Summary: gettext.py incompatible with eggs

Initial Comment:
If you distribute your code in a zipped egg, you can't use translation catalogs stored in that egg.  That's because gettext.py only knows how to find the translation catalogs in the actual filesystem.

This wouldn't be so bad if the "find" function didn't serve double duty.  On the one hand, it implements the "find" algorithm to pick the right languages and fallbacks.  On the other hand, it actually resolves the files in the filesystem.  It would be nice if these were separate.  It seems like people in projects like Pylons are stuck copying code from the find function in order to work around this problem.

Perhaps gettext can be updated to know about eggs.  Perhaps setting localedir to something like "egg://..." would enable this functionality.

Do you have a proposal on how to do the refactoring? It would be fine to
split find into two parts; it would not be acceptable (to me) to teach it
egg: URLs.

Sorry, yes, this is a feature request.  The most important thing that I'm
requesting is to refactor the code.  That "find" function implements a
certain algorithm that has nothing to do with the filesystem.

I fail to see the bug. gettext.find behaves as specified; if you want
something else, don't use that function.

If you want to load a .mo file from a zip file, you should be able to
create a GNUTranslation object directly, from a file-like object.

I don't think that gettext should support eggs directly. If you want it to
do things other than loading from file systems, you should generalize that
appropriately. One appropriate generalization could be the introduction of
a directory-like object, where you can do .exists(relpath), and
.open(relpath). However, introduction of directory-like objets is PEP
material.

Reclassifying this as a feature request.
