Informative git prompt for bash and fish

Gitter

This prompt is a port of the "Informative git prompt for zsh" which you can find here

A bash prompt that displays information about the current git repository. In particular the branch name, difference with remote branch, number of files staged, changed, etc.

(an original idea from this blog post).

gitstatus.sh and git-prompt-help.sh added by AKS.

ATTENTION! Breaking changes!

If you use this prompt already, please update your .git-prompt-colors.sh, if you have one. It now contains a function named define_git_prompt_colors() or override_git_prompt_colors()!

Please see the Custom.bgptemplate in the themes subdirectory of the installation directory!

You can now also use the function override_git_prompt_colors(). It should define the variable GIT_PROMPT_THEME_NAME and call the function reload_git_prompt_colors <ThemeName> like follows:

override_git_prompt_colors() {
  GIT_PROMPT_THEME_NAME="Custom" # needed for reload optimization, should be unique

  # Place your overrides here
  ...
}

# load the theme
reload_git_prompt_colors "Custom"

The advantage of this approach is, that you only need to specify the parts, that are different to the Default theme.

The variable GIT_PROMPT_SHOW_LAST_COMMAND_INDICATOR was replaced with a more general placeholder named _LAST_COMMAND_INDICATOR_, which is replaced by the state of the last executed command. It is now activated by default.

Examples

The prompt may look like the following:

Prompt Structure

By default, the general appearance of the prompt is::

(<branch> <upstream branch> <branch tracking>|<local status>)

The symbols are as follows:

Installation

via Homebrew on Mac OS X

if [ -f "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh" ]; then
  __GIT_PROMPT_DIR=$(brew --prefix)/opt/bash-git-prompt/share
  source "$(brew --prefix)/opt/bash-git-prompt/share/gitprompt.sh"
fi

via Git clone

cd ~
git clone https://github.com/magicmonty/bash-git-prompt.git .bash-git-prompt --depth=1

Add to the ~/.bashrc:

  GIT_PROMPT_ONLY_IN_REPO=1
  source ~/.bash-git-prompt/gitprompt.sh

install for the fish shell

sudo install -m 666 gitprompt.fish /usr/share/fish/tools/web_config/sample_prompts/
fish_config

to install the bash-git-prompt as a choice under the prompt tab of the web config. Selecting this will copy it to ~/.config/fish/functions/fish_prompt.fish

mkdir -p ~/.config/fish/functions/
cp gitprompt.fish ~/.config/fish/functions/fish_prompt.fish

to overwrite the current prompt with the bash-git-prompt directly

All configs for .bashrc


   # Set config variables first
   GIT_PROMPT_ONLY_IN_REPO=1

   # GIT_PROMPT_FETCH_REMOTE_STATUS=0   # uncomment to avoid fetching remote status
   # GIT_PROMPT_IGNORE_SUBMODULES=1 # uncomment to avoid searching for changed files in submodules

   # GIT_PROMPT_SHOW_UPSTREAM=1 # uncomment to show upstream tracking branch
   # GIT_PROMPT_SHOW_UNTRACKED_FILES=normal # can be no, normal or all; determines counting of untracked files

   # GIT_PROMPT_SHOW_CHANGED_FILES_COUNT=0 # uncomment to avoid printing the number of changed files

   # GIT_PROMPT_STATUS_COMMAND=gitstatus_pre-1.7.10.sh # uncomment to support Git older than 1.7.10

   # GIT_PROMPT_START=...    # uncomment for custom prompt start sequence
   # GIT_PROMPT_END=...      # uncomment for custom prompt end sequence

   # as last entry source the gitprompt script
   # GIT_PROMPT_THEME=Custom # use custom theme specified in file GIT_PROMPT_THEME_FILE (default ~/.git-prompt-colors.sh)
   # GIT_PROMPT_THEME_FILE=~/.git-prompt-colors.sh
   # GIT_PROMPT_THEME=Solarized # use theme optimized for solarized color scheme
   source ~/.bash-git-prompt/gitprompt.sh

You can set the GIT_PROMPT_SHOW_UNTRACKED_FILES variable to no or normal to speed things up if you have lots of untracked files in your repository. This can be the case for build systems that put their build artifacts in the subdirectory structure of the git repository. Setting it to all will count all untracked files, including files listed in .gitignore.

