My patched version of dwm based on the git.suckless.org/dwm repo
Run the following command
makepkg -Acs --skipchecksums -f
This should build the package. Then install it using pacman. For example:
sudo pacman -U dwm-6.1-2-x86_64.pkg.tar.xz
By default, Shift+Alt+q will shut down dwm, allowing you to restart after you've installed your changes.
The freebsd branch contains the files needed to add to the port (in the /usr/ports/x11-wm/dwm/files directory).
Once those files are added, you can make and install the system using the config.h file with the following command:
sudo make DWM_CONF=/usr/ports/x11-wm/dwm/files/config.h install
