Build the UI shell: slot registry, layout persistence, OpenTUI/React components - #53
Merged
Conversation
…components Implements Task 1.14 (Req 6.1-6.5, 7.3; design.md sections 8, 9, 16): - Add react/@opentui/core/@opentui/react to packages/core only, with jsx: react-jsx / jsxImportSource: @opentui/react on the root tsconfig so both bun test and a whole-repo tsc --noEmit stay clean. - ui/slotRegistry.ts: an ordered per-slot view registry backing tecode.ui.registerView, with last-wins duplicate handling, lazy entries seeded from manifest-declared pendingViews, a never-throwing activateExtension hook for on-demand activation, the activityBar.item <-> sidebar.view pairing helper, and the statusBar.item side/priority sorted-enumeration helper. - ui/layoutState.ts: debounced, serialized persistence of sidebar/panel visibility+size and the active view to state.json, with injectable fs/timer seams, non-blocking load, and parse-failure-keeps-last-good semantics; host/paths.ts grows getUserLayoutStatePath(). - ui/theme.tsx, ui/focus.tsx, ui/components.tsx: ThemeProvider/useTheme over the existing base palette, ContextFocusTracker/useFocusTracking bridging OpenTUI's focus events into the context-key store, and minimal List/Tree/Input/Tabs plus a RegisteredView bridge from @tecode/api's React-free ComponentType to real React elements. - ui/shell.tsx: Shell/ActivityBar/Sidebar/EditorArea/Panel/StatusBar, wired to the slot registry and layout state, with workbench.view.<id> commands kept in sync with known sidebar pairs. - api/create.ts now wires tecode.ui.registerView/useTheme/List/Tree/ Input/Tabs to the real slot registry and components instead of the Task 1.13 stub; api/stubs.ts drops the now-superseded UI stub. Headless UI tests use @opentui/core's real testing renderer (createTestRenderer, wrapped by @opentui/react's testRender) for actual cell-grid snapshots via captureCharFrame(), not a fallback.

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk:🟡 Moderate · up to This PR adds the UI shell, view registration, and persisted layout state, but the current implementation can render stale views, fail to resolve the declared UI dependency in tests, crash or preserve incorrect state when switching views, and overwrite user layout changes during startup.

TabsのuseEffectはoptionsの変化を追跡しません。
optionsは毎レンダーで新しい配列になり、<tab-select>の再構成でタブ内部の選択位置が初期化される可能性があります。しかし effect の依存配列はselectedIndexだけです。activeIdが同じままタブ一覧だけが変わった場合、選択位置が復元されません。依存配列にtabs.lengthを加えるか、optionsをuseMemoで安定化してください。♻️ 修正案

Inline comments:
In `@packages/core/package.json`:
- Around line 10-12: Update the `@opentui/react` dependency from ^0.1.30 to a
released version that exports ./test-utils, and align `@opentui/core` to the
compatible version while preserving the existing dependency declarations.
In `@packages/core/src/ui/components.tsx`:
- Around line 47-52: RegisteredView で component を直接呼び出さず、React の要素として JSX
描画するよう更新してください。ビュー切り替え時にフック状態を分離するため、Sidebar の RegisteredView には view.id、Panel の
RegisteredView には active.id をキーとして指定してください。
In `@packages/core/src/ui/layoutState.ts`:
- Line 305: Update the load flow around coerceLayoutState so fields modified by
update() before loading completes are tracked and excluded from applying
persisted values; preserve those local values in memory and when flush() saves
afterward. Add a regression test covering delayed readFile(), update(), load
completion, and flush() to verify the updated field remains in both runtime
state and persisted data.
In `@packages/core/src/ui/shell.tsx`:
- Around line 62-97: Migrate useSlotViews, useSidebarPairs, and
useStatusBarItems from useEffect/useReducer subscriptions to
useSyncExternalStore, providing each hook’s slot-specific subscribe callback and
current snapshot getter. Ensure the snapshot is reread immediately after
subscription setup so changes occurring before subscription cannot leave stale
results, while preserving the existing filtering and registry access behavior.
In `@packages/core/src/ui/slotRegistry.ts`:
- Around line 404-413: Update the synthesized activityBar.item entry in the
pending sidebar handling to use lazy: true instead of false, preventing
duplicate registerView warnings while preserving ActivityBar rendering behavior;
update the corresponding slotRegistry.test.ts expectation to true.

…ce, registry warnings - RegisteredView now renders the registered component as a real JSX element instead of calling it as a plain function, so its hooks get their own fiber; Sidebar/Panel/ActivityBar key their RegisteredView by view id so switching views cleanly unmounts/remounts instead of reusing state across differently-registered components. - layoutState.ts tracks fields update() touches before the initial load settles and re-applies them after load()'s merge, so an update() landing mid-load can no longer be clobbered by the persisted file. - shell.tsx's slot-registry subscription hooks re-render once immediately after subscribing, closing the window between a component's render and its effect subscribing where a registry change could otherwise be missed. - The synthesized activityBar.item placeholder is now lazy, so the extension's later real registerView call no longer logs a spurious "View re-registered" warning. - Raised the @opentui/core and @opentui/react minimums to ^0.1.107 (the installed version) since ./test-utils was added after 0.1.30 on the registry; synced bun.lock. - Nitpicks: Tabs' selection-sync effect also depends on tabs.length, the focus.test.tsx no-tracker test asserts against an independent context service, RegisteredView's prop-passing test no longer requires an exact render count, slotRegistry.test.ts drops the redundant recording-log helper and gains a rejected-activation retry test, and listSidebarPairs's map fallbacks are explicitly typed.