Themes

The most settings are now stored in theme files. To select a theme, set the variable GIT_PROMPT_THEME to the name of the theme located in <INSTALLDIR>/themes without the extension .bgptheme like this:

GIT_PROMPT_THEME=Solarized

If you set GIT_PROMPT_THEME to Custom, then the .git-prompt-colors.sh in the home directory will be used. This file can now be generated with the command git_prompt_make_custom_theme [<Name of base theme>]. If the name of the base theme is ommitted or the theme file is not found, then the Default theme is used. If you have already a custom .git-prompt-colors.sh in your home directory, a error message will be shown.

You can display a list of available themes with git_prompt_list_themes (the current theme is highlighted)

If you omit the GIT_PROMPT_THEME variable, the Default theme is used or, if you have a custom .git-prompt-colors.sh in your home directory, then the Custom theme is used.

Ubuntu Themes

Ubuntu requires a bit more spacing for some characters so it has its own themes.

These can be listed with git_prompt_list_themes:

git_prompt_list_themes | grep Ubuntu
Theme structure

Please see the Custom.bgptemplate in the themes subdirectory of the installation directory!

A theme consists of a function override_git_prompt_colors() which defines at least the variable GIT_PROMPT_THEME_NAME with a unique theme identifier and a call to the function reload_git_prompt_colors <ThemeName> like follows:

override_git_prompt_colors() {
  GIT_PROMPT_THEME_NAME="Custom" # needed for reload optimization, should be unique

  # Place your overrides here
  ...
}

# load the theme
reload_git_prompt_colors "Custom"

The advantage of this approach is, that you only need to specify the parts, that are different to the Default theme.

If you use a custom theme in .git-prompt-colors.sh, please set GIT_PROMPT_THEME_NAME="Custom".

Further customizations

function prompt_callback {
    if [ `jobs | wc -l` -ne 0 ]; then
        echo -n " jobs:\j"
    fi
}

  GIT_PROMPT_START_USER="_LAST_COMMAND_INDICATOR_ ${Yellow}${PathShort}${ResetColor}"
  GIT_PROMPT_START_ROOT="_LAST_COMMAND_INDICATOR_ ${GIT_PROMPT_START_USER}"

If you want to display the exit code too, you can use the placeholder _LAST_COMMAND_STATE_ in GIT_PROMPT_COMMAND_OK or GIT_PROMPT_COMMAND_FAIL in your .git-prompt-colors.sh:

GIT_PROMPT_COMMAND_OK="${Green}✔ " # displays as ✔
GIT_PROMPT_COMMAND_FAIL="${Red}✘-_LAST_COMMAND_STATE_ " # displays as ✘-1 for exit code 1

git_prompt_reset

git_prompt_toggle

Enjoy!

Alternative RPM Install

This project ships an RPM spec to simplify installation on RHEL and clones. If you wish to install from RPM, you may first build the RPM from scratch by following this procedure:

    git tag -a -m "Tag release 1.1" 1.1

    VER=$(git describe)
    # replace dash with underscore to work around
    # rpmbuild does not allow dash in version string
    VER=${VER//\-/_}
    git archive                                \
        --format tar                           \
        --prefix=bash-git-prompt-${VER}/       \
        HEAD                                   \
        --  *.sh                               \
            *.fish                             \
            README.md                          \
            themes                             \
      > bash-git-prompt-${VER}.tar
    mkdir -p /tmp/bash-git-prompt-${VER}
    sed "s/Version:.*/Version:        ${VER}/"          \
        bash-git-prompt.spec                            \
      > /tmp/bash-git-prompt-${VER}/bash-git-prompt.spec
    OLDDIR=$(pwd)
    cd /tmp
    tar -uf ${OLDDIR}/bash-git-prompt-${VER}.tar      \
            bash-git-prompt-${VER}/bash-git-prompt.spec
    cd ${OLDDIR}
    gzip bash-git-prompt-${VER}.tar
    mv bash-git-prompt-${VER}.tar.gz bash-git-prompt-${VER}.tgz

rpmbuild -ta bash-git-prompt-xxx.tar.gz

Then you may publish or install the rpm from "~/rpmbuild/RPMS/noarch".
