Rulebar is a horizontal progress indicator plugin for vim displayed in the statusline.
For documentation, go to the reference manual, which is best viewed in vim after installation:
:h rulerbar
In short, rulerbar will replace the standard ruler output with something that looks like this:
37,16 ┈┈┈███████┈ 78% ~
This displays the current window position within a buffer.
The recommended way to install rulerbar is to use the vim pathogen plugin, and to clone rulerbar into your bundle directory:
cd .vim/bundle
git clone git://github.com/zenzike/vim-rulerbar.vim
