Cannot execute RVM shell commands in ruby
As it happens, RVM actually exposes a Ruby API that's included by default. Add $HOME/.rvm/lib to your $LOAD_PATH; you can now use require 'rvm'.
As far as I can tell, the main documentation for this is in the source files themselves (a summary is in rvm.rb).
Now you can write Ruby scripts that manipulate RVM, like this:
require 'rvm'env = RVM.currentenv.gemset.create('newgemset')And so on.
