Hi! I enjoy #Rust and #GNOME. I play a bit of Quaver and osu!. Apparently a Wayland compositor author now.

Trying out Tuba again and wow, I'm quite impressed! The login flow was as quick and painless as it gets, and the client feels quite polished.

ported Identity and Video Trimmer to the new css stuff (well, ported is a strong word, there's like 10 lines of css there), so now Video Trimmer is ready for accent colors!
(yeah yeah i know that window needs a design overhaul but for now im too lazy)

My Wayland compositor, niri, turns one today! :ablobcatrave:
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

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!

also in an act of severe procrastination i decided to try drawing a diagram of the redraw state machine: https://github.com/YaLTeR/niri/wiki/Redraw-Loop

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!

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).

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.

Oops, 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!

Apparently there's a cool Pango flag that enables subpixel glyph positioning which makes things scale smoother and improves kerning! Thanks Benjamin (the GTK maintainer) for the suggestion

niri v0.1.7 is out with fractional scaling, window screencasts and many smaller improvements!

Fixed transparency support. Turns out the BGRA format should've been in a separate pod, rather than as a choice in the same pod. Should've looked at Mutter code sooner as usual..

Icons are missing in the portal dialog because apparently Shell keeps track of Wayland app ID to .desktop file mapping internally and returns the .desktop file name to the portal for it to get the icon. Which is a bit too much effort for me to replicate for now. 😅

Phew, finished the initial implementation of window screencasting in niri! Complete with stream resolution change on window resizing.
Some details are still iffy regarding frame timing and frame callbacks, especially to obscured windows, but it *should* work decently fine for now.

So it turns out that changing PipeWire screencast stream resolution on the fly is actually not that hard! Which is great news because it's required (or at least very desirable) for implementing window screencasting.

Over the past few weeks I've been working on fractional scaling for niri. A simple implementation took about a day, but to do it *properly* I had to refactor the entire layout code to work in floating-point.
The result is well worth it though. Borders, gaps and windows are always physical-pixel aligned, and not restricted to integer logical pixel positions. There's no blur or position-dependent +-1 px jank. Fractional-scale-aware clients remain crisp at any scale.

visual tests are such a lifesaver, so glad I stole that idea from osu!lazer
