of inflate), the parameter flush should be set to Z_FINISH. In + this case all pending input is processed and all pending output is flushed; + avail_out must be large enough to hold all the uncompressed data. (The size + of the uncompressed data may have been saved by the compressor for this + purpose.) The next operation on this stream must be inflateEnd to deallocate + the decompression state. The use of Z_FINISH is never required, but can be + used to inform inflate that a faster approach may be used for the single + inflate() call. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call. So the only effect of the flush parameter in this implementation + is on the return value of inflate(), as noted below, or when it returns early + because Z_BLOCK or Z_TREES is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the adler32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the adler32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed adler32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() can decompress and check either zlib-wrapped or gzip-wrapped + deflate data. The header type is detected automatically, if requested when + initializing with inflateInit2(). Any information contained in the gzip + header is not retained, so applications that need that information should + instead use raw inflate, see inflateInit2() below, or inflateBack() and + perform their own processing of the gzip header and trailer. + + inflate() returns Z_OK if some progress has been made (more input processed + or more output produced), Z_STREAM_END if the end of the compressed data has + been reached and all uncompressed output has been produced, Z_NEED_DICT if a + preset dictionary is needed at this point, Z_DATA_ERROR if the input data was + corrupted (input stream not conforming to the zlib format or incorrect check + value), Z_STREAM_ERROR if the stream structure was inconsistent (for example + next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory, + Z_BUF_ERROR if no progress is possible or if there was not enough room in the + output buffer when Z_FINISH is used.

It should be in the range 8..15 for this + version of the library. Larger values of this parameter result in better + compression at the expense of memory usage. The default value is 15 if + deflateInit is used instead. + + windowBits can also be -8..-15 for raw deflate.

The default value is 8. See zconf.h for total memory usage + as a function of windowBits and memLevel. + + The strategy parameter is used to tune the compression algorithm. Use the + value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a + filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no + string match), or Z_RLE to limit match distances to one (run-length + encoding).

There +are instructions on how to do this at the project site. +http://code.google.com/p/closure-compiler/source/checkout + +Apache Ant is a cross-platform build tool. +http://ant.apache.org/ + +At the root of the source tree, there is an Ant file named +build.xml. To use it, navigate to the same directory and type the +command + +ant jar + +This will produce a jar file called "build/compiler.jar". + + +3) Check out the source and build it with Eclipse. + +Eclipse is a cross-platform IDE. +http://www.eclipse.org/ + +Under Eclipse's File menu, click "New > Project ..." and create a +"Java Project." You will see an options screen. Give the project a +name, select "Create project from existing source," and choose the +root of the checked-out source tree as the existing directory. Verify +that you are using JRE version 6 or higher. + +Eclipse can use the build.xml file to discover rules. When you +navigate to the build.xml file, you will see all the build rules in +the "Outline" pane. Run the "jar" rule to build the compiler in +build/compiler.jar. + + +// +// Running The Closure Compiler +// + +Once you have the jar binary, running the Closure Compiler is straightforward. + +On the command line, type + +java -jar compiler.jar + +This starts the compiler in interactive mode. Type + +var x = 17 + 25; + +then hit "Enter", then hit "Ctrl-Z" (on Windows) or "Ctrl-D" (on Mac or Linux) +and "Enter" again. The Compiler will respond: + +var x=42; + +The Closure Compiler has many options for reading input from a file, +writing output to a file, checking your code, and running +optimizations. To learn more, type + +java -jar compiler.jar --help + +You can read more detailed documentation about the many flags at +http://code.google.com/closure/compiler/docs/gettingstarted_app.html + + +// +// Compiling Multiple Scripts +// + +If you have multiple scripts, you should compile them all together with +one compile command. + +java -jar compiler.jar --js=in1.js --js=in2.js ... --js_output_file=out.js + +The Closure Compiler will concatenate the files in the order they're +passed at the command line. + +If you need to compile many, many scripts together, you may start to +run into problems with managing dependencies between scripts. You +should check out the Closure Library. It contains functions for +enforcing dependencies between scripts, and a tool called calcdeps.py +that knows how to give scripts to the Closure Compiler in the right +order. + +http://code.google.com/p/closure-library/ + +// +// Licensing +// + +Unless otherwise stated, all source files are licensed under +the Apache License, Version 2.0. + + +----- +Code under: +src/com/google/javascript/rhino +test/com/google/javascript/rhino + +URL: http://www.mozilla.org/rhino +Version: 1.5R3, with heavy modifications +License: Netscape Public License and MPL / GPL dual license + +Description: A partial copy of Mozilla Rhino.

+External Communication with JS9 +

External Communication with JS9

+ +

+The JS9 Analysis menu provides flexible support for running a +macro-expanded external analysis command on the Web server and +displaying results in the browser. But there are other scenarios in which +it might be desirable for an external process to communicate with the +JS9 client: + +

    +
  • JS9 might be part of a larger Web-based analysis system +(i.e. instead of the analysis being incorporated into the Analysis +menu). An analysis task might want to query JS9 for its regions. +
  • A Web site might offer "live" tutorials in which JS9 in the +browser is manipulated automatically from the server. +
  • A Web site might wish to modify a JS9 client's user interface based +on the level of expertise of a given user. +
  • A user running JS9 locally might want to interact with her JS9 client from within a local analysis script. +
  • A remote user might want to interact with her JS9 client in a similar way. +
+ +

+If you run the Node.js-based helper (instead of the CGI helper), this +sort of external communication is supported by the js9 script +and its underlying js9Msg.js. The script runs +Node.js with js9Msg.js as its first argument. Using command +line syntax, it will send a single JS9 command to the browser and +return the results: +

+  sh> js9 cmap heat        # change colormap to heat
+  OK
+  sh> js9 cmap             # return the current colormap
+  heat
+
+

+Alternatively, if no command-line arguments are specified, js9 will +enter a "read-line" loop, executing commands as they are input: +

+  sh> js9 
+  JS9> cmap heat
+  OK
+  JS9> cmap
+  heat
+
+

+You also can send multiple commands to the script's standard input: +

+  sh> cat test.reg
+  region circle {"x":588, "y":590, "radius":30, "tags":"source"}
+  region circle {"x":588, "y":590, "radius":10, "tags":"exclude"}
+  region circle {"x":390, "y":430, "radius":50, "tags":"background"}
+  region circle {"x":390, "y":430, "radius":10, "tags":"background,exclude"}
+  sh> cat test.reg | js9    # send regions to JS9
+
+(Note: currently, redirecting to stdin does not appear to display +return messages. We'll fix this in a future release.) + +

+A list of available JS9 commands can be retrieved using the ''help' command: +

+  sh> js9 help
+  analysis     	run/list analysis for current image (ana)
+  colormap     	set/get colormap for current image (cmap)
+  colormaps    	get list of available colormaps (cmaps)
+  help     	get list of available commands
+  helper     	get/set helper connection
+  image     	get name of currently loaded image or display specified image
+  images     	get list of currently loaded images
+  load     	load image(s)
+  pan     	set/get pan location for current image
+  pix2wcs     	get image pixel value for specified wcs position
+  print     	print image window
+  regions     	add region to current image or list all regions (reg, region)
+  scale     	set/get scaling for current image
+  scales     	get list of available scales
+  url     	display a url
+  wcssys     	set/get wcs system for current image
+  wcsu     	set/get wcs units used for current image
+  wcssystems   	get list of available wcs systems
+  wcsunits     	get list of available wcs units
+  wcs2pix     	get wcs position for specified image pixel
+  zoom     	set/get zoom for current image
+
+These are the same commands that are available to the JS9 light-weight +Console window. + +

+One of the most important JS9 commands is the 'region' command, which +will create a new region or display the current region(s): +

+  sh> js9 region circle
+  OK
+  sh> js9 regions
+  ICRS; circle(23:23:26.929, +58:48:50.381, 14.76")
+
+

+Region-specific properties can be supplied in JSON format after the +shape is specified (see http://www.json.org/). You can pass any +property value found in the JS9.Regions.opts object. For example: +

+  sh> js9 region circle '{"x":495, "y":495, "radius":25, "color":"yellow"}'
+  OK
+
+

+The js9 script can talk to a JS9 instance if the script is run from: +

    +
  • the local host running the Web service and back-end helper +
  • the same host that is running the target browser, regardless of +where the helper resides +
+Note that the js9 script on one host cannot communicate with a +target browser on another host (unless the first host is the helper host). +

+If a JS9 instance is connected to a helper on a remote host, you can +use the -helper switch to specify the remote host to +contact. For example, if the helper is running on js9.cfa.harvard.edu, +you can send a command to your instance of JS9 this way: +

+  sh> js9 -helper js9.cfa.harvard.edu region circle
+  OK
+
+

+If more than one instance of JS9 appears on a single Web page, the +-id switch can differentiate between instances. The value of +the id switch is the div id for that JS9 instance. For example, if +two instances of JS9 having div ids of "JS9" and "myJS9" are defined +on the same page, then js9 can communicate with the latter in this way: +

+  sh> js9 -id myJS9 region circle
+  OK
+  sh> js9 -id myJS9 region 
+  ICRS; circle(23:23:26.929, +58:48:50.381, 14.76")
+
+or, from the readline loop: +
+  sh> js9 -id myJS9
+  JS9> region circle
+  OK
+  JS9> region -id myJS9
+  ICRS; circle(23:23:26.929, +58:48:50.381, 14.76")
+
+

+Putting the last two techniques together, you can talk to one of many JS9 +instances on a page connected to a remote helper this way: +

+  sh> js9 -helper js9.cfa.harvard.edu -id myJS9 cmap heat
+  OK
+
+

+A final esoteric note: special considerations are required when a helper +host wants to talk to one of several instances of JS9 connected to the +helper. Being on the same host as the helper, the js9 script is +allowed to send messages to any of these clients. But for security +reasons, it can only send a message to an individual browser, not to all +browsers at once. If the target browser's ip address is known, +the -browser switch can be used to differentiate browsers +running the same page. For example, if you want to talk to the JS9 +client browser on bynars: +

+  sh> js9 -browser bynars.cfa.harvard.edu -id myJS9 region circle
+  OK
+  sh> js9 -browser bynars.cfa.harvard.edu -id JS9 region 
+  ICRS; circle(23:23:26.929, +58:48:50.381, 14.76")
+
+or, from the readline loop: +
+  sh> js9 -browser bynars.cfa.harvard.edu -id myJS9
+  JS9> region circle
+  OK
+  JS9> region 
+  ICRS; circle(23:23:26.929, +58:48:50.381, 14.76")
+
+

+The js9 interface will evolve to meet the needs of the astronomical +community. + +

+Adding a JS9 Server-side Helper +

Adding a JS9 Server-side Helper

+ +

Do You Need a Server-side Helper? Which One?

+JS9 supports server-side analysis on FITS data, allowing you to +execute virtually any command-line analysis program from JS9, run that +analysis command on the back-end, and view results on your Web page. +

+The server-side analysis capability is especially useful for archive +centers, but also can be attractive to individual users who want to +integrate their own data analysis programs into JS9. You configure a +JS9 server-side helper by adding additional switches to the configure +command described in Installing JS9. + +

+JS9 supports two techniques for server-side analysis: you can use your +own Web server as the JS9 back-end helper using CGI calls, or you can +run a separate Node.js-based server to process JS9 back-end +requests. The Node.js server-side helper is faster and more flexible +than the CGI helper (e.g., it supports messaging between the command +line and the browser). However, it obviously requires installation of +Node.js, and uses its own socket port to communicate with the outside +world. You should decide which server-side helper to use before +running configure. Please contact us if you want to discuss the +issues. + +

Consider Adding Analysis Tasks

+

+When configuring server-side analysis, you add server-side analysis tasks +to JS9 (or change the default analysis tasks) by adding or modifying +json files in the analysis-plugins directory (and optionally, +by adding wrapper files to the analysis-wrappers directory.) +See Server-based Tasks for a description of +how to configure server-side analysis tasks for your site. + +

+[Esoteric note: one of the plug-in files in +the analysis-plugins directory is the fits2png.json +plugin. This file specifies the command line for the fits2png +conversion program. If you wish to change that command line, it should +be done before building the system, since the CGI processing +script js9Helper.cgi is generated using this information.] + +

Add Switches to Configure the Server-side Helper

+

+JS9 is built using the standard GNU ./configure; make; make +install technique. When configuring server-side analysis, you will +add switches to the configure command line. The most important of +these switches are: +

+--prefix=[path]         location to install the non-Web programs and scripts
+--with-helper=[type]    type of server-side helper: nodejs, get or post (for CGI)
+
+to specify the program install directory and the type of server-side +helper you are using. Other important switches are: +
+--with-cgidir=[path]     cgi install directory e.g. /var/www/public_html/cgi-bin
+--with-cgiurl=[url]      cgi url relative to the Web root, e.g. ./cgi-bin/js9
+--with-cgixpath=[dirs]   directories to add to cgi path
+--with-funtools=[path]   funtools directory for build e.g. /soft/funtools
+--with-png=[path]        directory containing lib/png e.g. /usr/local
+
+ +

+Non-Web files, programs, and scripts (e.g., js9helper and fits2png) +will be installed in accordance with the --prefix=[dir] switch. +The default is /usr/local. + +

+If you want to utilize the Node.js-based helper, you do not have to +add any special nodejs switches. If you want to utilize a CGI-based +back-end, you must specify the --with-cgidir +and --with-cgiurl switches on the configure command +line. Optionally, you also can specify the +--with-cgixpath switch if you want to add directories to the CGI path: + +

    +
  • The --with-cgidir switch specifies the directory into which to +install the js9Helper.cgi wrapper script. That script is generated by +the build. All CGI requests are processed through this js9Helper.cgi wrapper. + +
  • The --with-cgiurl switch specifies the URL of the +js9Helper.cgi script relative to your Web document root. The +value of this switch is combined with the CGI wrapper filename and the +result stored in the js9Prefs.json file, telling JS9 how to call the +CGI back-end helper script. + +
  • The --with-cgxpath switch specifies a semi-colon delimited +list of directories to add to the CGI path. You can use this switch to +make accessible the executables that will be used in your CGI +processing. Of course, setting up the CGI path also can be done in +many ways, e.g., inside your analysis wrapper scripts or even in the +Web server itself. +
+ +

+The build of the JS9 server-side tpos program (which converts FITS +files to the JS9 representation file) requires the libpng library. If +libpng is not already installed on your system, it is available at: +

+    http://www.libpng.org/pub/png/libpng.html
+
+Of course, Linux users can install libpng in the "usual way", e.g. for CentOS: +
+    sudo yum install libpng-devel
+
+Any relatively modern version of the png library should suffice +(subject to security fixes, etc.) +

+[Esoteric note: It sometimes happens that incompatible png versions +1.2 and 1.5 are installed on the same machine. This can lead to link +errors if the include file from one version is used with the libraries +from another. If this happens on your system, you can tell configure +where to look for the libraries and include files of one version only +using the --with-png=[dir] switch.] + +

+The build of the JS9 tpos program also requires the funtools package. +Funtools is available on the JS9 Web site: +

+    http://js9.si.edu
+
+To tell configure where funtools libraries and executables are +located, use the --with-funtools=[dir] switch, +e.g. --with-funtools=/usr/local will find the funtools libraries in +/usr/local/lib. +

+Example configure commands are shown below for a typical Linux Apache setup +and for a personal Mac setup: +

+  linux-cgi)
+  ./configure 	--prefix=/soft/saord					\
+		--with-helper=get					\
+		--with-webdir=/var/www/htdocs/js9			\
+		--with-cgidir=/var/www/cgi-bin/js9			\
+		--with-cgiurl=./cgi-bin/js9				\
+		--with-cgixpath=/soft/saord/bin				\
+		--with-funtools=/soft/saord				\
+		--with-png=/soft/saord/linux64				\
+  		CC=gcc $*
+
+  mac-nodejs)
+  ./configure 	--prefix=$HOME						\
+		--with-helper=nodejs					\
+		--with-webdir=/Users/me/Sites/js9			\
+		--with-funtools=/usr/local				\
+		CC=gcc $*
+
+
+In these examples, the JS9 Web files (JavsScript, CSS etc.) will be +installed in a js9 sub-directory of htdocs in the /var/www directory +or in the Mac user's personal Sites directory. JS9 CGI files will be +installed in a subdirectory of the cgi-bin directory. C programs and +shell scripts will be installed in sub-directories of the user's home +directory. Funtools is located in /soft/saord or /usr/local (i.e. with +executables in /soft/saord/bin and libraries in /soft/saord/lib. etc.). + +

Build the JS9 System

+

Once the configure arguments are set up, you run configure, etc. +as described in the basic install instructions at: +Installing JS9. +

+Some additional notes on getting the server-side helpers working are +added below. + +

Notes on the CGI-based Server-side helper

+ +

+All JS9-specific CGI files and programs should have been built and installed +during the standard configure, make, make install process. In +particular, the globalOpts.helperType variable in the +js9Prefs.json file should have a value of "get" (or you can use +"post", if you reset the value manually. Not sure why you would do +this but ...) + +

+Of course, you must now ensure that your Web server can run the +js9Helper.cgi script successfully to execute JS9 CGI commands. Normal +Web debugging techniques come into play here: check the CGI section of +your Web server's configuration file and review the Web access and +error logs. If you continue to have problems, please let us know and +we will try to help. + +

Notes on Installing the Node.js-based Server-side helper

+

+The Node.js server-side helper is noticeably faster than CGI. It also +offers more power and flexibility, e.g., the node server supports +external control of the browser from the command line via the + and it's underlying js9Msg facility +(see

  • External Messaging with JS9 for +more information). However, Node.js requires that you open another +Internet port to the outside world. + +Node is available at: +
    +    http://nodejs.org/
+
    +Once Node.js is installed, you must start the server-side helper from the JS9 +Web install directory: +
    +    node js9Helper.js >& node.log &
+
    +Unlike CGI, Node can be run as any user: it does not have to be run as +the http daemon user. It certainly should not be run as root! We run +it as a non-privileged user with sufficient permissions to run analysis +programs. In any case, it should be run with its Unix PATH set to +include the directory containing the JS9 helper program, as well as +any analysis programs that will be executed by the JS9 server-side +helper when requested by the client. + +

    +Clients will automatically connect to the Node.js helper when an image +is loaded into JS9. The server-side helper listens on a port specified +in the js9Prefs.json file by the globalOpts.helper.Port value. The +default is 2718, but you can change this to any open port you like. + +

    +Installing JS9 +

    Installing JS9

    + +

    Summary for the Impatient

    +
      +
    • retrieve and unpack the source code tar file or clone the js9 repository +
    • JS9 is now ready for drag-and-drop image files using the file:// URI +
    • to install JS9 into a Web server tree, run configure with this switch: +
      +  ./configure --with-webdir=[path] where path specifies the location to install the JS9 Web files
+
      +
    • edit the js9Prefs.js to set up your site-specific JS9 parameters +
    • build, install, clean up: make; make install; make clean +
    + +

    Retrieve and Unpack the Source Code Tar File

    +

    +The current JS9 source tar file is available at: +

    +    http://js9.si.edu
+
    +The source tar file will unpack into a js9-[version] directory with +the usual tar command, e.g: +
    +    tar xfz js9-[version].tar.gz
+
    +You also can clone JS9 from github: +
    +    https://github.com/ericmandel/js9
+
    + +

    Run JS9 using the file:// URI

    +Once the tar file is unpacked, you should be able to load any of the +js9*.html Web pages into your browser using the file:// URI. For +example, if you unpacked the tar file into /Users/me on a Mac, then +you can point your browser to: +
    +    file:///Users/me/js9-[version]/js9basics.html
+
    +to see the basic JS9 demo page. You then can drag any FITS image file onto +the JS9 display and view it, change contrast/bias, colormaps, +scale, create regions, etc. Furthermore, if you load the imexam Web page: +
    +    file:///Users/me/js9-[version]/js9imexam.html
+
    +you can move a region around and run browser-based analysis as +the region changes. +

    +NB: The file://URI does not work in Google Chrome: Chrome doesn't +permit a local HTML file to read other local files. The workaround is +to start Chrome with the --allow-file-access-from-files switch: +

    +    # Linux:
+    chrome --allow-file-access-from-files
+    # Mac:
+    open /Applications/Google\ Chrome.app --args --allow-file-access-from-files
+
    +Firefox and Safari do not have this restriction. +

    +If you just want to run JS9 in this simple way, you are done. However, +you might want to edit the js9Prefs.json file to set up default values +for colormaps, scaling, etc. See: +JS9 Site Preferences for a +description of the available parameters. + +

    Do You Want to Install JS9 in a Web Server?

    If you want to +run JS9 in a "real" Web server tree, build and install the JS9 tools and +files using the standard GNU ./configure; make; make install +technique. You should run configure with +the --with-webdir=[path] switch, which specifies the directory +into which the JS9 Web files (JavaScript, CSS, etc.) will be +installed. We recommend that this directory only contain the +installed JS9 files, i.e. that you install JS9 into its own +self-contained directory. This will make upgrading to new versions +much easier. + +

    Do You Want to Configure Server-side Analysis?

    +

    +JS9 supports server-side ("back-end") analysis on FITS data using a +server-side helper. This capability allows you to execute virtually +any command-line analysis program from JS9. The analysis command is +run on the back-end server and results viewed on your Web page. You can +utilize your own Web server as the JS9 back-end helper using CGI +calls, or you can run a separate Node.js-based server to process JS9 +back-end requests. The server-side analysis capability is especially +useful for archive centers, but also can be attractive to individual +users who want to integrate their own data analysis programs into JS9. +

    +In addition, JS9 supports communication with external processes via the +js9 script. This capability requires the configuration of a +Node.js-based server-side helper. +

    +You configure a JS9 back-end helper by adding additional switches to +the configure command. See: +Installing a Server-side Helper +for details. + +

    Build the JS9 System

    +Once you have decided on the configuration of your JS9 system, run +configure to generate various build files: +
    +  ./configure [your JS9 switches]
+
    +

    +and then build the JS9 system using the make command: +

    +   make
+
    + +

    Finalize Your Site Preferences

    +

    +When JS9 is loaded into your browser, it reads a file called +js9Prefs.json from the JS9 Web directory. This file contains +various default settings for JS9, e.g. default colormap and scale for +image display. Feel free to edit this file to set up your own +site-specific parameters. See +JS9 Site Preferences for a +description of the available parameters. + +

    Install the JS9 System

    +

    When the build is completed, you can install the JS9 into your Web tree: +

    +    make install
+
    +

    +and then clean up the build directory using the command: +

    +    make clean
+
    +

    Optionally Install the JS9 Test Data Files

    +

    +If you want to display our test data files in the JS9 demo pages, +retrieve the JS9 data file tar file from the JS9 Web site: +

    +    http://js9.si.edu
+
    +and untar it into the JS9 Web install directory. This will create +sub-directories containing the image data. + +

    +

    JS9 Known Issues

    + +
      +
    1. All platforms, especially Chrome (June 21, 2014 : NOT resolved) +

      +Available memory can be a problem when loading very large gzip'ed FITS +files, especially in 32-bit Chrome. JS9 currently reads the entire +FITS file or gzip'ed file and inflates parts as needed. It can process +files up to approx. 200Mb in size before Chrome runs out of heap +space. Note that Chrome often will load an ungzip'ed FITS file in +cases where the gzip'ed file fails (though there still are upper +limits on the total space available). We hope that the 64-bit version +of Chrome (in early Canary release as of 7/1/2014) will alleviate +these problems. Otherwise, we will take a more drastic approach to +memory management within JS9 (at the expense of speed). + +

    2. All platforms (June 21, 2014 : NOT resolved) +

      +The zscale algorithm requires allocation of a fixed-size static memory +buffer. We have limited the size of this secondary buffer to be large +enough to handle a 4096 x 4096 x 4-byte image. If your image is larger +than this, zscale will not run. We will revisit the size of the +static buffer as we gain more experience with the size of images being +analyzed (or eventually rewrite the algorithm). + +

    3. All platforms (June 13, 2014 : NOT resolved) +

      +When resizing a box region in one direction only (i.e., width or +height), the width of the region's border will be different in each +direction. This is due to the underlying graphics algorithm used to +resize the region, which changes the scale factor in each direction +individually and ties the border width to that scale factor. We will +fix this in a future release. + +

    4. All platforms using Chrome (March 27, 2014 : resolved) +

      +One of the simplest ways to use JS9 locally is by means of the file:// +URL scheme, e.g., point your browser to file:///home/me/js9/js9basics.html. +

      +This does not work in Google Chrome because Chrome does not permit a +local HTML file to read other local files. You can read a relatively +emotional argument about this restriction at: +

      +    https://code.google.com/p/chromium/issues/detail?id=37586
+
      +

      +The workaround is to start Chrome with the +--allow-file-access-from-files switch. On Linux: +

      +    chrome --allow-file-access-from-files
+
      +On a Mac: +
      +    open /Applications/Google\ Chrome.app --args --allow-file-access-from-files
+
      + +
    5. All platforms (May 20, 2013: resolved) +

      +If the "load image" command is part of a group of commands passed to +the js9 script, a race condition can occur when subsequent commands +are executed before the image is fully loaded. To avoid this problem, +images should be loaded in a separate js9 command and the load status +checked for completion before proceeding to manipulate the image. See +the js9load script for details (or just use the script itself +to load images). (Technical details: images are loaded asynchronously, +so that other parts of the Web page are available during the load +process. A synchronous load could freeze the Web page while +loading. To avoid this situation, external processes should use the +"status load" command to check for a completed load before sending +further processing commands). + +

    +Local (Browser-Based) Analysis Tasks +

    Adding Local (Browser-Based) Analysis Tasks to JS9

    + +

    +JS9 supports the ability to perform local analysis, i.e. tasks +executed in your browser (not on the back-end server). This is +accomplished by offering access to the image data and region +information via a +JS9 Public API. Obviously, all of JS9 +JavaScript code is available to you within a Web page, but the public +API is designed to stable and well-documented. + +

    +Adding Simple Analysis Tasks to Your Web Page +

    +For simple analysis (i.e., no mouse or keyboard event processing), it +often is sufficient to define GUI elements directly on the Web page, +adding Javascript code to interact with these elements and call the +public JS9 functions as needed. In particular, +the JS9.GetImage() function will return a handle for the +currently displayed image and the the various JS9.Region +functions allow you to manipulate regions. These routines are +described in the JS9 Public API. + +

    +The js9onchange.html demo Web page illustrates these simple +capabilities. It shows how to run a task every time a region +changes, i.e. when it is moved, resized, or deleted. This is +accomplished by setting the JS9.Regions.opts.onchange +parameter to a function (if you are setting via JavaScript) or a +string routine name (if you are setting via json in the prefs file): +

