Fixes a bug where pygettext would attempt to extract a message from a code like this: def _(x): pass This is because pygettext only looks at one token at a time and '_(x)' looks like a function call. However, since 'x' is not a string literal, it would erroneously issue a warning. This commit fixes that by keeping track of the previous token and checking if it's 'def' or 'class'.

There's no other file that uses this encoding, I think it's safe (and more practical) to use utf-8.

Got it! I'll revert :) Would you accept a separate (perhaps not backported) PR that removes the coding and the commented-out code or do you think it's not worth it?

I'll accept it if there are pygettext tests for files with non-UTF-8 encoding.

Fair enough, I'll add it to my todo list :)

The new logic is, if we see one of the gettext keywords and the previous token is not def or class, only then we transition to __keywordseen.

Note that no warnings are emitted if option --docstrings is used. I think that we can use a similar approach. We can add
if ttype == tokenize.NAME and tstring in ('class', 'def'):
self.__state = self.__ignorenext
return
where __ignorenext simply sets self.__state = self.__waiting.
