New submission from ThatXliner <bryan.hu.2...@gmail.com>:
In argparse, I've always wanted a way to make colored help text like those of
poetry and pipenv. But argparse's show help isn't well documented (Therefore, I
can't find a way to completely modify the help text), and the metavar arg isn't
really helpful. I want to do something like this:
>>> import argparse
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument("foo", help="To foo a bar", display="FOO!!!!")
>>> parser.print_help()
usage: main.py [-h] foo
positional arguments:
FOO!!!! To foo a bar
optional arguments:
-h, --help show this help message and exit
>>>
That way, I can colorize the help output.