    +    // via JavaScript    
+    JS9.Regions.opts.onchange = myRegionChanged;
+
    +or: +
    +    // from within js9Prefs.json
+    { ... "Regions.opts":  {"onchange": "myRegionChanged"} ... }
+
    +The calling sequence of the xeqonchange function is: +
    +    function myRegionChanged(im, xreg)
+
    +where im is the image handle of the currently displayed image, and +xreg is an object containing information about the changed region. +See below for a description of the returned region +object. Note that you can turn off region change processing for +individual regions or for all regions by means of the xeqonchange +menu option in a given region's context menu or the global Regions menu, +respectively. + +

    +The js9onchange.html demo Web page also shows how +server-side JS9 analysis tasks can be executed directly from the +Web page using HTML elements (buttons, forms, etc.) instead of the +Analysis menu. See Server-side +Analysis Tasks for more information. + +

    +

    Adding Plugins to Your Web Page

    +

    +For anything other than the simplest analysis, you can write a JS9 +Plugin module. A plugin is a Javascript module that contains +a constructor function to create a plugin GUI, and, optionally, +one or more event callbacks to process desired events. At the +end of the file, the plugin calls RegisterPlugin() to make +itself known to JS9. Plugin modules should be stored in the +js9/plugins directory (or in a sub-directory therein) and should be +loaded into JS9-enabled Web pages after js9.js itself is loaded. + +

    +To create instances of the plugin GUI, the constructor function gets +called for each plugin div defined on the Web page. +The this context is seeded with a few JS9 properties, including: +

      +
    • this.div: the DOM element representing the div for this plugin +
    • this.divjq: the jquery object representing the div for this plugin +
    • this.id: the id of the div (or the plugin name as a default) +
    • this.winType: "div" (in-page div element) or "light" (from view menu) +
    • this.winHandle: handle returned from light window create routine +
    • this.display: the display object associated with this plugin +
    • this.plugin: plugin class object (contains user opts in opts sub-object) +
    • this.status: "active" or "inactive" or undefined +
    +The most important of these properties is the div property +specifying the DOM element of the containing div. You add your GUI +(HTML elements) to this.div and use the events to control +the action. The type property tells you whether the instance is +being created for an in-page div element or from the View menu, in +case configuration is different for these cases. +The plugintest.js module +provides a fairly complete example and should be studied in +conjunction with this help page. + +

    +A JS9 plugin is registered at the end of the module using +the JS9.RegisterPlugin() public routine: +

    +  JS9.RegisterPlugin(xclass, xname, func, opts)
+
    +where: +
      +
    • xclass: class of the plugin +
    • xname: name of plugin +
    • func: the constructor function +
    • opts: an object containing plugin options +
    +The xclass and xname values together make up +the class of the div element. Thus, if the plugin xclass +is "JS9" and the plugin xname is "Menubar", then the div which +will hold the menubar has a class of "JS9Menubar". Note that these +strings must adhere to CSS grammar rules, e.g. start with a letter, +followed by letters, numbers, dashes and underscores, no spaces allowed. +

    +This class/name separation has been made so that multiple plugins can +be written as part of one class and processed together as part of that +class, e.g., displayed together in the View and Help menus. +

    +The optional opts object contains the following elements, +all of which also are optional: +

      +
    • onmouseup: callback function(im, ipos, evt) for mouse up events +
    • onmousedown: callback function(im, ipos, evt) for mouse down events +
    • onmousemove: callback function(im, ipos, evt) for mouse move events +
    • onmouseover: callback function(im, ipos, evt) for mouse over events +
    • onmouseout: callback function(im, ipos, evt) for mouse out events +
    • onkeypress: callback function(im, ipos, evt) for keypress events +
    • on[layer]change: function(im, xreg) for when a shapes changes in a layer (e.g. onregionschange for region changes) +
    • onimageload: callback function(im) when an image is loaded +
    • onimagedisplay: callback function(im) when an image is (re)displayed +
    • divArgs: [arg1, arg2, ...] arguments passed to div-based constructor +
    • menuItem: menuname in specified menu (default is View menu) +
    • menu: add plugin to this menu (only View or Analysis right now!) +
    • winDims: [width, height] +
    • winTitle: string +
    • toolbarHTML: string +
    • toolbarSeparate: boolean +
    • help: path html file for help, relative to js9/plugins directory +
    +

    +Each of the callback functions are routines which get executed when +the specified event takes place. The routines are passed the following +arguments: current image object handle, the 1-indexed image position +of the mouse and, for all but the on[layer]change, +onimageload and onimagedisplay routines, the original event +that triggered the callback. The on[layer]change callback gets +passed the same xreg object as is used for the +JS9.Regions() routine and the JS9.Regions.opts.onchange +parameter. See below for a description of its contents. + +

    +Holding down the Shift key (where available) will turn off execution of all +mouse event callbacks. This allows you to move the mouse to a specific +location, and then move away without triggering a callback. The +xeqonchange menu option in the Regions menu and each region's +context menu can be used to turn off execution of the region onchange callback. +The former does this globally, the latter only for the specific region. + +

    +The divArgs is an array specifying arguments to pass to the constructor +function, when a div element is found in the Web page. For example, the Panner +and Magnifier plugins pass a width and height to the constructor in this way. + +

    +The menuItem is a string which specifies the name that will be +used in the View menu when a plugin div is not found on the Web +page. If no menuItem is specified, the plugin will not appear +in the View menu. + +

    +Furthermore, the menu property can be used to change the menu +in which the above-mentioned menuItem plugin will be +placed. For example, an Imexam plugin situates +its plugins in the Analysis menu instead of the View menu. NB: At the +moment, only the View and Analysis menus are supported +for placement. + +

    +The winDims is an array specifying the width and height of the +light window that will get created for this plugin via the View menu. +The winTitle is a string specifying the title of the light window. +The default is no title. + +

    +You can add HTML (e.g. command buttons) to the light window titlebar +by putting an HTML string into the toolbarHTML property. The +panner and magnifier use this technique to add zoom buttons. You also +can add HTML onto a Web-page plugin div, but in this case, where the +HTML is placed depends on the value of the toolbarSeparate +property. If the value of toolbarSeparate is true, then a +titlebar is created above the plugin and the HTML is added to it. +Otherwise, the HTML is placed in top of the plugin itself. + +

    +The help property specifies the pathname of an html file that will +be placed in the Help menu. This pathname should be relative to +the plugins directory. + +

    +Within a callback, you can use the JS9 Public API to manipulate data, as +detailed in the JS9 Public API. + +

    Configuring JS9 Site Preferences

    + +

    +JS9 supports a site configuration file that is read after the +JavaScript variables are loaded but before JavaScript code is compiled +and executed. This file allow you to tailor JS9 to meet the needs of +your site without having to modify the js9.js file directly. + +

    +To support site configuration, JS9 tries to load a json file called +js9Prefs.json from the same server on which the main +js9-[version].js file resides. The file will be looked for first in +the same directory as the Web page and then in the js9 install directory. + +

    +This preference file can be used to override the default parameter +settings for JS9. A look through the beginning of JS9 code will show +a number of Javascript objects containing these default +parameters. They all have names ending in Opts, +i.e. JS9.imageOpts, JS9.analysisOpts, etc. A description of some of +these objects is given below: + +

      +

    1. JS9.globalOpts: this JavaScript object contains global +information, including parameters concerned with the back-end services +used by JS9. Currently, it allows you to specify the helperPort +on which to connect. Note that this same preference file is read the +Node-based js9Helper, so changing the helper port in this file will +change both the client and server. + +

      +

    2. JS9.imageOpts: This JavaScript object contains initial +values for image parameters such as: contrast, bias, +whether to invert the +colormap, colormap, scale, WCS system , WCS +units, whether to display value/position, and whether to +list regions when they change (listonchange). + +

    3. JS9.analOpts This JavaScript object contains +the dataDir option, which specifies the pathname prefix to add +to each FITS filename instead of the pathname stored in the PNG +file. You can set this variable if you have moved the location of the +raw FITS files after generating the PNG files. + +

    4. JS9.Regions.opts: This JavaScript object contains default +values for regions, including the initial size of various regions, +initial inner and outer radii for annuli, initial angle, etc. + +

    5. JS9.menuButtonOptsArr: this JavaScript array of objects allows +you to change and re-arrange which menu options are provided. If you +prefix the name of a menu option with '#', that option is disabled. + +

    +In addition to the above-mentioned objects, the preference file can be +used to set some internal variables. The JS9.DEBUG parameter is an +example, as shown in the default preference file. Ordinarily, users +need not be concerned with these variables. + +

    +The JS9 Public API +

    The JS9 Public API

    + +

    +The JS9 Public API provides a JavaScript programming interface for +interacting with JS9. Obviously, all of JS9 JavaScript code is +available to you within a Web page, but the public API is designed to +stable and well-documented for users and Web designers. It also will +provide the basis for planned language bindings (python, perhaps C/Fortran). +

    +In general, the public API routines act on the current image being +displayed in the default JS9 div element. Since most Web pages will +have only a single JS9 div element, this behavior is usually what you +want. It parallels DS9's behavior in which XPA commands act on the +currently displayed image. For example, to change the colormap of the +current image, use: +

    +  JS9.SetColormap("cool");
+
    + +

    +However, for cases where multiple JS9 div elements are defined on a +single page, you can specify the specific div element to process by +adding an display object argument to the calling sequence with +a single display property: +

    +  {display: [div_id]}
+
    +where [div_id] is the id of the target JS9 div element. For example, +if two JS9 divs with ids "JS9" and "myJS9", respectively, are present +on a single Web page, you can set the colormap of the second one this way: +
    +  JS9.SetColormap("cool", {display: "myJS9"})
+
    +Note that this display object contains only the display +property and always is specified as the final argument in a call. +

    +The display property can specify an image handle instead of +a JS9 div element id. This is a minor optimization for cases where you want +to call a routine such as JS9.WCSToPix() or JS9.PixtoWCS() many times: +

    +  var im = JS9.GetImage({display: "myJS9"});
+  for(i=0; i<1000; i++){
+    x = ...
+    y = ... 
+    wcs = JS9.PixtoWCS(x, y, {display: im});
+    console.log("%s %s -> %s %s", x, y, wcs.ra, wcs.dec);
+  }
+
    +Passing the image handle will speed up processing very slightly, but +it makes us programmers feel much better. +

    +The optional display object argument is not explicitly +documented in the routines below (except as an example +in JS9.Load()), but it is always available. + +

    +Choose from the following sections: +

    + +

    +

    +Loading Images +
    + +

    +● Load an image into JS9 +

    +JS9.Load(url, opts, func) +

    +where: +

      +
    • url: url to load +
    • opts: object containing image parameters +
    • func: optional function to call when image load is complete +
    +

    +Load a FITS file or a PNG representation file into JS9. +To override default image parameters, pass the image opts argument: +

    +    href='javascript:JS9.Load("png/m13.png", {scale:"linear", colormap:"sls"});'
+
    +

    +If a callback function is specified, it will be called after the image +is loaded: +

    +    href='javascript:JS9.Load("fits/3c273.fits", {scale: "linear"}, func);'
+
    +The image handle is passed as the first argument to the callback. +

    +To load an image into a specified display, pass the display object as the last argument: +

    +    href='javascript:JS9.Load("fits/3c273.fits", {scale: "linear"}, {display: "myJS9"});'
+
    +

    +

    +See Displaying Your Data for further discussion of +how to use this routine. + +

    +● Load an image into a light window or a new (separate) window +

    +JS9.LoadWindow(url, opts, type, html, winopts) +

    +where: +

      +
    • url: url to load +
    • opts: optional object containing image parameters +
    • type: "light" or "new" +
    • html: html for the new page (default is to display a menubar above the image) +
    • winopts: for "light", optional dhtml window options +
    +This routine will load an image into a light-weight window or an entirely new +window. The url and opts arguments are identical to the standard +JS9.Load() call. The type argument determines whether to create +a light-weight window or a new (separate) window. +

    +By default, the new window will contain a Menubar above an image display area: +

    +    <div class='JS9Menubar' id='[id]Menubar'></div>
+    <div class='JS9' id='[id]'></div>
+
    +You can use the html argument to supply different Web page elements +for the window. Furthermore, if you create a light window, a default +set of DynamicDrive dhtmlwindow parameters will be used to make the +window the correct size for the default html: +
    +    "width=512px,height=542px,center=1,resize=1,scrolling=1"
+
    +You can supply your own parameters for the new dhtmlwindow using the +winOpts argument. See: + +DynamicDrive for more information about their light-weight window. +

    +See js9create.html for examples of how to use this routine. + +

    +● Load one or more images when the Web page is ready +

    +JS9.Preload(url1, opts1, url2, opts2, ... url2, optsn) +

    +where: +

      +
    • url: url to load +
    • opts: optional object containing image parameters +
    +This routine will pre-load images into a JS9 display when the Web page +is loaded and JS9 is initialized. It can be added to the Web page body +element using the onload() JavaScript call or called directly in a +JavaScript init routine. See index.html and js9preload.html for examples. + +

    +

    +Working with Images +
    +

    + +

    +● Get image handle for the current image +

    +im = JS9.GetImage() +

      +
    • im: image handle +
    +

    +The routine returns the image handle associated with the current image. +

    +The returned image handle can be passed in the display object. This +is marginally more efficient than the default behavior, which is to +determine the current image for each call. + +

    +● Get image data and auxiliary info for the specified image +

    +imgdata = JS9.GetImageData(dflag) +where: +

      +
    • dflag: true if you want the data returned (as an HTML5 typed array) +
    +

    +The image data object contains the following information: +

      +
    • id: the id of the file that was loaded into JS9 +
    • file: the file or URL that was loaded into JS9 +
    • source: "fits" if a FITS file was downloaded, "fits2png" if a representation file was retrieved +
    • imtab: "image" for FITS images and png files, "table" for FITS binary tables +
    • width: x dimension of image +
    • height: y dimension of image +
    • bitpix: FITS bits/pixel of each image element (8 for unsigned char, 16, 32 for signed integer, -32 or -64 for float) +
    • header: JavaScript object containing FITS header values +
    • data: if dflag is true, a pointer to HTML5 typed array +containing image data +
    +This call returns raw data for subsequent use in local analysis tasks. The data +buffer is a reference to the real data, so be careful about changing values. +

    +Given a FITS-standard 1-indexed image pixel x,y, you can find the data value +at that location using: +

    +    val = obj.data[Math.floor(y-0.5) * obj.width + Math.floor(x-0.5)];
+
    +Note the need to integerize the x and y values: JavaScript arrays are +objects and so floating point array indices do not get truncated +automatically as in C. They will return null values. +

    +Also note that since we need 0-based data array indexes, we subtract 1 from +the 1-based image position. But then we must add 0.5 before rounding because +by convention, x.0, y.0 is the middle of the pixel. +

    +● Display an image +

    +JS9.DisplayImage(step) +

    +where: +

      +
    • step: starting step to take when displaying the image +
    +The display steps are: "colors" (remake color data when cmap has changed), +"scaled" (rescale data values), "primary" (convert scaled data values +to color values), and "display" (write color values to the Web page). +

    +The default step is "primary", which displays the image without recalculating +color data, scaled data, etc. This generally is what you want, unless you have +explicitly changed parameter(s) used in a prior step. + +

    +● Re-read the data from a FITS file and re-display +

    +JS9.RefreshImage(fitsobj, func) +

    +where: +

      +
    • fitsobj: new FITS object from which to take raw data for display +
    • func: optional function to call when image load is complete +
    +This routine can be used, for example, in laboratory settings where +data is being gathered in real-time and the JS9 display needs to be +refreshed periodically. The call takes a fits object as the second +argument. It will refresh the display using the new data contained in that +object. +

    +The fits object should contains the following properties: +

      +
    • naxis: number of axes in the image +
    • axis: array of image dimensions for each axis +
    • bitpix: FITS bitpix value +
    • image: typed data array containing current image data +
    • head: object containing header keywords as properties +
    • card: string version of the header with comments (optional) +
    • dmin: data min (optional) +
    • dmax: data max (optional) +
    + +

    +● Clear the image from the display and mark resources for release +

    +JS9.CloseImage() +

    +Each loaded image claims a non-trivial amount of memory from a finite +amount of browser heap space. For example, the default 32-bit version +of Google Chrome has a memory limit of approximately 500Mb. If you are +finished viewing an image, closing it tells the browser that the +image's memory can be freed. In principle, this is can help reduce +overall memory usage as successive images are loaded and +discarded. Note, however, that closing an image only provides a hint +to the browser, since this sort of garbage collection is not directly +accessible to JavaScript programming. +

    +Some day, all browsers will support full 64-bit addressing and this problem will +go away ... +

    +● Get the image colormap +

    +cmap = JS9.GetColormap() +

    +returns: +

      +
    • cmap: string containing colormap name +
    +Get the current colormap name. + +

    +● Set the image colormap +

    +JS9.SetColormap(cmap, [contrast, bias]) +

    +where: +

      +
    • cmap: colormap name +
    • contrast: contrast value (range: 0 to 10) +
    • bias: bias value (range 0 to 1) +
    +Set the current colormap, contrast/bias, or both. This call takes one +(colormap), two (contrast, bias) or three (colormap, contrast, bias) +arguments. + +

    +● Get the image scale +

    +scale = JS9.GetScale() +

    +returns: +

      +
    • scale: string containing scale name +
    +Get the current scale name. + +

    +● Set the image scale +

    +JS9.SetScale(scale, smin, smax) +

    +where: +

      +
    • scale: scale name +
    • smin: scale min value +
    • smax: scale max value +
    +Set the current scale, min/max, or both. This call takes one +(scale), two (smin, max) or three (scale, smin, smax) arguments. + +

    +● Get the image zoom factor +

    +zoom = JS9.GetZoom() +

    +returns: +

      +
    • zoom: floating point zoom factor +
    +Get the zoom factor. + +

    +● Set the image zoom factor +

    +JS9.SetZoom(zoom) +

    +where: +

      +
    • zoom: floating or integer zoom factor or zoom directive string +
    +The zoom directives are: +
      +
    • x[n]|X[n]: multiply the zoom by n (e.g. "x2") +
    • /[n]: divide the zoom by n (e.g. "/2") +
    • in|In: zoom in by a factor of two +
    • out|Out: zoom out by a factor of two +
    • toFit|ToFit: zoom to fit image in display +
    + +

    +● Get the image pan position +

    +ipos = JS9.GetPan() +

    +returns: +

      +
    • ipos: image position object containing x and y image +coordinate values +
    +Get the current pan position in image coordinates. + +

    +● Set the image pan position +

    +JS9.SetPan(x, y) +

    +where: +

      +
    • x: x image coordinate +
    • y: y image coordinate +
    +Set the current pan position using image coordinates. +Note that you can use JS9.WCSToPix() and JS9.PixToWCS() to +convert between image and WCS coordinates. + +

    +● Get the display coordinates from an event +

    +dpos = JS9.EventToDisplayPos(evt) +

    +where: +

      +
    • evt: a JavaScript event +
    +returns: +
      +
    • dpos: display position object containing x and y display +coordinate values +
    +If you define your own event callbacks, you can use this routine to convert +the event position to a display position, which can then be used to get the +image position (see below). + +

    +● Get the image coordinates from the display coordinates +

    +ipos = JS9.DisplayToImagePos(dpos) +

    +where: +

      +
    • dpos: display position object containing x and y display +coordinate values +
    +returns: +
      +
    • ipos: image position object containing x and y image +coordinate values +
    +Note that image coordinates are one-indexed, as per FITS conventions, while +display coordinate are 0-indexed. +

    +● Get the display coordinates from the image coordinates +

    +dpos = JS9.ImageToDisplayPos(ipos) +

    +where: +

      +
    • ipos: image position object containing x and y image +coordinate values +
    +returns: +
      +
    • dpos: display position object containing x and y display +coordinate values +
    +Get display (screen) coordinates from image coordinates. Note that +image coordinates are one-indexed, as per FITS conventions, while +display coordinate are 0-indexed. + +

    +● Update value/position information +

    +valpos = JS9.UpdateValpos(ipos, display) +

    +where: +

      +
    • ipos: image position object containing x and y image +coordinate values +
    • display: boolean value specifying whether the info box display should be updated (default is true) +
    +This routine determines the data value at a given image position +and returns an object containing the following information: +
      +
    • ix: image x coordinate +
    • iy: image y coordinate +
    • isys: image system (i.e. "image") +
    • px: physical x coordinate +
    • py: physical y coordinate +
    • psys: currently selected pixel-based system (i.e. "image" +or "physical") for the above px, py values +
    • ra: ra in degrees (if WCS is available) +
    • dec: dec in degrees (if WCS is available) +
    • wcssys: wcs system (if WCS is available) +
    • val: floating point pixel value +
    • val3: pixel value as a string truncated to 3 decimal digits +
    • vstr: string containing value and position info +
    • id: id of the image +
    • file: filename of the image +
    • object: object name of the image from the FITS header +
    + +

    +● Get the current WCS units +

    +unitsstr = JS9.GetWCSUnits() +

    +returns: +

      +
    • unitstr: "pixels", "degrees" or "sexagesimal" +
    +Get the current WCS units. + +

    +● Set the current WCS units +

    +JS9.SetWCSUnits(unitsstr) +

    +where: +

      +
    • unitstr: "pixels", "degrees" or "sexagesimal" +
    +Set the current WCS units. + +

    +● Get the current World Coordinate System +

    +sysstr = JS9.GetWCSSys() +

    +returns: +

      +
    • sysstr: current World Coordinate System ("FK4", "FK5", "ICRS", +"galactic", "ecliptic", "image", or "physical"); +
    +Get current WCS system. + +

    +● Set the current World Coordinate System +

    +JS9.SetWCSSys(sysstr) +

    +where: +

      +
    • sysstr: World Coordinate System ("FK4", "FK5", "ICRS", +"galactic", "ecliptic", "image", or "physical") +
    +Set current WCS system. The WCS systems are available only if WCS +information is contained in the FITS header. Also note that "physical" +coordinates are the coordinates tied to the original file. They are +mainly used in X-ray astronomy where individually detected photon +events are binned into an image, possibly using a blocking factor. +For optical images, image and physical coordinate usually are identical. + +

    +● Convert image pixel position to WCS position +

    +wcsobj = JS9.PixToWCS(x, y) +

    +where: +

      +
    • x: x image coordinate +
    • y: y image coordinate +
    +returns: +
      +
    • wcsobj: world coordinate system object +
    +

    +The wcs object contains the following properties: + +

      +
    • ra: right ascension in floating point degrees +
    • dec: declination in floating point degrees +
    • sys: current world coordinate system being used +
    • str: string of wcs in current system ("[ra] [dec] [sys]") +
    + +

    +● Convert WCS position to image pixel position +

    +pixobj = JS9.WCSToPix(ra, dec) +

    +where: +

      +
    • ra: right ascension in floating point degrees +
    • dec: declination in floating point degrees +
    +returns: +
      +
    • pixobj: pixel object +
    +The pixel object contains the following properties: + +
      +
    • x: x image coordinate +
    • y: y image coordinate +
    • str: string of pixel values ("[x]" "[y]") +
    + +

    +

    +Working with Regions +
    +

    +Spatial regions of interest are a crucial part of astronomical data +analysis. The regions layer is a special case of the more generalized +shape layers, automatically created by JS9 to support the options in +the Regions menu, as well as local and server-side data analysis +using regions. +

    +The regions layer has the special property that, by default, +its z-index is higher than other shape layers, so that regions +are displayed on top of other shape layers. +

    +Note that the GetRegions(), ChangeRegions(), RemoveRegions() calls +all take a regions specification as the second argument, which can be +any of the following (in order of precedence): +

      +
    • "all": all regions +
    • [id]: a specific region id returned by JS9.AddRegions() +
    • "selected": the selected region (or all regions in the selected group) +
    • [color]: all regions having the specified color (e.g., "red") +
    • [shape]: all regions having the specified shape (e.g., "circle") +
    • [tag]: all regions containing the specified tag (e.g., "source") +
    +Thus, it is possible to act on multiple regions at the same time. + +

    +● Add one or more regions to the regions layer +

    +id = JS9.AddRegions(rarr, opts) +

    +where: +

      +
    • rarr: a shape string, region object or an array of region objects +
    • opts: global values to apply to each created region +
    +returns: +
      +
    • id: id of last region created +
    +The rarr argument can be a region shape ("annulus", "box", +"circle", "ellipse", "point", "polygon", "text"), a single region +object, or an array of region objects. Region objects contain one or +more properties, of which the most important are: +
      +
    • shape: "annulus", "box", "circle", "ellipse", "point", "polygon", "text" [REQUIRED] +
    • x: image x position +
    • y: image y position +
    • lcs: object containing logical x, y and sys (e.g. "physical") +
    • dx: increment from current image x position +
    • dy: increment from current image y position +
    • tags: comma separated list of tag strings +
    • radii: array of radii for annulus region +
    • width: width for box region +
    • height: height for box region +
    • radius: radius value for circle region +
    • r1: x radius for ellipse region (misnomer noted) +
    • r2: y radius for ellipse region (misnomer noted) +
    • pts: array of objects containing x and y positions for polygons +
    • points: array of objects containing x and y offsets from the center for polygons +
    • angle: angle in degrees for box and ellipse regions +
    • color: region color (string name or #rrggbb syntax) +
    • text: text associated with text region +
    +Other available properties include: +
      +
    • fixinplace: if true, region cannot be moved or resized +
    • lockMovementX: region cannot be moved in the x direction +
    • lockMovementY: region cannot be moved in the y direction +
    • lockRotation: region cannot be rotated +
    • lockScalingX: region cannot be resized in the x direction +
    • lockScalingY: region cannot be resized in the y direction +
    • fontFamily: font parameter for text region +
    • fontSize: font parameter for text region +
    • fontStyle: font parameter for text region +
    • fontWeight: font parameter for text region +
    + +

    +● Get information about one or more regions +

    +rarr = JS9.GetRegions(regions) +

    +where: +

      +
    • regions: which regions to retrieve +
    +returns: +
      +
    • rarr: array of region objects +
    +

    +Each returned region object contains the following properties: + +

      +
    • id: numeric region id (assigned by JS9 automatically) +
    • mode: "add", "remove" or "change" +
    • shape: region shape ("annulus", "box", "circle", "ellipse", +"point", "polygon", "text") +
    • tags: comma delimited list of region tags (e.g., "source", "include") +
    • color: region color +
    • x,y: image coordinates of region +
    • radii: array of radii for annulus region +
    • width: width for box region +
    • height: height for box region +
    • radius: radius value for circle region +
    • r1: x radius for ellipse region (misnomer noted) +
    • r2: y radius for ellipse region (misnomer noted) +
    • pts: array of objects containing x and y positions, for polygons +
    • points: array of objects containing x and y offsets from the specified center, for polygons +
    • angle: angle in degrees for box and ellipse regions +
    • wcsstr: region string in wcs coordinates +
    • wcssys: wcs system (e.g. "FK5") +
    • imstr: region string in image or physical coordinates +
    • imsys: image system ("image" or "physical") +
    +The image position can be used to access the image data returned by the +JS9.GetImageData() routine: +
    +    obj = JS9.GetImageData();
+    xreg = JS9.GetRegions("selected")[0];
+    val = obj.data[Math.floor(xreg.y-0.5) * obj.width + Math.floor(xreg.x-0.5)];
+
    +

