fish_git_prompt - output git information for use in a prompt

Synopsis

function fish_prompt
     echo -n (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.
  • $__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

    exactly matching tag

  • $__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 (' ', |)
  • $__fish_git_prompt_color ('')
  • $__fish_git_prompt_color_prefix
  • $__fish_git_prompt_color_suffix
  • $__fish_git_prompt_color_bare
  • $__fish_git_prompt_color_merging

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

  • $__fish_git_prompt_char_cleanstate (✔)
  • $__fish_git_prompt_color_cleanstate

Variables used with showdirtystate:

  • $__fish_git_prompt_char_dirtystate (*, ✚)
  • $__fish_git_prompt_char_invalidstate (#, ✖)
  • $__fish_git_prompt_char_stagedstate (+, ●)
  • $__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 (%, …)
  • $__fish_git_prompt_color_untrackedfiles (same as color_flags)

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

  • $__fish_git_prompt_char_upstream_ahead (>, ↑)
  • $__fish_git_prompt_char_upstream_behind (<, ↓)
  • $__fish_git_prompt_char_upstream_diverged (<>)
  • $__fish_git_prompt_char_upstream_equal (=)
  • $__fish_git_prompt_char_upstream_prefix ('')
  • $__fish_git_prompt_color_upstream

Colors used with showcolorhints:

  • $__fish_git_prompt_color_branch (green)
  • $__fish_git_prompt_color_branch_detached (red)
  • $__fish_git_prompt_color_flags (--bold blue)

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
