Quickly find the GitHub pull request that merged your commit to master.
Ideally git blame would give you all the context you need to determine why some code was written. But the reality is that no team is perfectly disciplined, and sometimes you're going to run across commits with cryptic or ambiguous messages ("bugfix," anyone?).
When a git commit message doesn't provide enough context, or provides context at the wrong level (too much what, too little why), it's useful to be able to find the GitHub pull request that merged that commit. Pull requests can contain code review comments, discussion over implementation details, before/after pictures of the UI, and more. Pull requests may also have many commits associated with them, which together give a clearer sense of the intended change.
This utility allows you to find out which pull request merged a commit into master (assuming the commit came from a pull request—if it didn't, you're SOL!).
(Replace /usr/local/bin with a location on your path if /usr/local/bin is not on your $PATH.)
$ curl -o /usr/local/bin/git-getpull https://raw.githubusercontent.com/Genius/git-getpull/master/git-getpull && chmod +x /usr/local/bin/git-getpull$ git getpull 42a3817c
https://github.com/rails/rails/pull/11195This isn't a perfect tool: if a commit was made directly to master or a pull request was merged via git rebase, it will likely print a random pull request (since the script uses a simple git log --ancestry-path command to check for pull requests). Most of the time, however, it "does the right thing."
