[issue10728] argparse.ArgumentParser.print_help uses sys.stdout
Jan-Philip Gehrcke added the comment: The version action currently writes to stderr. The _VersionAction(Action)'s __call__() method finishes off with parser.exit(message=formatter.format_help()) and parser.exit() by default writes to stderr. Here, Steven says Help is definitely intended to print to stdout. and I expected the same to happen regarding the version information. Why should it go to stderr? I see that this is a minor problem and only if someone here agrees I would open an issue for that. -- nosy: +jgehrcke ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10728 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10728] argparse.ArgumentParser.print_help uses sys.stdout
New submission from Silvio Ricardo Cordeiro silvioricar...@gmail.com: The documentation at http://docs.python.org/dev/library/argparse.html explicitly says that If file is None, sys.stderr is assumed. However, both print_usage and print_help assume sys.stdout when file=None. The helper method _print_message actually does it right, when called with file=None. -- components: Library (Lib) messages: 124271 nosy: silvioricardoc priority: normal severity: normal status: open title: argparse.ArgumentParser.print_help uses sys.stdout type: behavior versions: Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10728 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10728] argparse.ArgumentParser.print_help uses sys.stdout
R. David Murray rdmur...@bitdance.com added the comment: I think this is a documentation bug, since IMO help should print on stdout, not stderr[1]. I would expect print_usage to do likewise, but for the error to tell print_usage to write to stderr when it calls it...which is exactly what the code does. [1] I know some unix commands print help to stderr, and this really annoys me when I pipe long help output to lessand it *still* scrolls off the screen. -- assignee: - d...@python components: +Documentation -Library (Lib) nosy: +bethard, d...@python, r.david.murray stage: - needs patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10728 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
