Battery

Battery is a little bash script that uses Spark to display the battery status on your tmux sessions or the terminal.

Features

• Changes color to reflect battery status (Green, Yellow, Red)
• Displays battery percentage
• Graph bar changes its values between 0 and 100% (thanks to spark)
• If you don't like the default colors, you can specify the good, medium and warning battery status colors using flags (read usage).

Requirements

Right now, battery requires Spark to graph your battery status, and only runs on Mac OS X.

If you don't want to use Spark, you can use the -a flag, for ascii output:

Install

Homebrew

Just do (case sensitive)

brew tap Goles/battery
brew install battery

One Liner

(Cut & Paste on terminal to install on /usr/bin, btw, try to run from ~/ or other writable dir)

brew install spark; curl -O https://raw.github.com/Goles/Battery/master/battery ; \
sudo mv battery /usr/bin; sudo chmod 755 /usr/bin/battery

Step by Step

• Install spark (with Homebrew on Mac OS X)

  brew install spark

• Copy battery somewhere in your path & fix permissions

  sudo cp battery /usr/bin

  sudo chmod 755 /usr/bin/battery

Usage

Terminal

• Run Battery (From the terminal)

  battery

You should see something like this:

tmux

• Be sure to make tmux display utf-8 characters by running it with the -u flag

  tmux -u

• Add the following line to your ~/.tmux.conf file

  set -g status-right "#(/usr/bin/battery -t)"

• reload the tmux config by running tmux source-file ~/.tmux.conf.

You should now see something like this at the bottom right corner:

Flags

You can specifiy the colors for good battery level, middle battery level, and warning battery level with the flags -g -m -w.

Note: You should use color names for when in tmux mode and ascii colors in terminal mode.
