Optimal Way to Browse Gem Source Code

I find that browsing source code of open source libraries being used in projects is invaluable. Unfortunately, I find this difficult when developing with ruby on rails. I am accustomed to working inside IDE's that allow me to jump to the definitions of symbols, regardless of whether they are part 开发者_运维问答of an external library.

I use Aptana Studio 3 on Mac OS X to develop, but would be willing to change IDEs for this feature.

I have explored https://github.com/fnando/gem-open as an option, but have yet to find a good editor to integrate this with. Can anyone recommend one? Anyone else have a good method for browsing the sources of gems?

Aptana Studio 3 has a command line launcher: studio3.

Add the following to your ~/.bash_profile:

export PATH="/Applications/Aptana Studio 3:$PATH"
export GEM_EDITOR="studio3"

Reload your existing shell environment: . ~/.bash_profile and then you can use gem-open with your preferred editor: gem open rails
