Signify (or just Sy) uses the sign column to indicate added, modified and removed lines in a file that is managed by a version control system (VCS).

• Supports git, mercurial, darcs, bazaar, subversion, cvs, rcs, fossil, accurev, perforce, tfs, yadm.
• Asynchronous execution of VCS tools for Vim 8.0.902+ and Neovim.
• Preserves signs from other plugins.
• Handles nested repositories controlled by different VCS.
• Provides mappings for navigating hunks ("blocks of changed lines").
• Provides an operator that acts on hunks.
• Preview changes in the current line in a popup window.
• Show all changes in diff mode.
• Alternative workflow: Disable the plugin by default and toggle it per buffer on demand.
• Optional line highlighting.
• Optional skipping of filetypes/filenames.
• Optional stats in the statusline.
• Works out of the box, but allows fine-grained configuration.
• Great documentation and handsome maintainers!

Similar plugin for git: vim-gitgutter

The master branch is async-only and thus requires at least Vim 8.0.902. Use the legacy tag for older Vim versions.

Using your favorite plugin manager, e.g. vim-plug:

if has('nvim') || has('patch-8.0.902')
  Plug 'mhinz/vim-signify'
else
  Plug 'mhinz/vim-signify', { 'tag': 'legacy' }
endif

" default updatetime 4000ms is not good for async update
set updatetime=100
