From: Michele Simionato on 20 Jun 2010 05:22 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

How about adding some support for internationalization of the generated usage output? Andre

The usage message of plac is actually generated by the underlying argparse library. argparse use gettext internally, so I would say the support is already there.

I've seen several scripts following the format basescript command [options] subcommands [other optiones] ... It would be great if one can compose functions to form the commands. Instead of def main(command, opt1, opt2): """...""" if command == 'cmd1': ... elif command == 'cmd2': ... if __name__=='__main__': import plac plac.call(main) one could then write def cmd1(opt1): """...""" ... def cmd2(opt2): """...""" ... if __name__=='__main__': import plac plac.call(plac.commands(cmd1, cmd2)) This should then produce usage info like this $ basescript --help usage: basescript [-h] command .... commands: cmd1 cmd2 $ basescript cmd1 --help usage basescript cmd1 [cmd1 specific options] .... $ basescript cmd2 --help usage basescript cmd2 [cmd2 specific options] .... Maybe one could even extend to subcommands and so on. Maybe this is already possible but just not covered by the first link I've read by now. Anyway, I very much like this package and it seems like I have a new friend at my disposal. Thanks and best regards Andre

The good one is http://micheles.googlecode.com/hg/plac/doc/plac_adv.html. Luckily the one I posted on PyPI is correct. ><snip> > Maybe one could even extend to subcommands and so on. > Maybe this is already possible but just not covered by the first link > I've read by now. Indeed this is already possible and covered in the advanced document. See the section containers of commands: http://micheles.googlecode.com/hg/plac/doc/plac_adv.html#containers-of-commands |
