Since Emacs learned wayland last year, it can now become a wayland compositor.
Emacs is already a great window manager. Let us embrace this in the wayland
future, where managers become compositors.
In this short talk I would like to convince you that this is a good idea and get
you exciting about the possibilities. I then outline how to go about
implementing this idea.
Afterwards I would very much like to get a discussion started together.

# Discussion
## Notes
- Call to action - let Michael know if you know anyone else working on
something like this so they can collaborate and not duplicate
effort.
- Site (coming soon): perma-curious.eu
- I am an EXWM user and would be very happy to test your code! Looks great!
- I know of many people quitting EXWM because of the lack of active development. Your project could be a kind of revival!
- I would be interested to try it out. I'm on sway right now.
- What I mean is that people are moving to other WMs which work or are planned to work with Wayland
- sway.el might have something that could be used
- Feedback:
- Thank you very much for the talk and the work.
- Thank you for sharing your amazing work!
- Yes, thank you for the talk, looks really promising
- thank you for the talk
- Thanks and great job!
## Questions and answers
- Q: Are you using it as a replacement of EXWM?
- A: No, not yet, but I'm planning to.
- Q:Is this testable?
- A:
- Q: Have you considered contributing it to emacs core?
- A:
- Q:Question: this is wayland compositor in Emacs? What different with
XReprarent in X11 ?
- A:No, I planned it, but no. Does not handle file descriptors.
It's a compositor that talks to Emacs. etc. I don't know what
XReparent is; have to skip that.
- Q:What does it mean for emacs to be "a wayland compositor"? What
can the end users do with it?
- A:
- Q: How would multiple monitors be handled? Separate Frames?
- A:
- Q: Could you make it so you can restart emacs without loging out;
or switch to non emacs buffers while emacs is blocking: these are
the biggest issues with EXWM? Maybe in the future with a different
ui for non emacs buffers.
- A:
- Q:Did this project can implement *mirror* of buffer for Emacs
different window?
- A:
- Q:How does the single-threaded affects the project?
- A:
- Q:this technology need write wayland server? Can it works with
Gnome3 ?
- A:
- Q: Could there be a emacs-wayland-server and just connect with
emacsclient?
- A:
- Q: When you share your code, could you provide the equivalent of an
.xsession script for those who are on EXWM and want to test?
- A:
- Q: there have a demo to show this emacs-wayland-compositor, even it
buggy now? Just curious. ;)
- A:
- Q: So the current limitation is that buffer mirroring doesn't respect different widths/heights?
- A:(answered - transcript tbd)
- Q:Could you use some of this package with other walyand compositers
"probably not all of it" , sway, kde, river, gnome.
- A:(answered - transcript tbd)
- Q:Will Wayland support reach feature parity with EXWM in the future?
Will there be other tradeoffs?
- A:(answered - transcript tbd)
- Q: What is the biggest difference between Xorg and wayland that you
have found?
- A:(answered - transcript tbd)
- Q: Did you know EAF
<https://github.com/emacs-eaf/emacs-application-framework> ?
- Q: Do you have the code available somewhere (git repo)?
- <https://perma-curious.eu>
- Q: So the current limitation is that buffer mirroring doesn't respect different widths/heights?
Other discussions from IRC:
- If I understand correctly, this project is more like philosophy of EXWM, but it not based on X11, instead based on Wayland.
