    Finally finished making niri screencasts asynchronously wait for rendering completion before handing the buffer over to PipeWire. This fixes screencast flickering problems on NVIDIA setups.

    https://github.com/YaLTeR/niri/pull/2175

    This is not PW explicit sync; I can now finish that too (OBS and PW released their fixes), but it'll act more as an optimization on top of the current code (since only OBS can use it for now, and not on its Flathub build (PW is too old there)).

    Quite comprehensive desktop shell for niri released today: https://github.com/bbedward/DankMaterialShell

    Based on QuickShell; made by the same people who started the niri Discord server.

    Checking it out now, looks very cool! Though not without a few rough edges to iron out of course

        Yesterday dove into one of the older animation jank bugs in niri: quickly resizing a window back and forth would cause adjacent windows to jump. This problem is hard to trigger unless you're specifically trying to (then it's easy), but it was causing "downstream" problems for more complex actions.

        The fix was simple enough, but I imagined enough "interesting" cases around it and decided to write a whole bulk of tests. Check this out, all thanks to our layout and clock code!

          Merged the "window positions and sizes in IPC" PR. Please test and report if anything's broken or missing, we have time to fix it until the next release.

          https://yalter.github.io/niri/niri_ipc/struct.Window.html#structfield.layout

          Here's a quick quickshell test I threw together that draws floating windows as rectangles.

          Thanks yrkv for getting the PR mostly complete!

            With massive thanks to cutenice, we have a new wiki site!!! With good search!

            https://yalter.github.io/niri/

            Make sure not to miss the new Since: annotations

            The site uses Material for mkdocs, and we retained full compatibility with GitHub Wiki, meaning all existing links keep working.

            Also thanks everyone for several suggestions and test wikis in the GitHub discussion!

              Rearranged and expanded quite a bit the design principles page on the wiki: https://yalter.github.io/niri/Development%3A-Design-Principles.html

              Give it a read if you're curious about my thinking process about various niri behaviors and such

                          Fullscreen 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.

                            With 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.

                              My 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)

                                There'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!

                                  There'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!

                                  Our 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.

                                    After 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.

                                    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.

                                      I merged config includes, along with per-output and per-workspace layout config overrides. Play around with them at your nearest niri-git package.

                                        After 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.

                                        Give it a try! Ngl I mostly switched to maximize just because I'm too lazy to reach the keyboard for Mod+F.

                                          One 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
