History of Changes

0.6.19

  • Allow both multiple groups and extensions to existing groups (follow up to #62).
  • Allow mutable attribute groups (#65). Unfortunately this breaks new AttributeGroup(...), which must be replaced with groupOf(...) or mutableGroupOf(...).
  • Simplified Kotlin DSL by introducing MutableAttributeGroup, which replaces InAttributeGroup.
  • Added format check to jprint (#66).

0.6.17

  • Pass orientation into PwgHeader (#59).
  • More flexible Kotlin DLS (#62).
  • Latest symbols from IANA listing.

0.6.16

  • Allow for more attribute groups in the IPP Packet DSL (#33).
  • Add better toString() output for AttributeTypes (#55).
  • Replace OutputSettings outputBin and stackingOrder with reversed (#56).

0.6.12

  • PCLM and PWG Raster got upgrades, in that they properly handle multi-page and duplex cases. You're only responsible for providing a normal, front-to-back RenderableDocument, and to pass along valid settings based on known printer attributes and user output requirements. The PDL library internally handles page re-ordering, page rotation, flipping, etc to provide the best possible output. As a result the PwgCapabilities and PclmCapabilties classes have been removed in favor of PwgSettings and PclmSettings.
  • Attribute.unknown etc was moved to Attributes.unknown for backwards-compatibility with Java.

0.6.6

  • The KeywordOrName type was introduced to allow for fields that can legitimately contain either IANA-registered keywords OR unregistered, locally-defined names. For example, MediaCol.mediaType must contain a KeywordOrName, not simply a String (Keyword).

Earlier versions

  • Types includes all defined types as published as of 2018-04-06 at IANA.
  • Collection types such as MediaCol are expressed as POJO and are automatically constructed/deconstructed.
  • com.hp.jipp.model.IppPacket moved to com.hp.jipp.encoding.IppPacket so that all PWG generated code lives in .model.
  • Keyword attribute values are present as simple, untyped Strings. Allowed strings are provided in static objects (e.g. Media.java defines all possible media types.)
  • The MediaSize type is removed in favor of Media strings. If needed, the MediaSizes utility class provides a method to extract x- and y-dimensions from a Media keyword containing dimensions.
  • The Attribute class is a List of attribute values, so it is no longer necessary to call .getValues() to obtain them.
  • The AttributeGroup class is a List of Attribute<*> so it may be iterated directly to access attributes it contains.
  • Attributes of Name or Text types appear in those types to allow clients to access language information if present and to distinguish from ordinary keywords. The following additional methods may help to convert attribute values to String:
    • Name.asString() and Text.asString() are Stringable and extract the value in string form. .getValue() also does this.
    • Attribute.strings(), AttributeGroup.getStrings(), and IppPacket.getStrings() do the same for all types.
  • Status.ok becomes Status.successfulOk, etc.
