|
## Install
|
|
|
|
### Layer
|
|
|
|
To use this contribution add it to your `~/.spacemacs`
|
|
|
|
```elisp
|
|
(setq-default dotspacemacs-configuration-layers '(git))
|
|
```
|
|
|
|
### Github support
|
|
|
|
To enable the Github support set the variable `git-enable-github-support`
|
|
to `t` in your `dotspacemacs/init` function.
|
|
|
|
```elisp
|
|
(defun dotspacemacs/init ()
|
|
(setq-default git-enable-github-support t)
|
|
)
|
|
```
|
|
|
|
### 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.
|
|
|
|
```elisp
|
|
(defun dotspacemacs/init ()
|
|
(setq-default git-magit-status-fullscreen t)
|
|
)
|
|
```
|
|
|
|
### 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 (the path should end up with a `/` to respect Emacs conventions):
|
|
|
|
```elisp
|
|
(setq magit-repo-dirs '("~/git/"))
|
|
```
|
|
|
|
### 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`.
|
|
|
|
```elisp
|
|
(defun dotspacemacs/init ()
|
|
(setq-default git-enable-magit-svn-plugin t)
|
|
)
|
|
```
|
|
|
|
### Git gutter
|
|
|
|
In graphical environment `Spacemacs` will display [git-gutter][] icons in
|
|
the fringe by default.
|
|
|
|
It is possible to disable the usage of the fringe by setting the variable
|
|
`git-gutter-use-fringe` to `nil` in the `dotspacemacs/init` function:
|
|
|
|
```elisp
|
|
(defun dotspacemacs/init ()
|
|
(setq-default git-gutter-use-fringe nil)
|
|
)
|
|
```
|
|
|
|
### Git
|
|
|
|
Of course if your OS does not ship with git (!) you'll have to install it
|
|
on your machine, [download page][].
|
|
|
|
## Working with Git
|
|
|
|
Git commands (start with `g`):
|
|
|
|
Key Binding | Description
|
|
---------------------------|------------------------------------------------------------
|
|
<kbd>SPC g b</kbd> | open a `magit` blame
|
|
<kbd>SPC g C</kbd> | commit changes
|
|
<kbd>SPC g h c</kbd> | clear highlights
|
|
<kbd>SPC g h h</kbd> | highlight regions by age of commits
|
|

<kbd>SPC g m</kbd> | display the last commit message of the current line
|
|
<kbd>SPC g t</kbd> | launch the git time machine
|
|
|
|
- Highlight by age of commit or last update time is provided by
|
|
[smeargle][].
|
|
- Git time machine is provided by [git-timemachine][].
|
|
- Git last commit message per line is provided by
|
|
[git-messenger][]
|
|
|
|
### Magit
|
|
|
|
`Spacemacs` uses [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`:
|
|
|
|
Key Binding | Description
|
|
------------------|------------------------------------------------------------
|
|
<kbd>/</kbd> | evil-search
|
|
<kbd>$</kbd> | open `command output buffer`
|
|
<kbd>c c</kbd> | open a `commit message buffer`
|
|
<kbd>b b</kbd> | checkout a branch
|
|
<kbd>b c</kbd> | create a branch
|
|
<kbd>b v</kbd> | open the `branch manager buffer`
|
|
<kbd>f f</kbd> | fetch changes
|
|
<kbd>F -r F</kbd> | pull and rebase
|
|
<kbd>h</kbd> | go left

|
|
<kbd>C-k</kbd | goto previous magit section
|
|
<kbd>l</kbd> | go right
|
|
<kbd>L l</kbd> | open `log buffer`
|
|
<kbd>n</kbd> | next search occurrence
|
|
<kbd>C-n</kbd | goto next magit section
|
|
<kbd>N</kbd> | previous search occurrence _or_ SVN sub-menu
|
|
<kbd>P P</kbd> | push
|
|
<kbd>C-p</kbd | goto previous magit section
|
|
<kbd>q</kbd> | quit
|
|
<kbd>s</kbd> | on a file or hunk in a diff: stage the file or hunk
|
|
<kbd>+</kbd> | on a hunk: increase hunk size
|
|
<kbd>-</kbd> | on a hunk: decrease hunk size
|
|
<kbd>S</kbd> | stage all
|
|
<kbd>TAB</kbd> | on a file: expand/collapse diff
|
|
<kbd>u</kbd> | on a staged file: unstage
|
|
<kbd>U</kbd> | unstage all staged files
|
|
<kbd>v</kbd> | `visual state`
|
|
<kbd>V</kbd> | `visual-line state`
|
|
<kbd>C-v</kbd> | revert item at point
|
|
<kbd>z z</kbd> | stash changes
|
|
|
|
In a commit message buffer press `C-c C-c` to commit the changes with the
|
|
entered message. `C-c C-k` will discard the commit message.
|
|
|
|
**Note:** Sometimes you will be asked about reverting the commit buffer,
|
|
you can answer `y` with no issue.
|
|
|
|
### 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`
|
|
- `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):
|
|
- `b v` to open the `branch manager buffer`
|
|
- `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
|
|
|
|
[git-timemachine] allows to quickly browse the commits of the current buffer.
|
|
|
|
Key Binding | Description
|
|
--------------------|------------------------------------------------------------
|
|
<kbd>SPC g t</kbd> | start git timemachine and initiate micro-state
|
|
<kbd>c</kbd> | show current commit
|
|
<kbd>n</kbd> | show next commit
|
|
<kbd>N</kbd> | show previous commit
|
|
<kbd>p</kbd> | show previous commit
|
|
<kbd>q</kbd> | leave micro-state and git timemachine
|
|
|
|
### Git gutter
|
|
|
|
With [git-gutter][] it is possible to navigate between hunks, stage them and
|
|
revert them.
|
|
|
|
Git gutter hunks commands start with `gh`:
|
|
|
|
Key Binding | Description
|
|
----------------------|------------------------------------------------------------
|
|
<kbd>SPC g h n</kbd> | next hunk in buffer
|
|
<kbd>SPC g h N</kbd> | previous hunk in buffer
|
|
<kbd>SPC g h r</kbd> | revert current hunk
|
|
<kbd>SPC g h s</kbd> | stage current hunk
|
|
|
|
`Spacemacs` has custom fringe bitmaps for [git-gutter-fringe][git-gutter]:
|
|
|
|
Symbol | Description
|
|
:-------------------------------:|-----------------
|
|
 | new line
|
|
 | at least one line has been deleted
|
|
 | modified line
|
