Gem Editor

→ ‘gemedit’

What

Gemedit lets you quickly open up the source for a gem in your favorite editor.

Looking through other people’s code is a great way to learn. I often use it when a gem’s RDoc isn’t as helpful as I’d like or just want to see how someone put a library together. Gemedit just makes it easier to get to the code.

Installing

$ sudo gem install gemedit

If you would like some basic command completion for installed gems add the following to your ~/.bashrc or ~/.profile:

complete -C "/usr/bin/gemedit --complete" gemedit

Demonstration of usage

If you want to see how gemedit works just install it and run this:

$ gemedit gemedit

Gemedit tries to use your favorite editor from your $VISUAL or $EDITOR environment variable. It will fall back to everyone’s favorite editor: vi. You can specify the editor with the -e/--editor switch. Run this to view the source for rake in TextMate:

$ gemedit -e mate rake

And of course, help is available:

$ gemedit -h

$ gemedit --help

Documentation:

There isn’t much more to document than what is on this page, but feel free to browse the RDoc. Or checkout the Rubyforge project page.

Source Repository:

The source is currently on github. You can browse through it at http://github.com/lmarlow/gemedit or pull it down and play with it yourself with

$ git clone git://github.com/lmarlow/gemedit.git
