sublime text helper in .irbrc

I wanted to be able to open helper methods from irb using sublime text on Mac OS X.

In order to do this you first need to create a command line helper to for sublime text.

ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/local/bin/sublime

This creates a symlink that you can use from the command line to open sublime text 2. Now we can use it in our .irbrc method.  Here is what i added to our .irbrc file:

def sublime(method_name)
  file, line = method(method_name).source_location
  `sublime '#{file}:#{line}'`
end

Now from IRB you can do this sort of thing:

>> helper.sublime(:link_to)

And it opens sublime text at the line number of the link_to method.

This is pretty nice. But, of course, what i’d really like is a way of opening the source for any method. Not sure how to go about that.

Also, if i could only get this to work with emacs. I can get emacs to open, but i haven’t spent the time to figure out how to get it to open to a given line number. Here is what i have:

def emacs(method_name)
  file, line = method(method_name).source_location
  `emacs '#{file}'`
end

The only clue to opening on a given line i found here, on stack overflow:

opening a file in emacs with at a line number.