    +Note the need to integerize the x and y values: JavaScript arrays are +objects and so floating point array indices do not get truncated +automatically as in C. They will return null values. +

    +Also note that since we need 0-based data array indexes, we subtract 1 from +the 1-based image position. But then we must add 0.5 before rounding because +by convention, x.0, y.0 is the middle of the pixel. + +

    +● Change one or more regions +

    +JS9.ChangeRegions(regions, opts) +

    +where: +

      +
    • regions: which regions to change +
    • opts: object containing options to change in each region +
    +Change one or more regions. The opts object can contain the parameters +described in the JS9.AddRegions() section. However, you cannot (yet) +change the shape itself (e.g. from "box" to "circle"). See js9onchange.html +for examples of how to use this routine. + +

    +● Remove one or more regions from the region layer +

    +JS9.RemoveRegions(regions) +

    +where: +

      +
    • regions: which regions to remove +
    + +

    +

    +Working with Shape Layers +
    +

    +

    +JS9 supports individual layers for drawing 2D graphics. The regions +layer is a special case of a shape layer, created automatically by +JS9. The Catalog plugin creates a separate layer for each catalog. +You can define your own shape layer using the NewShapeLayer() +call and then add geometric shapes to it. +

    +Note that the JS9.GetShapes(), JS9.ChangeShapes(), JS9.RemoveShapes() +calls all take a shape specification as the second argument, which can +be any of the following (in order of precedence): +

      +
    • "all": all regions +
    • [id]: a specific region id returned by JS9.AddRegions() +
    • "selected": the selected region (or all regions in the selected group) +
    • [color]: all regions having the specified color (e.g., "red") +
    • [shape]: all regions having the specified shape (e.g., "circle") +
    • [tag]: all regions containing the specified tag (e.g., "source") +
    +Thus, it is possible to act on multiple shapes at the same time. + +

    +● Create a new shape layer +

    +lid = JS9.NewShapeLayer(layer, opts) +

    +where: +

      +
    • layer: name of the layer to create +
    • opts: default options for this layer +
    +returns: +
      +
    • lid: layer id +
    +This routine creates a new named shape layer. You can then, add, change, +and remove shapes in this layer using the routines below. The catalogs +displayed by the Catalog plugin are examples of separate shape layers. +

    +The optional opts parameter allows you to specify default +options for this layer. You can set a default for any property needed +by your shape layer. See JS9.Regions.opts in js9.js for an example of +the default options for the regions layer. + +

    +● Show or hide the specified shape layer +

    +JS9.ShowShapeLayer(layer, mode) +

    +where: +

      +
    • layer: name of layer +
    • mode: true (show layer) or false (hide layer) +
    +Shape layers can be hidden from display. This could be useful, for +example, if you have several catalogs loaded into a display and +want to view one at a time. + +

    +● Add one or more shapes to the specified layer +

    +JS9.AddShapes(layer, sarr, opts) +

    +where: +

      +
    • layer: name of layer +
    • sarr: a shape string, shape object, or an array of shape objects +
    • opts: global values to apply to each created shape +
    +returns: +
      +
    • id: id of last shape created +
    +The sarr argument can be a shape ("annulus", "box", +"circle", "ellipse", "point", "polygon", "text"), a single shape +object, or an array of shape objects. Shape objects contain one or +more properties, of which the most important are: +
      +
    • shape: "annulus", "box", "circle", "ellipse", "point", "polygon", "text" [REQUIRED] +
    • x: image x position +
    • y: image y position +
    • dx: increment from current image x position +
    • dy: increment from current image y position +
    • tags: comma separated list of tag strings +
    • radii: array of radii for annulus shape +
    • width: width for box shape +
    • height: height for box shape +
    • radius: radius value for circle shape +
    • r1: x radius for ellipse shape (misnomer noted) +
    • r2: y radius for ellipse shape (misnomer noted) +
    • pts: array of objects containing x and y positions, for polygons +
    • points: array of objects containing x and y offsets from the specified center, for polygons +
    • angle: angle in degrees for box and ellipse shapes +
    • color: shape color (string name or #rrggbb syntax) +
    • text: text associated with text shape +
    +Other available properties include: +
      +
    • fixinplace: if true, shape cannot be moved or resized +
    • lockMovementX: shape cannot be moved in the x direction +
    • lockMovementY: shape cannot be moved in the y direction +
    • lockRotation: shape cannot be rotated +
    • lockScalingX: shape cannot be resized in the x direction +
    • lockScalingY: shape cannot be resized in the y direction +
    • fontFamily: font parameter for text shape +
    • fontSize: font parameter for text shape +
    • fontStyle: font parameter for text shape +
    • fontWeight: font parameter for text shape +
    + +

    +● Remove one or more shapes from the specified shape layer +

    +JS9.RemoveShapes(layer, shapes) +

    +where: +

      +
    • layer: name of layer +
    • shapes: which shapes to remove +
    + +

    +● Get information about one or more shapes in the specified shape layer +

    +JS9.GetShapes(layer, shapes) +

    +where: +

      +
    • layer: name of layer +
    • shapes: which shapes to retrieve +
    +returns: +
      +
    • sarr: array of shape objects +
    +

    +Each returned shape object contains the following properties: + +

      +
    • id: numeric region id (assigned by JS9 automatically) +
    • mode: "add", "remove", or "change" +
    • shape: region shape ("annulus", "box", "circle", "ellipse", +"point", "polygon", "text") +
    • tags: comma delimited list of region tags (e.g., "source", "include") +
    • color: region color +
    • x,y: image coordinates of region +
    • size: object containing width and height for box region +
    • radius: radius value for circle region +
    • radii: array of radii for annulus region +
    • eradius: object containing x and y radii for ellipse regions +
    • pts: array of objects containing x and y positions, for polygons +
    • angle: angle in degrees for box and ellipse regions +
    + +

    +● Change one or more shapes in the specified layer +

    +JS9.ChangeShapes(layer, shapes, opts) +

    +where: +

      +
    • layer: name of layer +
    • shapes: which shapes to change +
    • opts: object containing options to change in each shape +
    +Change one or more shapes. The opts object can contain the parameters +described in the JS9.AddShapes() section. However, you cannot (yet) +change the shape itself (e.g. from "box" to "circle"). + +

    +

    +Server-side Analysis +
    +

    + +

    +● Run a simple server-side analysis task +

    +JS9.RunAnalysis(aname, parr, func) +

    +where: +

      +
    • aname: name of analysis tool +
    • parr: optional array of macro-expansion options for command line +
    • func: optional routine to call when analysis is completed on server +
    +The JS9.RunAnalysis() routine is used to execute a server-side +analysis task and return the results for further processing within the +Web page. +
  • The optional parr array of parameters is passed to the JS9 +analysis macro expander so that values can be added to the command +line. The array is in jQuery name/value serialized object format, +which is described here: +
    +    http://api.jquery.com/serializeArray/
+
    +
  • func: a function to process the returned data when the task is complete. + +

    +The func() routine is a callback function to process the returned +results from the analysis task. The calling sequence is: +

    +    func(stdout, stderr, aobj)
+
    +where: +
      +
    • stdout: a string containing the standard output from the task +
    • stderr: a string containing the standard error from the task +
    • aobj: the analysis object from the js9Analysis.json file, containing, + among other things, the important rtype: "text" or "plot" +
    +Typically, you would check stderr string first and issue an error +message if there is an error. Otherwise, the stdout string can be +processed based on the return type (rtype) property of the output +(e.g., "text" or "plot"). For plotting, you can use flot +functionality already loaded into JS9, or you can use your own chosen +plotting package. +

    +If no func callback is specified, the default processing will +display "text" in a new light window. If the return type is "plot", +the results are assumed to be in flot format and will be plotted. + +

    +● Run a server-side analysis task utilizing +parameters in a form +

    +JS9.SubmitAnalysis(el, aname, func) +

    +where: +

      +
    • el: form element (unused at present) +
    • aname: name of analysis tool +
    • func: optional routine to call when analysis is completed on server +
    +The JS9.SubmitAnalysis() routine is used to run an analysis +task with input parameters from a form. Typically used as +the Run button action in a form, it automatically serializes +the form values and passes them to the JS9 analysis macro expander so +that these values can be integrated into the analysis command line. +See js9analysis.html for a simple example. +

    +The func callback is the same as for JS9.RunAnalysis() above. + +

    +

    +Miscellaneous +
    +

    + +

    +● Print an image +

    +JS9.Print() +

    +Print the currently displayed image. A new window is displayed +containing the image, along with regions and other graphical layers +(the 2D graphics having been converted to a re-scalable format). The +standard Print dialog box also is displayed and can be used to print +this new window. Dismiss both windows when you are finished. + +

    +● Display help in a light window +

    +JS9.DisplayHelp(name) +

    +where: +

      +
    • name: name of a help file or url of a Web site to display +
    +The help file names are the property names in JS9.helpOpts (e.g., "user" for +the user page, "install" for the install page, etc.). Alternatively, you can +specify an arbitrary URL to display (just because). + +

    +● Get location of JS9 installation directory +

    +rpath = JS9.InstallDir(file) +

    +where: +

      +
    • file: file or directory to convert +
    +returns: +
      +
    • rpath: path of the file relative to the JS9 install directory +
    +Sometimes a plugin needs to load an auxiliary file inside the plugins +sub-directory. The Web page loading the plugin has an arbitrary +location relative to the JS9 install directory, so this routine +returns a relative path to the js9 install directory. + +

    +

    +Prototype Routines (not ready for prime time) +
    +

    +NB: The routines in this section are prototypes and therefore are +subject to change. Feel free to contact us to discuss your needs so +that we can gain a better understanding of is required in these cases. +

    +● Load an auxiliary file +

    +JS9.LoadAuxFile(name, func) +

    +where: +

      +
    • name: class name of auxiliary file to load +
    • func: function to call once the file is loaded +
    +

    It sometimes is desirable to process auxiliary files when an image +is first loaded. Examples include overlaying an image mask on an +image, and pre-loading regions from a region file. +The JS9.LoadAuxFile prototypes this sort of functionality. +

    +Auxiliary files are defined in the js9Prefs.json file by means of the +JS9.auxfiles array containing one or more auxfile objects. Each +auxfile specification has the following properties: +

      +
    • type: type of auxiliary file: currently "mask" or "region" +
    • name: the class name of the auxiliary file +
    • image: image (or template) for which this auxfile is valid +
    • url: URL of the auxfile +
    +For example, the following defines two auxfiles: +
    +  "auxFiles":   [{"type":	     "mask",
+		  "name":	     "sciencemasks",
+		  "image": 	     "casa.*.png",
+		  "url":	     "../myauxfiles/casa-mask.png"},
+		 {"type":	     "regions",
+		  "name":	     "scienceregions",
+		  "image": 	     "casa.*.png",
+		  "url":	     "../myauxfiles/casa.reg"}],
+
    +Here, a mask auxfile and a regions auxfile are defined for Cas-A +dataset(s). These auxfiles are brought into play as follows: +
    +    // run this routine after loading each image
+    function onImageLoad(im){
+      JS9.LoadAuxFile("sciencemasks", function(im, aux){
+        // if we succeed in loading the mask, set up the onchange callback
+        im.onregionschange = regionOnChange;
+        // view the image through the mask data
+        im.maskData = aux.im.raw.data;
+        // I mean now!
+	im.displayImage("all");
+      });
+    JS9.LoadAuxFile("scienceregions");
+  }
+
+  // tell JS9 about the onload callback
+  JS9.imageOpts.onload = onImageLoad;
+
    +An onImageLoad function is defined that will try to load auxfiles of +types "sciencemasks" and "scienceregions". This routine is set to +be called whenever a new image is loaded. +

    +On image load, when JS9.LoadAuxFile() is called, it looks in +the list of known auxfiles for an entry that matches both +the class name and the image name. If found (in the example above, +for Cas-A datasets), the associated auxfile URL is loaded and +type-specific processing is performed: +

      +
    • masks: the mask file is loaded into the Web page as an +off-screen image and an aux object is created as a property of the +image object. This aux object can be used for subsequent processing +(see below). +
    • regions: the regions in the region file are created and +displayed on the image. +
    +Once the initial auxfile processing has been performed, the optional +callback function will be called. For the "mask" example above, the +onregionchange property is set to call a JavaScript function (not +shown here) whenever a region changes. The maskData property is set to +point to the raw data of the auxfile (i.e., aux.im.raw.data). Finally, +the image is redisplayed. Setting the maskData property and +redisplaying the image causes the auxfile's data to be displayed as an +opaque overlay on top of the currently displayed image. +

    +As should be clear from the description above, considerable "black +magic" currently is involved when processing auxiliary files. +Visibility is required into the inner properties of the image +object. Please contact us if you want to work with auxiliary files, so +that we can continue to think about what is required for their support. + +

    +The PNG Representation File +

    The PNG Representation File

    + +

    +X-ray archives present special problems for displaying data. Instead +of images, X-ray data consists of detected photons stored in FITS +binary tables. This means that the file size is related to the number +of detected photons, not the image dimensions. Indeed, X-ray data +files can be hundreds of megabytes in size. Downloading (and then +binning) these tables can be painfully slow, especially if the aim +simply is to offer a quick look at the data. On the other hand, simply +generating a FITS image from the binary table for download breaks the +connection with the original events, which might be needed for +server-side analysis. + +

    +To remedy this situation, JS9 supports use of a special +PNG representation file, explicitly tied to the original event +data. Once downloaded into JS9, the image can be reconstructed +from this file for display. The file maintains information about the +original FITS binary table for use in remote analysis. The idea is +that you create a representation file from the original FITS +binary table and use that file for display in JS9, while supporting +server-side analysis on the original FITS event file. +

    +Display of a representation file is fully integrated into JS9: +

      +
    • The relatively small PNG file is downloaded and read using +standard, optimized browser support. +
    • RGB image values are retrieved using getImageData() into an +off-screen (non-visible) canvas. This is the packed representation of the FITS file. +
    • The FITS header is extracted into a JavaScript object, and actual image dimensions and datatype are determined. +
    • The original image data is unpacked into an HTML5 typed array of the specified data type, with endian conversion applied as necessary. +
    • The standard DS9 algorithm is applied to this array to convert pixel +values to an array of RGB values. +
    • The converted RGB array is sent to the screen using putImageData() +and displayed by the browser. +
    + +

    +Using this representation file, image data values are available to the +client JavaScript code without having to download the much larger +binary table. This means that the contrast/bias conversion can be +performed, image positions/values displayed, etc. using standard +browser capabilities and relatively straight-forward array +manipulation code. Browser-based image plugins can process the image +data, and JS9 can communicate with a back-end server to provide more +sophisticated FITS-based analysis support. + +

    +Note that JS9 is able to distinguish between PNG representation files and +ordinary PNG files and will correctly load either type. + +

    The PNG Representation File

    +

    +The PNG +representation file contains the following information: +

      +
    • fitsfile: the pathname of the FITS file used to generate this PNG +file, including the FITS bracket extension (if present) +
    • fitsheader: a FITS header containing the WCS information +for the generated image +
    • image: a PNG image containing a json version of the FITS header and image data (in its native data type) packed into RGB triplets +
    + +

    Generating the PNG file using tpos and fits2png

    +

    +A PNG representation file can be created either statically or +dynamically at display time as needed. The low-level tpos +program and high-level fits2png script facilitate this conversion: +

    +    tpos [ifits] [opng]
+or
+    fits2png [switches] [ifits] [opng]
+    switches:
+    -abs	# convert relative path to absolute path for storage in PNG
+    -gzip       # assume the file is in gzip format, regardless of its extension
+    -dim	# dimension for PNG image (use to calculate block factor)
+    -js9	# set dim, odir, repl parameters for automatic JS9  conversion
+    -odir	# specify output directory (default: from opng path)
+    -repl	# replace existing PNG? (default: true)
+
    + +

    +The fits2png switches are meant to provide flexibility when running +tpos in batch mode. The fits2png script also is used to generate PNG +files on the fly (i.e., when offering FITS files on your Web page +directly instead of the PNG representation.) + +

    +By default, tpos and fits2png will convert a FITS image or binary +table to a PNG representation file having the same image dimensions: +

    +    tpos m13.fits m13.png
+
    +However, current browsers have a working limit to the image size they +can reasonably handle: 2048x2048 works well; anything larger can be +subject to performance degradation. For maximum flexibility, you can +use Funtools syntax to limit the size of the generated PNG file. For +example: +
    +    tpos 'casa.fits[1024@4027,1024@3944,2]' casa.png
+
    +Here, the PNG file is generated by extracting a 1024x1024 image +centered on a specific point (4027,3994) and then blocking it by a +factor of 2 to create a final 512x512 image. + +

    +For automatic processing with fits2png, specifying the -dims +switch will tell fits2png to calculate the block factor in such a way +as to generate an image of the specified size: +

    +    fits2png -dims 512 512 casa.fits casa.png
+
    +This will block the 8192x8192 Chandra ACIS data by a factor of 16 to +make a 512x512 image centered on the the point (4096,4096). + +

    +In addition to the image, the (generated) FITS image header and the +FITS pathname are stored in the PNG file for use by both the browser +and the server-side helper programs. The image header is used to +provide WCS information for individual pixels as the mouse is moved +across the image. It also is used to provide region information in WCS +format (i.e. independent of block factor). The FITS pathname is used +to locate the original FITS file in order to execute analysis tasks. + +

    +In order to run analysis tasks, the FITS data must be accessible to the +server-side helper program. Therefore, it seems preferable to store +an absolute pathname in the PNG file, but more experience is needed on +this score. You can specify the absolute pathname on the tpos command line, +or else specify the -abs switch on fits2png and it will be determined by the +script. + +

    +If you store a relative path in the PNG file, note that this +path will be utilized by the server-side JS9 helper to locate the FITS +file. This means that if the helper is not started in the same +directory that tpos (fits2png) was run, the relative path will not be +correct. In this case, you can set the JS9.analOpts.dataDir +parameter in the js9Prefs.json file to a path that will be used +instead of the relative path. + +

    +You also must decide where to store the PNG files, e.g. with the FITS +data or in a separate directory. Clearly, this will depend on how your +archive is set up and where you have write access. By default, PNG files +will simply be stored in the path specified on the tpos command +line. You can use the -odir switch on the fits2png script to specify a +generic location: +

    +    tpos ./png ./fits/casa.fits ./png/casa.png    # store in png subdirectory
+    tpos -odir ./png ./fits/casa.fits casa.png    # same
+
    + +

    +The -odir switch can be used to specify a session-based +directory in which to store PNG files. This facility could be used, +for example, in a case where each user has files stored in her or her +own directory, which might be removed at the end of the session. To +facilitate session-based directory specification, a standard HTML cookie +is used to pass the session information between client and server as follows: +

      +
    • When a JS9-enabled page is loaded, a cookie is set containing the +session id in the Web page. For example, one might a set a cookie +whose name is JS9_ID and whose values is 0x1234. +
    • The odir switch is given a directory value containing the cookie +name as part of the string, preceded by a percent sign, %. For +example, odir might be set to ./png/%JS9_ID. +
    • When fits2png is executed, the %cookie name is replaced by the +cookie value. In the example above, the resulting odir value is +./png/0x1234. +
    • The PNG representation file is stored in this odir directory, as usual. +
    +Note that the name of the cookie is arbitrary, but is case sensitive. + +

    +Finally, the special value of @IFILE@ tells fits2png to +store the PNG file in the same directory as the FITS file: +

    +    tpos -odir @IFILE@ .../casa.fits casa.png     # store PNG with FITS file
+
    +Again, these switches are meant to provide initial flexibility while we gain +more experience with community needs. Please let us know how to improve this +part of the system. + +

    +Regardless of where the PNG files are stored, you must adhere to +the W3C "same-origin" security policy, i.e. the PNG data files must be +hosted on the same Web server as the JS9 code. This means that your PNG +files must either be stored in the Web site directory tree, or you +must make a link within the Web site tree to the top level PNG directory. +Also note that Google Chrome's implementation of this policy prevents +you from using JS9 with a +file:// URL. (On Linux and Macs, you can start Chrome with the +--allow-file-access-from-files switch to work around this restriction.) + +

    Loading a PNG File From Your Web Page

    +

    +Once you have generated your PNG files, you can make them available on your +JS9 Web page by creating URLs that call the JS9.Load() routine: +

    +    href='javascript:JS9.Load(filename, opts);'
+
    +where filename is the file to load and +opts is an object containing params to be merged with the +default JS9.imageOpts object. + +

    +For example: +

    +    href='javascript:JS9.Load("png/casa.png", {scale: "log"});'
+
    +Clicking on this URL will cause the casa.png file (here, stored in the +png directory) to be loaded into JS9, using the log scale as a +default. If the JS9 server-side helper is running, it will be alerted +about this new file so that it can run analysis, etc. +

    +See JS9 Public API for complete +documentation about the JS9.Load() routine. + +

    Run-time Conversion of FITS to PNG

    +

    +If you don't generate PNG files beforehand, you can still specify a +FITS file as the first argument to JS9.Load() and have the JS9 +server-side helper run fits2png at run-time.. To do this, you set +the fits2png property in js9Prefs.json: +

    +{
+  "globalOpts": {"fits2png": true ...}
+}
+
    +This tells JS9 to convert FITS files instead of downloading them +directly. Then you can use JS9.Load() as usual: +
    +    href='javascript:JS9.Load("fits/3c58.fits");'
+
    +The default command for this conversion is contained in the js9Helper.js file: +
    +    fits2png -js9 -odir ./png
+
    +The -js9 switch will calculate a block factor to generate a 512x512 +PNG image. It will not replace an existing PNG file, if it +exists. Note that the output directory is set explicitly to be the png +subdirectory of the sample installation. You can change this command +to suite your site needs. + +

    +Server-side Analysis Tasks + +

    Adding Server-side Analysis Tasks to JS9

    + +

    +A JS9 Web site can define analysis tools that will be loaded into the +user's JS9 Analysis menu. These analysis tasks are then +executed by the back-end (CGI or node.js) server using the original +FITS data, with results sent back to the browser for display. + +

    To learn how to install the back-end helper, see: +Installing a Server-side Helper. + +

    +Analysis tools are defined within files contained in the +analysis-plugins directory. If a file in this directory +ends with a ".json" extension, it is assumed to be an analysis +definition file. The following sample analysis definition files will +be found in the analysis-plugins directory by default: +

      +
    • fits2png.json: the command line for converting FITS to PNG files +
    • js9Analysis-fits.json: generic FITS tasks (e.g. display header) +
    • js9Analysis-funtools.json: funtools-based analysis tasks +
    +If you plan to allow dynamic conversion of FITS files to PNG +representation files, the fits2png.json file should be left in +the plugin directory. The other two are optional and should be removed +if funtools is not available. + +

    +Analysis definition files are in JSON format +(http://www.json.org/) and consist of an array of JavaScript objects, +one for each analysis tool. The properties which define an analysis +tool are: +

      +
    • name: a short identifier string (typically one word) +
    • title: a longer string that will be displayed in the Analysis menu +
    • files: a rule that a filename will be matched against to determine +whether this task is available for the current image (not yet implemented) +
    • purl: a URL pointing to a Web page containing a user parameter form +
    • action: The command to execute on the server side +
    • rtype: a return type, which can be text or plot +
    • hidden: if true, the analysis task is not shown in the Analysis menu +
    +See the sample json files in the analysis-plugins directory for the +JSON syntax of this file. + +

    +The action string contains the command to execute. For security +reasons, this action is never executed directly. Instead, the first +argument of the command must be a wrapper script contained in +the analysis-wrappers directory. The js9Xeq wrapper +script contained therein is the default script for running JS9 +analysis. The second argument in the action string is a command id, +which is executed within the command-processing case statement of +the js9Xeq. This wrapper script checks for valid commands and +arguments, and then executes the specified command in a way that +protects against malicious attack. You can modify this script to meet +your needs by adding case statements for each of the new tasks you +want to run. + +

    +Alternatively, you can run your analysis tasks through your own +wrapper script, by placing it in the analysis-wrappers +directory. Using your own wrapper script allows you to perform your +own special setup (e.g., setting environment variables, cd to work +directory) before executing a task. Obviously you can +use js9Xeq as an example and modify it to suit your needs. + +

    +In either case, note that execution of a wrapper script is +accomplished by pre-pending the path of the analysis wrapper directory +to the wrapper script name and executing that full pathname directly. +This prevents a would-be attacker from executing anything except the +wrapper itself. Of course, you still have to be careful to avoid +insecure shell coding in your wrapper script. +See The World +Wide Web Security FAQ for advice on writing CGI scripts. + +Note that JS9 scripts generally use bash or sh. Please make sure your +bash and sh programs are properly patched to protect against the bash +bug (CVE-2014-6271). + +

    +The action command line can contain macros (strings prefixed +with the $ character) that will be expanded by the browser before +the action is sent to the server for processing. Typically, these macros are +used to specify filenames, regions, and (possibly) user parameters. The +following intrinsic macros are defined: +

      +
    • $filename: pathname of the original FITS file +
    • $regions: all currently defined regions +
    • $sregions: all source regions +
    • $bregions: all background regions +
    +For example, to run the funcnts program, specifying the original FITS +file as well as source and background regions, use: +
    +    funcnts $filename $sregions $bregions
+
    + +

    +Many analysis tasks do not require the user to select additional parameter +options and can can be executed immediately. Other command require +user-selected options. These latter options should be put into a Web +form, whose location is specified by the purl option. See +the params/histplot.html file for an example. + +

    +Parameter options in a parameter form should have unique ids. These +ids can then be added as macros to the action command line by +prefixing them with a $. For example, the histplot command is: +

    +    js9Xeq histplot '$filename[$regions]' '$norm $bwidth' $column $bins
+
    +Here, the norm, bwidth, column, and bins +parameters are taken from the Web form for histplot. The $filename +and $regions macros are intrinsic to JS9. + +

    +The input element of the analysis form should run +the JS9.SubmitAnalysis() command, which will serialize the form, +pass it to the macro expander, and then send the resulting command string +to the server for execution. See histplot.html for sample syntax. + +

