2025-11-16Implement recent windows switcher (Alt-Tab)rustN00b
Historic commit description log: The MRU actions `focus-window-mru-previous` and `focus-window-mru-next` are used to navigate windows in most-recently-used or least-recently-used order. Whenever a window is focused, it records a timestamp that be used to sort windows in MRU order. This timestamp is not updated immediately, but only after a small delay (lock-in period) to ensure that the focus wasn't transfered to another window in the meantime. This strategy avoids upsetting the MRU order with focus events generated by intermediate windows when moving between two non contiguous windows. The lock-in delay can be configured using the `focus-lockin-ms` configuration argument. Calling either of the `focus-window-mru` actions starts an MRU window traversal sequence if one isn't already in progress. When a sequence is in progress, focus timestamps are no longer updated. A traversal sequence ends when: - either the `Mod` key is released, the focus then stays on the chosen window and its timestamp is immediately refreshed, - or if the `Escape` key is pressed, the focus returns to the window that initially had the focus when the sequence was started. Rename WindowMRU fields Improve window close handling during MRU traversal When the focused window is closed during an MRU traversal, it moves to the previous window in MRU order instead of the default behavior. Removed dbg! calls Merge remote-tracking branch 'upstream/main' into window-mru Hardcode Alt-Tab/Alt-shift-Tab for MRU window nav - Add a `PRESET_BINDINGS` containing MRU navigation actions. `PRESET_BINDINGS` are overridden by user configuration so these remain available if the user needs them for another purpose - Releasing the `Alt` key ends any in-progress MRU window traversal Remove `focus-window-mru` actions from config These actions are configured in presets but no longer available for the bindings section of the configuration Cancel MRU traversal with Alt-Esc Had been forgotten in prior commit and was using `Mod` instead of `Alt` Rephrase some comments Fix Alt-Esc not cancelling window-mru Merge remote-tracking branch 'upstream/main' into window-mru Lock-in focus immediately on user interaction As per suggestion by @bbb651, focus is locked-in immediately if a window is interacted with, ie. receives key events or pointer clicks. This change is also an opportunity to make the lockin timer less aggresive.

For now it just puts up thumbnails for existing windows in MRU order. Added MRU texture cache + simplifications Working version Removed previous Mru code Tidy up Action names Added Home/End bindings Merge remote-tracking branch 'upstream/main' into window-mru-ui Add scope and filtering to Mru window navigation Feed todo list Merge remote-tracking branch 'upstream/main' into window-mru-ui Clippy: Boxed the focus ring The UI object doesn't get moved around much so it isn't clear if this actually important. Boxing keeps clippy happy because of the size difference between an Open vs a Closed MRU UI. Bump rust version to 1.83 Avoids getting yelled at by clippy for using features that weren't yet available in 1.80.1 Applied clippy lints Fix MruFilter::None conversion MruFilter variant was getting ignored cargo fmt Update rust tool chain in CI Had only been updated in Cargo.toml, this causes build failures on Github Support changing Mru modes with the Mru UI open Fix texture cache optimization When the Mru parameters were changed while the MruUI was open, the texture cache is rebuilt but attempts to reuse existing Textures that are still usable in the updated Mru list. The index of the retained texture could be miscalculated and resulted in the wrong texture being used for a given window Id. Make MruAdvance available as a Bind action For consistency, MruAdvance bindings are carried over when the MruUI is open. Merge remote-tracking branch 'upstream/main' into window-mru-ui Preset binds added as a source for MRU UI binds Surprisingly the status prior to the patch should have prevented the UI bindings to advance through the Mru list from working properly. Use iterators to find bindings This allows the caller, eg. `on_keyboard` to choose the full list of bindings that should be searched through by composing iterators. Prior to the change the PRESET_BINDINGS were always included regardless of caller. With this approach, `on_keyboard` can add in the MRU_UI- specific bindings if it detects that the MRU UI is open. Make scope and filter optional in mru-advance This avoids unexpected behavior when navigating MRU with a filter, e.g. App-Id, with arrow keys for instance, which would result in changing navigation to ignore the app-id filter. With the change, mru-advance has an optional scope and filter that allows a key bind to leave the current navigation mode unchanged. Add title under window thumbnails - Reworked the texture cache to use TextureBuffer-s instead of BakedBuffer. - Add convenience methods to access TextureCache content. Some tidying up. Fade title out if it doesn't fit in available size Add bindings to change the MruScope Fix