Description
argparse
supports short options, single-dash long options and double-dash long options. Values for option can be specified as separate argument (for all types of options):
--option value -option value -o value
It can also be grouped in a single argument with the option. In this case it should be separated by =
from the option name:
--option=value -option=value -ovalue
argparse
also supports abbreviation of long options (enabled by default):
--opt value -opt value
Abbreviated double-dash long options can be used with =
:
--opt=value
But this does not work with single-dash long options:
-opt=value
This is definitely an omission. There are other bugs related to abbreviation (#104860) and use with =
(#124305). There were many other bugs related to this code. This code is just not well tested.
The code for --opt=value
is not tested as well -- breaking it does not break tests.
