py2app is a Python setuptools command which will allow
you to make standalone Mac OS X application bundles
and plugins from Python scripts.

py2app is similar in purpose and design to py2exe for
Windows.

py2app 0.5.1
------------

py2app 0.5.1 is a bugfix release

Bug fixes:

- Ensure stub executables get included in the egg files

- Fix name of the bundletemplate stub executable for 32-bit builds



py2app 0.5
----------

py2app 0.5 is a minor feature release.

Features:
- Add support for the ``--with-framework-name`` option of Python's
  configure script, that is: py2app now also works when the Python
  framework is not named 'Python.framework'.
- Add support for various build flavours of Python (32bit, 3-way, ...)
- py2app now actually works for me (ronaldoussoren@mac.com) with a 
  python interpreter in a virtualenv environment.
- Experimental support for python 3

Bug fixes:
- Fix recipe for matplotlib: that recipe caused an exception with
  current versions of matplotlib and pytz.
- Use modern API's in the alias-build bootstrap code, without
  this 'py2app -A' will result in broken bundles on a 64-bit build
  of Python. 
  (Patch contributed by James R Eagan)
- Try both 'import Image' and 'from PIL import Image' in the PIL
  recipe.
  (Patch contributed by Christopher Barker)
- The stub executable now works for 64-bit application bundles
- (Lowlevel) The application stub was rewritten to use
  ``dlopen`` instead of ``dyld`` APIs. This removes deprecation
  warnings during compilation.

py2app 0.4.3
------------

py2app 0.4.3 is a bugfix release

Bug fixes:
- A bad format string in build_app.py made it impossible to copy the
  Python framework into an app bundle.

py2app 0.4.2
------------

py2app 0.4.2 is a minor feature release

Features:

- When the '--strip' option is specified we now also remove '.dSYM' 
  directories from the bundle.

- Remove dependency on a 'version.plist' file in the python framework

- A new recipe for `PyQt`_ 4.x. This recipe was donated by Kevin Walzer.

- A new recipe for `virtualenv`_, this allows you to use py2app from 
  a virtual environment.

- Adds support for converting ``.xib`` files (NIB files for
  Interface Builder 3)

- Introduces an experimental plugin API for data converters. 

  A conversion plugin should be defined as an entry-point in the
  ``py2app.converter`` group::

       setup(
         ...
	 entry_points = {
		 'py2app.converter': [
		     "label          = some_module:converter_function",
		  ]
	  },
	  ...
      )

  The conversion function should be defined like this::

      from py2app.decorators import converts

      @converts('.png')
      def optimze_png(source, proposed_destionation, dryrun=0):
         # Copy 'source' to 'proposed_destination'
	 # The conversion is allowed to change the proposed
	 # destination to another name in the same directory.
         pass

.. `virtualenv`_: http://pypi.python.org/pypi/virtualenv

Buf fixes:

- This fixes an issue with copying a different version of Python over 
  to an app/plugin bundle than the one used to run py2app with.


py2app 0.4.0
------------

py2app 0.4.0 is a minor feature release (and was never formally released).

Features:
- Support for CoreData mapping models (introduced in Mac OS X 10.5)
- Support for python packages that are stored in zipfiles (such as ``zip_safe``
  python eggs). 

Bug fixes:
- Fix incorrect symlink target creation with an alias bundle that has included
  frameworks.
- Stuffit tends to extract archives recursively, which results in unzipped
  code archives inside py2app-created bundles. This version has a workaround
  for this "feature" for Stuffit.
- Be more carefull about passing non-constant strings as the template argumenti
  of string formatting functions (in the app and bundle templates), to avoid
  crashes under some conditions.

py2app 0.3.6
------------

py2app 0.3.6 is a minor bugfix release.

Bug fixes:

- Ensure that custom icons are copied into the output bundle
- Solve compatibility problem with some haxies and inputmanager plugins


py2app 0.3.5
------------

py2app 0.3.5 is a minor bugfix release.

Bug fixes:

- Resolve disable_linecache issue
- Fix Info.plist and Python path for plugins


py2app 0.3.4
------------

py2app 0.3.4 is a minor bugfix release.

Bug fixes:

- Fixed a typo in the py2applet script
- Removed some, but not all, compiler warnings from the bundle template
  (which is still probably broken anyway)


py2app 0.3.3
------------

py2app 0.3.3 is a minor bugfix release.

Bug Fixes:

- Fixed a typo in the argv emulation code
- Removed the unnecessary py2app.install hack (setuptools does that already)


py2app 0.3.2
------------

py2app 0.3.2 is a major bugfix release.

