New submission from Denilson Figueiredo de Sá <denilso...@gmail.com>:
In my script, I wanted two things at the same time: 1. Setting a formatter class so that the epilog would have the line breaks preserved. 2. Telling argparse to automatically display default values for all arguments. Currently, both things are handled by the same configuration parameter: formatter_class This means we can either pass argparse.RawDescriptionHelpFormatter or argparse.ArgumentDefaultsHelpFormatter, but not both. I did a hackish workaround by subclassing both formatters, and passing my (empty) subclass to ArgumentParser. It works for now, but it might break on future versions. The ideal solution, however, would have a native support for both features, or at least explicitly allowing subclassing. Maybe ArgumentDefaultsHelpFormatter could be transformed into a simple boolean parameter passed to ArgumentParser object (and maybe also passed to add_argument() method), instead of being a formatter class. ---------- components: Library (Lib) messages: 144354 nosy: denilsonsa priority: normal severity: normal status: open title: argparse should allow displaying argument default values in addition to setting a formatter class type: feature request versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13023> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
