You can give us feedback - comments, critiques, suggestions, etc. Bug reports and feature requests are always welcome. Check out our forums and the bug tracker, or stop by for a chat in the IRC channel.

Spreading the word

Like Aegisub? Tell your friends about it! Spreading the word is a good way of helping Aegisub to be the best subtitle editor around.


Feeling generous? Consider giving us a donation! We do this in our spare time, you know.

Feel like really helping out, or do you just have some code you want to donate? Some advice from readme.txt in the source tree:

First, some of the code is pretty readable, some is decent, and some is patched up crap. Good luck. ;)

Before coding up a new feature you should probably hop on IRC and check with a developer to verify that we agree it's a feature that Aegisub should have, or you run the risk of wasting some work. Unsolicited bug fixes are usually welcome, though.

Second, if you want to code anything for Aegisub, you will need to agree to these terms:

  1. You will release the patch to the public domain or give its copyright to one of the developers. This is to stop a source file from being owned by too many people. (Exception: MAJOR changes might be accepted under BSD license under your name. Consult the developers)
  2. Make SURE it compiles and works fine before submitting to developers.
  3. Patches should normally be against git master, unless it's for a bug present in stable but not master.
  4. Pull requests should be rebased onto git master (or stable, if applicable), and you should have a topic branch per pull request. Please don't have any merge commits in your history.
  5. Aegisub doesn't have a single cohesive coding style, but do try to follow a style that's already present somewhere in the program (and preferable that of the code you're touching).

Third, this is all available under the BSD license. According to GNU itself, BSD is GPL-compatible, meaning that you can link GPL code to BSD code. Keep in mind, though, that if a source file has mixed BSD and GPL content, it becomes ruled by GPL.
