A plugin which marks new, modified and deleted lines on the left side of the window.

Moreover, it can automatically stage hunks

• stage the hunk with hs or
• undo it with hu.

More informations are on the README. This is awesome.

My GitGutter conf in .vimrc:

" Icons for gitgutter
let g:gitgutr_sign_added                = '+'
let g:gitgutter_sign_modified           = '>'
let g:gitgutter_sign_removed            = '—'
let g:gitgutter_sign_removed_first_line = '^'
let g:gitgutter_sign_modified_removed   = '<'
set updatetime=200
highlight GitGutterAdd    guifg=#009900 ctermfg=2
highlight GitGutterChange guifg=#bbbb00 ctermfg=3
