How do I see Git diff markers in the sign column?

Explanation

vim-gitgutter shows git diff markers in the sign column next to line numbers. Added lines show +, modified lines show ~, and deleted lines show -.

How it works

• Install the plugin and signs appear automatically
• + in the gutter marks added lines
• ~ marks modified lines
• - marks deleted lines
• Updates asynchronously as you edit

Example

After modifying a git-tracked file, the gutter shows:

    1  unchanged line
 +  2  newly added line
 ~  3  modified line
    4  unchanged line
 -  5  (line was deleted after this)

Tips

• Install: Plug 'airblade/vim-gitgutter'
• ]c / [c jump between hunks
• :GitGutterPreviewHunk previews the change at cursor
• :GitGutterStageHunk stages the hunk under cursor
• :GitGutterUndoHunk reverts the hunk
• let g:gitgutter_enabled = 0 disables by default
