Getting Started
---------------
These instructions will guide you how to compile install and run the project
on your local machine for system-wide installation as well as for development
and testing purposes.


Automated installer for Debian based systems
--------------------------------------------
https://github.com/ltspicer/dxf2gcode.linux.installer


Prerequisites
-------------

- Unix machines:
  - Build dependencies:
    - /usr/bin/python3 and development package (>=3.5),
    - PyQt5     (>=5.7),
    - PyOpenGL  (>=3.1),
    - configobj (>=5.0.6).
    - py2app    (>=0.14 only on macOS),
    - /usr/bin/lrelease-qt5 or /usr/bin/lrelease5 or /usr/bin/lrelease,
    - /usr/bin/pylupdate5,
    - /usr/bin/pyuic5,

    - PyQt5             (>=5.7),
    - PyOpenGL          (>=3.1),
    - configobj         (>=5.0.6),
    - /usr/bin/pdftops  (>=0.45),
    - /usr/bin/pstoedit (>=3.70).

    Note: Depending you used operating system flavour different package names
    might provides required dependencies. Please use package manager to retrieve
    those names (e.g. on Fedora Linux use: $ dnf provides /usr/bin/python3).

- Windows machine
  - Build dependencies:
    - python3     (>=3.6.2),
    - setuptools  (>=28.8.0),
    - sip         (>=4.19.3),
    - pip         (>=9.0.1),
    - PyQt5       (>=5.9),
    - PyOpenGL    (>=3.1),
    - pyqt5-tools (>=5.9.0.1.2),
    - cx-Freeze   (>=5.0.2),
    - configobj   (>=5.0.6).

    Python 3 should be installed from: https://www.python.org/downloads/,
    during installation pip package should be selected to be installed.
    Using pip remaining python dependencies might be installed using:

    C:\> pip3 install sip PyQt5 PyOpenGL pyqt5-tools cx-Freeze configobj


  - Runtime dependencies:
    - python3   (>=3.6.2),
    - PyQt5     (>=5.9),
    - PyOpenGL  (>=3.1),
    - configobj (>=5.0.6),
    - pdftops   (>=4.00) [http://www.xpdfreader.com/download.html] (Xpdf-tools package),
    - pstoedit  (>=3.70) [https://sourceforge.net/projects/pstoedit/],
    - gswin32c  (>=9.09) [https://sourceforge.net/projects/ghostscript/].

    Note: if gswin32c is not on the PATH then -gs option needs to be added to
    pstoedit tool in Options->Configuration->Software config->pstoedit
    e.g.: -gs, C:/Program Files (x86)/gs/gs9.09/bin/gswin32c.exe
    (above assumes v9.09 and default path installation).

    Note(2): pstoedit needs C++ runtime libraries if you don't have it please search for:
    "Microsoft Visual C++ 2010 Redistributable Package (x64)" and install it.
    It is recommended to run both pdftops and pstoedit from command line (CMD)
    to verify the installation correctness.


Building and Installing
-----------------------
  - Unix (assumes bash shell):
    $ ./make_tr.py     # generates .qm translation files in i18 directory
    $ ./make_py_uic.py # generates: dxf2gcode_ui5.py and dxf2gcode_images.qrc
    $ python3 ./st-setup.py build
    # python3 ./st-setup.py install
    $ dxf2gcode

    Note(1): depending on used desktop environment you might need to run:
    # /bin/touch --no-create /usr/share/icons/hicolor
    and/or re-login to make application’s shortcut appears in the system menu.

    Note(2): On Fedora Linux distribution (version >=26) dxf2gode can be
    installed directly either by using: dnf install dxf2gcode or from
    your preferred graphical package manager (e.g. GNOME Software)
    (see also: https://src.fedoraproject.org/rpms/dxf2gcode).
    Development versions of dxf2gcode (from develop branch) are available
    in: https://copr.fedorainfracloud.org/coprs/dwrobel/dxf2gcode/

  - Windows (assumes python.exe v3 is on PATH):
    python.exe ./make_tr.py
    python.exe ./make_py_uic.py
    python.exe setup.py bdist_msi
    Install DXF2GCODE-<version>-win32.msi (located in dist sub-directory).
    Launch it from Start Menu by typing: dxf2gcode

  - macOS:
    Note(1): It is recommended to install python dependencies using 'pip' tool.
    $ ./make_tr.py
        If 'lrelease' is not on the PATH use something like the following:
        $ PATH=$PATH:/usr/local/Cellar/qt/5.11.1/bin ./make_tr.py
    $ ./make_py_uic.py
    $ ./st-setup.py py2app # builds standalone application

    To launch application use either:
        $ open dist/dxf2gcode.app
    or
        $ ./dist/dxf2gcode.app/Contents/MacOS/dxf2gcode

    It is still untested but in order to build dxf2gcode.pkg use the following:
    $ productbuild  --component dist/dxf2gcode.app /Applications dist/dxf2gcode.pkg


Configuration
-------------
  - Unix, Windows:
    Basic configuration requires verification of location of pdftops and
    pstoedit executables in menu Options->Configuration-Software config.

  - Configuration files are stored on all platforms at the following directory:
        ~/.config/dxf2gcode

    Alternatively the following python code can be used to determine it as well:
        import os; print(os.path.join(os.path.expanduser("~"),
        ".config/dxf2gcode").replace("\\", "/"))

  - Additional information can be found in the projects' wiki page at:
    https://sourceforge.net/p/dxf2gcode/wiki/Home/


Development
-----------

  - Development:
    For development/debugging purposes you may run the program directly from
    the source code directory by typing (depending on operating system):
      - Unix: $ python3 ./dxf2gcode.py
      - Windows: python.exe ./dxf2gcode.py

  - Tests:
    It is recommended to check if program can successfully convert all DXF
    files from the dxf directory. In order to do that please run from the
    source code directory dxf2gcode_test.py test as following:
      - Unix: $ python3 ./dxf2gcode_test.py
      - Windows: python.exe ./dxf2gcode_test.py

  - New releases:
    - Source tarball (for both Unix and Windows) can be prepared by running:
    $ python3 ./st-setup.py sdist --formats=zip

  - Binary packages (installers) can be prepared either directly from checked
    out sources from git repository or based on previously generated source
    tarballs (see above: "Building and Installing" - build part).

Translations
------------

  DXF2GCODE uses Qt's built-in translation mechanism.
  As such, you will need the usual Qt tools to work on translations
  (lrelease, linguist and pylupdate5 from PyQt5 instead of Qt's lupdate,
  because the later doesn't speak Python).

  To do translation work, run 'make trs' first. This will prepare the
  .ts files in i18n/ to be edited with 'linguist'. Then you may run
  'linguist' on the .ts files you're interested in, and translate what
  you intend. After that, please run 'make trf' again, this will remove
  <location> tags from the .ts files which are a constant source of
  merge conflicts (and blows up the diffs). Finally, do a commit and
  submit it to upstream.
