• Issue: Add translation tests for getopt and optparse #126413

[tomasr8]

I'm looking into the test failures

[tomasr8]

Looks like pygettext is getting tripped up by this:

cpython/Lib/getopt.py

Line 41 in 865f096

def _(s): return s

This was removed by another PR of mine which was not backported: #126358 (which is why this did not fail on main)
Perhaps we could backport it to fix this issue for now? A more definitive fix would be to update pygettext to not get confused by def _(...)

@serhiy-storchaka What do you think?

[serhiy-storchaka]

I think that changing pygettext is more preferable. This will benefit not only us, but all users.

But if it is non-trivial, backporting #126358 is the second good option.

I agree that fixing this in pygettext is better, I'm gonna see if I can come up with a simple fix

[tomasr8]

I think I found a pretty simple fix, I'll send a PR tomorrow :)

CI's looking good now both here and on the 3.12 backport #126756 🙂 @serhiy-storchaka
