Ivan MolodetskikhOops, looks like niri had outstarred PaperWM on GitHub 🙈
PaperWM introduced me to (and made me fall in love with) scrollable tiling. It's a solid implementation on top of GNOME, so you get all the benefits of running a stable and well-supported DE (and Xwayland). PaperWM is also a very direct inspiration for many parts of niri!
Implemented the thing where you can toggle the mouse pointer on the screenshot after the fact (by pressing P). Gonna add a help panel here soon to remind you of this.
Much better
key repeat + scrollable tiling = fun
One of the niri users has contributed a gradient interpolation color space setting! Now you can do pretty gradient borders in srgb-linear, oklab and oklch (in all four hue directions).
I made a COPR for git builds of niri: https://copr.fedorainfracloud.org/coprs/yalter/niri-git
Apparently this is a thing you can do; relatively easily, even. It's fully automatic, triggers on a webhook from GitHub.
Thanks Michael (my4ng) from our Matrix channel for showing me the relevant docs and doing the initial work!
Spent a better part of today, but I've got dmabuf modifier negotiation fully working in my pipewire screencasting code in niri! This happens to finally fix screencasting on NVIDIA GPUs. Still haven't got any GStreamer pipeline working though, maybe needs a pipewire update.
Apparently, my AMD selects a BGRA format modifier that has two planes. Some out of band info I suppose. And on Intel a preferred BGRA modifier has three entire planes!
My Wayland compositor, niri, turns one today! 
Here's v0.1.8 with bind key repeat, screenshot UI pointer toggle, gradient color spaces, wlr screencopy v3 and output management, and lots of other improvements: https://github.com/YaLTeR/niri/releases/tag/v0.1.8
omg, my friend drew a birthday nirik 
i recorded a demo video for the focus-follows-mouse section to showcase it lol
Several days and a lot of hair pulling later, I *think* I got resize transactions working?? Maybe? Hopefully?
Resize transactions is when all windows that must resize together, resize together, with no mismatching frames in between. For example, all windows in a column must add up to the full screen height.
This requires correct configure acks on the client (looking at you, Blender) and very careful state update delaying and resize throttling on the compositor side.
narrator: there was still one case where it didn't work due to a bug
okay, surely this time it definitely works for all correctly written clients
Here's one mainly for people who disable animations: window closing now runs in a transaction with the other windows resizing. This means, no background flicker.
There's been another logo discussion in the niri Matrix room with some quite interesting concepts emerging. Here's one by Endg4me_ with edits by bluelinden and myself, and inspiration from a concept by ElKowar.
What do you think?
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).
Thanks to Christian Meissl's fix in Smithay, the git version of niri correctly shows nested pop-up menus in lxqt-panel. They also submitted a fix for invalid pop-up spawning to ironbar, which makes it work on Smithay compositors.
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.
>while testing, already found two uncaught regressions introduced in previous niri releases, and no issues with the refactor
This morning was my niri (-adjacent) talk! 
Went really well, got many interesting questions!
They promised us video recordings in a few days, so I'll post a link when I get it. Though of course the talk is in Russian.
