vim-auto-origami

Automatically set vim's 'foldcolumn' when folds present

Check it out on vim.org too.

Installation

I recommend using Pathogen for managing plugins.

Then it's just a quick

cd ~/.vim/bundle
git clone https://github.com/benknoble/vim-auto-origami.git

Quickstart

Drop the following in your vimrc, and open a file with some folds

augroup autofoldcolumn
  au!

  " Or whatever autocmd-events you want
  au CursorHold,BufWinEnter,WinEnter * AutoOrigamiFoldColumn
augroup END

Usage

Check out the docs (:help auto-origami).
