A fast and easy-to-use tool for creating status bars.

**Lemonbuddy** aims to help users build beautiful and highly customizable status bars
for their desktop environment, without the need of having a black belt in shell scripting.
Heres a few screenshots showing you what it can look like:

## Introduction

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:

- 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).

## 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.

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

A compiler with c++14 support. For example [`clang`](http://clang.llvm.org/get_started.html).

- cmake
- boost
- xcb-util-wm
- libXft
- python2

Optional dependencies for module support:

- wireless_tools (required for `internal/network` support)
- alsa-lib (required for `internal/volume` support)
- libmpdclient (required for `internal/mpd` support)
- jsoncpp (required for `internal/i3` support)

~~~ sh
$ pacman -S cmake python2 boost xcb-util-wm libxft wireless_tools alsa-lib libmpdclient jsoncpp
$ apt-get install cmake cmake-data libboost-dev libfreetype6-dev libxcb1-dev libxcb-util0-dev libxcb-randr0-dev libxcb-ewmh-dev libxcb-icccm4-dev xcb-proto python-xcbgen i3-wm libiw-dev libasound2-dev libmpdclient-dev
~~~


### Building from source

Please [report any problems](https://github.com/jaagr/lemonbuddy/issues/new) you run into when building the project. It helps alot.

  ~~~ sh
  $ git clone --branch 2.0.0-beta --recursive https://github.com/jaagr/lemonbuddy
  $ mkdir lemonbuddy/build
  $ cd lemonbuddy/build
  $ cmake -DCMAKE_BUILD_TYPE=Release ..
  $ sudo make install
  ~~~


## Running

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:** In case 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.


## Launching the bar in your wm's bootstrap routine

Create an executable file containing the startup logic, for example `$HOME/.config/lemonbuddy/launch.sh`:
  ~~~ sh
  #!/usr/bin/env sh

  # Terminate already running bar instances
  killall -q lemonbuddy

  # Launch bar1 and bar2
  lemonbuddy bar1 &
  lemonbuddy bar2 &

  echo "Bars launched..."
  ~~~

Make it executable:
  ~~~ sh
  $ chmod +x $HOME/.config/lemonbuddy/launch.sh
  ~~~

If you are using **bspwm**, add the following line to `bspwmrc`:
  ~~~ sh
  $HOME/.config/lemonbuddy/launch.sh
  ~~~

If you are using **i3**, add the following line to your configuration:
  ~~~ sh
  exec_always --no-startup-id $HOME/.config/lemonbuddy/launch.sh
  ~~~


## 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).
