I have forked a project on github and need to have a set of changes I made since I forked, in diff format.
If you wonder - I\'ve forked Apache httpd and I\'m changin
This is an old question, but I just found a very nice method to get a patch or diff file directly from Github.
When you are on your fork, there is a "Compare" link. Using that you are getting to the compare view.
Example
https://github.com/luisgoncalves/xades4j/compare/master...beat2:master
Now you can manually add either ".diff" or ".patch" to the end of this url, and you get the file directly in your browser.
Example
https://github.com/luisgoncalves/xades4j/compare/master...beat2:master.diff