    +The rtype property determine how JS9 handles return values: +

      +
    • text: the returned text is displayed in a lightweight window +
    • plot: the returned plot data is plotted using the jQuery +flot widget (see http://www.flotcharts.org/) +
    +Sample scripts such as funcnts2flot and funhist2plot +generate a JSON string that contains a valid flot object. For +example, the radial profile plot contains x, y, and error values: +
    +{
+  "color": "green", 
+  "label" : "surf_bri(...) vs. avg_radius(...)", 
+  "points" : {"errorbars" : "y", 
+              "yerr" : {"show" : "true", "color" : "red"}},
+  "data": [[x1, y1, e1], [x2, y2, e2], ... [xn, xn, en]]
+}
+
    +while the histogram plot contains only x and y values: +
    +{
+  "color": "blue", 
+  "label" : "counts vs. ...bin", 
+  "data": [[x1, y1], [x2, y2], ... [xn, xn]]
+}
+
    +If your analysis task generates one of these two plot formats, JS9 +will display the plot data. Plotting is still somewhat experimental +and rudimentary. We will be adding features with time (e.g. ability to +change scales between linear and log). Please work with us to improve +plotting support. + +

    +Finally, the hidden value determines whether or not a task is +displayed in the Analysis menu. If hidden value is true, the +analysis task is not shown. However, it still is available to the +JS9.RunAnalysis() routine. The fits2png command in the +fits2png.json definition file is an example of a hidden +command: it is run indirectly by JS9 and need not be listed as a user +task. + +

    +

    Adding Analysis Tasks Directly to Your Web Page

    +

    +By default, server-side JS9 analysis tasks are executed using +the Analysis menu, but they also can be executed directly from +the Web page by means of HTML elements (buttons, forms, etc.) To do +this, a Web page author simply creates the desired interface and calls +either JS9.RunAnalysis() (for buttons, menus, etc.) +or JS9.SubmitAnalysis() (for forms). These are described +below. See the js9analysis.html page for an example. + +

    +The JS9.RunAnalysis() routine is used to execute an analysis task and +return the results for further processing within the Web page. The +JS9.SubmitAnalysis() routine works similarly, but it is used +with a form: it automatically serializes the form values and passes +them to the analysis macro expander so that these values can be put +into the analysis command line. The calling sequences for these +routines are similar: +

    +    JS9.RunAnalysis(aname, [options], returnFunc);
+    JS9.SubmitAnalysis(this, aname, returnFunc);
+
    +where: +
      +
    • aname: the name value of the task (as defined in the js9Analysis.json file) +
    • options: an optional array of parameters to pass to the analysis +macro expander. The array is in jQuery name/value serialized object +format, which is described here: +
      +    http://api.jquery.com/serializeArray/
+
      +
    • returnFunc: a function to process the returned data when the task is +completed +
    • this: the 'this' value of the form element +
    +

    +The returnFunc() routine is a callback function to process the returned +data from the analysis task. The calling sequence is: +

    +    returnFunc(stdout, stderr, aobj)
+
    +where: +
      +
    • stdout: a string containing the standard output from the task +
    • stderr: a string containing the standard error from the task +
    • aobj: the analysis object from the js9Analysis.json file, containing + the rtype (e.g. "text" or "plot") property +
    +Typically, you would check the stderr string first and issue an error +message if there is an error. Otherwise, the stdout string can be +processed based on the return type (rtype) of output (e.g., "text" or +"plot"). For plotting, you can use the flot functionality that +is loaded into JS9, or you can use your own chosen plotting +package. See js9analysis.html for a simple example. + +

    JS9: image display right in your browser

    +Eric Mandel, John Roll, Alexey Vikhlinin +

    +Cambridge, MA 02138 +
    + +

    +

    Introduction to JS9

    +

    +JS9 is a JavaScript version of the de facto standard DS9 image display +program. It allows you to view and manipulate astronomical image data +in your browser. +

    +Please choose from the following topics: +

    + +

    +

    Getting Started with JS9

    +

    +JS9 provides astronomical image display capabilities right in your browser. +JS9 takes both its name and its core functionality from the de facto standard +DS9 image display program for desktop use, which is available at: +

    +    http://ds9.si.edu
+
    +The JS9 display consists of one or more components that can be added +to a Web page by the Web page designer. At a minimum, the JS9 display +will contain an image display canvas. It usually also will display a +menu strip containing several pull-down menus. Traditionally, this +menu strip is placed on top of the image canvas, but Web designers +have complete control over its placement. JS9 also can display an info +box, a command-line window, a pan window, a zoom window, as well as +other plugins. All of these windows can be brought up dynamically from +the View menu. + +

    +Astronomical image data usually is offered on a JS9 Web page as one or more +clickable URLs. When you click on a data URL, it is displayed on the JS9 image +canvas. Multiple images can be loaded into a single JS9 display. The File +menu allows you to switch between these images. + +

    +Once an image is loaded, you can move the mouse (or a single finger on +a touch screen) to display position and pixel value +information. Pressing the left mouse button and moving the mouse (or +using two fingers on a touch screen) will change the contrast/bias of +the displayed image, bringing image features into relief. + +

    +Menu options allow you to change the scaling algorithm and/or color +map, add geometric regions of interest, change world coordinate system +(WCS) parameters, and run site-specific astronomical analysis tasks on +the original FITS data. + +

    +

    JS9 Menus

    +

    +The following menus are in the default JS9 menu bar. Note that Web +designers have control over which menus are displayed (or even whether +the menu bar itself is displayed). Thus, not all of the menus listed below +will be found on all Web pages: +

      + +

    • File: The File menu displays a list of all images +currently loaded into this instance of JS9. The displayed image is +marked with a star burst. To display a different image, simply choose +it in the menu. The menu contains an open ... options which +displays a file browser for loading FITS files (compressed or +uncompressed). It also contains options to: +

        +
      • print ... to print the current image display window +
      • display FITS header for the current image +
      • display pageID, a unique ID that can be used when +communicating with JS9 externally +
      • close image to close the image and release browser resources +
      + +

    • View: The display value/position option specifies whether +image position and image pixel value is displayed as the mouse (or +finger) moves over the image. By default, this information is +displayed in the upper left of the image. You can redirect the display +to a movable, light-weight window by choosing the InfoBox menu +option. The Console menu option will bring up a movable, light-weight +console window into which JS9 commands can be entered. +The Magnifier menu option will bring up a movable, +light-weight window showing a blocked image of the data in an area +surrounding the mouse as it moves. The default magnification of four +can be changed using command buttons on the magnifier window. +The Panner menu option will bring up a movable, +light-weight panner window that displays the full image along with a +viewport rectangle showing the currently displayed image section in +the primary image window. The viewport can be moved around in order to pan +to different locations in the primary image. The panner also has +command button options to zoom the viewport itself. (This makes +the viewport rectangle larger at the expense of displaying only a +section of the full image. It is useful for panning in a very large +image.) +

      +In addition to these core options, the View menu also lists the +currently loaded View Plugins. JS9 itself supplies the following plugins: +

        +
      • Archive and Catalogs: allows you to display image data retrieved +from various archives and overlay catalog information +
      • Binning: supports binning and column filtering on FITS binary tables +
      • Pixel Table: displays an array of pixel values around the current mouse position +
      +

      +Web developers can develop and register other plugins (which generally are +loaded into either the View or Analysis menus). + +

    • Zoom: The zoomIn and zoomOut menu options +zoom the primary image in or out by a factor of +two. The zoomToFit options calculates a zoom factor that fits +the entire image into the JS9 display. You also can set the zoom +factor to a pre-specified value using menu options. You can specify +any floating point zoom factor in the numeric zoom value text +box. The pan to center option pans to the center of the image, while +the reset zoom/pan sets the zoom to 1 and centers the display. + +

    • Scale:Each scale option specifies a different scaling +algorithm to use when converting image pixel values to RGB +values. (The procedure for doing this conversion is detailed in the +DS9 documentation titled "How It Works".) The log scale, for example, +is especially useful with X-ray data. The current scale is marked +with a star burst. + +

      +You also can change the low and high values used to clip the image +data before scaling by changing the low value for clipping +and/or high value for clipping numbers. These values are set +initially with the data's min and max values or the z1,z2 values +calculated by the IRAF zscale algorithm (depending on the value +of the Web site's JS9.imageOpts.scaleclipping parameter. The +default usually is "dataminmax".). Finally, you can set (or reset) the +low and high values to data min,max or zscale z1,z2 using the set +vals to data min/max or set vals to zscale z1/z2 options, +respectively. (Note that zscale requires a considerable amount of +memory and does not work on very large images. We will try to remove +this restriction in the future.) + +

    • Colormap: Each colormap option specifies a different +distribution of RGB values to use when converting image pixel values to RGB. +(The procedure for doing this conversion is detailed in the +DS9 documentation titled "How It Works".) Choose the colormap you like best, +or try different ones to see how data features can be brought to the fore +by color and contrast/bias. + +

      +You can enter a floating point value into the contrast value and +bias value text boxes to set the contrast/bias. Note that the +contrast value ranges from 0 to 10 and the bias ranges from 0 to 1 +(following DS9 conventions). + +

      +The reset contrast/bias option restores the original +contrast/bias value (which is especially useful if you changed the +contrast/bias or scale and now can't see any features at all!) + +

      +The invert cmap option inverts the colormap (e.g. in the gray map, +this will change white to black and vice versa). + +

      +If you have three images of the same size, scale, and pointing +direction (e.g. three energy cuts of a Chandra data set), you can +display each one separately and assign to them one of the red, +green, or blue colormaps. If you then select the RGB mode +menu option, they will be displayed as one RGB composite image. The +current image (as shown in the File menu) determines which of +the three independent colormaps is changed by the contrast/bias +manipulation. To remove an image from the RGB composite, give it a +different colormap. Re-join (or add a new image) by assigning one of +the RGB colormaps. Simply turn off RGB mode to display the images +separately. + +

    • Region: Choose the appropriate menu option to create a +region of type annulus, box, circle, ellipse, +point, polygon, text. +(see below for details on how to use regions). One or more regions can +be created and manipulated on a single image. + +

      +The listRegions menu option will display all regions. +The listOnChange menu option will cause all regions to be listed +whenever one changes.The deleteRegions menu option will delete +all regions. Note that each individual region has a configuration +menu (double-click inside the region) that supports +these options for that region only. + +

    • WCS: Use this menu option to select a world coordinate +system when displaying pixel positions and regions (assuming +the data file supports WCS). Available systems are: FK4, FK5, +ICRS, galactic, or ecliptic. The native +option chooses the system stored in the data file. The image +and physical systems will display only image coordinates (not +WCS coordinates). Physical coordinates are tied to the original +(block 1) file coordinates while image coordinates are tied to +the current image data being displayed. Server-side X-ray analysis +routines operating on the original file generally want physical coords +rather than image coords. Browser-based plugin routines generally use +image coordinates to operate on the in-memory image data. + +

      +You also can choose the units in which WCS information is displayed: +degrees, radians, or sexagesimal. Image and +physical coordinates are displayed in units of pixels. + +

    • Analysis: Each JS9 site can define server-side analysis +tasks to be run from the Analysis menu. Tasks are of two types: +

        +
      • immediate tasks: These tasks are executed directly and +immediately from the Analysis menu. No parameter setup is needed. +
      • parameter tasks: These tasks bring up a lightweight +parameter window allowing various parameters to be set before +executing the task. Parameter tasks are identified by the presence of +an ellipsis (...) after the task name. +
      +

      +For example, the sample implementation of JS9 offers the following tasks: +

        +
      • Counts in Regions: Run the funcnts program on the specified +source and background regions and return a text display (immediate task). +
      • Radial Profile: Run the funcnts program on the specified +source and background regions and return a plot display. The source regions +consist of circles or annuli (immediate task). +
      • Energy Plot: Create a histogram of the pi column of a +binary table and return a plot display (immediate task). The pi column +must exist in the data file (e.g., Chandra ACIS data but not Chandra +HRC data). +
      • Histogram Plot: Create a histogram of the user-specified +column of a binary table and return a plot display (parameter +task). Parameters include: histogram column name, number of bins, use +bin width instead of bin size, and an option to normalize by bin +width. A help file is appended to the parameter display. +
      + +

      +In addition to server-side analysis, the Analysis menu lists +the currently loaded Analysis Plugins. JS9 itself supplies the +Imexam plugin, which offers the following tasks: +

        +
      • Encircled Energy +
      • Radial Proj +
      • Histogram +
      • Region Stats +
      • X Proj +
      • Y Proj +
      • 3dPlot +
      +

      +Finally the set data path ... option allows you to specify a +colon-separated list of directories for JS9 to search when looking for +FITS data files that have been dropped onto the display. This is used +by JS9 when performing server-side data analysis on local +drag-and-drop FITS files. It is necessary to specify data paths +explicitly since Web pages are not allowed to determine the pathname +of such files automatically (for obvious security reasons). + +

    • Help: Show this and other JS9 help pages. The Help menu +also contains help for Plugins, including the Imexam plugins +listed above. +

    + +

    +

    JS9 Mouse Interaction

    +

    +In keeping with the needs of mobile devices, JS9 utilizes a single +mouse button for user interaction. Keyboard input also is minimized. +Moving the mouse (or a single finger on a tablet) over the image will +display the position/value of individual pixels. Pressing and moving +the mouse (or two fingers) will change the contrast and bias of the +image. A double-click (or double-tap) inside a region will bring up +the configuration menu for that region. + +

    +

    JS9 Regions

    +

    +Regions are geometric shapes that can be used to mark part of an image +for analysis. JS9 allows you to create the following region +types: annulus, box, circle, ellipse, point, polygon. +A text region also can be created to annotate an image. When one +of these options is selected, the region is created in the center of +the image. It then can be dragged to the desired location. Arrow keys +also will move the region one screen pixel in the specified direction. +A selected region can be deleted by pressing the Delete key (where +available. On a tablet, use the delete option in the configuration menu). +

    +Click inside a region to select it and display the resize/rotate +controls around its perimeter. Grabbing a handle allows the size of +the region to be adjusted or rotated. In the case of the box and +ellipse regions, the width and height are controlled separately. Click +outside the region to de-select (or click another region to select +that one). + +

    +A double-click inside a region brings up a configuration menu. You can +change various values associated with a region by entering new values +in the appropriate text boxes and the clicking Apply. + +

    +The configuration menu has the following standard options: +

      +
    • id: the id of this region, which can be used programmatically to select it for processing (read-only) +
    • type: the type of region (read-only) +
    • image center: new image pixel values can be entered to change the region position +
    • WCS center: new WCS position values can be entered to change the region position (where WCS is available) +
    • Tags: the default tags (source, background, include, exclude) +are used in X-ray astronomy but you can enter any string to tag this region and then select programmatically using tags +
    • WCS Region: the WCS representation of this region, where applicable (read-only) +
    • Image Region: the image representation of this region, where applicable (read-only) +
    • Options: +
        +
      • List On Change: list this region when it's moved or resized +
      • Fix in Place: disable move and resize capability +
      • Delete: delete this region. On an iPad, this currently is +the only way to delete a region. +
      +
    +

    +In addition, regions of different type support specific configuration +parameters in this menu. +
    +The annulus region supports: +

      +
    • Radii: change the radii of the region (in pixels) +
    +The box region supports: +
      +
    • Width: change the width of the region (in pixels) +
    • Height: change the height of the region (in pixels) +
    • Angle: change the angle of the region (in degrees, counter-clockwise) +
    +The circle region supports: +
      +
    • Radius: change the radius of the region (in pixels) +
    +The ellipse region supports: +
      +
    • Radii: change the r1 and r2 radii of the region (in pixels) +
    • Angle: change the angle of the region (in degrees, counter-clockwise) +
    +The polygon region supports: +
      +
    • Points: change the image points of the region (in pixels) +
    • Angle: change the angle of the region (in degrees, counter-clockwise) +
    +The text region supports: +
      +
    • Text: change the text of the region +
    • Angle: change the angle of the region (in degrees, counter-clockwise) +
    + +

    +

    Meta Key Accelerator

    +

    +The meta key is the Command key on a Mac and the Control +key everywhere else. + +

    +When a keyboard is available, pressing the meta key while +clicking in the primary image window will pan the image so that the +clicked location is in the center of the display. + +

    +The meta key also disables execution of plugin callbacks on +all mouse events. See Local Tasks for +more information about plugins and browser-based analysis. + +

    +Within a polygon, if you press meta and click the mouse on the +polygon border, a new point will be added at that point. If you press +the meta key and click on an existing point, it will be deleted. + +

    +

    Drag and Drop FITS Images

    +

    +You can drag and drop FITS images and binary tables onto JS9 to +display the image data. All browser-based functions (scaling, +colormap, pan, zoom, regions, WCS) should work as expected. You can +run server-side analysis tasks on these data files if the back-end +server is on your local host machine. In this case, you must set your +DataPath variable in the Analysis menu to help JS9 locate the original +data file. + +

    Creating a JS9 Web Page

    + +

    Adding JS9 to Your Web Page

    +

    +The sample js9basics.html file shows how to add JS9 to a Web page by +assigning JS9 CSS classes to "div" elements. The js9multi.html Web +page goes further by showing how multiple instances of JS9 can be +added to a Web page using unique IDs. + +

    +To start, a few JavaScript and CSS files must be loaded into the Web +page. Ordinarily this is done in the page's header, which typically +will look something like this: +

    +  
+  <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
+  <meta http-equiv="X-UA-Compatible" content="IE=Edge;chrome=1" > 
+  <link type="image/x-icon" rel="shortcut icon" href="./favicon.ico">
+  <link type="text/css" rel="stylesheet" href="js9support.css">
+  <link type="text/css" rel="stylesheet" href="js9.css">
+  <script type="text/javascript" src="js9support.min.js"></script>
+  <script type="text/javascript" src="fitsy.min.js"></script>
+  <script type="text/javascript" src="js9.min.js"></script>
+  <script type="text/javascript" src="js9plugins.js"></script>
+  </head>
+
    +Order is important: you must load js9support.min.js before you load +js9.min.js. You must load the plugin files after you load js9.min.js. +You can simply copy the order of files as specified in the JS9 demo files. + +

    +The text file js9support.txt is a list of the files contained +in js9support.css, js9support.js, js9support.min,js, and +js9plugins.js. Note that jquery v1.11.1 is one of the files loaded by +js9support.js. All of these files are contained in the js and css +sub-directories. + +

    +The fitsy.js and js9.js files (or their minified counterparts) +are loaded separately so that we can offer easy updates. as needed. +Fitsy.js contains basic FITS support and js9.js is the core JS9 module. + +

    +Instances of JS9 are placed on a Web page by assigning JS9 classes +to ordinary "div" elements. The two important JS9 classes are: +

      +
    • JS9: this class will display the main JS9 image window +
    • JS9Menubar: this class will display the JS9 menu bar +
    + +

    +You also can use these classes: +

      +
    • JS9Console: this class will display a console window for executing +typed commands (very retro, but often quite useful!) +
    • JS9Info: this class will display position, value, and +region information (patterned after DS9's display window). It's nicer +and more complete than the default display in the upper left of the +image, but takes up more screen real estate. +
    • JS9Magnifier: this class will display the magnifier window +
    • JS9Panner: this class will display panner window +
    +

    +NB: all of these secondary windows can be displayed as light windows +using the appropriate View menu options. Light windows can +moved around on the page. Also note that if a window is declared +statically in a page, it will not be made available in the View +menu. + +

    +Placement of JS9 div elements should follow standard Web page rules +and constraints. This means that div elements can be placed in any +order to create different graphical views. For example, the +js9basics.html page places the menubar above the image display, in +keeping with the traditional layout of DS9. The entire JS9 construct +is placed in a data cell of a table, next to a data cell containing +data URLs. + +

    +Multiple instances of JS9 can be added to a single Web page. This is done by +giving each JS9 div element a unique ID. In order to tie otherwise separate +JS9 components together, the IDs should be specified as follows: +

      +
    • start with a unique ID name, e.g. "myJS9". +
    • follow with an optional dash or underscore (not needed for the main window) +
    • finish with the type of JS9 element: +"Menubar", "Panner", "Magnifier" "Info", or "Console" +
    + +

    An example of how to define multiple instances of JS9 is found in +the js9multi.html file. Two DS9 instances are defined, having IDs of +"JS9" (the default) and "myJS9". When "myJS9" is the display ID, +"myJS9-Menubar" specifies the associated menu bar and "myJS9Console" +specifies the associated console. + +

    +The ID is not required if there is only one JS9 instance on the page, +since it defaults to "JS9". However, if your site needs to communicate +with clients using the js9 script for external communication, +you can differentiate between clients loading the same JS9-enabled Web +page by supplying a unique ID when the JS9 page is served. + +

    +The js9.css file contains CSS directives for various parts of +JS9. These can be modified (or overwritten) as needed, subject to +ordinary CSS rules. In general, we recommend overwriting CSS rules by +loading a site-specific CSS file after the js9.css file. This makes +updating much easier. + +

    +

    Adding Server-side Analysis Tasks to Your Web Page

    + +

    +Server-side JS9 analysis tasks can be executed using +the Analysis menu, but they also can be executed directly from +the Web page using HTML elements (buttons, forms, etc.) To do this, a +Web page author simply creates the Web interface and calls +either JS9.RunAnalysis() (for buttons, menus, etc.) +or JS9.SubmitAnalysis() (for forms). These are described +in the Local Tasks web page. + +

    +

    Adding Local Analysis Tasks to Your Web Page

    + +

    +JS9 also supports the ability to perform local analysis, i.e., +analysis tasks defined and executed right on your Web page, rather +than being executed by a back-end server. This is accomplished by +offering access to the image data and region information via +a public JS9 API. See the +Local Tasks for more information. + +

    +

    Adding JS9 Display Windows Dynamically

    +

    +JS9 display windows can be created dynamically using the JS9 Public API call +JS9.LoadWindow(). You can create a light window to hold a new +JS9 display on the same page or you can create an entirely separate +pop-up window. See the +JS9 Public API for more information. + +

    +

    Adding Data Files to a Web page

    +

    +Data files are added to a Web page by supplying URLs that call +the JS9.Load() routine. See: +Adding Data Files To a Web Page for more +information. + +

    +Displaying Your Data + +

    Displaying Your Data With JS9

    + +

    Loading a FITS File From Your Web Page

    +

    +Once you have your Web page set up, you can make your FITS data files +available on your JS9 Web page by creating URLs that call +the JS9.Load() routine: +

    +    href='javascript:JS9.Load(filename, opts);'
+
    +where opts can be: +
      +
    • filename is the path relative to the current Web page location +
    • imageOpts: an object containing params to be merged with the +default JS9.imageOpts object +
    +

    +For example: +

    +    href='javascript:JS9.Load("fits/casa.fits");'
+
    +Clicking on this URL will load the casa.fits file (here, stored in the +fits directory directly beneath the Web page location). If the JS9 +server-side helper is running, it will be alerted about this new file +so that it can run analysis, etc. +

    +To override default image parameters, specify imgOpts parameters as the second argument: +

    +    href='javascript:JS9.Load("fits/m13.fits", {scale:"linear", colormap:"sls"});'
+
    +

    +To load an image into a specified display, pass the display id in an object as +the last argument in the call. This can be the second or third argument, +depending whether the image object also is passed: +

    +    # the display object can be passed as the second argument ...
+    href='javascript:JS9.Load("fits/casa.fits", {display: "myJS9"});'
+    # but when image opts is also passed, it's the third argument  
+    href='javascript:JS9.Load("fits/3c273.fits", {scale: "linear"}, {display: "myJS9"});'
+
    +

    + +

    Pre-Loading a File From Your Web Page

    +

    +You can pre-load one or more data files into JS9 when the Web page +itself is loaded by adding the JS9.Preload() routine to +the onload event in your Web page body element: +

    +<body onload="JS9.Preload('fits/casa.fits', 
+		          'fits/snr.fits', {colormap:'heat'},
+		          'fits/3c58.fits',
+		          'fits/m13.fits', {scale:'linear', colormap:'sls'},
+		          'fits/3c273.fits',
+		          'fits/ngc1316.fits', {scale:'linear'},
+		          'fits/ngkper.fits', {colormap:'grey'});">
+
    +Note that this routine takes a list of images, each of which +optionally can have an associated imgOpts argument. The display +opts can be passed as the final argument and will apply to all images. + +

    JS9: image display right in your browser

    + + + + + +
    +
    +
    + +
    + Questions? Please contact + + Eric Mandel + +
    +     +     		+
    + +
    + +
    +
    + JS9 is our Web-based implementation of DS9: +
      +
    • display URL-based FITS images and binary tables +
    • drag and drop FITS images and binary tables +
    • change the colormap and scale +
    • manipulate the contrast/bias with the mouse +
    • display pixel values and WCS position information +
    • create and manipulate geometric regions of interest +
    • add your own extensions using plugins and the Public API +
    • perform data analysis (local and server-side) +
    • display RGB composite images +
    • control JS9 from the command line +
    • print images +
    +

    + JS9 can change how we think about image display and analysis, + moving beyond the Desktop into the Web. You can simply drag and + drop a FITS image from your computer onto this JS9 display. All + of basic JS9 functionality is immediately available: zoom, pan, + colormaps, scaling, regions, WCS, analysis ... +

    + You can extend JS9 using the plugin facility in combination + with the JS9 Public API. For example, you can perform + browser-based analysis on the displayed image. Click the + Plugins tab, create a region, and move it around ... +

    + In addition, data files loaded from the server support + server-side analysis (using the original data files on the + back-end server). Server-side analysis can be run, for example, + in response to region changes, with the results displayed back + in your browser. For the Cas-A X-ray image currently being + displayed, click the Analysis tab, choose a task, create a + region, and move it around ... +

    +

    +
    +
    + Energy Spectrum + Counts in Regions + Radial Profile +
    +
    +
    + A quick introduction to JS9, regions, and server-side data analysis: +
      +
    • Press the mouse in the image and move around to change the contrast and bias (to bring out features). +

      +

    • Create one or more regions using the JS9 Region menu. +
    • Pres the mouse inside a region and drag it to the + desired location. +
    • Resize or rotate the region by clicking to + select it, and then moving one of the handles. +
    • Temporarily group regions by pressing the meta key + and using mouse selection. You then can + move/resize/rotate them together. +

      +

    • Choose an analysis to run on the back-end server: +
        +
      • Energy Spectrum plots a histogram of the energy + value of photons in the region(s). +
      • Counts in Regions presents a text display of the + number of photons found in the region(s). +
      • Radial Profile plots the number of photons in each + region of an annulus. +
      +
    • As you move or resize, the task will run and + results will be displayed here. +
    • The region context menu has lots of region options. +
    • These tasks also can be run from the JS9 Analysis menu. +
    + See the Plugins tab for a demo of browser-based analysis. +
    +
    +
    +
    +
    +

    + JS9 plugins allow you to perform browser-based analysis: create a + region and move it around ... +

    + + + + + +
    +

    + See the Local Analysis Tasks help page for info about plugins. +

    +

    +
    + + +
    + Release 1.0 marks the first official public release of + JS9. The core system (images, regions, pan, zoom, scaling, + local plugins, remote analysis) has benefited from more than a + year of beta testing . The Public API is stable and will provide + a solid basis for community-driven extensions. We believe that + JS9 is ready to serve the evolving needs of the astronomical + community. +

