Decided to try writing a Wayland compositor for fun.

I'm working on an "event stream" IPC for niri where you get notified about events as they happen. For example, "workspace switched" or "keyboard layout changed".
To give it a good test, I actually started implementing native niri support in Waybar. You can give it a try too: https://github.com/YaLTeR/niri/pull/453#issuecomment-2317110904
I finished the initial event stream IPC implementation for niri. My Waybar fork implements a decent amount of the modules niri/workspaces, niri/window, niri/language. Please give that a try, also anyone who makes IPC scripts or bars please give a try to the event stream IPC itself so we can find any design flaws before merging.
The PR you will need: https://github.com/YaLTeR/niri/pull/453#issuecomment-2321730996
Waybar fork is linked from there.

The other day, Christian Meissl finished updating and publishing the libdisplay-info bindings [1]. This is quite exciting because, unlike edid-rs, it can parse the manufacturer/model/serial from pretty much any monitor.
So, today I spend a few hours integrating the manufacturer/model/serial monitor addressing all throughout niri: config, IPC, niri msg, screencast output selector. You should now be able to write/use "SomeCompany CoolMonitor 1234" everywhere!

Set up CI rustdoc publishing for niri-ipc: https://yalter.github.io/niri/niri_ipc/
This has the entirety of the niri IPC documented, including the new event stream events.
After the Waybar maintainer speedran merging my niri modules and releasing, I would feel bad delaying any longer, so here's niri 0.1.9
Event stream IPC for bars, better window resizing, properly named outputs, on-demand VRR, out-of-the-box fix for NVIDIA flickering, and other improvements!

Over the past 2 weeks I've been slowly but surely working on the interactive move niri PR [1] by @pajn. It's already got me to fix quite a bit of tech debt in the layout code, which is cool.
The PR is still rough around the edges, but mostly works, and I switched to running the branch on my own systems to give it thorough testing.
(also no, this is not the Floating Layer yet, though it's a good step towards that)
Attaching a video of what it looks like rn

Made interactive move work on touch (and resize too while I was at it), didn't need that many changes actually
Added a bit of rubberbanding before the window is "dragged out" of the layout. Should help avoid unintended layout changes.
Along with a few more fixes I did, I think interactive move should be good to merge? It's not 100% perfect and jank free, but I'm fairly sure I got all the important things done. Will give it some more testing.

Suddenly, @drakulix showcasing the Cosmic session running on, among other compositors, niri! On the big screen at the Ubuntu Summit
-
somehow this touch moving under stationary pointer works better than i expected
(yes trying to do a precise left click with an elbow was difficult)
By the way! I'll be giving a talk at RustCon in Moscow on December, 6!
Wherein I will briefly describe what a Wayland compositor is, and then show several testing and profiling workflows that I've been using to keep niri stable, robust and performant.
(The invitation to submit a talk was completely unexpected, guess niri found its way into the right eyes.
)There will be a recording, though in Russian.

Interactive window moving, laptop lid and tablet mode switch binds, mouse and touchpad scroll speed setting in today's niri v0.1.10 release!
https://github.com/YaLTeR/niri/releases/tag/v0.1.10
Also, niri-ipc is now on crates.io, but keep in mind that it will not be Rust-semver-stable: https://crates.io/crates/niri-ipc

Added scaffolding for layer rules, along with a block-out-from rule. Now you can finally block notifications from screencasts!
Though, layer-shell surfaces don't have a "geometry" so if they have shadows or transparent padding, all of that becomes solid black, since niri has no way to know where the "actual content" of the layer surface is (that's what geometry is for windows).

Somehow, a small change for tests escalated into trying to completely refactor how animation timing works in niri. And right now I find myself at the exact opposite of this picture. Unfortunately, time has not stopped and is causing problems
-
Like three complete refactors later, I think it's... working? For real this time? No weird issue is gonna sneak up that undermines the whole design?
Nothing seems to have caught on fire after one more day of personal testing and one more day in main. So here's a technical page I wrote about the the new niri animation timing design and its motivations: https://github.com/YaLTeR/niri/wiki/Animation-Timing

Today I merged a PR by FluxTape which adds "always empty workspace before first" to niri. At the surface this is just a simple config flag with obvious behavior, but it's actually full of edge cases! Things like which workspace to focus at startup. The code refers to workspaces by index in many places, and those all shift when you suddenly insert an empty workspace at index 0.
Took several days to catch them all even with our randomized tests, but I think it should be good now.
