Ivan MolodetskikhFullscreen refactor pt. 1: track pending vs. current fullscreen state for columns, avoid vertical jump when waiting for window to commit a new buffer.
#niri
Ivan MolodetskikhFullscreen refactor pt. 2: added un/fullscreen animations. This one involved quite a lot of moving parts actually, so looking for testing.
https://github.com/YaLTeR/niri/pull/2333
#niri
Ivan MolodetskikhFullscreen refactor pt. 3 turned out to be a refactor of a good chunk of core Smithay xdg-shell/layer-shell/session-lock logic, making it more correct. The fullscreen PR in niri now includes that Smithay refactor, and needs testing even more than before 
https://github.com/YaLTeR/niri/pull/2333#issuecomment-3263990200
Specifically, the refactor makes Smithay correctly track the last acked configure for each commit, also enforces the "must ack before committing first buffer" protocol rule.
#niri
Ivan MolodetskikhWith the fullscreen refactors in place, I got started on the thing that I wanted to do all along: maximize.
Niri didn't support normal Wayland maximize because it's very similar (yet slightly different) to our full-width columns—and can't be bound to our full-width state either. However, after plenty of requests, and thinking about it, I reconsidered. Henceforth, the maximize buttons and double-clicking on the titlebars will do the expected thing.
Details in PR: https://github.com/YaLTeR/niri/pull/2376
#niri
Ivan MolodetskikhMy Smithay refactors were merged: the big one mentioned above, plus a fix for popup stacking order (e.g. open popup, then open tooltip also from the toplevel itself), plus a fix for root popup grabs from Qt layer-shell surfaces. All of this along with fullscreen refactors and animations is now merged to niri main. (maximize is still wip)
#niri
Ivan MolodetskikhThere's been a long-standing request to add config includes to niri. They're useful for config organization, but also for custom desktop shells to be able to change colors without having to edit the main user's config.
Today I finished the first step towards this: a many-days-long refactor that makes the main config part, layout, mergeable, i.e., able to be combined from multiple parts. And building on this, per-output/workspace overrides.
https://github.com/YaLTeR/niri/pull/2449
Testing wanted here!
#niri
Ivan MolodetskikhOur config system is declarative, rather than command-like, which means that we parse the config into a tree of data types instead of reading lines and applying them one-by-one. This design requires a lot of work to properly support includes, but in turn we get atomic and selective reloading (if output part of the config didn't change, we don't override your transient output adjustments), better error messages and no problems with things like "spawn-at-startup" that should only work once.
#niri
Ivan MolodetskikhAfter several more days of work, I fully finished config includes. All config sections merge together, live-reloading watches all included files (even if they fail to parse), error messages work across files, documentation is written.
https://github.com/YaLTeR/niri/pull/2482
Once again, this needs testing! There must be NO breakage to existing configs, so if something breaks, I want to know about it to fix it.
#niri
Ivan MolodetskikhI merged config includes, along with per-output and per-workspace layout config overrides. Play around with them at your nearest niri-git package.

Also merged ignore-drm-device which should let you passthrough a GPU to VMs: https://yalter.github.io/niri/Configuration%3A-Debug-Options.html#ignore-drm-device
#niri
Ivan MolodetskikhAfter a detour to config includes and, again, several days/weeks of work implementing all edge cases and expected behaviors, true window maximize is ready and merged to main. Tricky cases like: windows requesting fullscreen and maximize after opening; windows failing to match the full maximized size; transparent windows with the niri border behind them.
https://yalter.github.io/niri/Fullscreen-and-Maximize.html
Give it a try! Ngl I mostly switched to maximize just because I'm too lazy to reach the keyboard for Mod+F.
#niri
Ivan MolodetskikhOne cool thing I noticed about true maximize is that apps like GIMP or Inkscape or Blender, that really want all available space, maximize themselves at startup, so you don't have to window-rule them manually in your config

#niri
Ivan MolodetskikhSmall change on niri-git for people using the foot terminal with CSD, or other apps that constrain their sizes to a grid: niri will now match the default column width to a preset width when a window opens. So opening foot sized "proportion 0.5" and then pressing Mod+R will switch you to the next preset width, even if foot actually opened slightly smaller to match its terminal grid. Before the change, the first Mod+R would pick the same "proportion 0.5" in this case and "do nothing".
#niri
Ivan MolodetskikhAlso, experimenting with this interaction tweak on a branch: what if dragging tiled windows horizontally scrolled the view instead of dragging them "out"? This makes it possible to scroll the view mouse-only without going through the Overview (the zooming gets quite tiring when it's frequent), and makes it possible to scroll the view touch-only. To drag the window out of the layout, you can still drag it downward.
#niri
Ivan MolodetskikhAdded a small "Quick Start" to the niri docs that gets you going with niri + DMS in three commands:
https://yalter.github.io/niri/Getting-Started.html#quick-start
Tested the Fedora ones on a fresh VM, worked out nicely, getting me into a session with a very functional desktop shell.
#niri
Ivan MolodetskikhCurrently in the middle of finishing up the Alt-Tab PR for niri: https://github.com/YaLTeR/niri/pull/1704
Got most things working as I'd like, though still plenty of fixes and clean-ups left. Fully live window previews with block-out-from support and fading title labels.
There's some interesting design differences compared to other desktops: on niri I expect it's common to have multiple terminals open, so Alt-Tab must go by windows (not by apps) and must show previews big enough to pick the right one.
#niri
Ivan MolodetskikhWe've hit 15k stars on the niri repo!! 
#niri
Ivan MolodetskikhJust merged Alt-Tab to main, shortly arriving at your nearest niri-git. Comes with plenty of ways to tweak it if you want [1], and a focus timestamp in the IPC [2] that lets shell devs make their own recent windows switchers.

