[New-bugs-announce] [issue11174] add argparse formatting option to display type names for metavar

[Steven Bethard]

New submission from Steven Bethard <steven.bethard at gmail.com>:

Suggestion from a personal email:

I generally like my command line arguments that take a
value to specify the type, e.g.,

   --runs int      how many runs to do

Naturally I can do this using the metavars argument in every
add_argument() call, but that can become tedious. So I suggest adding a
metavars argument to the ArgumentParser constructor; default
metavars=None (current behaviour); metavars=type (show type names). And
of course, allow metavars specified in add_argument() calls to override
on a case by case basis.