    + JS9 work on browsers that support the HTML5 canvas element. It + has been tested on the following browsers: +

      +
    • Firefox 18+ +
    • Chrome +
    • Safari (including the iPad) +
    • IE9 (IE8 doesn't support the HTML5 canvas element) +
    + JS9 is powered by the following technologies, to whom grateful acknowledgment is made: +
      +
    • emscripten for C-to-JavaScript (https://github.com/kripken/emscripten) +
    • dynamic drive for light windows (http://www.dynamicdrive.com/dynamicindex8/dhtmlwindow/index.htm) +
    • fabric.js for regions and other 2D graphics (http://fabricjs.com/) +
    • flot for internal plotting (http://www.flotcharts.org/) +
    • HTML5 for image display and most everything +
    • jquery for programming ease (http://jquery.com/) +
    • jquery.contextMenu for menus (http://medialize.github.io/jQuery-contextMenu/) +
    +

    + JS9 is distributed under the terms of The MIT License. +

    + If you have questions or comments, please contact:
    + Eric Mandel, Harvard-Smithsonian Center for Astrophysics +

    +
    + The JS9 source tar file is available below. This + will suffice to display FITS images via drag-and-drop, and to + utilize browser-based plugins. +

    + If you want the JS9 demo pages to work at your site, you will + need to download the JS9 data tar file. +

    + If you want to configure a back-end helper (for server-side analysis + and creation of png representation files), you will need to + download the funtools tar file. +
    +

    +

    + JS9 also is available on github: +
    +

    + We look forward to your pull requests ... +

    + Development of JS9 at the + Harvard-Smithsonian Center for Astrophysics + is supported by + Smithsonian Institution + and the + Chandra X-ray Science Center. +

IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO + NOT CONTROL. + + + This file creates a global JSON object containing two methods: stringify + and parse. + + JSON.stringify(value, replacer, space) + value any JavaScript value, usually an object or array. + + replacer an optional parameter that determines how object + values are stringified for objects. It can be a + function or an array of strings. + + space an optional parameter that specifies the indentation + of nested structures. If it is omitted, the text will + be packed without extra whitespace. If it is a number, + it will specify the number of spaces to indent at each + level. If it is a string (such as '\t' or ' '), + it contains the characters used to indent at each level. + + This method produces a JSON text from a JavaScript value. + + When an object value is found, if the object contains a toJSON + method, its toJSON method will be called and the result will be + stringified. A toJSON method does not serialize: it returns the + value represented by the name/value pair that should be serialized, + or undefined if nothing should be serialized. The toJSON method + will be passed the key associated with the value, and this will be + bound to the value + + For example, this would serialize Dates as ISO strings. + + Date.prototype.toJSON = function (key) { + function f(n) { + // Format integers to have at least two digits. + return n < 10 ? '0' + n : n; + } + + return this.getUTCFullYear() + '-' + + f(this.getUTCMonth() + 1) + '-' + + f(this.getUTCDate()) + 'T' + + f(this.getUTCHours()) + ':' + + f(this.getUTCMinutes()) + ':' + + f(this.getUTCSeconds()) + 'Z'; + }; + + You can provide an optional replacer method. It will be passed the + key and value of each member, with this bound to the containing + object. The value that is returned from your method will be + serialized. If your method returns undefined, then the member will + be excluded from the serialization. + + If the replacer parameter is an array of strings, then it will be + used to select the members to be serialized. It filters the results + such that only members with keys listed in the replacer array are + stringified. + + Values that do not have JSON representations, such as undefined or + functions, will not be serialized. Such values in objects will be + dropped; in arrays they will be replaced with null. You can use + a replacer function to replace those with JSON values. + JSON.stringify(undefined) returns undefined. + + The optional space parameter produces a stringification of the + value that is filled with line breaks and indentation to make it + easier to read. + + If the space parameter is a non-empty string, then that string will + be used for indentation. If the space parameter is a number, then + the indentation will be that many spaces. + + Example: + + text = JSON.stringify(['e', {pluribus: 'unum'}]); + // text is '["e",{"pluribus":"unum"}]' + + + text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); + // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' + + text = JSON.stringify([new Date()], function (key, value) { + return this[key] instanceof Date ? + 'Date(' + this[key] + ')' : value; + }); + // text is '["Date(---current time---)"]' + + + JSON.parse(text, reviver) + This method parses a JSON text to produce an object or array. + It can throw a SyntaxError exception. + + The optional reviver parameter is a function that can filter and + transform the results. It receives each of the keys and values, + and its return value is used instead of the original value. + If it returns what it received, then the structure is not modified. + If it returns undefined then the member is deleted. + + Example: + + // Parse the text. Values that look like ISO date strings will + // be converted to Date objects. + + myData = JSON.parse(text, function (key, value) { + var a; + if (typeof value === 'string') { + a = +/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); + if (a) { + return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], + +a[5], +a[6])); + } + } + return value; + }); + + myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { + var d; + if (typeof value === 'string' && + value.slice(0, 5) === 'Date(' && + value.slice(-1) === ')') { + d = new Date(value.slice(5, -1)); + if (d) { + return d; + } + } + return value; + }); + + + This is a reference implementation.

UUIDS.\n\nFeatures:\n\n* Generate RFC4122 version 1 or version 4 UUIDs\n* Runs in node.js and all browsers.\n* Registered as a [ComponentJS](https://github.com/component/component) [component](https://github.com/component/component/wiki/Components) ('broofa/node-uuid').\n* Cryptographically strong random # generation on supporting platforms\n* 1.1K minified and gzip'ed (Want something smaller? Check this [crazy shit](https://gist.github.com/982883) out! )\n* [Annotated source code](http://broofa.github.com/node-uuid/docs/uuid.html)\n\n## Getting Started\n\nInstall it in your browser:\n\n```html\n\n```\n\nOr in node.js:\n\n```\nnpm install node-uuid\n```\n\n```javascript\nvar uuid = require('node-uuid');\n```\n\nThen create some ids ...\n\n```javascript\n// Generate a v1 (time-based) id\nuuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'\n\n// Generate a v4 (random) id\nuuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'\n```\n\n## API\n\n### uuid.v1([`options` [, `buffer` [, `offset`]]])\n\nGenerate and return a RFC4122 v1 (timestamp-based) UUID.\n\n* `options` - (Object) Optional uuid state to apply. Properties may include:\n\n * `node` - (Array) Node id as Array of 6 bytes (per 4.1.6). Default: Randomly generated ID. See note 1.\n * `clockseq` - (Number between 0 - 0x3fff) RFC clock sequence. Default: An internally maintained clockseq is used.\n * `msecs` - (Number | Date) Time in milliseconds since unix Epoch. Default: The current time is used.\n * `nsecs` - (Number between 0-9999) additional time, in 100-nanosecond units. Ignored if `msecs` is unspecified. Default: internal uuid counter is used, as per 4.2.1.2.\n\n* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.\n* `offset` - (Number) Starting index in `buffer` at which to begin writing.\n\nReturns `buffer`, if specified, otherwise the string form of the UUID\n\nNotes:\n\n1. The randomly generated node id is only guaranteed to stay constant for the lifetime of the current JS runtime. (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)\n\nExample: Generate string UUID with fully-specified options\n\n```javascript\nuuid.v1({\n node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],\n clockseq: 0x1234,\n msecs: new Date('2011-11-01').getTime(),\n nsecs: 5678\n}); // -> \"710b962e-041c-11e1-9234-0123456789ab\"\n```\n\nExample: In-place generation of two binary IDs\n\n```javascript\n// Generate two ids in an array\nvar arr = new Array(32); // -> []\nuuid.v1(null, arr, 0); // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15]\nuuid.v1(null, arr, 16); // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15 02 a3 1c b0 14 32 11 e1 85 58 0b 48 8e 4f c1 15]\n\n// Optionally use uuid.unparse() to get stringify the ids\nuuid.unparse(buffer); // -> '02a2ce90-1432-11e1-8558-0b488e4fc115'\nuuid.unparse(buffer, 16) // -> '02a31cb0-1432-11e1-8558-0b488e4fc115'\n```\n\n### uuid.v4([`options` [, `buffer` [, `offset`]]])\n\nGenerate and return a RFC4122 v4 UUID.\n\n* `options` - (Object) Optional uuid state to apply. Properties may include:\n\n * `random` - (Number[16]) Array of 16 numbers (0-255) to use in place of randomly generated values\n * `rng` - (Function) Random # generator to use. Set to one of the built-in generators - `uuid.mathRNG` (all platforms), `uuid.nodeRNG` (node.js only), `uuid.whatwgRNG` (WebKit only) - or a custom function that returns an array[16] of byte values.\n\n* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.\n* `offset` - (Number) Starting index in `buffer` at which to begin writing.\n\nReturns `buffer`, if specified, otherwise the string form of the UUID\n\nExample: Generate string UUID with fully-specified options\n\n```javascript\nuuid.v4({\n random: [\n 0x10, 0x91, 0x56, 0xbe, 0xc4, 0xfb, 0xc1, 0xea,\n 0x71, 0xb4, 0xef, 0xe1, 0x67, 0x1c, 0x58, 0x36\n ]\n});\n// -> \"109156be-c4fb-41ea-b1b4-efe1671c5836\"\n```\n\nExample: Generate two IDs in a single buffer\n\n```javascript\nvar buffer = new Array(32); // (or 'new Buffer' in node.js)\nuuid.v4(null, buffer, 0);\nuuid.v4(null, buffer, 16);\n```\n\n### uuid.parse(id[, buffer[, offset]])\n### uuid.unparse(buffer[, offset])\n\nParse and unparse UUIDs\n\n * `id` - (String) UUID(-like) string\n * `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written. Default: A new Array or Buffer is used\n * `offset` - (Number) Starting index in `buffer` at which to begin writing. Default: 0\n\nExample parsing and unparsing a UUID string\n\n```javascript\nvar bytes = uuid.parse('797ff043-11eb-11e1-80d6-510998755d10'); // -> \nvar string = uuid.unparse(bytes); // -> '797ff043-11eb-11e1-80d6-510998755d10'\n```\n\n### uuid.noConflict()\n\n(Browsers only) Set `uuid` property back to it's previous value.\n\nReturns the node-uuid object.\n\nExample:\n\n```javascript\nvar myUuid = uuid.noConflict();\nmyUuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'\n```\n\n## Deprecated APIs\n\nSupport for the following v1.2 APIs is available in v1.3, but is deprecated and will be removed in the next major version.\n\n### uuid([format [, buffer [, offset]]])\n\nuuid() has become uuid.v4(), and the `format` argument is now implicit in the `buffer` argument. (i.e. if you specify a buffer, the format is assumed to be binary).\n\n### uuid.BufferClass\n\nThe class of container created when generating binary uuid data if no buffer argument is specified. This is expected to go away, with no replacement API.\n\n## Testing\n\nIn node.js\n\n```\n> cd test\n> node test.js\n```\n\nIn Browser\n\n```\nopen test/test.html\n```\n\n### Benchmarking\n\nRequires node.js\n\n```\nnpm install uuid uuid-js\nnode benchmark/benchmark.js\n```\n\nFor a more complete discussion of node-uuid performance, please see the `benchmark/README.md` file, and the [benchmark wiki](https://github.com/broofa/node-uuid/wiki/Benchmark)\n\nFor browser performance [checkout the JSPerf tests](http://jsperf.com/node-uuid-performance).\n\n## Release notes\n\n### 1.4.0\n\n* Improved module context detection\n* Removed public RNG functions\n\n### 1.3.2\n\n* Improve tests and handling of v1() options (Issue #24)\n* Expose RNG option to allow for perf testing with different generators\n\n### 1.3.0\n\n* Support for version 1 ids, thanks to [@ctavan](https://github.com/ctavan)!\n* Support for node.js crypto API\n* De-emphasizing performance in favor of a) cryptographic quality PRNGs where available and b) more manageable code\n", + "readmeFilename": "README.md", + "bugs": { + "url": "https://github.com/broofa/node-uuid/issues" + }, + "_id": "node-uuid@1.4.1", + "dist": { + "shasum": "f542a538b863ade9a3fbe6b875a4f6ed53edfe54" + }, + "_from": "node-uuid@", + "_resolved": "https://registry.npmjs.org/node-uuid/-/node-uuid-1.4.1.tgz" +} diff --git a/node_modules/node-uuid/uuid.js b/node_modules/node-uuid/uuid.js new file mode 100644 index 00000000..2fac6dc4 --- /dev/null +++ b/node_modules/node-uuid/uuid.js @@ -0,0 +1,245 @@ +// uuid.js +// +// Copyright (c) 2010-2012 Robert Kieffer +// MIT License - http://opensource.org/licenses/mit-license.php + +(function() { + var _global = this; + + // Unique ID creation requires a high quality random # generator.

Instead of +socket.io using two `WebSocket` connections, it'll use one. + +The following example defines a socket that listens on '/chat' and one for +'/news': + +#### Server side + +```js +var io = require('socket.io').listen(80); + +var chat = io + .of('/chat') + .on('connection', function (socket) { + socket.emit('a message', { that: 'only', '/chat': 'will get' }); + chat.emit('a message', { everyone: 'in', '/chat': 'will get' }); + }); + +var news = io + .of('/news'); + .on('connection', function (socket) { + socket.emit('item', { news: 'item' }); + }); +``` + +#### Client side: + +```html + +``` + +### Sending volatile messages. + +Sometimes certain messages can be dropped. Let's say you have an app that +shows realtime tweets for the keyword `bieber`. + +If a certain client is not ready to receive messages (because of network slowness +or other issues, or because he's connected through long polling and is in the +middle of a request-response cycle), if he doesn't receive ALL the tweets related +to bieber your application won't suffer. + +In that case, you might want to send those messages as volatile messages. + +#### Server side + +```js +var io = require('socket.io').listen(80); + +io.sockets.on('connection', function (socket) { + var tweets = setInterval(function () { + getBieberTweet(function (tweet) { + socket.volatile.emit('bieber tweet', tweet); + }); + }, 100); + + socket.on('disconnect', function () { + clearInterval(tweets); + }); +}); +``` + +#### Client side + +In the client side, messages are received the same way whether they're volatile +or not. + +### Getting acknowledgements + +Sometimes, you might want to get a callback when the client confirmed the message +reception. + +To do this, simply pass a function as the last parameter of `.send` or `.emit`. +What's more, when you use `.emit`, the acknowledgement is done by you, which +means you can also pass data along: + +#### Server side + +```js +var io = require('socket.io').listen(80); + +io.sockets.on('connection', function (socket) { + socket.on('ferret', function (name, fn) { + fn('woot'); + }); +}); +``` + +#### Client side + +```html + +``` + +### Broadcasting messages + +To broadcast, simply add a `broadcast` flag to `emit` and `send` method calls. +Broadcasting means sending a message to everyone else except for the socket +that starts it. + +#### Server side + +```js +var io = require('socket.io').listen(80); + +io.sockets.on('connection', function (socket) { + socket.broadcast.emit('user connected'); + socket.broadcast.json.send({ a: 'message' }); +}); +``` + +### Rooms + +Sometimes you want to put certain sockets in the same room, so that it's easy +to broadcast to all of them together. + +Think of this as built-in channels for sockets. Sockets `join` and `leave` +rooms in each socket. + +#### Server side + +```js +var io = require('socket.io').listen(80); + +io.sockets.on('connection', function (socket) { + socket.join('justin bieber fans'); + socket.broadcast.to('justin bieber fans').emit('new fan'); + io.sockets.in('rammstein fans').emit('new non-fan'); +}); +``` + +### Using it just as a cross-browser WebSocket + +If you just want the WebSocket semantics, you can do that too. +Simply leverage `send` and listen on the `message` event: + +#### Server side + +```js +var io = require('socket.io').listen(80); + +io.sockets.on('connection', function (socket) { + socket.on('message', function () { }); + socket.on('disconnect', function () { }); +}); +``` + +#### Client side + +```html + +``` + +### Changing configuration + +Configuration in socket.io is TJ-style: + +#### Server side + +```js +var io = require('socket.io').listen(80);

So it you can just listen\nfor all the events that a `net` based server emits etc. But there is one extra event, the `connect_failed`\nevent. This event is triggered when we are unable to listen on the supplied port number.\n\n### createServer\nCreates a new server instance and accepts 2 optional arguments:\n\n- `options` **Object** Options to configure the server instance\n - `log` **Boolean** Enable logging to STDOUT and STDERR (defaults to true)\n- `origins` **Array** An Array of origins that are allowed by the server (defaults to *:*)\n\n```js\nvar pf = require('policyfile');\npf.createServer();\npf.listen();\n```\n\n#### server.listen\nStart listening on the server and it takes 3 optional arguments\n\n- `port` **Number** On which port number should we listen? (defaults to 843, which is the first port number the FlashPlayer checks)\n- `server` **Server** A http server, if we are unable to accept requests or run the server we can also answer the policy requests inline over the supplied HTTP server.\n- `callback` **Function** A callback function that is called when listening to the server was successful.\n\n```js\nvar pf = require('policyfile');\npf.createServer();\npf.listen(1337, function(){\n console.log(':3 yay')\n});\n```\n\nChanging port numbers can be handy if you do not want to run your server as root and have port 843 forward to a non root port number (aka a number above 1024).\n\n```js\nvar pf = require('policyfile')\n , http = require('http');\n\nserver = http.createServer(function(q,r){r.writeHead(200);r.end('hello world')});\nserver.listen(80);\n\npf.createServer();\npf.listen(1337, server, function(){\n console.log(':3 yay')\n});\n```\n\nSupport for serving inline requests over a existing HTTP connection as the FlashPlayer will first check port 843, but if it's unable to get a response there it will send a policy file request over port 80, which is usually your http server.\n\n#### server.add\nAdds more origins to the policy file you can add as many arguments as you like.\n\n```js\nvar pf = require('policyfile');\npf.createServer(['google.com:80']);\npf.listen();\npf.add('blog.3rd-Eden.com:80', 'blog.3rd-Eden.com:8080');

Commands that return a single line reply return JavaScript Strings, +integer replies return JavaScript Numbers, "bulk" replies return node Buffers, and "multi bulk" replies return a +JavaScript Array of node Buffers. `HGETALL` returns an Object with Buffers keyed by the hash keys. + +# API + +## Connection Events + +`client` will emit some events about the state of the connection to the Redis server. + +### "ready" + +`client` will emit `ready` a connection is established to the Redis server and the server reports +that it is ready to receive commands. Commands issued before the `ready` event are queued, +then replayed just before this event is emitted. + +### "connect" + +`client` will emit `connect` at the same time as it emits `ready` unless `client.options.no_ready_check` +is set. If this options is set, `connect` will be emitted when the stream is connected, and then +you are free to try to send commands. + +### "error" + +`client` will emit `error` when encountering an error connecting to the Redis server. + +Note that "error" is a special event type in node. If there are no listeners for an +"error" event, node will exit. This is usually what you want, but it can lead to some +cryptic error messages like this: + + mjr:~/work/node_redis (master)$ node example.js + + node.js:50 + throw e; + ^ + Error: ECONNREFUSED, Connection refused + at IOWatcher.callback (net:870:22) + at node.js:607:9 + +Not very useful in diagnosing the problem, but if your program isn't ready to handle this, +it is probably the right thing to just exit. + +`client` will also emit `error` if an exception is thrown inside of `node_redis` for whatever reason. +It would be nice to distinguish these two cases. + +### "end" + +`client` will emit `end` when an established Redis server connection has closed. + +### "drain" + +`client` will emit `drain` when the TCP connection to the Redis server has been buffering, but is now +writable. This event can be used to stream commands in to Redis and adapt to backpressure. Right now, +you need to check `client.command_queue.length` to decide when to reduce your send rate. Then you can +resume sending when you get `drain`. + +### "idle" + +`client` will emit `idle` when there are no outstanding commands that are awaiting a response. + +## redis.createClient(port, host, options) + +Create a new client connection. `port` defaults to `6379` and `host` defaults +to `127.0.0.1`. If you have `redis-server` running on the same computer as node, then the defaults for +port and host are probably fine. `options` in an object with the following possible properties: + +* `parser`: which Redis protocol reply parser to use. Defaults to `hiredis` if that module is installed. +This may also be set to `javascript`. +* `return_buffers`: defaults to `false`. If set to `true`, then all replies will be sent to callbacks as node Buffer +objects instead of JavaScript Strings. +* `detect_buffers`: default to `false`. If set to `true`, then replies will be sent to callbacks as node Buffer objects +if any of the input arguments to the original command were Buffer objects. +This option lets you switch between Buffers and Strings on a per-command basis, whereas `return_buffers` applies to +every command on a client. +* `socket_nodelay`: defaults to `true`. Whether to call setNoDelay() on the TCP stream, which disables the +Nagle algorithm on the underlying socket. Setting this option to `false` can result in additional throughput at the +cost of more latency. Most applications will want this set to `true`. +* `no_ready_check`: defaults to `false`. When a connection is established to the Redis server, the server might still +be loading the database from disk. While loading, the server not respond to any commands. To work around this, +`node_redis` has a "ready check" which sends the `INFO` command to the server. The response from the `INFO` command +indicates whether the server is ready for more commands. When ready, `node_redis` emits a `ready` event. +Setting `no_ready_check` to `true` will inhibit this check. +* `enable_offline_queue`: defaults to `true`. By default, if there is no active +connection to the redis server, commands are added to a queue and are executed +once the connection has been established. Setting `enable_offline_queue` to +`false` will disable this feature and the callback will be execute immediately +with an error, or an error will be thrown if no callback is specified. + +```js + var redis = require("redis"), + client = redis.createClient(null, null, {detect_buffers: true}); + + client.set("foo_rand000000000000", "OK"); + + // This will return a JavaScript String + client.get("foo_rand000000000000", function (err, reply) { + console.log(reply.toString()); // Will print `OK` + }); + + // This will return a Buffer since original key is specified as a Buffer + client.get(new Buffer("foo_rand000000000000"), function (err, reply) { + console.log(reply.toString()); // Will print `` + }); + client.end(); +``` + +`createClient()` returns a `RedisClient` object that is named `client` in all of the examples here. + +## client.auth(password, callback) + +When connecting to Redis servers that require authentication, the `AUTH` command must be sent as the +first command after connecting. This can be tricky to coordinate with reconnections, the ready check, +etc. To make this easier, `client.auth()` stashes `password` and will send it after each connection, +including reconnections. `callback` is invoked only once, after the response to the very first +`AUTH` command sent. +NOTE: Your call to `client.auth()` should not be inside the ready handler. If +you are doing this wrong, `client` will emit an error that looks +something like this `Error: Ready check failed: ERR operation not permitted`. + +## client.end() + +Forcibly close the connection to the Redis server. Note that this does not wait until all replies have been parsed. +If you want to exit cleanly, call `client.quit()` to send the `QUIT` command after you have handled all replies. + +This example closes the connection to the Redis server before the replies have been read. You probably don't +want to do this: + +```js + var redis = require("redis"), + client = redis.createClient(); + + client.set("foo_rand000000000000", "some fantastic value"); + client.get("foo_rand000000000000", function (err, reply) { + console.log(reply.toString()); + }); + client.end(); +``` + +`client.end()` is useful for timeout cases where something is stuck or taking too long and you want +to start over. + +## Friendlier hash commands + +Most Redis commands take a single String or an Array of Strings as arguments, and replies are sent back as a single String or an Array of Strings. +When dealing with hash values, there are a couple of useful exceptions to this. + +### client.hgetall(hash) + +The reply from an HGETALL command will be converted into a JavaScript Object by `node_redis`. That way you can interact +with the responses using JavaScript syntax. + +Example: + + client.hmset("hosts", "mjr", "1", "another", "23", "home", "1234"); + client.hgetall("hosts", function (err, obj) { + console.dir(obj); + }); + +Output: + + { mjr: '1', another: '23', home: '1234' } + +### client.hmset(hash, obj, [callback]) + +Multiple values in a hash can be set by supplying an object: + + client.HMSET(key2, { + "0123456789": "abcdefghij", // NOTE: the key and value must both be strings + "some manner of key": "a type of value" + }); + +The properties and values of this Object will be set as keys and values in the Redis hash. + +### client.hmset(hash, key1, val1, ... keyn, valn, [callback]) + +Multiple values may also be set by supplying a list: + + client.HMSET(key1, "0123456789", "abcdefghij", "some manner of key", "a type of value"); + + +## Publish / Subscribe + +Here is a simple example of the API for publish / subscribe. This program opens two +client connections, subscribes to a channel on one of them, and publishes to that +channel on the other: + +```js + var redis = require("redis"), + client1 = redis.createClient(), client2 = redis.createClient(), + msg_count = 0; + + client1.on("subscribe", function (channel, count) { + client2.publish("a nice channel", "I am sending a message."); + client2.publish("a nice channel", "I am sending a second message."); + client2.publish("a nice channel", "I am sending my last message."); + }); + + client1.on("message", function (channel, message) { + console.log("client1 channel " + channel + ": " + message); + msg_count += 1; + if (msg_count === 3) { + client1.unsubscribe(); + client1.end(); + client2.end(); + } + }); + + client1.incr("did a thing"); + client1.subscribe("a nice channel"); +``` + +When a client issues a `SUBSCRIBE` or `PSUBSCRIBE`, that connection is put into "pub/sub" mode. +At that point, only commands that modify the subscription set are valid. When the subscription +set is empty, the connection is put back into regular mode. + +If you need to send regular commands to Redis while in pub/sub mode, just open another connection. + +## Pub / Sub Events + +If a client has subscriptions active, it may emit these events: + +### "message" (channel, message) + +Client will emit `message` for every message received that matches an active subscription. +Listeners are passed the channel name as `channel` and the message Buffer as `message`. + +### "pmessage" (pattern, channel, message) + +Client will emit `pmessage` for every message received that matches an active subscription pattern. +Listeners are passed the original pattern used with `PSUBSCRIBE` as `pattern`, the sending channel +name as `channel`, and the message Buffer as `message`. + +### "subscribe" (channel, count) + +Client will emit `subscribe` in response to a `SUBSCRIBE` command. Listeners are passed the +channel name as `channel` and the new count of subscriptions for this client as `count`. + +### "psubscribe" (pattern, count) + +Client will emit `psubscribe` in response to a `PSUBSCRIBE` command. Listeners are passed the +original pattern as `pattern`, and the new count of subscriptions for this client as `count`. + +### "unsubscribe" (channel, count) + +Client will emit `unsubscribe` in response to a `UNSUBSCRIBE` command. Listeners are passed the +channel name as `channel` and the new count of subscriptions for this client as `count`. When +`count` is 0, this client has left pub/sub mode and no more pub/sub events will be emitted. + +### "punsubscribe" (pattern, count) + +Client will emit `punsubscribe` in response to a `PUNSUBSCRIBE` command. Listeners are passed the +channel name as `channel` and the new count of subscriptions for this client as `count`. When +`count` is 0, this client has left pub/sub mode and no more pub/sub events will be emitted. + +## client.multi([commands]) + +`MULTI` commands are queued up until an `EXEC` is issued, and then all commands are run atomically by +Redis. The interface in `node_redis` is to return an individual `Multi` object by calling `client.multi()`. + +```js + var redis = require("./index"), + client = redis.createClient(), set_size = 20; + + client.sadd("bigset", "a member"); + client.sadd("bigset", "another member"); + + while (set_size > 0) { + client.sadd("bigset", "member " + set_size); + set_size -= 1; + } + + // multi chain with an individual callback + client.multi() + .scard("bigset") + .smembers("bigset") + .keys("*", function (err, replies) { + // NOTE: code in this callback is NOT atomic + // this only happens after the the .exec call finishes. + client.mget(replies, redis.print); + }) + .dbsize() + .exec(function (err, replies) { + console.log("MULTI got " + replies.length + " replies"); + replies.forEach(function (reply, index) { + console.log("Reply " + index + ": " + reply.toString()); + }); + }); +``` + +`client.multi()` is a constructor that returns a `Multi` object. `Multi` objects share all of the +same command methods as `client` objects do. Commands are queued up inside the `Multi` object +until `Multi.exec()` is invoked. + +You can either chain together `MULTI` commands as in the above example, or you can queue individual +commands while still sending regular client command as in this example: + +```js + var redis = require("redis"), + client = redis.createClient(), multi; + + // start a separate multi command queue + multi = client.multi(); + multi.incr("incr thing", redis.print); + multi.incr("incr other thing", redis.print); + + // runs immediately + client.mset("incr thing", 100, "incr other thing", 1, redis.print); + + // drains multi queue and runs atomically + multi.exec(function (err, replies) { + console.log(replies); // 101, 2 + }); + + // you can re-run the same transaction if you like + multi.exec(function (err, replies) { + console.log(replies); // 102, 3 + client.quit(); + }); +``` + +In addition to adding commands to the `MULTI` queue individually, you can also pass an array +of commands and arguments to the constructor: + +```js + var redis = require("redis"), + client = redis.createClient(), multi; + + client.multi([ + ["mget", "multifoo", "multibar", redis.print], + ["incr", "multifoo"], + ["incr", "multibar"] + ]).exec(function (err, replies) { + console.log(replies); + }); +``` + + +## Monitor mode + +Redis supports the `MONITOR` command, which lets you see all commands received by the Redis server +across all client connections, including from other client libraries and other computers. + +After you send the `MONITOR` command, no other commands are valid on that connection. `node_redis` +will emit a `monitor` event for every new monitor message that comes across. The callback for the +`monitor` event takes a timestamp from the Redis server and an array of command arguments. + +Here is a simple example: + +```js + var client = require("redis").createClient(), + util = require("util"); + + client.monitor(function (err, res) { + console.log("Entering monitoring mode."); + }); + + client.on("monitor", function (time, args) { + console.log(time + ": " + util.inspect(args)); + }); +``` + +# Extras + +Some other things you might like to know about. + +## client.server_info + +After the ready probe completes, the results from the INFO command are saved in the `client.server_info` +object. + +The `versions` key contains an array of the elements of the version string for easy comparison. + + > client.server_info.redis_version + '2.3.0' + > client.server_info.versions + [ 2, 3, 0 ] + +## redis.print() + +A handy callback function for displaying return values when testing. Example: + +```js + var redis = require("redis"), + client = redis.createClient(); + + client.on("connect", function () { + client.set("foo_rand000000000000", "some fantastic value", redis.print); + client.get("foo_rand000000000000", redis.print); + }); +``` + +This will print: + + Reply: OK + Reply: some fantastic value + +Note that this program will not exit cleanly because the client is still connected. + +## redis.debug_mode + +Boolean to enable debug mode and protocol tracing. + +```js + var redis = require("redis"), + client = redis.createClient(); + + redis.debug_mode = true; + + client.on("connect", function () { + client.set("foo_rand000000000000", "some fantastic value"); + }); +``` + +This will display: + + mjr:~/work/node_redis (master)$ node ~/example.js + send command: *3 + $3 + SET + $20 + foo_rand000000000000 + $20 + some fantastic value + + on_data: +OK + +`send command` is data sent into Redis and `on_data` is data received from Redis. + +## client.send_command(command_name, args, callback) + +Used internally to send commands to Redis. For convenience, nearly all commands that are published on the Redis +Wiki have been added to the `client` object. However, if I missed any, or if new commands are introduced before +this library is updated, you can use `send_command()` to send arbitrary commands to Redis. + +All commands are sent as multi-bulk commands. `args` can either be an Array of arguments, or omitted. + +## client.connected + +Boolean tracking the state of the connection to the Redis server. + +## client.command_queue.length + +The number of commands that have been sent to the Redis server but not yet replied to. You can use this to +enforce some kind of maximum queue depth for commands while connected. + +Don't mess with `client.command_queue` though unless you really know what you are doing. + +## client.offline_queue.length + +The number of commands that have been queued up for a future connection. You can use this to enforce +some kind of maximum queue depth for pre-connection commands. + +## client.retry_delay + +Current delay in milliseconds before a connection retry will be attempted. This starts at `250`. + +## client.retry_backoff + +Multiplier for future retry timeouts. This should be larger than 1 to add more time between retries. +Defaults to 1.7. The default initial connection retry is 250, so the second retry will be 425, followed by 723.5, etc. + +### Commands with Optional and Keyword arguments + +This applies to anything that uses an optional `[WITHSCORES]` or `[LIMIT offset count]` in the [redis.io/commands](http://redis.io/commands) documentation. + +Example: +```js +var args = [ 'myzset', 1, 'one', 2, 'two', 3, 'three', 99, 'ninety-nine' ]; +client.zadd(args, function (err, response) { + if (err) throw err; + console.log('added '+response+' items.'); + + // -Infinity and +Infinity also work + var args1 = [ 'myzset', '+inf', '-inf' ]; + client.zrevrangebyscore(args1, function (err, response) { + if (err) throw err; + console.log('example1', response); + // write your code here + }); + + var max = 3, min = 1, offset = 1, count = 2; + var args2 = [ 'myzset', max, min, 'WITHSCORES', 'LIMIT', offset, count ]; + client.zrevrangebyscore(args2, function (err, response) { + if (err) throw err; + console.log('example2', response); + // write your code here + }); +}); +``` + +## TODO + +Better tests for auth, disconnect/reconnect, and all combinations thereof. + +Stream large set/get values into and out of Redis. Otherwise the entire value must be in node's memory. + +Performance can be better for very large values. + +I think there are more performance improvements left in there for smaller values, especially for large lists of small values. + +## How to Contribute +- open a pull request and then wait for feedback (if + [DTrejo](http://github.com/dtrejo) does not get back to you within 2 days, + comment again with indignation!) + +## Contributors +Some people have have added features and fixed bugs in `node_redis` other than me. + +Ordered by date of first contribution. +[Auto-generated](http://github.com/dtrejo/node-authors) on Wed Jul 25 2012 19:14:59 GMT-0700 (PDT). + +- [Matt Ranney aka `mranney`](https://github.com/mranney) +- [Tim-Smart aka `tim-smart`](https://github.com/tim-smart) +- [Tj Holowaychuk aka `visionmedia`](https://github.com/visionmedia) +- [rick aka `technoweenie`](https://github.com/technoweenie) +- [Orion Henry aka `orionz`](https://github.com/orionz) +- [Aivo Paas aka `aivopaas`](https://github.com/aivopaas) +- [Hank Sims aka `hanksims`](https://github.com/hanksims) +- [Paul Carey aka `paulcarey`](https://github.com/paulcarey) +- [Pieter Noordhuis aka `pietern`](https://github.com/pietern) +- [nithesh aka `nithesh`](https://github.com/nithesh) +- [Andy Ray aka `andy2ray`](https://github.com/andy2ray) +- [unknown aka `unknowdna`](https://github.com/unknowdna) +- [Dave Hoover aka `redsquirrel`](https://github.com/redsquirrel) +- [Vladimir Dronnikov aka `dvv`](https://github.com/dvv) +- [Umair Siddique aka `umairsiddique`](https://github.com/umairsiddique) +- [Louis-Philippe Perron aka `lp`](https://github.com/lp) +- [Mark Dawson aka `markdaws`](https://github.com/markdaws) +- [Ian Babrou aka `bobrik`](https://github.com/bobrik) +- [Felix Geisendörfer aka `felixge`](https://github.com/felixge) +- [Jean-Hugues Pinson aka `undefined`](https://github.com/undefined) +- [Maksim Lin aka `maks`](https://github.com/maks) +- [Owen Smith aka `orls`](https://github.com/orls) +- [Zachary Scott aka `zzak`](https://github.com/zzak) +- [TEHEK Firefox aka `TEHEK`](https://github.com/TEHEK) +- [Isaac Z.

