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.

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
• 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 :-)

Install

1. Clone this repository to your home directory.

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

2. Source the file gitprompt.sh from ~/.bashrc

3. cd to a git repository and test it!

Configuration

1. You can define GIT_PROMPT_START and GIT_PROMPT_END to tweak your prompt.

2. 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 git-prompt-colors.sh. 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.

3. The current git repo information is obtained by the script gitstatus.sh or gitstatus.py. Both scripts do the same thing, but the bash script is a tad more quick, and is used by default. If you prefer the python script (possibly because you have enhanced it), simply delete or change the name of gitstatus.sh.

4. 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
}

5. You can get help on the git prompt with the function git_prompt_help. Examples are available with git_prompt_examples.

Enjoy!
