charset=UTF-8 Content-Transfer-Encoding: 8bit Implements a smooth sliding animation for the selection indicator in uniform_list pickers (e.g., command palette). When navigating with arrow keys, the selection now smoothly slides between items instead of jumping abruptly. Implementation details: - Created SelectionIndicator decoration using UniformListDecoration trait to render an animated overlay behind list items - Added tracking for previous selection index to enable smooth transitions between arbitrary positions - Clamped animation distance to 3 items max to prevent jarring long- distance animations when jumping via search results changes - Used 80ms cubic ease-out timing for natural, responsive feel - Suppressed per-item selection backgrounds in uniform lists to avoid dual-highlight visual conflict - Added reduce-motion support for accessibility - Fixed paint order in uniform_list so decorations render behind items The animation uses a wrapper div positioning approach to avoid layout issues with absolute positioning in decoration contexts. --- Cargo.lock | 1 + crates/gpui/src/elements/uniform_list.rs | 6 +- crates/picker/Cargo.toml | 1 + crates/picker/src/picker.rs | 151 +++++++++++++++++++---- 4 files changed, 129 insertions(+), 30 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index c69c844bad05a8..40cd87ac91abe7 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -12252,6 +12252,7 @@ dependencies = [ "schemars", "serde", "serde_json", + "settings", "theme", "ui", "ui_input", diff --git a/crates/gpui/src/elements/uniform_list.rs b/crates/gpui/src/elements/uniform_list.rs index a7486f0c00ac4e..7c56c6cdab5c85 100644 --- a/crates/gpui/src/elements/uniform_list.rs +++ b/crates/gpui/src/elements/uniform_list.rs @@ -544,12 +544,12 @@ impl Element for UniformList { window, cx, |_, window, cx| { - for item in &mut request_layout.items { - item.paint(window, cx);

Previously, animation would play while scrolling at the top and bottom edges, causing a jittery up-down or down-up visual effect. Now tracks the visible item range and excludes partially visible edge items from the "safe to animate" zone. When the new selection is outside the fully-visible range, animation is skipped and the indicator stays stationary while list content scrolls underneath. This creates smooth scrolling behavior at both boundaries: the selection indicator remains fixed at the edge position while the list content slides beneath it, matching natural list navigation UX. --- crates/picker/src/picker.rs | 27 ++++++++++++++++++++++++++- 1 file changed, 26 insertions(+), 1 deletion(-) diff --git a/crates/picker/src/picker.rs b/crates/picker/src/picker.rs index dd8bdd59299bb5..5c28a1713c35cb 100644 --- a/crates/picker/src/picker.rs +++ b/crates/picker/src/picker.rs @@ -164,6 +164,7 @@ pub struct Picker { item_bounds: Rc>>>, previous_selected_index: Option, selection_generation: usize, + last_visible_range: Rc>>, } #[derive(Debug, Default, Clone, Copy, PartialEq)] @@ -432,6 +433,7 @@ impl Picker { item_bounds: Rc::new(RefCell::new(HashMap::default())), previous_selected_index: None, selection_generation: 0, + last_visible_range: Rc::new(RefCell::new(0..0)), }; this.update_matches("".to_string(), window, cx); // give the delegate 4ms to render the first set of suggestions. @@ -548,7 +550,28 @@ impl Picker { let current_index = self.delegate.selected_index(); if previous_index != current_index { - self.previous_selected_index = Some(previous_index); + let visible = self.last_visible_range.borrow().clone(); + // The first and last items in the visible range may be only + // partially visible.

charset=UTF-8 Content-Transfer-Encoding: 8bit Add exhaustive unit tests for all animation state machines and pure logic functions introduced in the animations branch. Tests focus on behavior correctness, not visual rendering. Test coverage: - reduce_motion_setting: 6 tests for On/Off/System behavior, defaults, settings integration, and global function - picker: 14 tests for SelectionIndicator::animated_origin (reduce motion, visibility, clamping, boundaries) and is_fully_visible logic (safe range, scroll boundaries, list edges, empty cases) - dock: 10 tests for open/close state machine (set_open, reduce_motion skip, animation completion/cancellation, double operations, panel activation, generation tracking) - modal_layer: 11 tests for toggle/hide/show operations, animation lifecycle, reduce_motion skip, type safety, and state queries - utility_pane: 3 tests for slot mapping and dock position conversion All 44 tests pass. Uses GPUI test framework with proper async executor clock advancement for timer-based animations. --- crates/picker/src/picker.rs | 142 ++++++++++ crates/settings/src/reduce_motion_setting.rs | 106 +++++++ crates/workspace/src/dock.rs | 284 +++++++++++++++++++ crates/workspace/src/modal_layer.rs | 248 ++++++++++++++++ crates/workspace/src/utility_pane.rs | 35 +++ 5 files changed, 815 insertions(+) diff --git a/crates/picker/src/picker.rs b/crates/picker/src/picker.rs index bcb9d52e718c35..be394ac6d3dd2e 100644 --- a/crates/picker/src/picker.rs +++ b/crates/picker/src/picker.rs @@ -984,6 +984,148 @@ impl Picker { } } +#[cfg(test)] +mod tests { + use super::*;