Now node_redis will send an INFO command whenever it connects to a server. +If the info command indicates that the server is not ready, the client will keep trying until +the server is ready. Once it is ready, the client will emit a "ready" event as well as the +"connect" event. The client will queue up all commands sent before the server is ready, just +like it did before. When the server is ready, all offline/non-ready commands will be replayed. +This should be backward compatible with previous versions. + +To disable this ready check behavior, set `options.no_ready_check` when creating the client. + +As a side effect of this change, the key/val params from the info command are available as +`client.server_options`. Further, the version string is decomposed into individual elements +in `client.server_options.versions`. + +## v0.5.4 - February 11, 2011 + +Fix excess memory consumption from Queue backing store. + +Thanks to Gustaf Sjöberg. + +## v0.5.3 - February 5, 2011 + +Fix multi/exec error reply callback logic. + +Thanks to Stella Laurenzo. + +## v0.5.2 - January 18, 2011 + +Fix bug where unhandled error replies confuse the parser. + +## v0.5.1 - January 18, 2011 + +Fix bug where subscribe commands would not handle redis-server startup error properly. + +## v0.5.0 - December 29, 2010 + +Some bug fixes: + +* An important bug fix in reconnection logic.

It supports all Redis commands, including many recently added commands like EVAL from\nexperimental Redis server branches.\n\n\nInstall with:\n\n npm install redis\n\nPieter Noordhuis has provided a binding to the official `hiredis` C library, which is non-blocking and fast. To use `hiredis`, do:\n\n npm install hiredis redis\n\nIf `hiredis` is installed, `node_redis` will use it by default. Otherwise, a pure JavaScript parser will be used.\n\nIf you use `hiredis`, be sure to rebuild it whenever you upgrade your version of node. There are mysterious failures that can\nhappen between node and native code modules after a node upgrade.\n\n\n## Usage\n\nSimple example, included as `examples/simple.js`:\n\n```js\n var redis = require(\"redis\"),\n client = redis.createClient();\n\n // if you'd like to select database 3, instead of 0 (default), call\n // client.select(3, function() { /* ... */ });\n\n client.on(\"error\", function (err) {\n console.log(\"Error \" + err);\n });\n\n client.set(\"string key\", \"string val\", redis.print);\n client.hset(\"hash key\", \"hashtest 1\", \"some value\", redis.print);\n client.hset([\"hash key\", \"hashtest 2\", \"some other value\"], redis.print);\n client.hkeys(\"hash key\", function (err, replies) {\n console.log(replies.length + \" replies:\");\n replies.forEach(function (reply, i) {\n console.log(\" \" + i + \": \" + reply);\n });\n client.quit();\n });\n```\n\nThis will display:\n\n mjr:~/work/node_redis (master)$ node example.js\n Reply: OK\n Reply: 0\n Reply: 0\n 2 replies:\n 0: hashtest 1\n 1: hashtest 2\n mjr:~/work/node_redis (master)$\n\n\n## Performance\n\nHere are typical results of `multi_bench.js` which is similar to `redis-benchmark` from the Redis distribution.\nIt uses 50 concurrent connections with no pipelining.\n\nJavaScript parser:\n\n PING: 20000 ops 42283.30 ops/sec 0/5/1.182\n SET: 20000 ops 32948.93 ops/sec 1/7/1.515\n GET: 20000 ops 28694.40 ops/sec 0/9/1.740\n INCR: 20000 ops 39370.08 ops/sec 0/8/1.269\n LPUSH: 20000 ops 36429.87 ops/sec 0/8/1.370\n LRANGE (10 elements): 20000 ops 9891.20 ops/sec 1/9/5.048\n LRANGE (100 elements): 20000 ops 1384.56 ops/sec 10/91/36.072\n\nhiredis parser:\n\n PING: 20000 ops 46189.38 ops/sec 1/4/1.082\n SET: 20000 ops 41237.11 ops/sec 0/6/1.210\n GET: 20000 ops 39682.54 ops/sec 1/7/1.257\n INCR: 20000 ops 40080.16 ops/sec 0/8/1.242\n LPUSH: 20000 ops 41152.26 ops/sec 0/3/1.212\n LRANGE (10 elements): 20000 ops 36563.07 ops/sec 1/8/1.363\n LRANGE (100 elements): 20000 ops 21834.06 ops/sec 0/9/2.287\n\nThe performance of `node_redis` improves dramatically with pipelining, which happens automatically in most normal programs.\n\n\n### Sending Commands\n\nEach Redis command is exposed as a function on the `client` object.\nAll functions take either an `args` Array plus optional `callback` Function or\na variable number of individual arguments followed by an optional callback.\nHere is an example of passing an array of arguments and a callback:\n\n client.mset([\"test keys 1\", \"test val 1\", \"test keys 2\", \"test val 2\"], function (err, res) {});\n\nHere is that same call in the second style:\n\n client.mset(\"test keys 1\", \"test val 1\", \"test keys 2\", \"test val 2\", function (err, res) {});\n\nNote that in either form the `callback` is optional:\n\n client.set(\"some key\", \"some val\");\n client.set([\"some other key\", \"some val\"]);\n\nIf the key is missing, reply will be null (probably):\n\n client.get(\"missingkey\", function(err, reply) {\n // reply is null when the key is missing\n console.log(reply);\n });\n\nFor a list of Redis commands, see [Redis Command Reference](http://redis.io/commands)\n\nThe commands can be specified in uppercase or lowercase for convenience. `client.get()` is the same as `client.GET()`.\n\nMinimal parsing is done on the replies. Commands that return a single line reply return JavaScript Strings,\ninteger replies return JavaScript Numbers, \"bulk\" replies return node Buffers, and \"multi bulk\" replies return a\nJavaScript Array of node Buffers. `HGETALL` returns an Object with Buffers keyed by the hash keys.\n\n# API\n\n## Connection Events\n\n`client` will emit some events about the state of the connection to the Redis server.\n\n### \"ready\"\n\n`client` will emit `ready` a connection is established to the Redis server and the server reports\nthat it is ready to receive commands. Commands issued before the `ready` event are queued,\nthen replayed just before this event is emitted.\n\n### \"connect\"\n\n`client` will emit `connect` at the same time as it emits `ready` unless `client.options.no_ready_check`\nis set. If this options is set, `connect` will be emitted when the stream is connected, and then\nyou are free to try to send commands.\n\n### \"error\"\n\n`client` will emit `error` when encountering an error connecting to the Redis server.\n\nNote that \"error\" is a special event type in node. If there are no listeners for an\n\"error\" event, node will exit. This is usually what you want, but it can lead to some\ncryptic error messages like this:\n\n mjr:~/work/node_redis (master)$ node example.js\n\n node.js:50\n throw e;\n ^\n Error: ECONNREFUSED, Connection refused\n at IOWatcher.callback (net:870:22)\n at node.js:607:9\n\nNot very useful in diagnosing the problem, but if your program isn't ready to handle this,\nit is probably the right thing to just exit.\n\n`client` will also emit `error` if an exception is thrown inside of `node_redis` for whatever reason.\nIt would be nice to distinguish these two cases.\n\n### \"end\"\n\n`client` will emit `end` when an established Redis server connection has closed.\n\n### \"drain\"\n\n`client` will emit `drain` when the TCP connection to the Redis server has been buffering, but is now\nwritable. This event can be used to stream commands in to Redis and adapt to backpressure. Right now,\nyou need to check `client.command_queue.length` to decide when to reduce your send rate. Then you can\nresume sending when you get `drain`.\n\n### \"idle\"\n\n`client` will emit `idle` when there are no outstanding commands that are awaiting a response.\n\n## redis.createClient(port, host, options)\n\nCreate a new client connection. `port` defaults to `6379` and `host` defaults\nto `127.0.0.1`. If you have `redis-server` running on the same computer as node, then the defaults for\nport and host are probably fine. `options` in an object with the following possible properties:\n\n* `parser`: which Redis protocol reply parser to use. Defaults to `hiredis` if that module is installed.\nThis may also be set to `javascript`.\n* `return_buffers`: defaults to `false`. If set to `true`, then all replies will be sent to callbacks as node Buffer\nobjects instead of JavaScript Strings.\n* `detect_buffers`: default to `false`. If set to `true`, then replies will be sent to callbacks as node Buffer objects\nif any of the input arguments to the original command were Buffer objects.\nThis option lets you switch between Buffers and Strings on a per-command basis, whereas `return_buffers` applies to\nevery command on a client.\n* `socket_nodelay`: defaults to `true`. Whether to call setNoDelay() on the TCP stream, which disables the\nNagle algorithm on the underlying socket. Setting this option to `false` can result in additional throughput at the\ncost of more latency. Most applications will want this set to `true`.\n* `no_ready_check`: defaults to `false`. When a connection is established to the Redis server, the server might still\nbe loading the database from disk. While loading, the server not respond to any commands. To work around this,\n`node_redis` has a \"ready check\" which sends the `INFO` command to the server. The response from the `INFO` command\nindicates whether the server is ready for more commands. When ready, `node_redis` emits a `ready` event.\nSetting `no_ready_check` to `true` will inhibit this check.\n* `enable_offline_queue`: defaults to `true`. By default, if there is no active\nconnection to the redis server, commands are added to a queue and are executed\nonce the connection has been established. Setting `enable_offline_queue` to\n`false` will disable this feature and the callback will be execute immediately\nwith an error, or an error will be thrown if no callback is specified.\n\n```js\n var redis = require(\"redis\"),\n client = redis.createClient(null, null, {detect_buffers: true});\n\n client.set(\"foo_rand000000000000\", \"OK\");\n\n // This will return a JavaScript String\n client.get(\"foo_rand000000000000\", function (err, reply) {\n console.log(reply.toString()); // Will print `OK`\n });\n\n // This will return a Buffer since original key is specified as a Buffer\n client.get(new Buffer(\"foo_rand000000000000\"), function (err, reply) {\n console.log(reply.toString()); // Will print ``\n });\n client.end();\n```\n\n`createClient()` returns a `RedisClient` object that is named `client` in all of the examples here.\n\n## client.auth(password, callback)\n\nWhen connecting to Redis servers that require authentication, the `AUTH` command must be sent as the\nfirst command after connecting. This can be tricky to coordinate with reconnections, the ready check,\netc. To make this easier, `client.auth()` stashes `password` and will send it after each connection,\nincluding reconnections. `callback` is invoked only once, after the response to the very first\n`AUTH` command sent.\nNOTE: Your call to `client.auth()` should not be inside the ready handler. If\nyou are doing this wrong, `client` will emit an error that looks\nsomething like this `Error: Ready check failed: ERR operation not permitted`.\n\n## client.end()\n\nForcibly close the connection to the Redis server. Note that this does not wait until all replies have been parsed.\nIf you want to exit cleanly, call `client.quit()` to send the `QUIT` command after you have handled all replies.\n\nThis example closes the connection to the Redis server before the replies have been read. You probably don't\nwant to do this:\n\n```js\n var redis = require(\"redis\"),\n client = redis.createClient();\n\n client.set(\"foo_rand000000000000\", \"some fantastic value\");\n client.get(\"foo_rand000000000000\", function (err, reply) {\n console.log(reply.toString());\n });\n client.end();\n```\n\n`client.end()` is useful for timeout cases where something is stuck or taking too long and you want\nto start over.\n\n## Friendlier hash commands\n\nMost Redis commands take a single String or an Array of Strings as arguments, and replies are sent back as a single String or an Array of Strings.\nWhen dealing with hash values, there are a couple of useful exceptions to this.\n\n### client.hgetall(hash)\n\nThe reply from an HGETALL command will be converted into a JavaScript Object by `node_redis`. That way you can interact\nwith the responses using JavaScript syntax.\n\nExample:\n\n client.hmset(\"hosts\", \"mjr\", \"1\", \"another\", \"23\", \"home\", \"1234\");\n client.hgetall(\"hosts\", function (err, obj) {\n console.dir(obj);\n });\n\nOutput:\n\n { mjr: '1', another: '23', home: '1234' }\n\n### client.hmset(hash, obj, [callback])\n\nMultiple values in a hash can be set by supplying an object:\n\n client.HMSET(key2, {\n \"0123456789\": \"abcdefghij\", // NOTE: the key and value must both be strings\n \"some manner of key\": \"a type of value\"\n });\n\nThe properties and values of this Object will be set as keys and values in the Redis hash.\n\n### client.hmset(hash, key1, val1, ... keyn, valn, [callback])\n\nMultiple values may also be set by supplying a list:\n\n client.HMSET(key1, \"0123456789\", \"abcdefghij\", \"some manner of key\", \"a type of value\");\n\n\n## Publish / Subscribe\n\nHere is a simple example of the API for publish / subscribe. This program opens two\nclient connections, subscribes to a channel on one of them, and publishes to that\nchannel on the other:\n\n```js\n var redis = require(\"redis\"),\n client1 = redis.createClient(), client2 = redis.createClient(),\n msg_count = 0;\n\n client1.on(\"subscribe\", function (channel, count) {\n client2.publish(\"a nice channel\", \"I am sending a message.\");\n client2.publish(\"a nice channel\", \"I am sending a second message.\");\n client2.publish(\"a nice channel\", \"I am sending my last message.\");\n });\n\n client1.on(\"message\", function (channel, message) {\n console.log(\"client1 channel \" + channel + \": \" + message);\n msg_count += 1;\n if (msg_count === 3) {\n client1.unsubscribe();\n client1.end();\n client2.end();\n }\n });\n\n client1.incr(\"did a thing\");\n client1.subscribe(\"a nice channel\");\n```\n\nWhen a client issues a `SUBSCRIBE` or `PSUBSCRIBE`, that connection is put into \"pub/sub\" mode.\nAt that point, only commands that modify the subscription set are valid. When the subscription\nset is empty, the connection is put back into regular mode.\n\nIf you need to send regular commands to Redis while in pub/sub mode, just open another connection.\n\n## Pub / Sub Events\n\nIf a client has subscriptions active, it may emit these events:\n\n### \"message\" (channel, message)\n\nClient will emit `message` for every message received that matches an active subscription.\nListeners are passed the channel name as `channel` and the message Buffer as `message`.\n\n### \"pmessage\" (pattern, channel, message)\n\nClient will emit `pmessage` for every message received that matches an active subscription pattern.\nListeners are passed the original pattern used with `PSUBSCRIBE` as `pattern`, the sending channel\nname as `channel`, and the message Buffer as `message`.\n\n### \"subscribe\" (channel, count)\n\nClient will emit `subscribe` in response to a `SUBSCRIBE` command. Listeners are passed the\nchannel name as `channel` and the new count of subscriptions for this client as `count`.\n\n### \"psubscribe\" (pattern, count)\n\nClient will emit `psubscribe` in response to a `PSUBSCRIBE` command. Listeners are passed the\noriginal pattern as `pattern`, and the new count of subscriptions for this client as `count`.\n\n### \"unsubscribe\" (channel, count)\n\nClient will emit `unsubscribe` in response to a `UNSUBSCRIBE` command. Listeners are passed the\nchannel name as `channel` and the new count of subscriptions for this client as `count`. When\n`count` is 0, this client has left pub/sub mode and no more pub/sub events will be emitted.\n\n### \"punsubscribe\" (pattern, count)\n\nClient will emit `punsubscribe` in response to a `PUNSUBSCRIBE` command. Listeners are passed the\nchannel name as `channel` and the new count of subscriptions for this client as `count`. When\n`count` is 0, this client has left pub/sub mode and no more pub/sub events will be emitted.\n\n## client.multi([commands])\n\n`MULTI` commands are queued up until an `EXEC` is issued, and then all commands are run atomically by\nRedis. The interface in `node_redis` is to return an individual `Multi` object by calling `client.multi()`.\n\n```js\n var redis = require(\"./index\"),\n client = redis.createClient(), set_size = 20;\n\n client.sadd(\"bigset\", \"a member\");\n client.sadd(\"bigset\", \"another member\");\n\n while (set_size > 0) {\n client.sadd(\"bigset\", \"member \" + set_size);\n set_size -= 1;\n }\n\n // multi chain with an individual callback\n client.multi()\n .scard(\"bigset\")\n .smembers(\"bigset\")\n .keys(\"*\", function (err, replies) {\n // NOTE: code in this callback is NOT atomic\n // this only happens after the the .exec call finishes.\n client.mget(replies, redis.print);\n })\n .dbsize()\n .exec(function (err, replies) {\n console.log(\"MULTI got \" + replies.length + \" replies\");\n replies.forEach(function (reply, index) {\n console.log(\"Reply \" + index + \": \" + reply.toString());\n });\n });\n```\n\n`client.multi()` is a constructor that returns a `Multi` object. `Multi` objects share all of the\nsame command methods as `client` objects do. Commands are queued up inside the `Multi` object\nuntil `Multi.exec()` is invoked.\n\nYou can either chain together `MULTI` commands as in the above example, or you can queue individual\ncommands while still sending regular client command as in this example:\n\n```js\n var redis = require(\"redis\"),\n client = redis.createClient(), multi;\n\n // start a separate multi command queue\n multi = client.multi();\n multi.incr(\"incr thing\", redis.print);\n multi.incr(\"incr other thing\", redis.print);\n\n // runs immediately\n client.mset(\"incr thing\", 100, \"incr other thing\", 1, redis.print);\n\n // drains multi queue and runs atomically\n multi.exec(function (err, replies) {\n console.log(replies); // 101, 2\n });\n\n // you can re-run the same transaction if you like\n multi.exec(function (err, replies) {\n console.log(replies); // 102, 3\n client.quit();\n });\n```\n\nIn addition to adding commands to the `MULTI` queue individually, you can also pass an array\nof commands and arguments to the constructor:\n\n```js\n var redis = require(\"redis\"),\n client = redis.createClient(), multi;\n\n client.multi([\n [\"mget\", \"multifoo\", \"multibar\", redis.print],\n [\"incr\", \"multifoo\"],\n [\"incr\", \"multibar\"]\n ]).exec(function (err, replies) {\n console.log(replies);\n });\n```\n\n\n## Monitor mode\n\nRedis supports the `MONITOR` command, which lets you see all commands received by the Redis server\nacross all client connections, including from other client libraries and other computers.\n\nAfter you send the `MONITOR` command, no other commands are valid on that connection. `node_redis`\nwill emit a `monitor` event for every new monitor message that comes across. The callback for the\n`monitor` event takes a timestamp from the Redis server and an array of command arguments.\n\nHere is a simple example:\n\n```js\n var client = require(\"redis\").createClient(),\n util = require(\"util\");\n\n client.monitor(function (err, res) {\n console.log(\"Entering monitoring mode.\");\n });\n\n client.on(\"monitor\", function (time, args) {\n console.log(time + \": \" + util.inspect(args));\n });\n```\n\n# Extras\n\nSome other things you might like to know about.\n\n## client.server_info\n\nAfter the ready probe completes, the results from the INFO command are saved in the `client.server_info`\nobject.\n\nThe `versions` key contains an array of the elements of the version string for easy comparison.\n\n > client.server_info.redis_version\n '2.3.0'\n > client.server_info.versions\n [ 2, 3, 0 ]\n\n## redis.print()\n\nA handy callback function for displaying return values when testing. Example:\n\n```js\n var redis = require(\"redis\"),\n client = redis.createClient();\n\n client.on(\"connect\", function () {\n client.set(\"foo_rand000000000000\", \"some fantastic value\", redis.print);\n client.get(\"foo_rand000000000000\", redis.print);\n });\n```\n\nThis will print:\n\n Reply: OK\n Reply: some fantastic value\n\nNote that this program will not exit cleanly because the client is still connected.\n\n## redis.debug_mode\n\nBoolean to enable debug mode and protocol tracing.\n\n```js\n var redis = require(\"redis\"),\n client = redis.createClient();\n\n redis.debug_mode = true;\n\n client.on(\"connect\", function () {\n client.set(\"foo_rand000000000000\", \"some fantastic value\");\n });\n```\n\nThis will display:\n\n mjr:~/work/node_redis (master)$ node ~/example.js\n send command: *3\n $3\n SET\n $20\n foo_rand000000000000\n $20\n some fantastic value\n\n on_data: +OK\n\n`send command` is data sent into Redis and `on_data` is data received from Redis.\n\n## client.send_command(command_name, args, callback)\n\nUsed internally to send commands to Redis. For convenience, nearly all commands that are published on the Redis\nWiki have been added to the `client` object. However, if I missed any, or if new commands are introduced before\nthis library is updated, you can use `send_command()` to send arbitrary commands to Redis.\n\nAll commands are sent as multi-bulk commands. `args` can either be an Array of arguments, or omitted.\n\n## client.connected\n\nBoolean tracking the state of the connection to the Redis server.\n\n## client.command_queue.length\n\nThe number of commands that have been sent to the Redis server but not yet replied to. You can use this to\nenforce some kind of maximum queue depth for commands while connected.\n\nDon't mess with `client.command_queue` though unless you really know what you are doing.\n\n## client.offline_queue.length\n\nThe number of commands that have been queued up for a future connection. You can use this to enforce\nsome kind of maximum queue depth for pre-connection commands.\n\n## client.retry_delay\n\nCurrent delay in milliseconds before a connection retry will be attempted. This starts at `250`.\n\n## client.retry_backoff\n\nMultiplier for future retry timeouts. This should be larger than 1 to add more time between retries.\nDefaults to 1.7. The default initial connection retry is 250, so the second retry will be 425, followed by 723.5, etc.\n\n### Commands with Optional and Keyword arguments\n\nThis applies to anything that uses an optional `[WITHSCORES]` or `[LIMIT offset count]` in the [redis.io/commands](http://redis.io/commands) documentation.\n\nExample:\n```js\nvar args = [ 'myzset', 1, 'one', 2, 'two', 3, 'three', 99, 'ninety-nine' ];\nclient.zadd(args, function (err, response) {\n if (err) throw err;\n console.log('added '+response+' items.');\n\n // -Infinity and +Infinity also work\n var args1 = [ 'myzset', '+inf', '-inf' ];\n client.zrevrangebyscore(args1, function (err, response) {\n if (err) throw err;\n console.log('example1', response);\n // write your code here\n });\n\n var max = 3, min = 1, offset = 1, count = 2;\n var args2 = [ 'myzset', max, min, 'WITHSCORES', 'LIMIT', offset, count ];\n client.zrevrangebyscore(args2, function (err, response) {\n if (err) throw err;\n console.log('example2', response);\n // write your code here\n });\n});\n```\n\n## TODO\n\nBetter tests for auth, disconnect/reconnect, and all combinations thereof.\n\nStream large set/get values into and out of Redis. Otherwise the entire value must be in node's memory.\n\nPerformance can be better for very large values.\n\nI think there are more performance improvements left in there for smaller values, especially for large lists of small values.\n\n## How to Contribute\n- open a pull request and then wait for feedback (if\n [DTrejo](http://github.com/dtrejo) does not get back to you within 2 days,\n comment again with indignation!)\n\n## Contributors\nSome people have have added features and fixed bugs in `node_redis` other than me.\n\nOrdered by date of first contribution.\n[Auto-generated](http://github.com/dtrejo/node-authors) on Wed Jul 25 2012 19:14:59 GMT-0700 (PDT).\n\n- [Matt Ranney aka `mranney`](https://github.com/mranney)\n- [Tim-Smart aka `tim-smart`](https://github.com/tim-smart)\n- [Tj Holowaychuk aka `visionmedia`](https://github.com/visionmedia)\n- [rick aka `technoweenie`](https://github.com/technoweenie)\n- [Orion Henry aka `orionz`](https://github.com/orionz)\n- [Aivo Paas aka `aivopaas`](https://github.com/aivopaas)\n- [Hank Sims aka `hanksims`](https://github.com/hanksims)\n- [Paul Carey aka `paulcarey`](https://github.com/paulcarey)\n- [Pieter Noordhuis aka `pietern`](https://github.com/pietern)\n- [nithesh aka `nithesh`](https://github.com/nithesh)\n- [Andy Ray aka `andy2ray`](https://github.com/andy2ray)\n- [unknown aka `unknowdna`](https://github.com/unknowdna)\n- [Dave Hoover aka `redsquirrel`](https://github.com/redsquirrel)\n- [Vladimir Dronnikov aka `dvv`](https://github.com/dvv)\n- [Umair Siddique aka `umairsiddique`](https://github.com/umairsiddique)\n- [Louis-Philippe Perron aka `lp`](https://github.com/lp)\n- [Mark Dawson aka `markdaws`](https://github.com/markdaws)\n- [Ian Babrou aka `bobrik`](https://github.com/bobrik)\n- [Felix Geisendörfer aka `felixge`](https://github.com/felixge)\n- [Jean-Hugues Pinson aka `undefined`](https://github.com/undefined)\n- [Maksim Lin aka `maks`](https://github.com/maks)\n- [Owen Smith aka `orls`](https://github.com/orls)\n- [Zachary Scott aka `zzak`](https://github.com/zzak)\n- [TEHEK Firefox aka `TEHEK`](https://github.com/TEHEK)\n- [Isaac Z.

