How can I check .mo file validity?

Question

I'm using PHP to make .mo files out of the database and have run into a strange problem: some keys work, some don't. I think there is some kind of a problem with the generated files. How can I check, whether a .mo file is correct?

Answer 1

Use msgunfmt, which is the opposite of msgfmt:

msgunfmt something.mo

If the .mo file is messed up, msgunfmt will complain.

Answer 2

polib can open and read .mo files; it should not be difficult to create a small tool that iterates through the entries, allowing you to verify them.
