I’ve been listening to RubyRogues which introduced me to Avdi Grimm from the Ruby community. I’ve also been subscribed to his RubyTapas screencast series which is a 2x a week Ruby show.

He uses a neat tool called rcodetools to execute Ruby code from within an Emacs buffer. Unfortunately, it wasn’t working when I tried to use the VIM counterpart, with segfault codes showing up. Here’s the fix: ( I’m using RVM to manage my Ruby Versions ) *Install Tim Pope’s excellent rvm extension for VIM cd ~/.vim/bundle git clone git://github.com/tpope/vim-rvm.git

*Install rcodetools using RVM gem install rcodetools

*Remove keybindings in other programs (ie Dashboard & Expose) for F10, F11, F12 or rebind the keys per README.vim

Now enter a VIM file and type F12 on any lines that you want the output from followed by F11 to evaluate the whole file. If you want to only re-evaluate the current line use F10 instead of F11.

It’s a great tool for terminal screencasting! Thanks Avdi for letting me know that this tool is available.
