Description

This layers adds general configuration for Emacs VC. It should work with all VC backends such as Git, Mercurial, Bazaar, SVN, etc…

Features

• highlights uncommitted changes in the fringe or margin with diff-hl,

git-gutter, or git-gutter+

• adds vcs transient-state SPC g. to allow quick navigation and modification of

buffer hunks.

Install

Layer

To use this configuration layer, add it to your ~/.spacemacs. You will need to add version-control to the existing dotspacemacs-configuration-layers list in this file.

Configuration

You can choose the package to facilitate the diff transient-state and show margins by setting version-control-diff-tool

'(version-control :variables
                  version-control-diff-tool 'diff-hl)

To automatically enable diff margins in all buffers, set version-control-global-margin

'(version-control :variables
                  version-control-global-margin t)

Differences between margin programs

This layer contains generalized mappings for three diff margin packages: diff-hl, git-gutter, and git-gutter+.

There are some differences between packages that might have some people prefer one over the other:

Feature	diff-hl	git-gutter	git-gutter+
Show in fringe	X	X	X
Extended VCS support (e.g. hg, svn)	X	X
Stage hunks from buffer		X	X
Dired support	X
