Message401115
This is has been requested various times on StackOverflow, and possibly here (I'd have to do a search).
The closest thing to making a compact action_invocation is to set the metavar to '', and even thing we get a space, eg.
-f , --foo Help text
This repeat has been a part of argparse from the beginning, so I can't see changing the default behavior. But we could add a HelpFormatter subclass that changes one (or two methods) such as _format_action_invocation. Subclassing the formatter is the accepted way of adding help features. I, and possibly others, must have suggested such a change on SO.
Of course people can use such a subclass without it being part of the standard module. |