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes three critical issues in animation state management: 1. Silent error handling: Changed modal_layer.rs spawn_in pattern from .ok() (which discarded errors) to upgrade() pattern that properly handles entity lifecycle 2. Integer overflow safety: Replaced += 1 with wrapping_add(1) for animation_generation counters across modal_layer, dock, and utility_pane to prevent panic on usize overflow 3. Magic number elimination: Extracted animation duration constants (OPEN_DURATION: 150ms, CLOSE_DURATION: 100ms) and MODAL_SLIDE_OFFSET (-6.0px) for maintainability Also removed summary doc comments per CLAUDE.md guidelines (comments should explain "why", not "what") and added explanatory comments for non-obvious animation_generation increment pattern that prevents stale close tasks from interfering with new animation cycles. --- crates/workspace/src/dock.rs | 8 +++- crates/workspace/src/modal_layer.rs | 43 +++++++------------ crates/workspace/src/utility_pane.rs | 63 +++++++++++++++++++++++++++- 3 files changed, 82 insertions(+), 32 deletions(-) diff --git a/crates/workspace/src/dock.rs b/crates/workspace/src/dock.rs index 27aa3576e51002..a5951ae8cdb776 100644 --- a/crates/workspace/src/dock.rs +++ b/crates/workspace/src/dock.rs @@ -18,6 +18,8 @@ use ui::{prelude::*, right_click_menu}; use util::ResultExt as _; pub(crate) const RESIZE_HANDLE_SIZE: Pixels = px(6.); +const DOCK_OPEN_DURATION: Duration = Duration::from_millis(150); +const DOCK_CLOSE_DURATION: Duration = Duration::from_millis(100); pub enum PanelEvent { ZoomIn, @@ -497,6 +499,7 @@ impl Dock { return; } self.is_open = true; + // Prevents stale close tasks from clearing state after a new open/close cycle has begun. self.animation_generation = self.animation_generation.wrapping_add(1); if let Some(active_panel) = self.active_panel_entry() { active_panel.panel.set_active(true, window, cx); @@ -516,7 +519,7 @@ impl Dock { let close_generation = self.animation_generation; self._close_task = Some(cx.spawn(async move |this, cx| { cx.background_executor() - .timer(Duration::from_millis(100)) + .timer(DOCK_CLOSE_DURATION) .await; if let Some(this) = this.upgrade() { this.update(cx, |dock, cx| { @@ -804,6 +807,7 @@ impl Dock { } fn visible_entry(&self) -> Option<&PanelEntry> { + // Panel remains visible during close animation so it can animate out smoothly. if self.is_open || self.is_closing { self.active_panel_entry() } else { @@ -997,7 +1001,7 @@ impl Render for Dock { dock_div .with_animation( ("dock-anim", animation_generation as u64), - Animation::new(Duration::from_millis(if is_closing { 100 } else { 150 })) + Animation::new(if is_closing { DOCK_CLOSE_DURATION } else { DOCK_OPEN_DURATION }) .with_easing(ease_out_cubic), { let position = self.position; diff --git a/crates/workspace/src/modal_layer.rs b/crates/workspace/src/modal_layer.rs index e88cf5e8c7b025..1915213f295dd0 100644 --- a/crates/workspace/src/modal_layer.rs +++ b/crates/workspace/src/modal_layer.rs @@ -9,6 +9,7 @@ use ui::prelude::*; const MODAL_OPEN_DURATION: Duration = Duration::from_millis(150); const MODAL_CLOSE_DURATION: Duration = Duration::from_millis(100); +const MODAL_SLIDE_OFFSET: f32 = -6.0; #[derive(Debug)] pub enum DismissDecision { @@ -100,13 +101,6 @@ impl ModalLayer { } } - /// Toggles a modal of type `V`.
