Cancels the scheduled frame to avoid a double flush. Migrates the four rAF-stub blocks in ToolManager.test.ts to use the seam. Adds a targeted test locking in the contract: flush is synchronous and cancels the pending frame.

Production wires electronClipboardAdapter through the Editor constructor; tests pass an in-memory fake (done in the next commit). This matches VSCode's IClipboardService + TestClipboardService pattern and aligns with the existing "real class + fake boundary" convention already used for the NativeBridge seam in TestEditor. Changes: - Add ClipboardAdapter interface to lib/clipboard/types.ts - Add electronClipboardAdapter (production impl) in electronAdapter.ts — throws loudly if window.electronAPI is missing rather than silently dropping ops - ClipboardDeps.adapter required; Clipboard.#write / #read go through it - Editor constructor accepts optional clipboardAdapter override (defaults to electronClipboardAdapter), mirroring the existing bridge override pattern - Re-export ClipboardAdapter and electronClipboardAdapter from the clipboard barrel No behavior change — existing Clipboard.test.ts still stubs the global and passes. The next commit drops that stub in favor of DI. --- .../renderer/src/lib/clipboard/Clipboard.ts | 8 ++++---- .../src/lib/clipboard/electronAdapter.ts | 18 ++++++++++++++++++ .../src/renderer/src/lib/clipboard/index.ts | 2 ++ .../src/renderer/src/lib/clipboard/types.ts | 10 ++++++++++ .../src/renderer/src/lib/editor/Editor.ts | 10 ++++++++-- 5 files changed, 42 insertions(+), 6 deletions(-) create mode 100644 apps/desktop/src/renderer/src/lib/clipboard/electronAdapter.ts diff --git a/apps/desktop/src/renderer/src/lib/clipboard/Clipboard.ts b/apps/desktop/src/renderer/src/lib/clipboard/Clipboard.ts index 2c888e3d..5e553f79 100644 --- a/apps/desktop/src/renderer/src/lib/clipboard/Clipboard.ts +++ b/apps/desktop/src/renderer/src/lib/clipboard/Clipboard.ts @@ -10,6 +10,7 @@ import { Polygon } from "@shift/geo"; import { Validate } from "@shift/validation"; import { ValidateClipboard } from "@shift/validation"; import type { + ClipboardAdapter, ClipboardContent, ClipboardImporter, ClipboardPayload, @@ -35,6 +36,7 @@ export interface ClipboardDeps { readonly glyph: Signal; readonly selection: Selection; readonly commands: CommandHistory; + readonly adapter: ClipboardAdapter; } /** @@ -108,14 +110,13 @@ export class Clipboard { this.#pasteCount = 0; try { - if (!window.electronAPI) return false; const payload: ClipboardPayload = { version: 1, format: "shift/glyph-data", content, metadata: { bounds, timestamp: Date.now(), ...(sourceGlyph ? { sourceGlyph } : {}) }, }; - window.electronAPI.clipboardWriteText(JSON.stringify(payload)); + this.#deps.adapter.writeText(JSON.stringify(payload)); return true; } catch { return false; @@ -124,8 +125,7 @@ export class Clipboard { async #read(): Promise<{ content: ClipboardContent | null }> { try { - if (!window.electronAPI) return this.#internalState; - const text = window.electronAPI.clipboardReadText(); + const text = this.#deps.adapter.readText(); const native = tryDeserialize(text); if (native) return { content: native }; diff --git a/apps/desktop/src/renderer/src/lib/clipboard/electronAdapter.ts b/apps/desktop/src/renderer/src/lib/clipboard/electronAdapter.ts new file mode 100644 index 00000000..2870ce6c --- /dev/null +++ b/apps/desktop/src/renderer/src/lib/clipboard/electronAdapter.ts @@ -0,0 +1,18 @@ +import type { ClipboardAdapter } from "./types"; + +/** + * Production {@link ClipboardAdapter} backed by Electron's preload-exposed + * clipboard IPC (`window.electronAPI.clipboard*`).

"SystemClipboard" says what the thing is — the OS-level clipboard — and avoids collision with the Clipboard orchestrator class. 2. Drop the default-fallback in Editor's constructor Previously: systemClipboard was optional on the Editor constructor, defaulting to electronSystemClipboard when not provided. That's a test-hatch hanging off production code — the optional param only exists for tests. Now systemClipboard is required. The one production callsite (store.ts) passes electronSystemClipboard explicitly. TestEditor passes its InMemorySystemClipboard.
