FISH_GIT_PROMPT(1)

NAME
fish_git_prompt - output git information for use in a prompt

SYNOPSIS
fish_git_prompt

function fish_prompt
     printf '%s' $PWD (fish_git_prompt) ' $ '
end

DESCRIPTION

The fish_git_prompt function displays information about the current git repository, if any.

Git must be installed.

There are numerous customization options, which can be controlled with git options or fish variables. git options, where available, take precedence over the fish variable with the same function. git options can be set on a per-repository or global basis. git options can be set with the git config command, while fish variables can be set as usual with the set command.

•   $__fish_git_prompt_show_informative_status or the git option bash.showInformativeStatus can be set to enable the "informative" display, which will show a large amount of information - the number of untracked files, dirty files, unpushed/unpulled commits, and more. In large repositories, this can take a lot of time, so it you may wish to disable it in these repositories with git config --local bash.showInformativeStatus false. It also changes the characters the prompt uses to less plain ones (✚ instead of * for the dirty state for example) , and if you are only interested in that, set $__fish_git_prompt_use_informative_chars instead.

•   $__fish_git_prompt_showdirtystate or the git option bash.showDirtyState can be set to show if the repository is "dirty", i.e. has uncommitted changes.

•   $__fish_git_prompt_showuntrackedfiles or the git option bash.showUntrackedFiles can be set to show if the repository has untracked files (that aren't ignored).

•   $__fish_git_prompt_showupstream can be set to a list of values to determine how changes between HEAD and upstream are shown:

auto
    summarize the difference between HEAD and its upstream

verbose
    show number of commits ahead/behind (+/-) upstream

name
    if verbose, then also show the upstream abbrev name

informative
    similar to verbose, but shows nothing when equal - this is the default if informative status is enabled.

git always compare HEAD to @{upstream}

svn always compare HEAD to your SVN upstream

none
    disables (useful with informative status)

•   $__fish_git_prompt_showstashstate can be set to display the state of the stash.

•   $__fish_git_prompt_shorten_branch_len can be set to the number of characters that the branch name will be shortened to.

•   $__fish_git_prompt_describe_style can be set to one of the following styles to describe the current HEAD:

contains
    relative to newer annotated tag, such as (v1.6.3.2~35)

branch
    relative to newer tag or branch, such as (master~4)

describe
    relative to older annotated tag, such as (v1.6.3.1-13-gdd42c2f)

default
    an exactly matching tag ((develop))

    If none of these apply, the commit SHA shortened to 8 characters is used.

•   $__fish_git_prompt_showcolorhints can be set to enable coloring for the branch name and status symbols.

    A number of variables set characters and color used as indicators. Many of these have a different default if used with informative status enabled, or $__fish_git_prompt_use_informative_chars set. The usual default is given first, then the informative default (if it is different). If no default for the colors is given, they default to $__fish_git_prompt_color.

•   $__fish_git_prompt_char_stateseparator (' ', |) - the character to be used between the state characters

•   $__fish_git_prompt_color (no default)

•   $__fish_git_prompt_color_prefix - the color of the ( prefix

•   $__fish_git_prompt_color_suffix - the color of the ) suffix

•   $__fish_git_prompt_color_bare - the color to use for a bare repository - one without a working tree

•   $__fish_git_prompt_color_merging - the color when a merge/rebase/revert/bisect or cherry-pick is in progress

    Some variables are only used in some modes, like when informative status is enabled:

•   $__fish_git_prompt_char_cleanstate (✔) - the character to be used when nothing else applies

•   $__fish_git_prompt_color_cleanstate

    Variables used with showdirtystate:

•   $__fish_git_prompt_char_dirtystate (*, ✚) - the number of "dirty" changes, i.e. unstaged files with changes

•   $__fish_git_prompt_char_invalidstate (#, ✖) - the number of "unmerged" changes, e.g. additional changes to already added files

•   $__fish_git_prompt_char_stagedstate (+, ●) - the number of staged files without additional changes

•   $__fish_git_prompt_color_dirtystate (red with showcolorhints, same as color_flags otherwise)

•   $__fish_git_prompt_color_invalidstate

•   $__fish_git_prompt_color_stagedstate (green with showcolorhints, color_flags otherwise)

    Variables used with showstashstate:

•   $__fish_git_prompt_char_stashstate ($, ⚑)

•   $__fish_git_prompt_color_stashstate (same as color_flags)

    Variables used with showuntrackedfiles:

•   $__fish_git_prompt_char_untrackedfiles (%, …) - the symbol for untracked files

•   $__fish_git_prompt_color_untrackedfiles (same as color_flags)

    Variables used with showupstream (also implied by informative status):

•   $__fish_git_prompt_char_upstream_ahead (>, ↑) - the character for the commits this repository is ahead of upstream

•   $__fish_git_prompt_char_upstream_behind (<, ↓) - the character for the commits this repository is behind upstream

•   $__fish_git_prompt_char_upstream_diverged (<>) - the symbol if this repository is both ahead and behind upstream

•   $__fish_git_prompt_char_upstream_equal (=) - the symbol if this repo is equal to upstream

•   $__fish_git_prompt_char_upstream_prefix ('')

•   $__fish_git_prompt_color_upstream

    Colors used with showcolorhints:

•   $__fish_git_prompt_color_branch (green) - the color of the branch

•   $__fish_git_prompt_color_branch_detached (red) the color of the branch if it's detached (e.g. a commit is checked out)

•   $__fish_git_prompt_color_flags (--bold blue) - the default color for dirty/staged/stashed/untracked state

    Note that all colors can also have a corresponding _done color. For example, the contents of $__fish_git_prompt_color_upstream_done is printed right _after_ the upstream.

    See also fish_vcs_prompt, which will call all supported version control prompt functions, including git, Mercurial and Subversion.

EXAMPLE

A simple prompt that displays git info:

function fish_prompt
    # ...
    set -g __fish_git_prompt_showupstream auto
    printf '%s %s$' $PWD (fish_git_prompt)
end
