A few weeks ago I presented on this list my most recent effort, plac. Now there is a *huge* new release: the size of plac and of its documentation doubled.
Now plac is much more than a simple command-line arguments parser: it is also a generic tool to write command languages, similar to the cmd module in the standard library, only better. In particular plac supports a doctests-like functionality for each language you define for it, as well as a plac runner to run your scripts and tests. You define plac commands from Python functions: plac will build a parser from the function signature and interpret the command line accordingly. The documentation contains a lot of simple and not so simple examples: http://micheles.googlecode.com/hg/plac/doc/plac.html http://micheles.googlecode.com/hg/plac/doc/plac_ext.html Plac works in all versions of Python starting from Python 2.3 up to Python 3.1, but the new features require Python 2.5. You can download it from PyPI ($ easy_install -U plac): http://pypi.python.org/pypi/plac Enjoy! Michele Simionato -- http://mail.python.org/mailman/listinfo/python-list
