The PyObjC project aims to provide a bridge between the Python and Objective-C programming languages. The bridge is intended to be fully bidirectional, allowing the Python programmer to take full advantage of the power provided by various Objective-C based toolkits and the Objective-C programmer transparent access to Python based functionality.

The most important usage of this is writing Cocoa GUI applications on Mac OS X in pure Python. See our tutorial for an example of this.

News

2009-05-26: PyObjC 2.2b2 released -

PyObjC 2.2b2 is the second beta release for PyObjC 2.2. There are relatively few user-visibly changes from the last release.

This release can be installed using easy_install

Usage:

$ easy_install pyobjc==2.2b2

This will install the core bridge as well as all stable framework wrappers.

NOTE: This is a beta release, which means there are still know issues with this release although it should in general be stable and an improvement over the last release.

NOTE2: easy_install will not install py2app, you will have to install that manually.

2009-03-01: PyObjC 2.2b1 released -

PyObjC 2.2b1 is the first beta release for PyObjC 2.2. There are relatively few user-visibly changes from the last release. The most important ones are:

  • This release can be installed using easy_install

    Usage:

    $ easy_install pyobjc==2.2b1
    

    This will install the core bridge as well as all stable framework wrappers.

  • Most framework wrappers ship with unittests that verify that the wrappers actually work as intended.

    These tests are not yet entirely complete, but have already helped in finding and fixing a number of issues.

NOTE: This is a beta release, which means there are still know issues with this release although it should in general be stable and an improvement over the last release.

NOTE2: easy_install will not install py2app, you will have to install that manually.

2008-05-27: A short status update -

PyObjC development is pretty slow at the moment. I had hoped to release PyObjC 2.1 in March, but that was not to be.

The trunk is slowly moving forward though, but (still) doesn't support OSX 10.4 at the moment. Fixing that is easy, but takes time.

2008-01-07: Updated website -

The website has been updated with documentation and examples from PyObjC 2.0.

It is now possible to download examples and view source code in a nice format.

2008-01-06: PyObjC 2.0 included in MacOSX Leopard -

Mac OS X 10.5 (Leopard) contains many new features, one of which is a new major release of PyObjC: PyObjC 2.0.

The NEWS file provides the best overview of new features, the following list is a small overview:

  • The package pyobjc is split into several smaller packages, this will make future updates easier.
  • PyObjC now supports the bridgesupport metadata format, which makes it easier to support new frameworks without having to write C code. The same metadata format is also used by RubyCocoa.
  • Class methods are modelled better, allowing one have a class method and instance method with the same name ( which is used in several occassions in the Cocoa frameworks).
   

Status

PyObjC 2.2b2 was released on May 26th 2009. See the NEWS file for details.

PyObjC supports Mac OS X 10.3.9 and later, earlier versions are not supported.
