Lemonbuddy

A fast and easy-to-use tool for generating 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:

Please note that the project still is in early development, so please report any problems by creating an issue ticket.

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 using libmpdclient
ALSA volume controls
Workspace and desktop panel for bspwm and 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.

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 to get the latest version, or lemonbuddy for the latest stable release.

For Void Linux users, there's a package template available 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

A compiler with c++14 support. For example clang.

cmake
boost
libxcb
xcb-proto
freetype2

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, libsigc++ (required for internal/i3 support)

$ pacman -S cmake boost libxcb xcb-proto wireless_tools alsa-lib libmpdclient jsoncpp libsigc++
$ xbps-install cmake boost-devel libxcb-devel alsa-lib-devel i3-devel libmpdclient-devel jsoncpp-devel freetype-devel libsigc++-devel wireless_tools-devel
$ apt-get install cmake libxcb1-dev xcb-proto python-xcbgen libboost-dev libiw-dev libasound2-dev libmpdclient-dev libjsoncpp-dev libsigc++-2.0-dev libfreetype6-dev

Building from source

Please report any problems you run into when building the project. It helps alot.

$ git clone --branch 1.4.6 --recursive https://github.com/jaagr/lemonbuddy
$ mkdir lemonbuddy/build
$ cd lemonbuddy/build
$ cmake ..
$ 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:

# 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_wrapper example

NOTE: If you are running i3 or bspwm and you don't see the workspace icons it probably depends on the font. Install font-awesome and relaunch the bar. ...or replace the icons in the config.

It is recommended to always use lemonbuddy_wrapper when launching the bars.

lemonbuddy_wrapper is just a simple shell script that takes care of redirecting the in-/output streams between lemonbuddy and lemonbar.

If you handle the in-/output stream redirection's manually, the internal command handlers (e.g. mpd or volume controls) might stop working. It won't change the output of the bar but you will miss out on the internal API calls, which is one of the main advantages of using the application.

The lemonbuddy_wrapper will be deprecated once lemonbar is integrated into the project.

Launching the bar in your wm's bootstrap routine

When using the wrapper to start the bar in in your wm's autostart routine, make sure to include a kill directive before launching the bar. This is done to make sure that any previously spawned processes gets terminated before before we launch the new ones.

Create an executable file containing the startup logic, for example $HOME/.config/lemonbuddy/launch.sh:

#!/usr/bin/env sh

# Terminate already running bar instances
lemonbuddy_terminate noconfirm

# Launch bar1 and bar2
lemonbuddy_wrapper bar1 &
lemonbuddy_wrapper bar2 &

echo "Bars launched..."

Make it executable:

$ chmod +x $HOME/.config/lemonbuddy/launch.sh

If you are using bspwm, add the following line to bspwmrc:

$HOME/.config/lemonbuddy/launch.sh

If you are using i3, add the following line to your configuration:

exec_always $HOME/.config/lemonbuddy/launch.sh

Configuration

The configuration syntax is a work in progress. Please create an issue ticket and let me know how you think we can improve it.

The values used in the examples below are to be considered placeholder values, and the resulting output might not be award-winning.

Fonts

When working with unicode symbols, remember that fonts render the symbols differently. Changing font can drastically improve the quality of your bar. One must-have font is Unifont, which has great unicode coverage.

Also try different icon fonts, such as Font Awesome and Material Icons.
