Create GitHub pull request from the command line

git-pr

#!/usr/bin/env ruby
remote_url = `git config --get remote.origin.url`.strip

matches = remote_url.match(/github\.com:(.+)\/(.+)\.git/)
if matches
    branch_name = `git rev-parse --abbrev-ref HEAD`.strip
    exec "open https://github.com/#{matches[1]}/#{matches[2]}/compare/#{branch_name}?expand=1"
end

# Save this file as ~/bin/git-pr and then `chmod +x ~/bin/git-pr`.
# Then, you can create a pull request for your current branch by typing `git pr`. Woohoo!

This looks safer (in case the matches have unexpected, evil characters):

 exec "open", "https://github.com/#{matches[1]}/#{matches[2]}/compare/#{branch_name}?expand=1"

From http://www.ruby-doc.org/core-2.1.5/Kernel.html#method-i-exec :

In the second form (exec("command1", "arg1", ...)), the first is taken as a command name and the rest are passed as parameters to command with no shell expansion.