Functional changes:

- Massively updated documentation
- New prefer-ppc option
- New recipes: numpy, scipy, matplotlib
- Updated py2applet script to take options, provide --make-setup

Bug Fixes:

- No longer defaults to LSPrefersPPC
- Replaced stdlib usage of argvemulator to inline version for i386
  compatibility


py2app 0.3.1
------------

py2app 0.3.1 is a minor bugfix release.

Functional changes:

- New EggInstaller example

Bug Fixes:

- Now ensures that the executable is +x (when installed from egg this may not
  be the case)


py2app 0.3.0
------------

py2app 0.3.0 is a major feature enhancements release.

Functional changes:

- New --xref (-x) option similar to py2exe's that produces
  a list of modules and their interdependencies as a HTML
  file
- sys.executable now points to a regular Python interpreter
  alongside the regular executable, so spawning sub-interpreters
  should work much more reliably
- Application bootstrap now detects paths containing ":"
  and will provide a "friendly" error message instead of just
  crashing <http://python.org/sf/1507224>.
- Application bootstrap now sets PYTHONHOME instead of
  a large PYTHONPATH
- Application bootstrap rewritten in C that links to
  CoreFoundation and Cocoa dynamically as needed,
  so it doesn't imply any particular version of the runtime.
- Documentation and examples changed to use setuptools
  instead of distutils.core, which removes the need for
  the py2app import
- Refactored to use setuptools, distributed as an egg.
- macholib, bdist_mpkg, modulegraph, and altgraph are now
  separately maintained packages available on PyPI as eggs
- macholib now supports little endian architectures,
  64-bit Mach-O headers, and reading/writing of
  multiple headers per file (fat / universal binaries)


py2app 0.2.1
------------

py2app 0.2.1 is a minor bug fix release.

Bug Fixes:

- macholib.util.in_system_path understands SDKs now
- DYLD_LIBRARY_PATH searching is fixed
- Frameworks and excludes options should work again.


py2app 0.2.0
------------

py2app 0.2.0 is a minor bug fix release.

Functional changes:

- New datamodels option to support CoreData.  Compiles
  .xcdatamodel files and places them in the Resources dir
  (as .mom).

- New use-pythonpath option.  The py2app application bootstrap
  will no longer use entries from PYTHONPATH unless this option
  is used.

- py2app now persists information about the build environment
  (python version, executable, build style, etc.) in the
  Info.plist and will clean the executable before rebuilding
  if anything at all has changed.

- bdist_mpkg now builds packages with the full platform info,
  so that installing a package for one platform combination
  will not look like an upgrade to another platform combination.

Bug Fixes:

- Fixed a bug in standalone building, where a rebuild could
  cause an unlaunchable executable.

- Plugin bootstrap should compile/link correctly
  with gcc 4.

- Plugin bootstrap no longer sets PYTHONHOME and will
  restore PYTHONPATH after initialization.

- Plugin bootstrap swaps out thread state upon plug-in
  load if it is the first to initialize Python.  This
  fixes threading issues.

py2app 0.1.9
------------

py2app 0.1.9 is a minor bug fix release.

Bugs fixed:

- bdist_mpkg now builds zip files that are correctly unzipped
  by all known tools.

- The behavior of the bootstrap has changed slightly such that
  ``__file__`` should now point to your main script, rather than
  the bootstrap.  The main script has also moved to ``Resources``,
  from ``Resources/Python``, so that ``__file__`` relative resource
  paths should still work.

py2app 0.1.8
------------

py2app 0.1.8 is a major enhancements release:

Bugs fixed:

- Symlinks in included frameworks should be preserved correctly
  (fixes Tcl/Tk)
- Fixes some minor issues with alias bundles
- Removed implicit SpiderImagePlugin -> ImageTk reference in PIL
  recipe
- The ``--optimize`` option should work now
- ``weakref`` is now included by default
- ``anydbm``'s dynamic dependencies are now in the standard implies
  list
- Errors on app launch are brought to the front so the user does
  not miss them
- bdist_mpkg now compatible with pychecker (data_files had issues)

Options changed:

- deprecated ``--strip``, it is now on by default
- new ``--no-strip`` option to turn off stripping of executables

New features:

- Looks for a hacked version of the PyOpenGL __init__.py so that
  it doesn't have to include the whole package in order to get
  at the stupid version file.
- New ``loader_files`` key that a recipe can return in order to
  ensure that non-code ends up in the .zip (the pygame recipe
  uses this)
- Now scans all files in the bundle and normalizes Mach-O load
  commands, not just extensions.  This helps out when using the
  ``--package`` option, when including frameworks that have plugins,
  etc.
- An embedded Python interpreter is now included in the executable
  bundle (``sys.executable`` points to it), this currently only 
  works for framework builds of Python
- New ``macho_standalone`` tool
- New ``macho_find`` tool
- Major enhancements to the way plugins are built
- bdist_mpkg now has a ``--zipdist`` option to build zip files
  from the built package
- The bdist_mpkg "Installed to:" description is now based on the
  package install root, rather than the build root

py2app 0.1.7
------------

`py2app`_ 0.1.7 is a bug fix release:

