pyjamas - the stand-alone python-to-javascript compiler, and separate GUI Widget Toolkit, has its 0.7 release, today. this has been much delayed, in order to allow the community plenty of time between the 0.7pre2 release and the final release, to review and test all the examples. pyjamas allows developers to create applications that will run either in any modern web browser (with no plugins required) or as a stand-alone cross-platform desktop application (like PyQT4 or PyGTK2), WITHOUT requiring modifications to the original python source. this concept is singularly unique in the free software python world, but is conceptually similar to Adobe AIR and Silverlight - without the massive plugins required. there has been significant improvements, features and libraries added in between 0.6 and 0.7: please see the README in the distribution for details. for fits and giggles, to show what's possible in only 400 lines of python, here is a game of asteroids, written by joe rumsey. yes, it runs under pyjamas-desktop too. http://pyjs.org/examples/asteroids/public/Space.html For more information, see: http://pyjs.org http://pyjs.org/FAQ.html http://pyjs.org/features.html http://groups.google.com/group/pyjamas-dev downloads: http://pypi.python.org/pypi/Pyjamas http://code.google.com/p/pyjamas http://sf.net/projects/pyjamas known major bugs: http://code.google.com/p/pyjamas/issues #391 (google chrome beta) #384 (text selection on opera 10.51) contributions and investigations by community members to fix these and other issues welcomed and encouraged.
