cwc

cwc is:

an extensible Wayland compositor with dynamic window management based on wlroots. Highly influenced by Awesome window manager, cwc use Lua for its configuration and C plugin for extension.

Installation

Install the cwc^AUR package.

Starting

Select cwc from the menu in a display manager of choice.

LXQT

LXQt#Wayland Session

Configuration

System-wide cwc configuration files are in /usr/share/cwc/defconfig/ while user configuration files are in ~/.config/cwc:

rc.lua — the main cwc resource configuration file.
keybindings.lua — cwc keybindings
oneshot.lua — where to launch startup apps

Creating the configuration file

First, run the following to create the directory needed in the next step:

$ mkdir -p ~/.config/cwc/

Whenever compiled, cwc will attempt to use whatever custom settings are contained in ~/.config/cwc/rc.lua. This file is not created by default, so we must copy the template file first:

$ cp /usr/share/cwc/defconfig/* ~/.config/cwc/

Autostart

autostarting is done by

~/.config/cwc/oneshot.lua

for example:

cwc.spawn_with_shell("swaybg --output '*' --color '#222222'")

Wallpaper

you can use a wallpaper setter such as feh or swww

Tips and tricks

Screenshot

See Keyboard input to ensure the PrtSc button is assigned correctly. Then install a screen capturing program such as flameshot

Add to the globalkeys array:

kbd.bind({ MODKEY }, "Print", function()
   cwc.spawn_with_shell("flameshot full")

Removing window gaps

it is possible to remove the small gaps between windows; in the screen/tag config table there is a properties section, add to it

 cwc.screen.set_useless_gaps(3)

].

Media Controls

It is possible to control both volume and media playback via a combination of amixer(1) (available via the alsa-utils package) and playerctl. The following can be added to the relevant key binding section of your rc.lua configuration file:

  ------------ Audio Media Keys
   kbd.bind({}, "XF86AudioLowerVolume", function()
       local cmd = string.format("pactl set-sink-volume @DEFAULT_SINK@ %s%%", "-3")
       cwc.spawn_with_shell(cmd)
   end, { exclusive = true, repeated = true })
   kbd.bind({}, "XF86AudioRaiseVolume", function()
       local cmd = string.format("pactl set-sink-volume @DEFAULT_SINK@ %s%%", "+3")
       cwc.spawn_with_shell(cmd)
   end, { exclusive = true, repeated = true })
   kbd.bind({}, "XF86AudioMute", function()
       cwc.spawn_with_shell("pactl set-sink-mute @DEFAULT_SINK@ toggle")
   end, { exclusive = true })
   kbd.bind({}, "XF86AudioMicMute", function()
       cwc.spawn_with_shell("pactl set-source-mute @DEFAULT_SOURCE@ toggle")
   end, { exclusive = true })

   -------------- Media Player Keys
   kbd.bind({}, "XF86AudioPlay", function()
       cwc.spawn_with_shell("playerctl play-pause")
   end, { exclusive = true })
   kbd.bind({}, "XF86AudioNext", function()
       cwc.spawn_with_shell("playerctl next")
   end, { exclusive = true })
   kbd.bind({}, "XF86AudioPrev", function()
       cwc.spawn_with_shell("playerctl previous")
   end, { exclusive = true })
   kbd.bind({}, "XF86AudioStop", function()
       cwc.spawn_with_shell("playerctl stop")
   end, { exclusive = true })
   kbd.bind({}, "XF86AudioRewind", function()
       cwc.spawn_with_shell("playerctl position 5-")
   end, { exclusive = true })
   kbd.bind({}, "XF86AudioForward", function()
       cwc.spawn_with_shell("playerctl position 5+")
   end, { exclusive = true })