panic rendering title when cairo surface was busy Also avoid interpreting markup in window titles. Bring branch in line with window-mru-ui-squashed Add navigation animation in MRU UI Only handles motion between thumbnails Add thumbnail close animation For now, the animation only tracks when the corresponding window is closed. Add animations on filter and scope changes Add open/close animation to MRU Ui Merge remote-tracking branch 'upstream/main' into window-mru-ui Fix animations on scope/filter changes Previous implementation would evict wrong textures from the cache. And get thumbnail animations wrong. Merge remote-tracking branch 'upstream/main' into window-mru-ui Fix panic on change of scope/filter when Mru list is empty. Add doc comment to method that could trigger a panic Simplify thumbnail ordering logic Improve scope/filter change animations - direction is no longer a factor when an Mru UI is opened (previously the first thumbnail would be the currently focused window when moving in the "forward" direction, and when moving in the "backward" direction the focused window would have its thumbnail last in the list. This made animations kind of confusing when switching scopes or filtering. The updated version always places the thumbnails in most recent focus order. So when the MRU UI is brought up in the "backward" direction, the last thumbnail in the MRU list starts selected. - closing animations no longer use the view referential, but use the output referential instead. This makes disappearing thumbnails appear stationary on screen even if the view is moving. This tends to look less confusing than the previous approach. Applied clippy lints Preserve scope during fwd/backward navigation Change preset keybinding declarations from const to static Add thumbnail selection animation This is still very much a work in progress: - the focus ring is not shown until the animation completes - if the tile is resized during the animation, the net effect looks pretty bad because proportions skip directly to those requested instead of transitioning smoothly. Both points should be addressed by using regular tile rendering to an OffscreenBuffer but I haven't much success there. Merge remote-tracking branch 'upstream/main' into window-mru-ui Fix niri-config parse test Use OffscreenBuffer to render ThumbnailSelection animation todo: fix thumbnail destination if the target workspace is being swapped. Handle workspace switch during thumbnail select animation Close Overview when MRU UI is opened Add configuration option to disable MRU UI Make mod-key for MRU UI configurable Avoid collecting MRU UI bindings on each input Bindings are cached when first accessed, the cache is invalidated whenever the configuration changes. Close MRU UI when Overview is opened Merge remote-tracking branch 'upstream/main' into window-mru-ui Fix MRU UI opened bindings always active Remove mru-advance from actions available for config keybind Because the MRU UI assumes that all key-bindings use the mod-key defined in for `recent-windows`, behavior can be disconcerting if arbitrary keybindings are allowed in the configuration (e.g. UI opens and immediately closes because the mod-key is not being held). Include focus timestamp in Window IPC messages Timestamps are serialized as time::SystemTime, which in JSON form is represented as *two* fields, secs and nanos. Merge remote-tracking branch 'upstream/main' into window-mru-ui Only do Thumbnail Select Anim if MRU UI stayed open long enough Threshold is hard coded in window_mru_ui.rs (250ms). Merge remote-tracking branch 'upstream/main' into window-mru-ui Add a few WindowMru tests Forward Mod-key release when closing MRU UI Merge remote-tracking branch 'upstream/main' into window-mru-ui Remove extraneous thumbnail motion on Mru filter change Fix missing alpha in Mru thumbnail open animation Add Mod+h and Mod+l bindings for MRU navigation Change CloseWindow binding in MRU to Mod+Shift+q Keep MRU UI on display it was initially opened on Bump up the MRU IU selection anim threshold Allow MRU thumbnail selection with mouse pointer Allow MRU thumbnail selection using touch Needs testing, Idk if this works for lack of a touchscreen. Fix missing fade-out animation for thumbnails on MRU UI close Merge remote-tracking branch 'upstream/main' into window-mru-ui Make thumbnail selection animation optional Merge remote-tracking branch 'upstream/main' into window-mru-ui Fix niri-config parse test case Add shortcut to cycle through MRU scopes - added MruCycleScope action to trigger cycling - added an indication panel to show the current scope - recall previous scope when opening the MRU UI Merge remote-tracking branch 'upstream/main' into window-mru-ui Improve MRU thumbnail scaling Prior to the commit, thumbnails were just 2x downscaling of their corresponding window. Now they are also scaled based on the relative height of the window on its output display. This avoids having a thumbnail taking up the entire screen on the display where the MRU UI is displayed. Merge remote-tracking branch 'upstream/main' into window-mru-ui Use resolved window rules