[issue26967] argparse: allow_abbrev=False stops -vv from working

paul j3 added the comment: Someone needs to take the current argparse.py, set the default value of this parameter to False, and run the unittest file. This should turn up this case, and possibly others that fail when abbreviations are turned off. Then we have to debate whether such failures

paul j3 added the comment: It's been 2 years since I worked on this patch. In the issue discussion http://bugs.python.org/issue14910 there was no mention of short v long options. The unit tests only look at longs. The result is that with the abbrev off, it disables all use of combined shorts

Xiang Zhang added the comment: I agree with you. But right now, it seems parsing short options and allow_abbrev both rely on the same logic. If you turn off allow_abbrev, short options parsing also disabled. Separating them seems nontrivial. -- ___

Michael Kruse added the comment: I think the allow_abbrev option should be orthogonal on how short options are parsed. I am using parse_known_args() to forward the unrecognized args to another program, therefore allow_abbrev=False is essential. There is a special handling for short options in

Xiang Zhang added the comment: After some research I suggest to document this behaviour that allow_abbrev=False will suspend option prefix matching. Simply fixing the count action behaviour is not enough since it also prevents you from creating custom actions that want to use option prefix mat

Xiang Zhang added the comment: This is a side effect introduced by 99302634d756. You have to set allow_abbrev to True to make such match succeed. I think this is a bug. -- ___ Python tracker __
