Informative git prompt for bash

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).

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
• (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
• (◉v0.0.1|✔): not on any branch; parent commit is referenced by tag with name v0.0.01 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
• 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
  If you are currently not on any branch, instead of branch name you would see short HEAD commit hash preceded with a colon (:)
  If you are currently not on any branch, but commit you are on is referenced by tag, tag name preceded with fisheye (◉) would be show

Install

1. Create the directory ~/.bash if it does not exist (this location is customizable).
2. Move the file gitstatus.py into ~/.bash/.
3. Source the file gitprompt.sh from your ~/.bashrc config file, and, configure your prompt in ~/.bash/gitprompt.sh. For this you have to set the variables PROMPT_START and PROMPT_END.
4. You may also redefine the function setGitPrompt to adapt it to your needs (to change the order in which the information is displayed).
5. Go in a git repository and test it!

Enjoy!
