The :Bundle
command is meant to be put into your ~/.vimrc
, which is executed before all other initializations. Those won't run automatically when you later issue the :Bundle
command.
So, you'll need to add at least
:autocmd FileType python runtime! plugin/supertab.vim
to run the plugin initialization. (And then, those variables should show up, too!)
critique
I'd recommend against such dynamic plugin loads. Do you do them to speed up Vim startup? Do you really only want a general-purpose plugin like SuperTab loaded for Python files?!
