A fast and easy-to-use tool for generating status bars.
**Lemonbuddy** aims to help users build beautiful and highly customizable status bars
without messing with named pipes, MacGyver-like scripting or non-blocking
loops lobotomizing your CPU.
for their desktop environment, without the need of having a black belt in shell scripting.

## Introduction
The main purpose of **Lemonbuddy** is serve as content generator for status bars.
It has built-in functionality to generate output for the most commonly used widgets, such as:
- 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.
Read more about [how the configuration works](#configuration).
The project was developed specifically for Lemonbar, and the initial plan was to
integrate a trimmed down version of it into Lemonbuddy. This would remove the need of having
to pass data back and forth between the two processes.
After spending time trying to create an interface to the Lemonbar source code, I
decided to not use it at all. Lemonbar is a great application but it would be
more efficient to write a custom X rendering implementation instead of trying
to patch up Lemonbar. Not only does it fix the
*"Lemonbuddy doesn't work with my extra-custom-lemonbar-fork"* issue, it also
makes it alot easier to implement new features... The performance boost is of
course also welcome to join the party, so that's nice.
The new implementation will use the same `%{...}` syntax Lemonbar uses, which means that
existing configurations will still work, so keep ricing.
## Getting started
If you are using **Arch Linux**, you can install the AUR package [lemonbuddy-git](https://aur.archlinux.org/packages/lemonbuddy-git/) to get the latest version, or
[lemonbuddy](https://aur.archlinux.org/packages/lemonbuddy/) for the latest stable release.
#### Void Linux
Install the XBPS package [lemonbuddy](https://raw.githubusercontent.com/jaagr/void-packages/lemonbuddy/srcpkgs/lemonbuddy/template) for the latest stable release.
For **Void Linux** users, there's a [package template available](https://raw.githubusercontent.com/jaagr/void-packages/lemonbuddy/srcpkgs/lemonbuddy/template)
that you can use with `xbps-src` to build the application. There's a pending pull request to get the package merged into the
official repositories, but packages not used by the maintainers are pretty much ignored so don't hold your breath.
If you create a package for any other distribution, please consider contributing the template so that we can make the application
available for more people.
### Dependencies

The configuration syntax is very much **WIP**. If you have any feedback or suggestions on how to improve it,
please [create an issue ticket](https://github.com/jaagr/lemonbuddy/issues), or a pull request.
When working with unicode symbols, remember that fonts render them differently. Changing font
can change the quality of your generated output drastically. One must-have font
is [Unifont](http://unifoundry.com/unifont.html), which has great unicode coverage.
Also try different icon fonts, such as [Font Awesome](http://fontawesome.io/icons/) and [Material Icons](https://design.google.com/icons/).
