Open a project file on GitHub.

Repo

#!/bin/bash
#
# Open the specified file on GitHub. It will use the master branch by default:
#
#   repo -f app/controllers/application_controller.rb
#
# Specify a different branch:
#
#   repo -b another-branch -f app/controllers/application_controller.rb

if [ -d .git ]; then
  echo "Opening on Github..."

  # Set the default branch to current branch instead of 'master'
  # BRANCH=$(git rev-parse --abbrev-ref HEAD)
  BRANCH='master'

  while getopts ":b:f:" option
  do
    case "$option" in
      b) BRANCH=$OPTARG;;
      f) FILEPATH=$OPTARG;;
    esac
  done

  BASE=$(git config --get remote.origin.url | sed s/\\.git// | sed 's/:/\//' | sed 's/.*github.com/https:\/\/github.com/')
  URL="$BASE/blob/$BRANCH/$FILEPATH"

  if which xdg-open > /dev/null
  then
    xdg-open $URL
  elif which gnome-open > /dev/null
  then
    gnome-open $URL
  elif which open > /dev/null
  then
    open $URL
  fi
  echo "Opened $URL"
else
  echo "Not a git repo"
fi

Thanks for the handy work. I've made a minor tweak to the script to be able to open any file relative to the parent working tree avoiding the need to specify the complete path on the command line.
