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 is still in early development, so please report any anomalies by creating an issue ticket here on GitHub. I welcome pull requests with fixes or improvements.

Here's a screenshot showing you an example of what it could look like:

Installation

Arch Linux

Install the AUR package lemonbuddy-git to get the latest version, or lemonbuddy for the latest stable release.

Void Linux

A package will be written for XBPS so stay tuned.

Dependencies:

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

• lemonbar
• 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)

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.

Install dependencies using pacman:

$ sudo pacman -S cmake boost libx11 libxrandr wireless_tools alsa-lib libmpdclient libsigc++
$ yaourt ttf-font-awesome

Install dependencies using xbps-install:

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

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 fonts-font-awesome

$ sudo apt-get install cmake libxrandr-dev libboost-dev libiw-dev libasound2-dev libmpdclient-dev libsigc++-2.0-dev
$ sudo apt-get install fonts-font-awesome

Building from source

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

$ git clone --branch 0.2.0 --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=$(pgrep -l -x "(bspwm|i3)"); __prefix=$(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.sh 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.sh when launching the bars.

lemonbuddy_wrapper.sh 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.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. An upcoming change will replace all occurences of colon's with dashes in the parameter names. 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.
