Subject: [bug#66932] [PATCH] services: Add xremap service.
Date: Mon, 09 Dec 2024 01:56:34 +0000

Hello!

Looks like this got a little lost, but would love to have an xremap
service (I have a config I found which gives me nice emacs keys
everywhere).

From what I saw when I first looked at xremap, there's quite a lot of
syntax and possibilities. I guess the simplest thing is just something
that produces yaml from s-expressions without much logic, but maybe that
doesn't gain us much.

In any event, would like to have this as a starting point.

Ludo’: had you reviewed this at all do you remember, besides the
comment/suggestion above?

I don't know how this might work, sorry. It did seem more complicated to
do this without root, I believe by design of how such input grabbing
works (as one would hope, for security). A home service would indeed be
ideal, along with configuring as noted above, but I think both are quite
a bit more work.

Thanks for the patch, I haven't tried it but maybe I can just take the
actual service part and slap it in my config...