- The ``bdist_mpkg`` script will now set up sys.path properly, for setup scripts
  that require local imports.
- ``bdist_mpkg`` will now correctly accept ``ReadMe``, ``License``, ``Welcome``,
  and ``background`` files by parameter.
- ``bdist_mpkg`` can now display a custom background again (0.1.6 broke this).
- ``bdist_mpkg`` now accepts a ``build-base=`` argument, to put build files in
  an alternate location.
- ``py2app`` will now accept main scripts with a ``.pyw`` extension.
- ``py2app``'s not_stdlib_filter will now ignore a ``site-python`` directory as
  well as ``site-packages``.
- ``py2app``'s plugin bundle template no longer displays GUI dialogs by default,
  but still links to ``AppKit``.
- ``py2app`` now ensures that the directory of the main script is now added to
  ``sys.path`` when scanning modules.
- The ``py2app`` build command has been refactored such that it would be easier
  to change its behavior by subclassing.
- ``py2app`` alias bundles can now cope with editors that do atomic saves
  (write new file, swap names with existing file).
- ``macholib`` now has minimal support for fat binaries.  It still assumes big
  endian and will not make any changes to a little endian header.
- Add a warning message when using the ``install`` command rather than installing
  from a package.
- New ``simple/structured`` example that shows how you could package an
  application that is organized into several folders.
- New ``PyObjC/pbplugin`` Xcode Plug-In example.

py2app 0.1.6
------------

Since I have been slacking and the last announcement was for 0.1.4, here are the 
changes for the soft-launched releases 0.1.5 and 0.1.6:

`py2app`_ 0.1.6 was a major feature enhancements release:

- ``py2applet`` and ``bdist_mpkg`` scripts have been moved to Python modules
  so that the functionality can be shared with the tools.
- Generic graph-related functionality from ``py2app`` was moved to
  ``altgraph.ObjectGraph`` and ``altgraph.GraphUtil``.
- ``bdist_mpkg`` now outputs more specific plist requirements
  (for future compatibility).
- ``py2app`` can now create plugin bundles (MH_BUNDLE) as well as executables.
  New recipe for supporting extensions built with `sip`_, such as `PyQt`_.  Note that
  due to the way that `sip`_ works, when one sip-based extension is used, *all*
  sip-based extensions are included in your application.  In practice, this means
  anything provided by `Riverbank`_, I don't think anyone else uses `sip`_ (publicly).
- New recipe for `PyOpenGL`_.  This is very naive and simply includes the whole
  thing, rather than trying to monkeypatch their brain-dead
  version acquisition routine in ``__init__``.
- Bootstrap now sets ``ARGVZERO`` and ``EXECUTABLEPATH`` environment variables,
  corresponding to the ``argv[0]`` and the ``_NSGetExecutablePath(...)`` that the
  bundle saw.  This is only really useful if you need to relaunch your own
  application.
- More correct ``dyld`` search behavior.
- Refactored ``macholib`` to use ``altgraph``, can now generate `GraphViz`_ graphs
  and more complex analysis of dependencies can be done.
- ``macholib`` was refactored to be easier to maintain, and the structure handling
  has been optimized a bit.
- The few tests that there are were refactored in `py.test`_ style.
- New `PyQt`_ example.
- New `PyOpenGL`_ example.

py2app 0.1.5
------------

`py2app`_ 0.1.5 is a major feature enhancements release:

- Added a ``bdist_mpkg`` distutils extension, for creating Installer 
  an metapackage from any distutils script.

  - Includes PackageInstaller tool
  - bdist_mpkg script
  - setup.py enhancements to support bdist_mpkg functionality

- Added a ``PackageInstaller`` tool, a droplet that performs the same function
    as the ``bdist_mpkg`` script.
- Create a custom ``bdist_mpkg`` subclass for `py2app`_'s setup script.
- Source package now includes `PJE`_'s `setuptools`_ extension to distutils.
- Added lots of metadata to the setup script.
- ``py2app.modulegraph`` is now a top-level package, ``modulegraph``.
- ``py2app.find_modules`` is now ``modulegraph.find_modules``.
- Should now correctly handle paths (and application names) with unicode characters
  in them.
- New ``--strip`` option for ``py2app`` build command, strips all Mach-O files 
  in output application bundle.
- New ``--bdist-base=`` option for ``py2app`` build command, allows an alternate
  build directory to be specified.
- New `docutils`_ recipe.
  Support for non-framework Python, such as the one provided by `DarwinPorts`_.

py2app 0.1.4
------------

`py2app`_ 0.1.4 is a minor bugfix release:

