Informative git prompt for bash and fish

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:

(master↑3|✚1): on branch master, ahead of remote by 3 commits, 1 file changed but not staged
(status|●2): on branch status, 2 files staged
(master|✚7…): on branch master, 7 files changed, some files untracked
(master|✖2✚3): on branch master, 2 conflicts, 3 files changed
(master|⚑2): on branch master, 2 stash entries
(experimental↓2↑3|✔): on branch experimental; your branch has diverged by 3 commits, remote by 2 commits; the repository is otherwise clean
(:70c2952|✔): not on any branch; parent commit has hash 70c2952; the repository is otherwise clean

Prompt Structure

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

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

The symbols are as follows:

Local Status Symbols
- ✔: repository clean
- ●n: there are n staged files
- ✖n: there are n unmerged files
- ✚n: there are n changed but unstaged files
- …n: there are n untracked files
- ⚑n: there are n stash entries
Branch Tracking Symbols
- ↑n: ahead of remote by n commits
- ↓n: behind remote by n commits
- ↓m↑n: branches diverged, other by m commits, yours by n commits
- L: local branch, not remotely tracked
Branch Symbol:
When the branch name starts with a colon :, it means it's actually a hash, not a branch (although it should be pretty clear, unless you name your branches like hashes :-)

Installation

via Homebrew on Mac OS X

Run brew update
Run brew install bash-git-prompt for the last stable release or brew install --HEAD bash-git-prompt for the latest version directly from the repository
Now you can source the file in your ~/.bash_profile as follows:

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

via Git clone

Clone this repository to your home directory.

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

Source the file gitprompt.sh from ~/.bashrc

Configuration

   # some other config in .bashrc

   # gitprompt configuration

   # Set config variables first
   GIT_PROMPT_ONLY_IN_REPO=1

   # GIT_PROMPT_FETCH_REMOTE_STATUS=0   # uncomment to avoid fetching remote status

   # 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 .git-prompt-colors.sh
   # GIT_PROMPT_THEME=Solarized # use theme optimized for solarized color scheme
   source ~/.bash-git-prompt/gitprompt.sh

cd to a git repository and test it!

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.

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

You can define GIT_PROMPT_START and GIT_PROMPT_END to tweak your prompt.
The default colors are defined within prompt-colors.sh, which is sourced by gitprompt.sh. The colors used for various git status are defined in themes/Default.bgptheme. Both of these files may be overridden by copying them to $HOME with a . prefix. They can also be placed in $HOME/lib without the leading .. The defaults are the original files in the ~/.bash-git-prompt directory.
You can use GIT_PROMPT_START_USER, GIT_PROMPT_START_ROOT, GIT_PROMPT_END_USER and GIT_PROMPT_END_ROOT in your .git-prompt-colors.sh to tweak your prompt. You can also override the start and end of the prompt by setting GIT_PROMPT_START and GIT_PROMPT_END before you source the gitprompt.sh.
The current git repo information is obtained by the script gitstatus.sh.
You can define prompt_callback function to tweak your prompt dynamically.

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

If you want to show the git prompt only if you are in a git repository you can set GIT_PROMPT_ONLY_IN_REPO=1 before sourcing the gitprompt script
There is an indicator at the start of the prompt, which shows the result of the last executed command by if you put the placeholder _LAST_COMMAND_INDICATOR_ in any of the prompt templates. It is now by default activated in the default theme:

  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

It is now possible to disable the fetching of the remote repository either globally by setting GIT_PROMPT_FETCH_REMOTE_STATUS=0 in your .bashrc or on a per repository basis by creating a file named .bash-git-rc with the content FETCH_REMOTE_STATUS=0 in the root of your git repository.
You can also ignore a repository completely by creating a file named .bash-git-rc with the content GIT_PROMPT_IGNORE=1 in the root of your git repository.
You can get help on the git prompt with the function git_prompt_help. Examples are available with git_prompt_examples. A list of all available named colors is available with git_prompt_color_samples
If you make any changes to any file that is sourced by gitprompt.sh, you should run this command, so that the next prompt update will find all the files and source them anew.

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:

Clone this repository and tag the release with a version number

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

Run the following command to create a tarball:

    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

Log into an RHEL or clones host and run:

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

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