Dotvim is a project mainly written in ..., it's free.
My Vim config to make it easier to get going on a new machine
Build MacVim with cscope if you want to use the Flog gem. Here is how to get it with homebrew:
brew install macvim --enable-cscope
Don't forget to install ack if you want to use the grep replacement. I went for the homebrew install:
brew install ack
The Flog gem is needed for showing the complexity score in the sidebar
gem install flog
cd ~
git clone http://github.com/cimm/dotvim.git ~/.vim
ln -s ~/.vim/vimrc ~/.vimrc
cd ~/.vim
git submodule update --init
