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)

You can choose the side on which the diff appears (by default it's the right side)

'(version-control :variables
                  version-control-diff-side 'left)

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

Key Bindings

VC commands:

Key Binding	Description
SPC g .	version control transient-state
SPC g r	smerge mode transient-state
SPC g h o	browser at remote
SPC g v =	open a hunk under the point in the diff buffer
SPC g v D	compare the entire working tree with head
SPC g v e	show diff against current head using ediff
SPC g v g	visually annotate the current file
SPC g v d	open the VC Directory buffer
SPC g v +	update the working copy
SPC g v i	register (add) into a version control system
SPC g v u	revert working copy to their repository contents
SPC g v l	list the change log
SPC g v L	list the change log for the current VC controlled tree
SPC g v v	do the next logical VC operation (vc-next-action)
SPC g v I	ignore file (vc-ignore)
SPC g v r	resolve conflicts in file

VC Directory buffer commands

You can hit SPC pv from the current project to open the VC Directory buffer, or use SPC g v d for specifying a root directory. Then you may mark (m key) files you are interested in, to form a fileset. Most commands described above are applicable to filesets too. To some of them are given shortcuts:

Key	Description
=	compare selected files with head
c	open a commit message buffer
l	list changes
a	annotate selected files
i	add into a version control system
r	refresh directory view
E	ignore file under cursor

Navigation and interaction commands in the VC Directory buffer:

Key Bindings	Description
j or M-n	next file
k or M-p	previous file
gj or TAB	next directory
gk or S-TAB	previous directory
m	mark a file
u	unmark a file

Commit message editing buffer

In a commit message buffer press C-c C-c to commit the changes with the entered message. Pressing C-c C-k will discard the commit message and close this buffer.
