How do I force Sublime Text to indent two spaces per tab?

Question

Is there a way to force Sublime Text 2 to always indent two spaces per tab when working with Ruby files?

I know that indentation can be set under the view -> indentation menu option, but it does not stick. Every time I open a new file and hit tab, it reverts back to four spaces.

If you want it for all files, go to Preferences -> Settings - Default/User. But as several comments below indicate, Syntax Specific settings can limit it to just the languages you choose.

To limit this configuration to Ruby files, first open up a Ruby file in the editor, and then go to Preferences -> Settings - Syntax Specific. This should open a settings window named Ruby.sublime-settings

Save these settings:

{
  "tab_size": 2,
  "translate_tabs_to_spaces": true,
  "detect_indentation": false
}

Repeat for any other syntax types by opening a file of that type and going back to the preferences to open the correct preferences file for that syntax.

I have edited this to include the "detect_indentation" line per the requests in comments; I previously used the Default/User to set my tab size, and have not needed the tab detection, but whether that is due to the global config or due to the fact that I have rarely opened files with tabs, I do not know.

Restarting should not be necessary, although in some instances it can be.
