Funny enough, I just decided to take the plunge and try out Wayland
finally with Hyprland, as a sucker for eye candy. I do miss using Lisp
more (coming from lots of StumpWM time) and easy emacs keybindings
everywhere.

I'm using a package from a channel, I believe, of one of our
committers, who I'm cc'ing as I was just about to ask them about
upstreaming.

Works great on my end, thanks to them!

I could take this on mesa-updates as I was going to be doing some
updates so might as well take this. I'll add it locally and send a
message to the bug number. Part of my motivation was to be able to
upstream Hyprland as well.

If this fits better on another existing branch, please let me know,
someone.

I have this locally on my mesa-updates. I'll send a message to that
bug number.

I have this locally as well and will send some patches for review. It
took a bit more work, though the final result is pretty simple, it
needed a hidden cairo and a new cairo-with-documentation to build the
docs. I built up to icecat locally and all was good from what I could
see.

Sorry for any duplicate work, perhaps your version can add something
to mine.

I believe we'll need a more current version than the released wlroots
as well. Possibly others based on the channel I referenced above, but
the big update is libdrm and cairo, in terms of rebuilds.

Was this handled already in <https://issues.guix.gnu.org/68146> for
wlroots? Which has been merged.

Thanks for your efforts and helping get this conversation started! I
think we can handle the bigger updates on the mesa-updates branch. I
was planning on pushing that to get builds going once I send the cairo
patch and have people take a look at that. Despite the big changes,
I'm fairly confident in it since it seems pretty much everything we
need is built by default now.

And agreed that Hyprland has been pretty nice so far as my first step
into Wayland. Though if anyone can point me to the best way to get
emacs keys everywhere I will be forever thankful. Seems xremap can do
it (which we have packaged) except it doesn't pick up different
applications for where keys apply on Hyprland. I do miss in Stump how
easy that was right in the config.
