Using better_errors with Sublime Text 2

I have been using better_errors to provide a better error page on a few Rails 3 projects. It provides more information and gives me a live REPL at the source of the error.

This week I realized that the file name is actually a link to open the source file in my editor.

The default link uses the TextMate handler (txmt://open?url=...), but since I’m using Sublime Text 2 I wanted to change the url and setup a handler on my system for ST.

First, the system handler. I searched around and found this: https://github.com/asuth/subl-handler. After downloading and following the instructions, it works perfectly. Now ST responds to any subl:// urls.

Next, changing the URL on the error page. After some digging I was able to find out how to change the url. It’s pretty simple; just add this to config/environments/development.rb:

BetterErrors.editor = :sublime

And it works! Clicking on the filename will open the file to the exactly line in ST.
