How do I open a gem for editing in RubyMine?

Question

Does anyone know how I can use RubyMine to open a gem for editing?

If this is not possible, then how do I set RubyMine as my default editor to open the gem?

Answer 1

On Mac, in your ~/.bash_profile:

export EDITOR=/Applications/RubyMine.app/Contents/MacOS/rubymine

then bundle open the-gem. Adjust to taste for other OSes.

You can also use RubyMine's "Tools -> Create Command line Launcher" to create a launcher script and set EDITOR to that.

Alternatively, if the gem you want to browse is part of a RubyMine project, you don't need to bother with bundle open: just open External Libraries at the very bottom of the Project tab, find the gem, and browse and edit just as you would your own code.

RubyMine will warn you before allowing you to edit a file in a gem, but will allow you to do so if you insist.

Answer 2

Very often you can just open gem in a project's tab.
