Smultron is an open-source text-editor for OS X. It’s a very lean editor, but it’s fast and it was written in Cocoa. Out of the box it has syntax highlighting for Stata and LaTeX, but not R. Basic instructions for adding a rudimentary R syntax coloring file are available here. However, I have adapted the R syntax module for TextWrangler for Smultron.

There are two files: the keyword list and the syntax definitions file, which tells Smultron which languages are available.

In order to install, you have to add these files to the application bundle. To do so:

  1. Right-click on Smultron and select Show in finder
  2. Right-click on the Smultron application (in the ~/Applications folder) and select Show package contents
  3. Copy the above files to the directory ./Contents/Resources within the application bundle
  4. Restart Smultron