for thumbnails Previously parameters such as the corner-radius didn't follow the general config and used an MRU UI specific default. Align thumbnail size and position to physical pixels clarify param names in generate_tile_texture Revert MSRV 1.83 Close MRU UI on click/touch outside of a thumbnail MRU - display window title under all thumbnails MRU - revert to pre-defined thumbnail corner radius MRU - Removed thumb title font size adjustment This didn't look as if it was necessary. (unscientific assesment) MRU - reverted to Mod+Q to quit selected thumbnail Merge remote-tracking branch 'upstream/main' into window-mru-ui MRU - Update focus ring when moving mouse over a thumbnail restore code that went missing switch focus timestamp to monotonic time We don't want the monotonicity of SystemClock here. Instant itself isn't serializable, but our monotonic clock timestamps are, and they are consistent across processes too. axe thumbnail close animation I'm still not quite convinced about it. Maybe we'll reintroduce it later with better architecture; for now though, it causes quite a bit of complexity. minor cleanups remove unnecessary option replace open animation with delay Avoids flashing the whole screen for quick Alt-Tabs. Duration taken from GNOME Shell. make mod key different in nested replace SelectedThumbnail with MappedId don't hide focus ring during alt tab wip refactor everything and render live windows rename some constants replace focus ring with background + border extract thumbnail constructors reimplement title fade with a shader reimplement ui fade out on closing fix preview scaling add min scale for very small windows add keyboard focus for mru fixes activating alt on target window revert/simplify pointer code changes fixes mouse not clamped to output when in alt-tab; should fix touch going through move touch handling to below screenshot ui remove unneeded touch overview grab code rename to mru.rs move mru tests into separate file also close mru when clicking on other outputs roll back no longer necessary event filtering rework mru keyboard binds convert some regular binds to MRU binds hide window title when blocked out verify that mru bind uses a keyboard key improve selection visibility & indicate urgency freeze alt-tab view on pointer motion add WindowFocusTimestampChanged event, separate struct for Timestamp minor cleanups scope panel fixes simplify scope cycling honor geometry corner radius don't trigger focus-follows-mouse in the MRU remove unnecessary argument cache backdrop buffers remove unnecessary mru close allow to screenshot the mru support bob offset improve mru redraws pass config instead of options add open-delay-ms option add highlight options rename window-mru-ui-open-close to recent-windows-close add preview options fix scope change and remove window delta anim improve unselected scope panel text contrast move panel back up so it doesn't overlap the screenshot one rename preview to previews in config render highlight background with focusring fix highlight pos rounding add highlight corner-radius setting remove allocation from inner render use offscreen for mru closing fade make scope only affect MRU open otherwise you can't change scope at runtime easily replace todo with fixme include title height in thumbnail under remove cloning from set scope/filter remove animate close todo update field name in mapped remove commented out closing thumbnails I decided not to do this for now. rename filter from None to All and skip in knuffel None is confusing with Option write docs make inactive urgent more prominent remove reopen from scartch todo explicitly mention app id in filter make scroll binds work in the mru add fixmes don't select next window when nothing is focused add missing anim config merge fixes replace click selection with pointer motion + confirm simplify close mru ui call rename mrucloserequest variants mru confirm fixes support tablet input mru commit cleanups remove most mru commit calls they didn't actualy do anything as implemented.

2025-06-18Fix typos (#1822)Baily
* Fix: Correct typo in xwayland module and update documentation This commit includes several improvements: 1. **Code Fix (clippy):** - I corrected a typo in `src/utils/xwayland/mod.rs` from `OFlags::WRONGLY` to `OFlags::WRONLY`. This was identified by `clippy` during the build process. 2. **Documentation Updates:** - **README.md**: - I clarified the sentence about finding help in the Matrix channel to be more inviting for new users. - I corrected a future date typo in the Media section for an interview (June 2025 to June 2024). - **wiki/Getting-Started.md**: - I changed the Russian month "мая" to "May" in an example output for better international readability. - I improved keybinding notation for monitor focus/move keys (e.g., Mod+Shift+H / J / K / L) to avoid ambiguity. - I updated `apt-get` to `apt` in Ubuntu dependency installation commands for modern practice. No new typos were found by `typos-cli` in this pass. * Revert README&GS.md to previous version * Apply rustfmt --------- Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>
