PyObjC version 0.8 is now available for download. See... http://pyobjc.sourceforge.net/ ... for more information. The installer package includes a Project Builder project template for easily creating new Cocoa-Python projects and a slew of examples. Alternatively, the developer can choose to develop applications without using Apple's developer tools. Full support for Interface Builder documents is included. The PyObjC Python module provides a feature complete bridge between the Python programming language and Objective-C. With PyObjC, it is possible to transparently message Objective-C objects from Python and Python objects from Objective-C. Objective-C objects can be subclassed from within Python. Support is also included for using the various functions, enumerated types, and global variables found throughout the Objective-C framework. References to python dictionaries pass into Objective-C act like a well behaved member of the NSDictionary class cluster. Likewise, Python List references behave like a member of the NSArray class cluster. Strings are transparently converted to the native type. NSArray and NSDictionary references passed into Python behave like native Python lists and dictionaries; including the ability to enumerate either using the 'in' operator and to slice NSArray and NSMutableArray instances. PyObjC fully supports creating full featured Cocoa applications written in pure Python. There are aspects of PyObjC that are more powerful than Cocoa in pure Obj-C (the ability to automatically define classes/outlets based on the contents of a NIB file, for example). PyObjC requires OS X 10.2 or greater. 10.1 support is possible and will likely happen soon-- contact me if you need 10.1 support and are willing to do a bit of grunt work to generate the appropriate files (easy to do-- just need a 10.1 development machine). The installer package is designed to work with the built-in Python provided in OS X 10.2. Source is included on the disk image and the pyobjc module works with Python 2.2 or greater as installed directly from the Python Source, with the MacPython packages, and with the Fink build of python. PyObjC also provides an awesome environment for exploring frameworks. The following transcript was copied out of a Terminal window-- it is an example of working directly with the Objective-C runtime from Python within the terminal.
<PBXBuildStyle:0x00a77d30:011ADBA3FF9FD52E11CA0C5D:name='Development':bu ildSettings.count=2>, <PBXBuildStyle:0x00a82180:011ADBA4FF9FD52E11CA0C5D:name='Deployment':bui ldSettings.count=1> ) The version # of 0.8 indicates that documentation is lacking, unit tests are incomplete and there may be a bug or two lurking within. In practice, the module has proven to be very stable and to allow for the development of extremely complex Cocoa projects in pure Python or a mix of Python and Objective-C.
