dwl

installation

sudo pacman -S wlroots wayland-protocols xorg-xwayland kitty keyd wmenu slurp grim wl-clipboard
git clone 'https://github.com/vectorspacexyz/dwl.git'

The patches I applied were:

  1. bar-0.7.patch
  2. barcolors.patch
  3. moveresizekb.patch
  4. simple_scratchpad-v0.7.patch

All of the patches were very straightforward. However I had issues with barcolors patch. Look into drawstatus function to see the mods I've made (with Claude AI) to get it to work. However even with those mods I wasn't able to display nested fg-bg color formatting like: ^bg(FFFF00)^fg(000000)%s: %d%%^fg()^bg().

someblocks without somebar

Yeah so don't bother installing somebar.

cd ~/admin
git clone 'https://git.sr.ht/~raphi/someblocks/'
cd someblocks

You need to apply this patch: https://lists.sr.ht/~raphi/public-inbox/patches/56817

I copied it over to some.patch

patch -p1 <some.patch
make
sudo make install

The battery in the above script works alongside udev rules:

/etc/udev/rules.d/90-battery-monitor.rules
# Rule for when switching to battery
ACTION=="change", SUBSYSTEM=="power_supply", ATTRS{type}=="Mains", ATTRS{online}=="0", \
    RUN+="/bin/sh -c 'pgrep someblocks >/dev/null && pkill -SIGRTMIN+10 someblocks || true'"

# Rule for when switching to AC
ACTION=="change", SUBSYSTEM=="power_supply", ATTRS{type}=="Mains", ATTRS{online}=="1", \
    RUN+="/bin/sh -c 'pgrep someblocks >/dev/null && pkill -SIGRTMIN+10 someblocks || true'"

Reload udev:

sudo udevadm control --reload-rules
sudo udevadm trigger

On a related note you can get live battery info with:

acpi -i