- The ``altgraph`` from 0.1.3 had a pretty nasty bug in it that prevented 
  filtering from working properly, so I fixed it and bumped to 0.1.4.

py2app 0.1.3
------------

`py2app`_ 0.1.3 is a refactoring and new features release:

- ``altgraph``, my fork of Istvan Albert's `graphlib`_, is now part of the
  distribution
- ``py2app.modulegraph`` has been refactored to use ``altgraph``
- `py2app`_ can now create `GraphViz`_ DOT graphs with the ``-g`` option
  (`TinyTinyEdit example`_)
- Moved the filter stack into ``py2app.modulegraph``
- Fixed a bug that may have been in 0.1.2 where explicitly included packages
  would not be scanned by ``macholib``
- ``py2app.apptemplate`` now contains a stripped down ``site`` module as 
  opposed to a ``sitecustomize``
- Alias builds are now the only ones that contain the system and user 
  ``site-packages`` directory in ``sys.path``
- The ``pydoc`` recipe has been beefed up to also exclude ``BaseHTTPServer``,
  etc.

Known issues:

- Commands marked with XXX in the help are not implemented
- Includes *all* files from packages, it should be smart enough to strip
  unused .py/.pyc/.pyo files (to save space, depending on which optimization
  flag is used)
- ``macholib`` should be refactored to use ``altgraph``
- ``py2app.build_app`` and ``py2app.modulegraph`` should be refactored to
  search for dependencies on a per-application basis

.. _`TinyTinyEdit example`: http://undefined.org/~bob/TinyTinyEdit.pdf

py2app 0.1.2
------------

`py2app`_ 0.2 is primarily a bugfix release:

- The encodings package now gets included in the zip file (saves space)
- A copy of the Python interpreter is not included anymore in standalone
  builds (saves space)
- The executable bootstrap is now stripped by default (saves a little space)
- ``sys.argv`` is set correctly now, it used to point to the executable, now
  it points to the boot script.  This should enhance compatibility with some
  applications.
- Adds an "Alias" feature to modulegraph, so that ``sys.modules`` craziness
  such as ``wxPython.wx -> wx`` can be accomodated (this particular craziness
  is also now handled by default)
- A ``sys.path`` alternative may be passed to ``find_modules`` now, though
  this is not used yet
- The ``Command`` instance is now passed to recipes instead of the
  ``Distribution`` instance (though no recipes currently use either)
- The post-filtering of modules and extensions is now generalized into a 
  stack and can be modified by recipes
- A `wxPython`_ example demonstrating how to package `wxGlade`_ has been 
  added (this is a good example of how to write your own recipe, and how to
  deal with complex applications that mix code and data files)
- ``PyRuntimeLocations`` is now set to (only) the location of the current
  interpreter's ``Python.framework`` for alias and semi-standalone build 
  modes (enhances compatibility with extensions built with an unpatched
  Makefile with Mac OS X 10.3's Python 2.3.0)

Known issues:

- Includes *all* files from packages, it should be smart enough to strip
  unused .py/.pyc/.pyo files (to save space, depending on which optimization
  flag is used).

.. _`wxGlade`: http://wxglade.sourceforge.net/

py2app 0.1.1
------------

`py2app`_ 0.1.1 is primarily a bugfix release:

- Several problems related to Mac OS X 10.2 compatibility and standalone 
   building have been resolved
- Scripts that are not in the same directory as setup.py now work
- A new recipe has been added that removes the pydoc -> Tkinter dependency
- A recipe has been added for `py2app`_ itself
- a `wxPython`_ example (superdoodle) has been added.  
  Demonstrates not only how easy it is (finally!) to bundle 
  `wxPython`_ applications, but also how one setup.py can 
  deal with both `py2exe`_ and `py2app`_.
- A new experimental tool, py2applet, has been added.  
  Once you've built it (``python setup.py py2app``, of course), you should
  be able to build simple applications simply by dragging your main script
  and optionally any packages, data files, Info.plist and icon it needs.

Known issues:

- Includes *all* files from packages, it should be smart enough to strip
  unused .py/.pyc/.pyo files (to save space, depending on which 
  optimization flag is used).

- The default ``PyRuntimeLocations`` can cause problems on machines that
  have a /Library/Frameworks/Python.framework installed.  Workaround is
  to set a plist that has the following key: 
  ``PyRuntimeLocations=['/System/Library/Frameworks/Python.framework/Versions/2.3/Python']``
  (this will be resolved soon)


py2app 0.1
----------

(first public release)
`py2app`_ is the bundlebuilder replacement we've all been waiting
for.  It is implemented as a distutils command, similar to `py2exe`_.

.. _`wxPython`: http://www.wxpython.org/
.. _`py2app`: http://undefined.org/python/#py2app
.. _`py2exe`: http://starship.python.net/crew/theller/py2exe/
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
