* Install
** Layer
To use this contribution add it to your =~/.spacemacs=
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '(git))
#+END_SRC
** Magit status fullscreen
To display the =magit status= buffer in fullscreen set the variable
=git-magit-status-fullscreen= to =t= in your =dotspacemacs/init= function.
#+BEGIN_SRC emacs-lisp
(defun dotspacemacs/init ()
(setq-default git-magit-status-fullscreen t)
)
#+END_SRC
** Magit auto-complete
Magit auto-complete feature is enabled. For this feature to work best you
have to setup your Git repository directory in your =dotspacemacs/config=
function, this is the folder where you keep all your git-controlled projects
(the path should end up with a ~=/~= to respect Emacs conventions):
#+BEGIN_SRC emacs-lisp
(setq magit-repository-directories '("~/repos/"))
#+END_SRC
For more information, see [[https://magit.github.io/master/magit.html#Status][Magit-User-Manual#Status]]
** Magit SVN plugin
For convenience the magit SVN plugin can be activated directly in the Git
layer by setting the variable =git-enable-magit-svn-plugin= to =t=.
#+BEGIN_SRC emacs-lisp
(defun dotspacemacs/init ()
(setq-default git-enable-magit-svn-plugin t)
)
#+END_SRC
** Git
Of course if your OS does not ship with git (!) you'll have to install it
on your machine. You can download it from the [[http://git-scm.com/downloads][download page]].

** Magit
=Spacemacs= uses [[http://magit.github.io/][magit]] to manage Git repositories.
To open a =status buffer=, type in a buffer of a Git repository: ~SPC g s~
~hjkl~ navigation is enabled in all Magit buffers. The default Magit keys
on ~hjkl~ (if they exist) are remapped on ~HJKL~.
Here are the often used bindings inside a =status buffer=, please note that
the following key bindings are valid in Vim editing style, in Emacs editing
style you can refer directly to the magit manual:

| ~b c~ | create a branch |
| ~f f~ | fetch changes |
| ~F -r F~ | pull and rebase |
| ~h~ | go left |
| ~j~ | go down |

** Quick guide for recurring use cases in Magit
- Amend a commit:
- ~L l~ to open =log buffer=
- ~c a~ on the commit you want to amend
- ~C-c C-c~ to submit the changes
- Squash last commit:
- ~L l~ to open =log buffer=
- ~r e~ on the second to last commit, it opens the =rebase buffer=
- ~j~ to put point on last commit
- ~s~ to squash it
- ~C-c C-c~ to continue to the =commit message buffer=
- ~C-c C-c~ again when you have finished to edit the commit message
- Force push a squashed commit:
- in the =status buffer= you should see the new commit unpushed and the old
commit unpulled
- ~P -f P~ for force a push (*beware* usually it is not recommended to rewrite
the history of a public repository, but if you are *sure* that you are the
only one to work on a repository it is ok - i.e. in your fork).
- Add upstream remote (the parent repository you have forked):
- ~M~ to open the =remote popup=
- ~a~ to add a remote, type the name (i.e. =upstream=) and the URL
- Pull changes from upstream (the parent repository you have forked) and push:
- ~F -r C-u F~ and choose =upstream= or the name you gave to it
- ~P P~ to push the commit to =origin=
** Git time machine
[[https://github.com/pidu/git-timemachine][git-timemachine]] allows to quickly browse the commits of the current buffer.
| Key Binding | Description |
|-------------+------------------------------------------------|
| ~SPC g t~ | start git timemachine and initiate micro-state |
| ~c~ | show current commit |
| ~n~ | show next commit |
| ~N~ | show previous commit |
| ~p~ | show previous commit |
| ~q~ | leave micro-state and git timemachine |
| ~Y~ | copy current commit hash |
