# vc-got
This is an **experimental** Emacs VC back-end for the [Game of
Tree](http://gameoftrees.org/) version control system.
Use it at your own risk.
------
To start using it, you need to add `Got` to `vc-handled-backends` and
make sure that `vc-got` is within your `load-path`. You shouldn't
require the library.
```emacs-lisp
(add-to-list 'vc-handled-backends 'Got)
```
It's highly recommended to add `".got"` to the list of
`vc-directory-exclusion-list`.
```emacs-lisp
(add-to-list 'vc-directory-exclusion-list ".got")
```
With `use-package` something like this should be enough:
```emacs-lisp
(use-package vc-got
:load-path "/path/to/vc-got/"
:defer t
:init
(add-to-list 'vc-handled-backends 'Got)
(add-to-list 'vc-directory-exclusion-list ".got"))
```
### vc-got-stage-mode
`vc-got-stage-mode` is a minor mode to stage individual changes
(currently you can't commit the staged changes).
The Emacs VC system usually operates at a *fileset* level: i.e. it can
commit/rollback/etc sets of file. Yet, sometimes you may want to
commit only individual changes (eventually from multiple files), and
VC doesn't support this. This is the motivation behind
`vc-got-stage-mode`.
The following keys are enabled by `vc-got-stage-mode`:
| key | description |
|--------------------|------------------------------------------------|
| <kbd>C-c g A</kbd> | Applies (i.e. stage in got) the marked changes |
| <kbd>C-c g b</kbd> | Go to beginning of change |
| <kbd>C-c g e</kbd> | Go to end of change |
| <kbd>C-c g n</kbd> | Go to next change |
| <kbd>C-c g p</kbd> | Go to previous change |
| <kbd>C-c g t</kbd> | Toggle mark |
A change is a set of sequential line added/removed by the diff, it is
a smaller unit than a *hunk*.
The staged changes are indicated by an arrow in the left fringe.
