If you're using the sources from CVS you should first download a copy of
libffi from the PyObjC download site. Extract this in a convenient location
and update the variable LIBFF_SOURCES at the top of setup.py. The released
version of PyObjC includes a compatible version of libffi.
PyObjC is build and installed using the distutils package included with Python
2.0 and beyond. This package provides a single interface for building and
packaging the module. To see usage documentation for the module,
issue the --help command:
% python setup.py --help
To see an inventory of building and packaging commands, issue the command:
% python setup.py --help-commands
The following command will build and install the pyobjc module:
% python setup.py install
The setup.py system can also be used to create source and binary distribution archives automatically.
Use sudo to install the pyobjc module into a the Apple supplied
python's site-packages directory on OS X 10.2 and greater:
% sudo python setup.py install
If you have multiple versions of python installed on your system, the above will only install pyobjc for whatever version of python is the default on the command line. Make sure you are installing python against the correct version of python.
To be able to build the wrappers for the WebKit framework (included with Safari 1.0), you'll have to install the WebKit SDK. You can download this from the ADC website.
The examples directory contains a number of projects that demonstrate various features of the PyObjC bridge. The scripts at the top level of the examples directory were mostly written to test a particular feature of the bridge (or document a bug until a fix could be found).
CurrencyConverter and TableModel are both examples of standalone Cocoa-Python applications. To build and execute:
% cd TableModel % python buildapp.py build
The WebServicesTool is an example of Cocoa-Python applications created via
the Cocoa-Python project template found in the
ProjectBuilder Extras/Project Templates directory. Use Project Builder
to build the applications.
The ProjectBuilder Extras directory contains additional files that can
be used with Project Builder. The directory Specifications contains files
that enable syntax coloring for Python files in Project Builder.
The Project Templates directory contains project templates for
Project Builder. These have to be copied to
/Developer/ProjectBuilder Extras/Project Templates/Application before
they are useable from Project Builder.
There are three templates available:
A project created from this template is designed to implement standalone, pure-Python, applications that are compatible with Apple's build of Python as well as all other builds of python that support PyObjC.
When building the 'install' target, the resulting application wrapper will included the PyObjC module and can be launched on any stock OS X 10.2 system without requiring PyObjC to be preinstalled.
A project created from this template includes an embedded framework project into which all compiled (Objective-C) code can be placed. Upon launch, the application automatically dynamically loads the embedded framework containing the compiled code.
Each Framework's Resources directory is automatically added to sys.path.
This template works like the Cocoa-Python Application template in that it is compatible with the Apple build of Python. It creates an application that uses Cocoa's Multiple Document Architecture in the same fashion as the default Cocoa Document-based Application supplied with Project Builder.
More information on project templates can be found in the Project Builder documentation and/or release notes.
