+
+Largely based on [[https://sr.ht/~raphi/][raphi]]'s [[https://sr.ht/~raphi/somebar/][somebar]], this patch provides an ipc for wayland clients to get and set dwl state. The ipc is intended for status bars, but can also be scripted with tools like [[https://codeberg.org/notchoc/dwlmsg][dwlmsg]].
+
+Status information to stdout is currently disabled as dwl tends to freeze. For now, ~dwlmsg -w~ should act as a drop-in replacement.

+Note to [[https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/pertag][pertag]] users: apply [[https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/ipc/ipcpertag.patch][this]] for ipc tagsetting to work as expected