If it is a string (such as '\t' or ' '), + it contains the characters used to indent at each level. + + This method produces a JSON text from a JavaScript value. + + When an object value is found, if the object contains a toJSON + method, its toJSON method will be called and the result will be + stringified. A toJSON method does not serialize: it returns the + value represented by the name/value pair that should be serialized, + or undefined if nothing should be serialized.

It will be passed the + key and value of each member, with this bound to the containing + object. The value that is returned from your method will be + serialized. If your method returns undefined, then the member will + be excluded from the serialization. + + If the replacer parameter is an array of strings, then it will be + used to select the members to be serialized. It filters the results + such that only members with keys listed in the replacer array are + stringified. + + Values that do not have JSON representations, such as undefined or + functions, will not be serialized. Such values in objects will be + dropped; in arrays they will be replaced with null. You can use + a replacer function to replace those with JSON values. + JSON.stringify(undefined) returns undefined. + + The optional space parameter produces a stringification of the + value that is filled with line breaks and indentation to make it + easier to read. + + If the space parameter is a non-empty string, then that string will + be used for indentation. If the space parameter is a number, then + the indentation will be that many spaces. + + Example: + + text = JSON.stringify(['e', {pluribus: 'unum'}]); + // text is '["e",{"pluribus":"unum"}]' + + + text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); + // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' + + text = JSON.stringify([new Date()], function (key, value) { + return this[key] instanceof Date ? + 'Date(' + this[key] + ')' : value; + }); + // text is '["Date(---current time---)"]' + + + JSON.parse(text, reviver) + This method parses a JSON text to produce an object or array. + It can throw a SyntaxError exception. + + The optional reviver parameter is a function that can filter and + transform the results. It receives each of the keys and values, + and its return value is used instead of the original value. + If it returns what it received, then the structure is not modified. + If it returns undefined then the member is deleted. + + Example: + + // Parse the text.

The parser tells the tokenizer whether the next token may be a regular expression or not. Without the parser, the tokenizer will fail if regular expression literals are used in the input.\n\nUsage:\nZeParser.parse(input);\n\nReturns a \"parse tree\" which is a tree of an array of arrays with tokens (regular objects) as leafs. Meta information embedded as properties (of the arrays and the tokens).\n\nZeParser.createParser(input);\n\nReturns a new ZeParser instance which has already parsed the input. Amongst others, the ZeParser instance will have the properties .tree, .wtree and .btree.\n\n.tree is the parse tree mentioned above.\n.wtree (\"white\" tree) is a regular array with all the tokens encountered (including whitespace, line terminators and comments)\n.btree (\"black\" tree) is just like .wtree but without the whitespace, line terminators and comments. This is what the specification would call the \"token stream\".\n\nI'm aware that the naming convention is a bit awkward. It's a tradeoff between short and descriptive. The streams are used quite often in the analysis.\n\nTokens are regular objects with several properties. Amongst them are .tokposw and .tokposw, they correspond with their own position in the .wtree and .btree.\n\nThe parser has two modes for parsing: simple and extended. Simple mode is mainly for just parsing and returning the streams and a simple parse tree. There's not so much meta information here and this mode is mainly built for speed. The other mode has everything required for Zeon to do its job. This mode is toggled by the instance property .ast, which is true by default :)\n\nNon-factory example:\n\nvar input = \"foo\";\nvar tree = []; // this should probably be refactored away some day\nvar tokenizer = new Tokenizer(input); // dito\nvar parser = new ZeParser(input, tokenizer, tree);\nparser.parse(); // returns tree..., should never throw errors\n", + "readmeFilename": "README", + "bugs": { + "url": "https://github.com/qfox/ZeParser/issues" + }, + "_id": "zeparser@0.0.5", + "dist": { + "shasum": "dd541e280c9ce8e83e41e3adc3f22fbe52747554" + }, + "_from": "zeparser@0.0.5", + "_resolved": "https://registry.npmjs.org/zeparser/-/zeparser-0.0.5.tgz" +} diff --git a/node_modules/socket.io/node_modules/socket.io-client/node_modules/active-x-obfuscator/node_modules/zeparser/test-parser.html b/node_modules/socket.io/node_modules/socket.io-client/node_modules/active-x-obfuscator/node_modules/zeparser/test-parser.html new file mode 100755 index 00000000..1ff5ff43 --- /dev/null +++ b/node_modules/socket.io/node_modules/socket.io-client/node_modules/active-x-obfuscator/node_modules/zeparser/test-parser.html @@ -0,0 +1,26 @@ + + + + Parser Test Suite Page + + + + (c) qfox.nl

    UglifyJS – a JavaScript parser/compressor/beautifier

    + + + + +
    +

    1 UglifyJS — a JavaScript parser/compressor/beautifier

    +
    + + +

    +This package implements a general-purpose JavaScript +parser/compressor/beautifier toolkit. It is developed on NodeJS, but it +should work on any JavaScript platform supporting the CommonJS module system +(and if your platform of choice doesn't support CommonJS, you can easily +implement it, or discard the exports.* lines from UglifyJS sources). +

    +

    +The tokenizer/parser generates an abstract syntax tree from JS code. You +can then traverse the AST to learn more about the code, or do various +manipulations on it. This part is implemented in parse-js.js and it's a +port to JavaScript of the excellent parse-js Common Lisp library from Marijn Haverbeke. +

    +

    +( See cl-uglify-js if you're looking for the Common Lisp version of +UglifyJS. ) +

    +

    +The second part of this package, implemented in process.js, inspects and +manipulates the AST generated by the parser to provide the following: +

    +
      +
    • ability to re-generate JavaScript code from the AST. Optionally + indented—you can use this if you want to “beautify†a program that has + been compressed, so that you can inspect the source. But you can also run + our code generator to print out an AST without any whitespace, so you + achieve compression as well. + +
      • +
    • shorten variable names (usually to single characters). Our mangler will + analyze the code and generate proper variable names, depending on scope + and usage, and is smart enough to deal with globals defined elsewhere, or + with eval() calls or with{} statements. In short, if eval() or + with{} are used in some scope, then all variables in that scope and any + variables in the parent scopes will remain unmangled, and any references + to such variables remain unmangled as well. + +
      • +
    • various small optimizations that may lead to faster code but certainly + lead to smaller code. Where possible, we do the following: + +
        +
      • foo["bar"] ==> foo.bar + +
        • +
      • remove block brackets {} + +
        • +
      • join consecutive var declarations: + var a = 10; var b = 20; ==> var a=10,b=20; + +
        • +
      • resolve simple constant expressions: 1 +2 * 3 ==> 7. We only do the + replacement if the result occupies less bytes; for example 1/3 would + translate to 0.333333333333, so in this case we don't replace it. + +
        • +
      • consecutive statements in blocks are merged into a sequence; in many + cases, this leaves blocks with a single statement, so then we can remove + the block brackets. + +
        • +
      • various optimizations for IF statements: + +
          +
        • if (foo) bar(); else baz(); ==> foo?bar():baz(); +
          • +
        • if (!foo) bar(); else baz(); ==> foo?baz():bar(); +
          • +
        • if (foo) bar(); ==> foo&&bar(); +
          • +
        • if (!foo) bar(); ==> foo||bar(); +
          • +
        • if (foo) return bar(); else return baz(); ==> return foo?bar():baz(); +
          • +
        • if (foo) return bar(); else something(); ==> {if(foo)return bar();something()} + +
          • +
        + +
        • +
      • remove some unreachable code and warn about it (code that follows a + return, throw, break or continue statement, except + function/variable declarations). + +
        • +
      • act a limited version of a pre-processor (c.f. the pre-processor of + C/C++) to allow you to safely replace selected global symbols with + specified values. When combined with the optimisations above this can + make UglifyJS operate slightly more like a compilation process, in + that when certain symbols are replaced by constant values, entire code + blocks may be optimised away as unreachable. +
        • +
      + +
      • +
    + + + +
    + +
    +

    1.1 Unsafe transformations

    +
    + + +

    +The following transformations can in theory break code, although they're +probably safe in most practical cases. To enable them you need to pass the +--unsafe flag. +

    + +
    + +
    +

    1.1.1 Calls involving the global Array constructor

    +
    + + +

    +The following transformations occur: +

    + + + +
    new Array(1, 2, 3, 4)  => [1,2,3,4]
+Array(a, b, c)         => [a,b,c]
+new Array(5)           => Array(5)
+new Array(a)           => Array(a)
+
    + + +

    +These are all safe if the Array name isn't redefined. JavaScript does allow +one to globally redefine Array (and pretty much everything, in fact) but I +personally don't see why would anyone do that. +

    +

    +UglifyJS does handle the case where Array is redefined locally, or even +globally but with a function or var declaration. Therefore, in the +following cases UglifyJS doesn't touch calls or instantiations of Array: +

    + + + +
    // case 1.  globally declared variable
+  var Array;
+  new Array(1, 2, 3);
+  Array(a, b);
+
+  // or (can be declared later)
+  new Array(1, 2, 3);
+  var Array;

    1.4 Usage

    +
    + + +

    +There is a command-line tool that exposes the functionality of this library +for your shell-scripting needs: +

    + + + +
    uglifyjs [ options... ] [ filename ]
+
    + + +

    +filename should be the last argument and should name the file from which +to read the JavaScript code. If you don't specify it, it will read code +from STDIN. +

    +

    +Supported options: +

    +
      +
    • -b or --beautify — output indented code; when passed, additional + options control the beautifier: + +
        +
      • -i N or --indent N — indentation level (number of spaces) + +
        • +
      • -q or --quote-keys — quote keys in literal objects (by default, + only keys that cannot be identifier names will be quotes). + +
        • +
      + +
      • +
    • --ascii — pass this argument to encode non-ASCII characters as + \uXXXX sequences. By default UglifyJS won't bother to do it and will + output Unicode characters instead. (the output is always encoded in UTF8, + but if you pass this option you'll only get ASCII). + +
      • +
    • -nm or --no-mangle — don't mangle names. + +
      • +
    • -nmf or --no-mangle-functions – in case you want to mangle variable + names, but not touch function names. + +
      • +
    • -ns or --no-squeeze — don't call ast_squeeze() (which does various + optimizations that result in smaller, less readable code). + +
      • +
    • -mt or --mangle-toplevel — mangle names in the toplevel scope too + (by default we don't do this). + +
      • +
    • --no-seqs — when ast_squeeze() is called (thus, unless you pass + --no-squeeze) it will reduce consecutive statements in blocks into a + sequence. For example, "a = 10; b = 20; foo();" will be written as + "a=10,b=20,foo();". In various occasions, this allows us to discard the + block brackets (since the block becomes a single statement). This is ON + by default because it seems safe and saves a few hundred bytes on some + libs that I tested it on, but pass --no-seqs to disable it. + +
      • +
    • --no-dead-code — by default, UglifyJS will remove code that is + obviously unreachable (code that follows a return, throw, break or + continue statement and is not a function/variable declaration). Pass + this option to disable this optimization. + +
      • +
    • -nc or --no-copyright — by default, uglifyjs will keep the initial + comment tokens in the generated code (assumed to be copyright information + etc.). If you pass this it will discard it. + +
      • +
    • -o filename or --output filename — put the result in filename. If + this isn't given, the result goes to standard output (or see next one). + +
      • +
    • --overwrite — if the code is read from a file (not from STDIN) and you + pass --overwrite then the output will be written in the same file. + +
      • +
    • --ast — pass this if you want to get the Abstract Syntax Tree instead + of JavaScript as output. Useful for debugging or learning more about the + internals. + +
      • +
    • -v or --verbose — output some notes on STDERR (for now just how long + each operation takes). + +
      • +
    • -d SYMBOL[=VALUE] or --define SYMBOL[=VALUE] — will replace + all instances of the specified symbol where used as an identifier + (except where symbol has properly declared by a var declaration or + use as function parameter or similar) with the specified value. This + argument may be specified multiple times to define multiple + symbols - if no value is specified the symbol will be replaced with + the value true, or you can specify a numeric value (such as + 1024), a quoted string value (such as ="object"= or + ='https://github.com'), or the name of another symbol or keyword (such as =null or document). + This allows you, for example, to assign meaningful names to key + constant values but discard the symbolic names in the uglified + version for brevity/efficiency, or when used wth care, allows + UglifyJS to operate as a form of conditional compilation + whereby defining appropriate values may, by dint of the constant + folding and dead code removal features above, remove entire + superfluous code blocks (e.g. completely remove instrumentation or + trace code for production use). + Where string values are being defined, the handling of quotes are + likely to be subject to the specifics of your command shell + environment, so you may need to experiment with quoting styles + depending on your platform, or you may find the option + --define-from-module more suitable for use. + +
      • +
    • -define-from-module SOMEMODULE — will load the named module (as + per the NodeJS require() function) and iterate all the exported + properties of the module defining them as symbol names to be defined + (as if by the --define option) per the name of each property + (i.e. without the module name prefix) and given the value of the + property. This is a much easier way to handle and document groups of + symbols to be defined rather than a large number of --define + options. + +
      • +
    • --unsafe — enable other additional optimizations that are known to be + unsafe in some contrived situations, but could still be generally useful. + For now only these: + +
        +
      • foo.toString() ==> foo+"" +
        • +
      • new Array(x,…) ==> [x,…] +
        • +
      • new Array(x) ==> Array(x) + +
        • +
      + +
      • +
    • --max-line-len (default 32K characters) — add a newline after around + 32K characters. I've seen both FF and Chrome croak when all the code was + on a single line of around 670K. Pass –max-line-len 0 to disable this + safety feature. + +
      • +
    • --reserved-names — some libraries rely on certain names to be used, as + pointed out in issue #92 and #81, so this option allow you to exclude such + names from the mangler. For example, to keep names require and $super + intact you'd specify –reserved-names "require,$super". + +
      • +
    • --inline-script – when you want to include the output literally in an + HTML <script> tag you can use this option to prevent </script from + showing up in the output. + +
      • +
    • --lift-vars – when you pass this, UglifyJS will apply the following + transformations (see the notes in API, ast_lift_variables): + +
        +
      • put all var declarations at the start of the scope +
        • +
      • make sure a variable is declared only once +
        • +
      • discard unused function arguments +
        • +
      • discard unused inner (named) functions +
        • +
      • finally, try to merge assignments into that one var declaration, if + possible. +
        • +
      + +
      • +
    + + + +
    + +
    +

    1.4.1 API

    +
    + + +

    +To use the library from JavaScript, you'd do the following (example for +NodeJS): +

    + + + +
    var jsp = require("uglify-js").parser;
+var pro = require("uglify-js").uglify;
+
+var orig_code = "... JS code here";
+var ast = jsp.parse(orig_code); // parse code and get the initial AST
+ast = pro.ast_mangle(ast); // get a new AST with mangled names
+ast = pro.ast_squeeze(ast); // get an AST with compression optimizations
+var final_code = pro.gen_code(ast); // compressed code here
+
    + + +

    +The above performs the full compression that is possible right now. As you +can see, there are a sequence of steps which you can apply. For example if +you want compressed output but for some reason you don't want to mangle +variable names, you would simply skip the line that calls +pro.ast_mangle(ast). +

    +

    +Some of these functions take optional arguments. Here's a description: +

    +
      +
    • jsp.parse(code, strict_semicolons) – parses JS code and returns an AST. + strict_semicolons is optional and defaults to false. If you pass + true then the parser will throw an error when it expects a semicolon and + it doesn't find it. For most JS code you don't want that, but it's useful + if you want to strictly sanitize your code. + +
      • +
    • pro.ast_lift_variables(ast) – merge and move var declarations to the + scop of the scope; discard unused function arguments or variables; discard + unused (named) inner functions. It also tries to merge assignments + following the var declaration into it. + +

      + If your code is very hand-optimized concerning var declarations, this + lifting variable declarations might actually increase size. For me it + helps out. On jQuery it adds 865 bytes (243 after gzip). YMMV. Also + note that (since it's not enabled by default) this operation isn't yet + heavily tested (please report if you find issues!). +

      +

      + Note that although it might increase the image size (on jQuery it gains + 865 bytes, 243 after gzip) it's technically more correct: in certain + situations, dead code removal might drop variable declarations, which + would not happen if the variables are lifted in advance. +

      +

      + Here's an example of what it does: +

      • +
    + + + + + +
    function f(a, b, c, d, e) {
+    var q;
+    var w;
+    w = 10;
+    q = 20;
+    for (var i = 1; i < 10; ++i) {
+        var boo = foo(a);
+    }
+    for (var i = 0; i < 1; ++i) {
+        var boo = bar(c);
+    }
+    function foo(){ ... }
+    function bar(){ ... }
+    function baz(){ ... }
+}
+
+// transforms into ==>
+
+function f(a, b, c) {
+    var i, boo, w = 10, q = 20;
+    for (i = 1; i < 10; ++i) {
+        boo = foo(a);
+    }
+    for (i = 0; i < 1; ++i) {
+        boo = bar(c);
+    }
+    function foo() { ... }
+    function bar() { ... }
+}
+
    + + +
      +
    • pro.ast_mangle(ast, options) – generates a new AST containing mangled + (compressed) variable and function names. It supports the following + options: + +
        +
      • toplevel – mangle toplevel names (by default we don't touch them). +
        • +
      • except – an array of names to exclude from compression. +
        • +
      • defines – an object with properties named after symbols to + replace (see the --define option for the script) and the values + representing the AST replacement value. + +
        • +
      + +
      • +
    • pro.ast_squeeze(ast, options) – employs further optimizations designed + to reduce the size of the code that gen_code would generate from the + AST. Returns a new AST. options can be a hash; the supported options + are: + +
        +
      • make_seqs (default true) which will cause consecutive statements in a + block to be merged using the "sequence" (comma) operator + +
        • +
      • dead_code (default true) which will remove unreachable code. + +
        • +
      + +
      • +
    • pro.gen_code(ast, options) – generates JS code from the AST. By + default it's minified, but using the options argument you can get nicely + formatted output. options is, well, optional :-) and if you pass it it + must be an object and supports the following properties (below you can see + the default values): + +
        +
      • beautify: false – pass true if you want indented output +
        • +
      • indent_start: 0 (only applies when beautify is true) – initial + indentation in spaces +
        • +
      • indent_level: 4 (only applies when beautify is true) -- + indentation level, in spaces (pass an even number) +
        • +
      • quote_keys: false – if you pass true it will quote all keys in + literal objects +
        • +
      • space_colon: false (only applies when beautify is true) – wether + to put a space before the colon in object literals +
        • +
      • ascii_only: false – pass true if you want to encode non-ASCII + characters as \uXXXX. +
        • +
      • inline_script: false – pass true to escape occurrences of + </script in strings +
        • +
      + +
      • +
    + + +
    + +
    + +
    +

    1.4.2 Beautifier shortcoming – no more comments

    +
    + + +

    +The beautifier can be used as a general purpose indentation tool. It's +useful when you want to make a minified file readable. One limitation, +though, is that it discards all comments, so you don't really want to use it +to reformat your code, unless you don't have, or don't care about, comments. +

    +

    +In fact it's not the beautifier who discards comments — they are dumped at +the parsing stage, when we build the initial AST. Comments don't really +make sense in the AST, and while we could add nodes for them, it would be +inconvenient because we'd have to add special rules to ignore them at all +the processing stages. +

    +
    + +
    + +
    +

    1.4.3 Use as a code pre-processor

    +
    + + +

    +The --define option can be used, particularly when combined with the +constant folding logic, as a form of pre-processor to enable or remove +particular constructions, such as might be used for instrumenting +development code, or to produce variations aimed at a specific +platform. +

    +

    +The code below illustrates the way this can be done, and how the +symbol replacement is performed. +

    + + + +
    CLAUSE1: if (typeof DEVMODE === 'undefined') {
+    DEVMODE = true;
+}
+
+CLAUSE2: function init() {
+    if (DEVMODE) {
+        console.log("init() called");
+    }
+    ....
+    DEVMODE &amp;&amp; console.log("init() complete");
+}
+
+CLAUSE3: function reportDeviceStatus(device) {
+    var DEVMODE = device.mode, DEVNAME = device.name;
+    if (DEVMODE === 'open') {
+        ....
+    }
+}
+
    + + +

    +When the above code is normally executed, the undeclared global +variable DEVMODE will be assigned the value true (see CLAUSE1) +and so the init() function (CLAUSE2) will write messages to the +console log when executed, but in CLAUSE3 a locally declared +variable will mask access to the DEVMODE global symbol. +

    +

    +If the above code is processed by UglifyJS with an argument of +--define DEVMODE=false then UglifyJS will replace DEVMODE with the +boolean constant value false within CLAUSE1 and CLAUSE2, but it +will leave CLAUSE3 as it stands because there DEVMODE resolves to +a validly declared variable. +

    +

    +And more so, the constant-folding features of UglifyJS will recognise +that the if condition of CLAUSE1 is thus always false, and so will +remove the test and body of CLAUSE1 altogether (including the +otherwise slightly problematical statement false = true; which it +will have formed by replacing DEVMODE in the body). Similarly, +within CLAUSE2 both calls to console.log() will be removed +altogether. +

    +

    +In this way you can mimic, to a limited degree, the functionality of +the C/C++ pre-processor to enable or completely remove blocks +depending on how certain symbols are defined - perhaps using UglifyJS +to generate different versions of source aimed at different +environments +

    +

    +It is recommmended (but not made mandatory) that symbols designed for +this purpose are given names consisting of UPPER_CASE_LETTERS to +distinguish them from other (normal) symbols and avoid the sort of +clash that CLAUSE3 above illustrates. +

    +
    +
    + +
    + +
    +

    1.5 Compression – how good is it?

    +
    + + +

    +Here are updated statistics. (I also updated my Google Closure and YUI +installations). +

    +

    +We're still a lot better than YUI in terms of compression, though slightly +slower. We're still a lot faster than Closure, and compression after gzip +is comparable. +

    + +
    +

    1.6 Bugs?

    +
    + + +

    +Unfortunately, for the time being there is no automated test suite. But I +ran the compressor manually on non-trivial code, and then I tested that the +generated code works as expected. A few hundred times. +

    +

    +DynarchLIB was started in times when there was no good JS minifier. +Therefore I was quite religious about trying to write short code manually, +and as such DL contains a lot of syntactic hacks1 such as “foo == bar ? a += 10 : b = 20â€, though the more readable version would clearly be to use +“if/elseâ€. +

    +

    +Since the parser/compressor runs fine on DL and jQuery, I'm quite confident +that it's solid enough for production use. If you can identify any bugs, +I'd love to hear about them (use the Google Group or email me directly). +

It is developed on [[http://nodejs.org/][NodeJS]], but it +should work on any JavaScript platform supporting the CommonJS module system +(and if your platform of choice doesn't support CommonJS, you can easily +implement it, or discard the =exports.*= lines from UglifyJS sources). + +The tokenizer/parser generates an abstract syntax tree from JS code. You +can then traverse the AST to learn more about the code, or do various +manipulations on it. This part is implemented in [[../lib/parse-js.js][parse-js.js]] and it's a +port to JavaScript of the excellent [[http://marijn.haverbeke.nl/parse-js/][parse-js]] Common Lisp library from [[http://marijn.haverbeke.nl/][Marijn +Haverbeke]]. + +( See [[http://github.com/mishoo/cl-uglify-js][cl-uglify-js]] if you're looking for the Common Lisp version of +UglifyJS. ) + +The second part of this package, implemented in [[../lib/process.js][process.js]], inspects and +manipulates the AST generated by the parser to provide the following: + +- ability to re-generate JavaScript code from the AST. Optionally + indented---you can use this if you want to “beautify†a program that has + been compressed, so that you can inspect the source. But you can also run + our code generator to print out an AST without any whitespace, so you + achieve compression as well. + +- shorten variable names (usually to single characters). Our mangler will + analyze the code and generate proper variable names, depending on scope + and usage, and is smart enough to deal with globals defined elsewhere, or + with =eval()= calls or =with{}= statements.

