I got sick of going through multiple steps to visit the current directory's github URL when I'm looking at a terminal, but I don't necessarily want to install `gh` or `hub` just for this feature.

github

#!/usr/bin/env ruby

begin
  repo = `git remote -v`.split("\n").find { |line|
    line.include?("github.com")
  }.split("\t")[1].match(/git@github.com:(.*).git/)[1]

  system "open https://github.com/#{repo}"
rescue
  warn "No github remote found"
  exit 1
end
