First, backup your existing .vim directory:
mv ~/.vim ~/.vim-backup
And backup your configuration files:
mv ~/.vimrc ~/.vimrc-backup
mv ~/.gvimrc ~/.gvimrc-backup
Now clone this repository:
git clone git://github.com/mwaisgold/groovy-vim-files.git ~/.vim
In your ~/.vimrc put this:
source ~/.vim/vimrc.vim
And in your ~/.gvimrc put this:
source ~/.vim/gvimrc.vim
You may want to explore the ~/.vim/config directory to see what's
included and ~/.vim/config/mappings.vim to see how to use the
available tools.
