Our Recommendation

On OSX, we suggest using Sublime. Sublime has an indefinite free trial period, but it will prompt you to purchase a license (you can ignore this for now).


Sublime Text is available from Sublime's web page. It has a (non-free) license, but you can use the free trial period for as long as you like.


  • Go to the main page and click on the blue button that says "Download for OS X".
  • Save the file to your desktop or downloads folder (or another convenient location).
  • Double click on the file (Sublime Text 2.0.1.dmg) to extract it.
  • In the newly opened window, drag the file Sublime Text into the Applications folder (a shortcut to your computer's Applications folder).
  • To run Sublime:
    • Search for Sublime Text 2 in the Spotlight.
    • OR Start Finder, select Applications from the left menu, then find and double-click on Sublime Text 2.
  • If a text-editor window doesn't pop up, let a staff member know.


  • Start the Sublime Text editor.
  • With Sublime as the active window, click on Sublime Text 2 in the top menu, scroll the mouse over Preferences, then click Settings - Default. A new tab will open with text and options in it.
  • Scroll down until you see the line "translate_tabs_to_spaces": false,
  • On that line, change false to true so that it reads "translate_tabs_to_spaces": true,
  • Save the settings by pressing Command+s or clicking on File, then Save.
  • Now every time you press the tab key, it should insert four spaces instead of a tab.


If you prefer a different editor for text, check with an instructor before moving on to make sure it will work for the rest of the workshop.
