Lemonbuddy

A fast and easy-to-use tool for Lemonbar.

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.

Please note that the project hasn't been tested, other then by myself, so bugs and various bumps is to be expected. Please report any issues here on github.

Installation

Arch Linux

Install the AUR package lemonbuddy-git

Void Linux

A package will be written for XBPS so stay tuned.

Dependencies:

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

• lemonbar

  NOTE: The application has only been tested against the single-mon fork. If you have trouble running it with your current version, install the one included in contrib/lemonbar-sm-git. Plans are to make lemonbar an internal module.

• cmake
• boost
• libx11
• libxrandr
• wireless_tools (optional: used by the network module)
• alsa-lib (optional: used by the volume module)
• libmpdclient (optional: used by the mpd module)
• libsigc++ (optional: used by the i3 module)

Install dependencies using pacman:

$ sudo pacman -S cmake boost libx11 libxrandr wireless_tools alsa-lib libmpdclient libsigc++ i3-wm

Install dependencies using xbps-install:

$ sudo xbps-install -S cmake alsa-lib-devel boost-devel i3-devel libX11-devel libXrandr-devel libmpdclient-devel libsigc++-devel wireless_tools-devel

Install dependencies using apt-get:

NOTE: To get support for the mpd and i3 modules, the universe repository needs to be added to the list of sources in /etc/apt/sources.list.

Packages in the universe repository: libmpdclient-dev i3-wm

$ sudo apt-get install cmake libx11-dev libxrandr-dev libboost-dev libiw-dev libmpdclient-dev libsigc++-dev i3-wm

Building from source

NOTE: In Void Linux you will need to install git-perl to get support for submodules.

$ git clone --branch 0.1.2 --recursive https://github.com/jaagr/lemonbuddy.git
$ mkdir lemonbuddy/build
$ cd lemonbuddy/build
$ cmake ..
# Optionally list and edit build settings before compiling
# $ make edit_cache
$ 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=$(pgrep -l "(bspwm|i3)"); __prefix=$(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.sh example

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

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

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.sh 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. For example in $HOME/.config/bspwmrc:

# Terminate already running bar instances
pgrep -f '(lemonbuddy_wrapper.sh|^lemonb(uddy|ar))' | xargs kill -9 >/dev/null 2>&1

# Launch bar1 and bar2
lemonbuddy_wrapper.sh bar1 &
lemonbuddy_wrapper.sh bar2 &

echo "Bars launched..."

Configuration

The configuration syntax is very much WIP. If you have any feedback or suggestions, please create an issue ticket.

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, which has great unicode coverage.

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

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