Did you know it’s possible to run (aka build) your Ruby code straight from inside of Sublime Text 2?

That’s easy, just make sure your code is saved as a .rb file and hit Command+B.  But wait, there’s more…

Did you also know it’s possible to run your Ruby code straight from inside of Sublime Text 2… using RVM’s default Ruby?

There might be a better way but here’s one a quick and dirty for an OSX environment.  If you are using Linux, it’s hopefully the same but with the file paths modified:

Step 1:
Cut a hole in a box.

Step 2:
Open `~/Library/Application Support/Sublime Text 2/Packages/Ruby/Ruby.sublime-build`
And replace it’s contents with the following (be sure to substitute your user name):

 

Step 3:

• Launch Sublime Text 2
• Open a ruby file
• Hit Command+B
• The Sublime Text console should pop up with your output. If you want it to go away, hit escape.

Want to prove it’s working?

Here’s a quick script that computes factorial and then prints out the result AND the ruby version using ruby’s constant “RUBY_VERSION”:

 

Drop that into your own factorial.rb, open it in Sublime Text, and hit Command+B.  It should look something like this:

As you can see above, that’s 1.9.3… and as you can see below… that’s what my RVM is set to use as it’s default ruby.