    UglifyJS – a JavaScript parser/compressor/beautifier

    \n\n\n\n\n
    \n

    1 UglifyJS — a JavaScript parser/compressor/beautifier

    \n
    \n\n\n

    \nThis package implements a general-purpose JavaScript\nparser/compressor/beautifier toolkit. It is developed on NodeJS, but it\nshould work on any JavaScript platform supporting the CommonJS module system\n(and if your platform of choice doesn't support CommonJS, you can easily\nimplement it, or discard the exports.* lines from UglifyJS sources).\n

    \n

    \nThe tokenizer/parser generates an abstract syntax tree from JS code. You\ncan then traverse the AST to learn more about the code, or do various\nmanipulations on it. This part is implemented in parse-js.js and it's a\nport to JavaScript of the excellent parse-js Common Lisp library from Marijn Haverbeke.\n

    \n

    \n( See cl-uglify-js if you're looking for the Common Lisp version of\nUglifyJS. )\n

    \n

    \nThe second part of this package, implemented in process.js, inspects and\nmanipulates the AST generated by the parser to provide the following:\n

    \n
      \n
    • ability to re-generate JavaScript code from the AST. Optionally\n indented—you can use this if you want to “beautify†a program that has\n been compressed, so that you can inspect the source. But you can also run\n our code generator to print out an AST without any whitespace, so you\n achieve compression as well.\n\n
      • \n
    • shorten variable names (usually to single characters). Our mangler will\n analyze the code and generate proper variable names, depending on scope\n and usage, and is smart enough to deal with globals defined elsewhere, or\n with eval() calls or with{} statements. In short, if eval() or\n with{} are used in some scope, then all variables in that scope and any\n variables in the parent scopes will remain unmangled, and any references\n to such variables remain unmangled as well.\n\n
      • \n
    • various small optimizations that may lead to faster code but certainly\n lead to smaller code. Where possible, we do the following:\n\n
        \n
      • foo[\"bar\"] ==> foo.bar\n\n
        • \n
      • remove block brackets {}\n\n
        • \n
      • join consecutive var declarations:\n var a = 10; var b = 20; ==> var a=10,b=20;\n\n
        • \n
      • resolve simple constant expressions: 1 +2 * 3 ==> 7. We only do the\n replacement if the result occupies less bytes; for example 1/3 would\n translate to 0.333333333333, so in this case we don't replace it.\n\n
        • \n
      • consecutive statements in blocks are merged into a sequence; in many\n cases, this leaves blocks with a single statement, so then we can remove\n the block brackets.\n\n
        • \n
      • various optimizations for IF statements:\n\n
          \n
        • if (foo) bar(); else baz(); ==> foo?bar():baz();\n
          • \n
        • if (!foo) bar(); else baz(); ==> foo?baz():bar();\n
          • \n
        • if (foo) bar(); ==> foo&&bar();\n
          • \n
        • if (!foo) bar(); ==> foo||bar();\n
          • \n
        • if (foo) return bar(); else return baz(); ==> return foo?bar():baz();\n
          • \n
        • if (foo) return bar(); else something(); ==> {if(foo)return bar();something()}\n\n
          • \n
        \n\n
        • \n
      • remove some unreachable code and warn about it (code that follows a\n return, throw, break or continue statement, except\n function/variable declarations).\n\n
        • \n
      • act a limited version of a pre-processor (c.f. the pre-processor of\n C/C++) to allow you to safely replace selected global symbols with\n specified values. When combined with the optimisations above this can\n make UglifyJS operate slightly more like a compilation process, in\n that when certain symbols are replaced by constant values, entire code\n blocks may be optimised away as unreachable.\n

    1.1 Unsafe transformations

    \n
    \n\n\n

    \nThe following transformations can in theory break code, although they're\nprobably safe in most practical cases. To enable them you need to pass the\n--unsafe flag.\n

    \n\n
    \n\n
    \n

    1.1.1 Calls involving the global Array constructor

    \n
    \n\n\n

    \nThe following transformations occur:\n

    \n\n\n\n
    new Array(1, 2, 3, 4)  => [1,2,3,4]\nArray(a, b, c)         => [a,b,c]\nnew Array(5)           => Array(5)\nnew Array(a)           => Array(a)\n
    \n\n\n

    \nThese are all safe if the Array name isn't redefined. JavaScript does allow\none to globally redefine Array (and pretty much everything, in fact) but I\npersonally don't see why would anyone do that.\n

    \n

    \nUglifyJS does handle the case where Array is redefined locally, or even\nglobally but with a function or var declaration. Therefore, in the\nfollowing cases UglifyJS doesn't touch calls or instantiations of Array:\n

    \n\n\n\n
    // case 1.  globally declared variable\n  var Array;\n  new Array(1, 2, 3);\n  Array(a, b);\n\n  // or (can be declared later)\n  new Array(1, 2, 3);\n  var Array;\n\n  // or (can be a function)\n  new Array(1, 2, 3);\n  function Array() { ... }\n\n// case 2.  declared in a function\n  (function(){\n    a = new Array(1, 2, 3);\n    b = Array(5, 6);\n    var Array;\n  })();\n\n  // or\n  (function(Array){\n    return Array(5, 6, 7);\n  })();\n\n  // or\n  (function(){\n    return new Array(1, 2, 3, 4);\n    function Array() { ... }\n  })();\n\n  // etc.\n
    \n\n\n
    \n\n
    \n\n
    \n

    1.1.2 obj.toString() ==> obj+“â€

    \n\n
    \n

    1.4 Usage

    \n
    \n\n\n

    \nThere is a command-line tool that exposes the functionality of this library\nfor your shell-scripting needs:\n

    \n\n\n\n
    uglifyjs [ options... ] [ filename ]\n
    \n\n\n

    \nfilename should be the last argument and should name the file from which\nto read the JavaScript code. If you don't specify it, it will read code\nfrom STDIN.\n

    \n

    \nSupported options:\n

    \n
      \n
    • -b or --beautify — output indented code; when passed, additional\n options control the beautifier:\n\n
        \n
      • -i N or --indent N — indentation level (number of spaces)\n\n
        • \n
      • -q or --quote-keys — quote keys in literal objects (by default,\n only keys that cannot be identifier names will be quotes).\n\n
        • \n
      \n\n
      • \n
    • --ascii — pass this argument to encode non-ASCII characters as\n \\uXXXX sequences. By default UglifyJS won't bother to do it and will\n output Unicode characters instead. (the output is always encoded in UTF8,\n but if you pass this option you'll only get ASCII).\n\n
      • \n
    • -nm or --no-mangle — don't mangle names.\n\n
      • \n
    • -nmf or --no-mangle-functions – in case you want to mangle variable\n names, but not touch function names.\n\n
      • \n
    • -ns or --no-squeeze — don't call ast_squeeze() (which does various\n optimizations that result in smaller, less readable code).\n\n
      • \n
    • -mt or --mangle-toplevel — mangle names in the toplevel scope too\n (by default we don't do this).\n\n
      • \n
    • --no-seqs — when ast_squeeze() is called (thus, unless you pass\n --no-squeeze) it will reduce consecutive statements in blocks into a\n sequence. For example, \"a = 10; b = 20; foo();\" will be written as\n \"a=10,b=20,foo();\". In various occasions, this allows us to discard the\n block brackets (since the block becomes a single statement). This is ON\n by default because it seems safe and saves a few hundred bytes on some\n libs that I tested it on, but pass --no-seqs to disable it.\n\n
      • \n
    • --no-dead-code — by default, UglifyJS will remove code that is\n obviously unreachable (code that follows a return, throw, break or\n continue statement and is not a function/variable declaration). Pass\n this option to disable this optimization.\n\n
      • \n
    • -nc or --no-copyright — by default, uglifyjs will keep the initial\n comment tokens in the generated code (assumed to be copyright information\n etc.). If you pass this it will discard it.\n\n
      • \n
    • -o filename or --output filename — put the result in filename. If\n this isn't given, the result goes to standard output (or see next one).\n\n
      • \n
    • --overwrite — if the code is read from a file (not from STDIN) and you\n pass --overwrite then the output will be written in the same file.\n\n
      • \n
    • --ast — pass this if you want to get the Abstract Syntax Tree instead\n of JavaScript as output. Useful for debugging or learning more about the\n internals.\n\n
      • \n
    • -v or --verbose — output some notes on STDERR (for now just how long\n each operation takes).\n\n
      • \n
    • -d SYMBOL[=VALUE] or --define SYMBOL[=VALUE] — will replace\n all instances of the specified symbol where used as an identifier\n (except where symbol has properly declared by a var declaration or\n use as function parameter or similar) with the specified value. This\n argument may be specified multiple times to define multiple\n symbols - if no value is specified the symbol will be replaced with\n the value true, or you can specify a numeric value (such as\n 1024), a quoted string value (such as =\"object\"= or\n ='https://github.com'), or the name of another symbol or keyword (such as =null or document).\n This allows you, for example, to assign meaningful names to key\n constant values but discard the symbolic names in the uglified\n version for brevity/efficiency, or when used wth care, allows\n UglifyJS to operate as a form of conditional compilation\n whereby defining appropriate values may, by dint of the constant\n folding and dead code removal features above, remove entire\n superfluous code blocks (e.g. completely remove instrumentation or\n trace code for production use).\n Where string values are being defined, the handling of quotes are\n likely to be subject to the specifics of your command shell\n environment, so you may need to experiment with quoting styles\n depending on your platform, or you may find the option\n --define-from-module more suitable for use.\n\n
      • \n
    • -define-from-module SOMEMODULE — will load the named module (as\n per the NodeJS require() function) and iterate all the exported\n properties of the module defining them as symbol names to be defined\n (as if by the --define option) per the name of each property\n (i.e. without the module name prefix) and given the value of the\n property. This is a much easier way to handle and document groups of\n symbols to be defined rather than a large number of --define\n options.\n\n
      • \n
    • --unsafe — enable other additional optimizations that are known to be\n unsafe in some contrived situations, but could still be generally useful.\n For now only these:\n\n
        \n
      • foo.toString() ==> foo+\"\"\n
        • \n
      • new Array(x,…) ==> [x,…]\n
        • \n
      • new Array(x) ==> Array(x)\n\n
        • \n
      \n\n
      • \n
    • --max-line-len (default 32K characters) — add a newline after around\n 32K characters. I've seen both FF and Chrome croak when all the code was\n on a single line of around 670K. Pass –max-line-len 0 to disable this\n safety feature.\n\n
      • \n
    • --reserved-names — some libraries rely on certain names to be used, as\n pointed out in issue #92 and #81, so this option allow you to exclude such\n names from the mangler. For example, to keep names require and $super\n intact you'd specify –reserved-names \"require,$super\".\n\n
      • \n
    • --inline-script – when you want to include the output literally in an\n HTML <script> tag you can use this option to prevent </script from\n showing up in the output.\n\n
      • \n
    • --lift-vars – when you pass this, UglifyJS will apply the following\n transformations (see the notes in API, ast_lift_variables):\n\n
        \n
      • put all var declarations at the start of the scope\n
        • \n
      • make sure a variable is declared only once\n
        • \n
      • discard unused function arguments\n
        • \n
      • discard unused inner (named) functions\n
        • \n
      • finally, try to merge assignments into that one var declaration, if\n possible.\n

    1.4.1 API

    \n
    \n\n\n

    \nTo use the library from JavaScript, you'd do the following (example for\nNodeJS):\n

    \n\n\n\n
    var jsp = require(\"uglify-js\").parser;\nvar pro = require(\"uglify-js\").uglify;\n\nvar orig_code = \"... JS code here\";\nvar ast = jsp.parse(orig_code); // parse code and get the initial AST\nast = pro.ast_mangle(ast); // get a new AST with mangled names\nast = pro.ast_squeeze(ast); // get an AST with compression optimizations\nvar final_code = pro.gen_code(ast); // compressed code here\n
    \n\n\n

    \nThe above performs the full compression that is possible right now. As you\ncan see, there are a sequence of steps which you can apply. For example if\nyou want compressed output but for some reason you don't want to mangle\nvariable names, you would simply skip the line that calls\npro.ast_mangle(ast).\n

    \n

    \nSome of these functions take optional arguments. Here's a description:\n

    \n
      \n
    • jsp.parse(code, strict_semicolons) – parses JS code and returns an AST.\n strict_semicolons is optional and defaults to false. If you pass\n true then the parser will throw an error when it expects a semicolon and\n it doesn't find it. For most JS code you don't want that, but it's useful\n if you want to strictly sanitize your code.\n\n
      • \n
    • pro.ast_lift_variables(ast) – merge and move var declarations to the\n scop of the scope; discard unused function arguments or variables; discard\n unused (named) inner functions. It also tries to merge assignments\n following the var declaration into it.\n\n

      \n If your code is very hand-optimized concerning var declarations, this\n lifting variable declarations might actually increase size. For me it\n helps out. On jQuery it adds 865 bytes (243 after gzip). YMMV. Also\n note that (since it's not enabled by default) this operation isn't yet\n heavily tested (please report if you find issues!).\n

      \n Note that although it might increase the image size (on jQuery it gains\n 865 bytes, 243 after gzip) it's technically more correct: in certain\n situations, dead code removal might drop variable declarations, which\n would not happen if the variables are lifted in advance.\n

      \n

      \n Here's an example of what it does:\n

      • \n
    \n\n\n\n\n\n
    function f(a, b, c, d, e) {\n    var q;\n    var w;\n    w = 10;\n    q = 20;\n    for (var i = 1; i < 10; ++i) {\n        var boo = foo(a);\n    }\n    for (var i = 0; i < 1; ++i) {\n        var boo = bar(c);\n    }\n    function foo(){ ... }\n    function bar(){ ... }\n    function baz(){ ... }\n}\n\n// transforms into ==>\n\nfunction f(a, b, c) {\n    var i, boo, w = 10, q = 20;\n    for (i = 1; i < 10; ++i) {\n        boo = foo(a);\n    }\n    for (i = 0; i < 1; ++i) {\n        boo = bar(c);\n    }\n    function foo() { ... }\n    function bar() { ... }\n}\n

    • pro.ast_mangle(ast, options) – generates a new AST containing mangled\n (compressed) variable and function names. It supports the following\n options:\n\n
        \n
      • toplevel – mangle toplevel names (by default we don't touch them).\n
        • \n
      • except – an array of names to exclude from compression.\n

        \n
      • beautify: false – pass true if you want indented output\n
        • \n

        • \n
      • indent_level: 4 (only applies when beautify is true) --\n indentation level, in spaces (pass an even number)\n
        • \n

        • \n
      • space_colon: false (only applies when beautify is true) – wether\n to put a space before the colon in object literals\n
        • \n
      • ascii_only: false – pass true if you want to encode non-ASCII\n characters as \\uXXXX.\n

    1.4.2 Beautifier shortcoming – no more comments

    \n
    \n\n\n

    \nThe beautifier can be used as a general purpose indentation tool. It's\nuseful when you want to make a minified file readable. One limitation,\nthough, is that it discards all comments, so you don't really want to use it\nto reformat your code, unless you don't have, or don't care about, comments.\n

    \n

    \nIn fact it's not the beautifier who discards comments — they are dumped at\nthe parsing stage, when we build the initial AST. Comments don't really\nmake sense in the AST, and while we could add nodes for them, it would be\ninconvenient because we'd have to add special rules to ignore them at all\nthe processing stages.\n

    \n
    \n\n
    \n\n
    \n

    1.4.3 Use as a code pre-processor

    \n
    \n\n\n

    \nThe --define option can be used, particularly when combined with the\nconstant folding logic, as a form of pre-processor to enable or remove\nparticular constructions, such as might be used for instrumenting\ndevelopment code, or to produce variations aimed at a specific\nplatform.\n

    \n

    \nThe code below illustrates the way this can be done, and how the\nsymbol replacement is performed.\n

    \n\n\n\n
    CLAUSE1: if (typeof DEVMODE === 'undefined') {\n    DEVMODE = true;\n}\n\nCLAUSE2: function init() {\n    if (DEVMODE) {\n        console.log(\"init() called\");\n    }\n    ....\n    DEVMODE &amp;&amp; console.log(\"init() complete\");\n}\n\nCLAUSE3: function reportDeviceStatus(device) {\n    var DEVMODE = device.mode, DEVNAME = device.name;\n    if (DEVMODE === 'open') {\n        ....\n    }\n}\n
    \n\n\n

    \nWhen the above code is normally executed, the undeclared global\nvariable DEVMODE will be assigned the value true (see CLAUSE1)\nand so the init() function (CLAUSE2) will write messages to the\nconsole log when executed, but in CLAUSE3 a locally declared\nvariable will mask access to the DEVMODE global symbol.\n

    \n

    \nIf the above code is processed by UglifyJS with an argument of\n--define DEVMODE=false then UglifyJS will replace DEVMODE with the\nboolean constant value false within CLAUSE1 and CLAUSE2, but it\nwill leave CLAUSE3 as it stands because there DEVMODE resolves to\na validly declared variable.\n

    \n

    \nAnd more so, the constant-folding features of UglifyJS will recognise\nthat the if condition of CLAUSE1 is thus always false, and so will\nremove the test and body of CLAUSE1 altogether (including the\notherwise slightly problematical statement false = true; which it\nwill have formed by replacing DEVMODE in the body). Similarly,\nwithin CLAUSE2 both calls to console.log() will be removed\naltogether.\n

    \n

    \nIn this way you can mimic, to a limited degree, the functionality of\nthe C/C++ pre-processor to enable or completely remove blocks\ndepending on how certain symbols are defined - perhaps using UglifyJS\nto generate different versions of source aimed at different\nenvironments\n

    \n

    \nIt is recommmended (but not made mandatory) that symbols designed for\nthis purpose are given names consisting of UPPER_CASE_LETTERS to\ndistinguish them from other (normal) symbols and avoid the sort of\nclash that CLAUSE3 above illustrates.\n

    1.5 Compression – how good is it?

    \n
    \n\n\n

    \nHere are updated statistics. (I also updated my Google Closure and YUI\ninstallations).\n

    \n

    \nWe're still a lot better than YUI in terms of compression, though slightly\nslower. We're still a lot faster than Closure, and compression after gzip\nis comparable.\n

    1.6 Bugs?

    \n
    \n\n\n

    \nUnfortunately, for the time being there is no automated test suite. But I\nran the compressor manually on non-trivial code, and then I tested that the\ngenerated code works as expected. A few hundred times.\n

    \n

    \nDynarchLIB was started in times when there was no good JS minifier.\nTherefore I was quite religious about trying to write short code manually,\nand as such DL contains a lot of syntactic hacks1 such as “foo == bar ? a\n= 10 : b = 20â€, though the more readable version would clearly be to use\n“if/elseâ€.\n

    \n

    \nSince the parser/compressor runs fine on DL and jQuery, I'm quite confident\nthat it's solid enough for production use. If you can identify any bugs,\nI'd love to hear about them (use the Google Group or email me directly).\n

    Contours

    + +Contours levels can be overlaid on the displayed image. + +

    +The N entry box controls the number of contours levels to draw. + +

    +Pressing the Draw Contours button will draw contours at the image levels +currently listed in the Levels: list. + +

    +Pressing the Set Min/Max button will fill in the min and max entry boxes +from the minimum and maximum values of the image. + +

    +Pressing the Make Levels will fill in the levels list with an evenly +spaced list of level values from min to max excluding the min and max values +themselves. + +

    +The Binning option allows the image data to be binned before +the contours are computed. Contours will be computed more quickly for +binned images. However, binning will cause the positions of the contours +to be less accurate. + +

    +The Smooth option causes the image data to be smoothed by a Gaussian kernel +with the specified sigma number of pixels before the contours are computed. +This technique often is necessary to achieve good results for sparse data +(e.g. event files). However, it can affect the accuracy of the contours. + +

    +The Quality radio button chooses between one of two contouring methods. +The faster option selects contours with up to 4 points per pixel. The quality +option selects contours with up to 8 points to pixel. + + + diff --git a/plugins/imexam/encircled.js b/plugins/imexam/encircled.js new file mode 100644 index 00000000..77a5b356 --- /dev/null +++ b/plugins/imexam/encircled.js @@ -0,0 +1,69 @@ +/*jslint white: true, vars: true, plusplus: true, nomen: true, unparam: true */ +/*globals $, JS9 */ + +"use strict"; + + +(function() { + var imexam = require("./imexam"); + + var encen_template = " \ +

    Region Statistics

    + +A rectangular box of image pixels is selected and some statical values +are computed from the data. The selected box may be rotated for box and +ellipse regions. + +

    +N.B.: Currently the region shape is ignored and the values reflect a rectangular section of image pixels. +

    + +

    +

    Notes

    + +
      +
    • Background and Noise +

      + The background and noise are obtained from the outer 4 pixel-wide + perimeter of the selected region. The background value is the median + value of this area and the noise value is the RMS. +

      • +
    • Centroid +

      + The centroid is obtained by locating the brightest 9 pixel box and + computing the centroid of the background subtracted data about this point. +

      • +
    • FWHM +

      + The FWHM is estimated from the image moments about the centroid, assuming + a Gaussian distribution. +

      • +
    + +

    + +

    X and Y Projection Plot

    + +A rectangular box of image pixels is selected and the projection along the +region's X or Y axis is plotted. The sum, average or median of the projected +pixels may be selected. The selected box may be rotated for box and ellipse +regions. + + +

    + +

    Radial Profile

    + +A rectangular box of image pixels is selected and the pixels values are +plotted against their respective radii. A Gaussian is fit to the radial profile +data and the result is also plotted. The fitted results of the 4 parameter fit +are displayed with the plot. The selected box may be rotated for box and +ellipse regions. + +

    +The center pixel from which the radii are computed is determined from the +background subtracted centroid taken about the brightest 9 pixels in the data +(same centroid as is displayed in the region stats plugin). + + +

    + +

    Pixel Value Histogram

    + +A rectangular box of image pixels is selected and a histogram of the values +is plotted. The selected box may be rotated for box and +ellipse regions. + +The selected pixels are binned into 250 bins between the minimum and maximum value +found in the selected region. + +

    + +

    Encircled Energy

    + +A rectangular box of image pixels is selected and background subtracted. The +analysis radius is determined from the region as follows: + +
      +
    • circle: region radius
      • +
    • annulus: max annulus radius
      • +
    • box: half the average height an width
      • +
    • ellipse: average axis radius
      • +
    • polygon: half the average of the height and width of polygon bounding box
      • +
    + +The values within the analysis radius are binned in 1 pixel radial bins. The +bins are normalized by the sum of all pixels and the result is plotted. + +

    +The background is obtained as the median from the outer 4 pixel wide perimeter of the +selected region. + +

    +The center pixel from which the encircled energy is computed is determined from +the background subtracted centroid taken about the brightest 9 pixels in the +data (same centroid as is displayed in the region stats plugin). + +

    +The 50 and 80 percent encircled energy points are displayed over the plot. + +

    + +
