RubyCheckOnSave Sublime Text 2 Plugin

This simple plugin checks the syntax of ruby files when they're saved


If you made a syntax mistake in your ruby file it will raise a popup window on save. error_popup


With the Package Control plugin: The easiest way to install RubyCheckOnSave is through Package Control, which can be found at this site:

Once you install Package Control, restart ST2 and bring up the Command Palette (Command+Shift+P on OS X, Control+Shift+P on Linux/Windows). Select "Package Control: Install Package", wait while Package Control fetches the latest package list, then select RubyCheckOnSave when the list appears. The advantage of using this method is that Package Control will automatically keep RubyCheckOnSave up to date with the latest version.

Without Git: Download the latest source from GitHub and copy the RubyCheckOnSave folder to your Sublime Text 2 "Packages" directory.

With Git: Clone the repository in your Sublime Text 2 "Packages" directory:

git clone git://

The "Packages" directory is located at:

  • OS X:

      ~/Library/Application Support/Sublime Text 2/Packages/
  • Linux:

  • Windows:

      %APPDATA%/Sublime Text 2/Packages/


Do NOT edit the default RubyCheckOnSave settings. Your changes will be lost when RubyCheckOnSave is updated. ALWAYS edit the user RubyCheckOnSave settings by selecting Preferences->Package Settings->RubyCheckOnSave->Settings - User.

If you are using rvm or rbenv, you will probably have to specify the full path to the ruby you are using in the ruby_check_on_save_cmd setting.

Per project

RubyCheckOnSave supports per-project settings. This is useful if you work with several projects that requires different ruby interpreters. To edit your project settings, select the menu item Project->Edit Project. If there is no settings object at the top level, add one and then add the ruby_check_on_save_cmd setting, like this:

              "path": "/Users/edgar/sandboxes/repo"
          "ruby_check_on_save_cmd": "/Users/edgar/.rvm/rubies/ruby-1.9.3-p194/bin/ruby"
