问题
I am running rails3 in Ubuntu and using gedit for coding. I am using RVM. To look at the gem source code I tried: bundle open jquery-rails
That doesn't work since I hadn't setup an editor. After setting gedit as the editor it still doesn't work because gedit can't be passed directories. I guess it only works with files. Too bad :(.
nathan.f77's answer to this question ( Lookup Gem or Plugin code packaged in a Rails3 application ) seems promising, but I wasn't able to follow his instructions. They lacked sufficient detail for me.
What is a very easy way to browse the source files for gems that I am using in my rails3 app?
回答1:
bundle show jquery-rails should tell you where the gem source lives on your filesystem. Then open the file that you want.

CubaLibre's response got me half-way there. The other piece of the puzzle I was able to get from Ask Ubuntu.
Here are the steps to browse gem code in gedit using Ubuntu.
a. From the command line run:
gnome-open $(bundle show [gem-name])
b. This will open up the gem directory in nautilus. From there just double click on file you'd like to see and it will open up in gedit.

Assuming you have a default editor set in your terminal, on MacOS you can do something like this example (atom is my editor, but should work with sublime or textmate, vim, etc.):
atom $(bundle show name_of_gem)
