Hmm...  Looks like a unified diff to me...

|Subject: [PATCH] Activate a window in response to _NET_ACTIVE_WINDOW
|
|By default, dwm response to client requests to _NET_ACTIVE_WINDOW client
|messages by setting the urgency bit on the named window.
|
|This patch activates the window instead.
|
|Both behaviours are legitimate according to
|https://specifications.freedesktop.org/wm-spec/wm-spec-latest.html#idm140200472702304
|
|One should decide which of these one should perform based on the message
|senders' untestable claims that it represents the end-user. Setting the
|urgency bit is the conservative decision. This patch implements the more
|trusting alternative.
|
|It also allows dwm to work with `wmctrl -a` and other external window
|management utilities
