🛠️ Setup

Prompt configuration

See the following for examples for a reference on how you could add git-prompt-string to your prompt.

bash

PS1='\[\n\e[0;33m\w\e[0m$(git-prompt-string)\n\e[0;32mbash \e[0;36m\$\e[0m \]'

zsh

autoload -U colors && colors
setopt PROMPT_SUBST
PROMPT=$'\n%{$fg[yellow]%}%~%{$reset_color%}$(git-prompt-string)\n%{$fg[green]%}zsh %{$fg[cyan]%}%#%{$reset_color%} '

fish

set -U fish_prompt_pwd_dir_length 0
function fish_prompt
  set -l symbol ' $ '
  if fish_is_root_user
      set symbol ' # '
  end

  printf '\n%s%s%s%s\n%s%sfish%s%s%s' \
  (set_color yellow) (prompt_pwd) (set_color normal) (git-prompt-string) \
  (set_color green) (set_color blue) (set_color cyan) $symbol (set_color normal)
end

powershell

function prompt {
    $ESC = [char]27
    $w = $pwd.Path.Replace($env:USER_PROFILE, "~").Replace($env:HOME, "~")
    return "`n$ESC[0;33m$w$ESC[0m$(git-prompt-string)`n$ESC[0;32mPS $ESC[0;36m>$ESC[0m "
}

nushell

$env.PROMPT_INDICATOR = { ||
    $" (ansi cyan)>(ansi reset) "
}
$env.PROMPT_COMMAND = { ||
    $"\n(ansi yellow)($env.PWD | str replace $"($env.HOME)" '~')(git-prompt-string)\n(ansi green)nushell"
}
$env.PROMPT_COMMAND_RIGHT = ""

starship

Starship will hide custom commands that fail with a non-zero exit code. To prevent this, add || : or your shell's equvilent command to always return a zero exit code. It is recommended to always return successfully so that error messages are displayed.

"$schema" = 'https://starship.rs/config-schema.json'

format = """
$directory\
${custom.git-prompt-string}\
$line_break\
[starship](green) \
[\\$](cyan) \
"""

[custom.git-prompt-string]
command = "git-prompt-string || :"
when = true

[directory]
home_symbol='~'
format = '[$path]($style)'
truncation_length = 0
truncate_to_repo = false
style = "yellow"
use_logical_path = true

git-prompt-string configuration

Nerd Font

By default, the powerline icon  is used as a prefix in the prompt. It is recommended to use a Nerd Font to properly display the  (nf-pl-branch) icon. See https://www.nerdfonts.com/ to download a Nerd Font. If you do not want this symbol, replace the prompt prefix with " ". For example, add the following to you git-prompt-string configuration.

prompt_prefix = ' '

Configuration file

git-prompt-string will first check if the --config option was passed as an argument. If --config is set, the filepath defined in the value will be used as the configuration file.

If --config is not set, then git-prompt-string will check if the environment variable $GIT_PROMPT_STRING_CONFIG is set. If $GIT_PROMPT_STRING_CONFIG is set, the filepath defined in the value will be used as the configuration file.

If $GIT_PROMPT_STRING_CONFIG is not set, then git-prompt-string will check if the environment variable $XDG_CONFIG_HOME is set. If $XDG_CONFIG_HOME is set, the directory defined in then value will be used as the base directory for git-prompt-string configurations. See XDG Base Directory Specification for more information on XDG environment variables.

If $XDG_CONFIG_HOME is not set, then ~/.config and ~/AppData/Local will be used as the base directory for Unix and Windows, respectively.

The file defined at git-prompt-string/config.toml in the base directory will be used to configure git-prompt-string.

OS	Base directory	Configuration file
Unix	~/.config	~/.config/git-prompt-string/config.toml
Windows	~/AppData/Local	~/AppData/Local/git-prompt-string/config.toml

If the configuration filepath is set to the special value of NONE, then all user configurations will be ignored. For example, git-prompt-string --config=NONE or GIT_PROMPT_STRING_CONFIG=NONE git-prompt-string will use the default configuration values defined by git-prompt-string.

Configuration options

The following configuration options are available in either as a command-line argument or TOML key.

--ahead-format or ahead_format
      The format used to indicate the number of commits ahead of the

      ahead. One %v verb is required. (default "↑[%v]")

      from the remote branch. The first %v verb represents the number
      of commits ahead of the remote branch. The second %v verb
      represents the number of commits behind the remote branch. Two
      %v verbs are required. (default "↕ ↑[%v] ↓[%v]")

--no-upstream-remote-format or no_upstream_remote_format
      The format used to indicate when there is no remote upstream,
      but there is still a remote branch configured. The first %v
      represents the remote repository. The second %v represents the
      remote branch. Two %v are required. (default " → %v/%v")

--prompt-prefix or prompt_prefix
      A prefix that is added to the beginning of the prompt. The

      See https://www.nerdfonts.com/ to download a Nerd Font. If you
      do not want this symbol, replace the prompt prefix with " ".
      \ue0a0 is the unicode representation of . (default " \ue0a0 ")

--prompt-suffix or prompt_suffix
      A suffix that is added to the end of the prompt.

--json
      Output the results in JSON format. The keys of the JSON result are
      branchInfo, branchStatus, color, promptPrefix, and promptSuffix.
    
      Example:
      {
        "branchInfo": "main",
        "branchStatus": "",
        "color": "green",
        "promptPrefix": "  ",
        "promptSuffix": ""
      }

Specifying colors

A color value in the configuration must be either a single color or multiple colors separated by white space.

Valid formats for a color are:

• color
• fg:color
• bg:color
• #ffffff
• #fg:ffffff
• #bg:ffffff
• reset

The value reset will clear all text formatting and reset the color to the default value. Colors starting with bg or #bg are background colors. All other formats are considered foreground colors. i.e., red is equivalent to fg:reg.

Colors starting with # are considered a hex color code and must have 6 digits.

Valid colors are defined in the following table.

Color	Code
black	0
red	1
green	2
yellow	3
blue	4
magenta	5
cyan	6
white	7
bright-black	8
bright-red	9
bright-green	10
bright-yellow	11
bright-blue	12
bright-magenta	13
bright-cyan	14
bright-white	15

The following are examples of valid color configurations:

color_clean='#e5ee04'
color_no_upstream="reset fg:black bg:white"
color_dirty="bg:#b30559"
color_delta="fg:#fcb728"
color_untracked="fg:#ff0000 bg:#16f2aa"
color_merging="bg:#ccccff magenta"

Default configuration

prompt_prefix = '  '
prompt_suffix = ''
ahead_format = '↑[%v]'
behind_format = '↓[%v]'
diverged_format = '↕ ↑[%v] ↓[%v]'
no_upstream_remote_format = ' → %v/%v'
color_disabled = false
color_clean = 'green'
color_delta = 'yellow'
color_dirty = 'red'
color_untracked = 'magenta'
color_no_upstream = 'bright-black'
color_merging = 'blue'