#niri
Ivan MolodetskikhDid some work on the TTY backend in niri over the past few days. Merged PR for DisplayLink dock support, added "panel orientation" property read, and, based on cosmic-comp code, implemented the necessary logic to avoid screen blanking. Finally, both at niri startup and when switching TTYs, your screen won't flicker, as long as resolution/refresh rate stay the same.
Even when the screen does blank, it'll go faster, as there's now just one modeset instead of two (clear then draw frame).
#niri
Ivan MolodetskikhTook some fighting but I think I've managed to teach the new Alt-Tab to speak to the screen reader
#niri
Ivan MolodetskikhI finished and merged the horizontal drag interaction tweak from a previous post. It's very handy but can also be annoying when you want to move windows across monitors, so on mouse I restricted it to headerbar dragging (so, not Mod+LMB and not in the overview).
On touch however, it works for both headerbar dragging, and for Mod+Touch, so you can now easily scroll the view around.
I also added the thing where you can touch with another finger to switch between floating and tiling.
#niri
Ivan MolodetskikhDankMaterialShell folks set up builds for Debian, Ubuntu and OpenSUSE, so now it's super easy to try niri & DMS on those systems.
I added Ubuntu commands to the niri quick start guide: https://yalter.github.io/niri/Getting-Started.html
Debian and OpenSUSE here: https://build.opensuse.org/project/show/home:AvengeMedia:danklinux

Ivan MolodetskikhToday I'm releasing niri v25.11 with long-awaited config includes, Alt-Tab, true maximize, custom modes, and a bunch of other improvements! 
Enjoy the release notes :)

#niri
Ivan Molodetskikhfunny how while working on alt-tab i discovered that mouse scrolling on top of the DMS bar switches workspaces, which completely replaced any need i had for alt-tab, so i ended up never using it
this DMS bar scrolling feature also removed one of my main usecases for the overview
and then the new horizontal window drag gesture removed my other main usecase for the overview, so now i'm opening the overview quite rarely too
(both have their uses; just curious to watch my own habits shift)
#niri
Ivan MolodetskikhI've had one of those sessions today where I worked with a ton of random windows on a long workspace, while preparing slides for a uni scientific presentation. All kinds of various PDFs, file managers, InkScape, GIMP and so on.
Horizontal mouse headerbar drag to scroll the view was a lifesaver. Definitely a good choice adding this. Along with scrolling the view on DnD near the screen edge. Going through the overview, or always through the keyboard, would be very annoying.
#niri
Ivan Molodetskikhyuxqiu just improved the default GPU detection logic in Smithay, so niri-git now works out of the box on Asahi and Pinephone devices, without having to manually configure render-drm-device!
#niri
Ivan Molodetskikhi added the pointer warping thing from blender to when you drag the view around in niri with the mouse
hf with this new way to pass time during boring meetings
(on a more serious note this helps when you need to scroll further than the edge of your monitor allows)
also unrelated: merged optional config includes earlier today
#niri
Ivan Molodetskikhon niri-git, the nautilus rename popup now works properly with IMEs running
(and generally popups with text fields should work now)
#niri
Ivan MolodetskikhExperimenting with a restructure of the niri rendering code to uncurse it somewhat by getting rid of all complex impl Iterator chains and lifetimes, which also lets me remove some intermediate small Vecs. In essence, going from pull to push iteration.
I'm surprised that the result is consistently 2-3x faster than before. Wonder if it's the Vecs, or if inverting (massive) codegen'd iterators into a normal call stack passing a closure arg, providing the main benefit
#niri
Ivan MolodetskikhFinished the push-based rendering refactor, made a write-up here for the curious: https://github.com/YaLTeR/niri/pull/3113
It even ended up with a negative delta (+762 -780) which is always a W.
Btw I ran the comparison on my Eee PC and there the difference is even more extreme, like 8x faster rendering list construction (which is once again only a part of the total rendering time, and notably doesn't include actual rendering, but still nice).
