MacVim now supports using your RVM ruby, making this plugin somewhat redundant. For the few remaining features you might want I'd recommend using Tim Pope's excellent rvm.vim.
Until MacVim supports RVM I've written this quick little plugin that provides a
Ruby
command.
Everything gets routed to the rvm
directory in your $HOME
folder. It
doesn't support alternate rvm
directories!
cd ~/.vim
git submodule add git://github.com/jcf/rvm_ruby.vim.git vim/bundle/rvm_ruby.vim
You can use the more traditional installation methods. Just dump the rvm_ruby.vim file in to plugin.
Pick a version of Ruby and open a Ruby file in MacVim:
rvm use 1.9.2-p0
mvim script.rb
Use the Ruby ex command:
:Ruby -v
And you'll get some nice output:
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]
