Git
===
Enhances the [Git][1] distributed version control system by providing aliases, functions and by exposing repository status information to prompts.
Git **1.7.2** is the [minimum required version][7].
Settings
--------
### Log
The format of the [git-log][8] output is configurable via the following style,
where context is *brief*, *oneline*, and *medium*, which will be passed to the
`--prety=format:` switch.
zstyle ':prezto:module:git:log:context' format ''
### Status
Retrieving the status of a repository with submodules can take a long time.
Submodules may be ignored when they are *dirty*, *untracked*, *all*, or *none*.
zstyle ':prezto:module:git:status:ignore' submodules 'all'
This setting affects all aliases and functions that call `git-status`.

You can temporarily bypass an alias by prefixing it with a backward slash:
`\gpt`.

Theming
-------
To display information about the current repository in a prompt, define the
following styles in the `prompt_name_setup` function, where the syntax for
setting a style is as follows.
zstyle ':prezto:module:git:info:context:subcontext' format 'string'
| Name | Format Code | Description
| --------- | :---------: | ---------------------------------------------------
| action | %s | Special action name
| added | %a | Added files count
| ahead | %A | Commits ahead of remote count
| behind | %B | Commits behind of remote count
| branch | %b | Branch name
| commit | %c | Commit hash
| clean | %C | Clean state
| deleted | %d | Deleted files count
| dirty | %D | Dirty files count
| modified | %m | Modified files count
| position | %p | Commits from the nearest tag count
| remote | %R | Remote name
| renamed | %r | Renamed files count
| stashed | %S | Stashed states count
| unmerged | %U | Unmerged files count
| untracked | %u | Untracked files count
[**Main Contexts**]
| Name | Format | Description
| -------------------- | :---------: | -----------------------------------------
| apply | value | Applying patches
| bisect | value | Binary searching for changes
| cherry-pick | value | Cherry picking
| cherry-pick-sequence | value | Cherry picking sequence
| merge | value | Merging
| rebase | value | Rebasing
| rebase-interactive | value | Rebasing interactively
| rebase-merge | value | Rebasing merge
[**Special Action Contexts**]
First, format the repository state attributes. For example, to format the branch
and remote names, define the following styles.
zstyle ':prezto:module:git:info:branch' format 'branch:%b'
zstyle ':prezto:module:git:info:remote' format 'remote:%R'
Second, format how the above attributes are displayed in prompts.
zstyle ':prezto:module:git:info:keys' format \
'prompt' ' git(%b)' \
'rprompt' '[%R]'
Last, add `$git_info[prompt]` to `$PROMPT` and `$git_info[prompt]` to
`$RPROMPT` respectively and call `git-info` in the `prompt_name_preexec` hook
function.
