New submission from Reuben Thomas <r...@sc3d.org>:
The documentation seems very clear on this subject: "RawTextHelpFormatter maintains whitespace for all sorts of help text, including argument descriptions. However, multiple new lines are replaced with one." But consider the following code: ``` from argparse import ArgumentParser, RawDescriptionHelpFormatter parser = ArgumentParser( description='A simple templating system.', epilog='Use `-\' as a file name to indicate standard input or output.', formatter_class=RawDescriptionHelpFormatter, ) parser.add_argument( '--verbose', help='show on standard error the path being built,\nand the names of files built, included and pasted' ) args = parser.parse_args() ``` Then try running it in a suitably-sized terminal: $ python3 test.py --help usage: test.py [-h] [--verbose VERBOSE] A simple templating system. optional arguments: -h, --help show this help message and exit --verbose VERBOSE show on standard error the path being built, and the names of files built, included and pasted Use `-' as a file name to indicate standard input or output. ``` The \n in the help for the `--verbose` argument is not respected. ---------- components: Library (Lib) messages: 391890 nosy: rrt priority: normal severity: normal status: open title: RawDescriptionHelpFormatter seems to be ignored for argument descriptions versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43942> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
