wcp - Wayland Control Panel

Script-driven control panel/system menu for wayland based window managers.

Wayland Control Panel was made for SwayOS (https://swayos.github.io)

Watch the introduction/user guide video on youtube

Features

• content and style fully configurable via html and css
• functionality fully controllable via shell scripts
• super lightweight ( no gtk & qt )

Description

Wayland control panel is an application for popup control menu, system menu or any kind of menu for UNIX-like operating systems. You can trigger it's appereance with a shortcut or with a button in the status bar. It can be structured via html, styled via css. Button, label and slider values are coming from scripts and it can invoke scripts in case of interaction, it's totally configurable. By default it looks for config files under ~/.config/wcp/ and falls back to /usr/local/share/wcp.

Installation

Compiling from source

Install the needed dependencies and libraries:

git meson ninja-build pkg-config
libpng,libfreetype,
libgl,libglew,libegl,libwegl,wayland-client,wayland-protocols,xkbcommon,gles2
fonts-terminus

On debian based systems ( over version 12 ):

sudo apg-get install git meson ninja-build pkg-config libpng-dev libfreetype-dev libgl-dev libegl-dev libglew-dev libwayland-dev libxkbcommon-dev wayland-protocols libgles2-mesa-dev

On arch based systems :

sudo pacman -Qs git meson pkg-config ninja glew wayland-protocols libpng freetype2 libgl libegl wayland wayland-protocols libxkbcommon 

or use the AUR

Then run these commands:

git clone git@github.com:milgra/wcp.git
cd wcp
meson build --buildtype=release
ninja -C build
sudo ninja -C build install

From packages

Usage

Launch wcp in a terminal, enter 0 to hide, 1 to show, 2 to toggle, 3 to quit wcp and press return.

wcp

Usage with sway wm

Launch wcp in the config connected to a named pipe, but remove the named pipe first to avoid mkfifo errors.

exec rm -f /tmp/wcp && mkfifo /tmp/wcp && tail -f /tmp/wcp | wcp

Set up your sway config or menu bar config to toggle wcp

For example, to toggle with META+P

bindsym $mod+p exec "echo 2 > /tmp/wcp"

Configuration

Copy the html, img and script folders from /usr/local/share/wcp under ~/.config/wcp/
Edit ~/.config/wcp/html/main.html to add or remove new items from the control panel Edit ~/.config/wcp/html/main.css to modify, add and remove styles.
Add new images needed by new styles under ~/.config/wcp/img/
Add new script under ~/.config/wcp/script

Creating new scripts

The idea is the following :
if a script doesn't receive any arguments then it should return a string value ( integers between 0 and 100 in case of sliders, strings in case of labels ),
if it receives an argument ( integer between 0 and 100 in case of sliders, 1 in case of button ) then the script should do something.

Technical Info

WCP was written in Headerless C. It is about using the INCLUDE_LEVEL preprocessor macro available in GCC/CLANG to guard the implementation part of a source file so you can place it together with the header definition in a single file and you include this file freely in other source files. Read more about this in (https://github.com/milgra/headerlessc);

WCP uses Kinetic UI as UI/Widget rendering engine. It is a modern, minimal ui renderer with html/css based stylimg written in headerless C. It offers MacOS like smooth kinetic animations and font-level animatioms, gpu or cpu based alpha blending, wayland connector with window and layer support and deterministic session record and replay for fully automated application testing.

WCP uses the mt_core library for retain counted memory management, retain counted and recursively observable vector and map containers and helper functions.

WCP uses meson and ninja for lightning fast compilation.

Contribution/Development

Feel free to push fixes/improvements.

Please follow these guidelines :

• use clang format before commiting/after file save
• use zen_core functions and containers and memory handling
• make sure that the app is leak free. if you run the dev build it automagically checks for leaks on exit on two levels (zc_memory and clang address sanitizer ) and prints leaks

Creating a debug build :

CC=clang meson build --buildtype=debug -Db_sanitize=address -Db_lundef=false
ninja -C build
