MacOS – How to use Sublime Text with the built-in Apple spellchecker

I've taken up olivier's suggestion to arrange my monitors to eliminate a common border:

I chose the bottom right because I keep my dock on the left hand side of my screen, and I use my upper right as a hot corner to sleep the display. I also moved the menu bar to my desktop monitor and the MacBook screen is completely dimmed.

There was another option I heard about: using a magnet to make your MacBook think that the lid was closed. This does work - I placed a snippet of a refrigerator magnet near the bottom left side of my keyboard and sure enough my MacBook thought I had closed the display. Unfortunately, Mac OS X also disables keyboard and trackpad input when it thinks the display is closed, so this option didn't work for me.

This worked for me.

Update ~/Library/Application\ Support/Sublime\ Text\ 2/Packages/Ruby/Ruby.sublime-build

{
  "env":{
      "PATH":"${HOME}/.rvm/bin:${PATH}"
  },
  "cmd": ["rvm-auto-ruby", "$file"],
  "file_regex": "^(...*?):([0-9]*):?([0-9]*)",
  "selector": "source.ruby"
}

The env part will add rvm-auto-ruby into the $PATH and the cmd will execute rvm-auto-ruby yourfile.rb when you press Cmd-B. You and add options in between rvm-auto-ruby if you want, like this `”cmd”: [“rvm-auto-ruby”, “-S”, “$file”].
