Running passenger for development is great, but if you’re hacking code within a plugin then it’s cumbersome to constantly touch tmp/restart.txt and refresh your browser, even if you use tou[UP] to pick the command from your history.

Using fish and some applescript, you can do it all from your terminal by hitting ⌥R.

function reload_webkit
  osascript -e 'tell application "WebKit" to do JavaScript \
    "window.location.reload()" in front document'
end

function restart_rails_app
  touch tmp/restart.txt
  reload_webkit
end

bind \er 'restart_rails_app >/dev/null'
