## Introduction
2016-10-12 03:35:33 +00:00
The main purpose of **Lemonbuddy** is to help users create awesome status bars.
It has built-in functionality to generate content for the most commonly used widgets, such as:
2016-06-29 02:44:55 +00:00
- Playback controls and status display for [MPD](https://www.musicpd.org/) using [libmpdclient](https://www.musicpd.org/libs/libmpdclient/)
- [ALSA](http://www.alsa-project.org/main/index.php/Main_Page) volume controls
- Workspace and desktop panel for [bspwm](https://github.com/baskerville/bspwm) and [i3](https://github.com/i3/i3)
- CPU and memory load indicator
- Battery display
- Network connection details
- Backlight level
- Date and time label
- Time-based shell script execution
- Command output tailing
- User-defined menu tree
- And more...
Each bar contains a set of modules, which in turn defines a set of formatting rules and options.

### Configuration
*Details on how to setup and configure the bar and each module have been moved to [the wiki](https://github.com/jaagr/lemonbuddy/wiki/Configuration).*
Before customizing the bar, make sure everything works as expected by trying
out one of the example configurations installed with the application.
The following code will get you started:
~~~ sh
# Create the config root directory
$ mkdir -p ${XDG_CONFIG_HOME:-$HOME/.config}/lemonbuddy
$ cd ${XDG_CONFIG_HOME:-$HOME/.config}/lemonbuddy
# Copy sample config for the running wm (uses a wm agnostic config as fallback)
$ __wm=$(pgrep -l -x "(bspwm|i3)"); __prefix=$(which lemonbuddy)
$ cp "${__prefix%%/bin*}/share/examples/lemonbuddy/config${__wm:+.${__wm##* }}" config
# Launch the bar
# (where "example" is the name of the bar as defined by [bar/NAME] in the config)
$ lemonbuddy example
~~~
**NOTE:** If the bar output looks odd, it's probably because you're
missing he fonts defined in the config. Update the config or install the
missing fonts.
