on the action's default, reverting it back to previous behavior. Conversion
is only done on string defaults.
Add a test for this and another test that ensures such type conversions are
only called once.
This fixes a regression introduced by the fix for issue #13922. Although args
is not documented as being allowed to be a tuple, previously this worked and
so naturally there are programs in the field that depend on it.
Patch by Zbyszek Jędrzejewski-Szmek.
Before, the type function was called twice in the case where the default
was specified and the argument was given as well. This was especially
problematic for the FileType type, as a default file would always be
opened, even if a file argument was specified on the command line.
Patch by Arnaud Fontaine, with additional test by Mike Meyer.
An argparse option parser created with a prefix_chars that did not
include a '-' would happily add -h and --help options, and then throw
an error when it tried to format the help because the - was an invalid
prefix character. This patch makes it use the first character of
prefix_chars as the character for the help options if and only if '-'
is not one of the valid prefix_chars.
Fix by Theodore Turocy, unit tests by Catherine Devlin.
