Today: horizontal column movement is now animated!
Took the whole yesterday and a bit of today, but I've got window closing animations working! These turned out to be tricky because they need storing a snapshot of the surface render tree to draw once the app is gone.
Some apps may start destroying their subsurfaces before the main surface, like alacritty with its sctk CSD, making it very easy to miss parts of the window in the snapshot, and therefore in the closing animation.
Also, windows closing to the left no longer shift the view!

Definitely one of the most complex animations yet: window resizing.
Just the crossfade effect itself took a while to get working with all the window geometries and buffer offsets, and then there's the whole multiple window orchestration with Wayland's asynchronous nature. (I don't do animation transactions yet, that'll be a whole other level of complexity on top.)
Happy with the result though, and it's cool that it seamlessly works with block-out-from screencast.

Window movement across columns is now animated too!
These weren't complex per se, but very *finicky*. Spent quite a bit of time chasing down all the offsets and coordinates to add and subtract to avoid jumps, but it seems to all work well now!

All the animations, plus VRR, today in niri 0.1.5: https://github.com/YaLTeR/niri/releases/tag/v0.1.5
I also remade the demo video to showcase the animations and some of the newer features!

We've reached 1000 commits 😅 with an a bit of an anticlimactic one though

Another tricky feature, rounded corners! Took several days, but I believe I've got a pretty complete implementation.
You (manually) set the window corner radius and whether to force-clip the window. You can set radius per-corner to match GTK 3 apps. It works correctly with subsurfaces, blocked-out windows, transparency, gradient borders, resize and other animations.
Optimization-wise, opaque regions and even overlay plane unredirection work where possible!

Also, we've now got a little #niri setup showcase thread

https://github.com/YaLTeR/niri/discussions/325Added (stole from GNOME Shell as usual) a screen transition action, so now I can finally switch between dark and light in style
(of course, it works with blocked-out windows)

Okay, time for an actually useful feature: interactive mouse resizing (yes, finally). This was, as it goes, quite fiddly to implement, especially since niri has to negotiate with the window during the process.
I also added a double-resize-click (i.e. trigger a resize twice quickly) gesture to reset the window height or to toggle full width. Suggested by FreeFull on our Matrix and worked out very well! Really starting to feel quite nice with mouse.
(still no transactions yet)

nvim really taking its time processing all this 1000 Hz worth of resizing lol

Since I'm in a mouse gesture mood today: hooked up the horizontal touchpad swipe to Mod + middle mouse drag and omg it feels so good with the spring deceleration and all
(of course it also correctly avoids the touchpad scaling, so that when using the mouse gesture, the cursor location is always exactly anchored to the view position)

Now for something fun. I'm experimenting with the ability to set custom shaders for animations. Today I added custom shader support for window-close, which lets me make this cool falling down animation!
This is entirely optional of course, and there's no performance impact if you don't use it. Also, custom shaders, like the rest of the niri config, are live-reloaded, making it easy to play around with them.

Been fixing quite a bit of interactive resize jank and other small stuff since the last time, but also added custom shader support for window-open, thus completing it for all three main window animations (open, close, resize).
Now I didn't actually have any good idea of what I might want in a window open custom shader (I like the default), so I made a simple expanding circle animation to showcase it.

Niri 0.1.6 with interactive window resizing, rounded corners, named workspaces, mouse view scrolling, animation custom shaders, screen transition!
https://github.com/YaLTeR/niri/releases/tag/v0.1.6
Didn't realize quite how many release notes there would be this time; even had to use an extra level of headings. 😅

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.

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.

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.

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. 😅

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..

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

SOCIAL VIETATI UNDER 16: di chi è la COLPA e qual è la SOLUZIONE?
La vera soluzione non è tecnologica, ma passa per la responsabilizzazione dei genitori che forniscono l'accesso, possibilmente con una sana deterrenza economica.
Perché quando non si è in grado di esercitare la responsabilità individuale, la prospettiva è sempre la sorveglianza di Stato.Inutile dire che sono TOTALMENTE d'accordo con @lastknight

@BastilleBSD Take care of yourself. You deserve it, and we'll always be here, waiting for you, as we really appreciate what you do.

@fucinafibonacci le sensazioni provate fin dalle prime note di Innuendo sono indescrivibili, ricordo nitidamente quando ho inserito la prima volta il CD nel lettore il giorno della sua uscita

@peterkotrcka it is. Maybe it's the reason of the pimple.

@Pare ok, mettiamo "di parte". Per le risposte supposte oggettive, il problema però è la scuola (inteso come superiori, prima sarebbe impossibile. E non solo licei, anche istituti tecnici e professionali). È lì che si dovrebbe imparare a capire che una risposta oggettiva non la possiamo avere nemmeno in matematica (mi sono fatto una maglietta apposta).

@deadsuperhero@social.wedistribute.org I like this experiment. You're moving forward with an assumption in mind (that your brother's AI-generated version will be inferior to your own), and it should prove interesting, no matter the result :smile:

Negli ultimi giorni si parla di un cambiamento profondo nella finanza globale. #Amundi, il più grande #assetmanager europeo, sta riducendo l’esposizione ad alcuni asset statunitensi per aumentare la diversificazione verso Europa e mercati emergenti. Non è una fuga dagli Stati Uniti né un segnale di crisi, ma una scelta strategica legata a valutazioni elevate, valute e incertezze geopolitiche. Il focus è su equilibrio, gestione del rischio e adattamento a un mondo multipolare.

@fucinafibonacci @spettacoli assolutamente fantastico!
