Git branch in Tmux

tmux-git shows information about the git repo of the current directory in tmux status bar, like current branch, dirtiness, stash, etc.

Overview

There are many solutions to integrate the current Git branch on your Linux terminal prompt (like this one and this one, from where I borrowed most parts of this script), but I don't like to bloat my prompt.

So I was thinking where can I put that information, and then I remembered the fabulous Tmux. tmux is a powerful and really cool client-server terminal multiplexer, but it also provides a nice status bar.

This script scans the current bash directory for a git repo. If it's found, then puts information about it in the status bar, like:

• Project name (actually, is the git repo directory name)
• Active branch
• 'Dirty' status (i.e., there are pending modifications to be committed)
• Stashed changes

Installation

Clone this project in your home directory, renaming the folder with a preceding dot for hiding it:

git clone git://github.com/drmad/tmux-git.git ~/.tmux-git

Then, execute this line in a shell to add the script in the Bash initialization file (usually .bashrc, replace if needed):

echo "if [[ \$TMUX ]]; then source ~/.tmux-git/tmux-git.sh; fi" >> ~/.bashrc

Run tmux, cd to a Git repo, and enjoy :)

Note for OSX users: You'll need to install coreutils:

brew install coreutils

Configuration

The configuration is stored in the file ~/.tmux-git.conf, created at the first run of the script with default values. Just edit it, and reload tmux.

Variables and functions

• TMUX_STATUS_LOCATION: Position of the status on Tmux bar: left or right
• TMUX_OUTREPO_STATUS: Tmux status for when you're out of a repo. Set by default to your pre-existing status line.
• TMUX_STATUS_DEFINITION(): This function sets the TMUX_STATUS variable, which is shown in the tmux bar. You can use any variable used across the script for creating this variable.
