A closely-related use case is customizing the message displayed by error(), which is normally the usage string followed by the error message. I wanted to append instructions on how to invoke --help, and implemented it this way for CPython's regrtest: http://hg.python.org/cpython/file/6ee721029fd5/Lib/test/regrtest.py#l205 Also take a look at how regrtest formats its usage string as another use case to satisfy: http://hg.python.org/cpython/file/6ee721029fd5/Lib/test/regrtest.py#l9 It seems like many argparse customizations take the form of "override this method." Would it make sense for the API to be for customizers to override string-returning methods like make_usage() and make_error() (and that accept a dictionary)? That may give a bit more control than a format string. ---------- nosy: +chris.jerdonek _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11695> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
