Entrian Solutions is pleased to announce version 1.0 of the 'goto' module. This adds the 'goto' and 'comefrom' keywords to Python 2.3, adding flexibility to Python's control flow mechanisms and allowing Python programmers to use many common control flow idioms that were previously denied to them. 'goto' example: breaking out from a deeply nested loop: from goto import goto, label for i in range(1, 10): for j in range(1, 20): for k in range(1, 30): print i, j, k if k == 3: goto .end label .end print "Finished\n" 'comefrom' example: letting cleanup code take control after an error. from goto import comefrom, label def bigFunction(): setUp() if not doFirstTask(): label .failed if not doSecondTask(): label .failed if not doThirdTask(): label .failed comefrom .failed cleanUp() Computed 'goto's are also supported - see the documentation for details. Computed 'comefrom's are planned for a future release. Documentation and further examples: http://entrian.com/goto/index.html Downloads: http://entrian.com/goto/download.html The 'goto' module is released under the Python Software Foundation license, and requires Python 2.3 or later. Please note that this version does not work at the interactive Python prompt - code importing 'goto' must be in a .py file. This restriction will hopefully be lifted in a future release. -- Richie Hindle richie@entrian.com
