Summary

  • Treat /__edit/batch responses with changed: false like the single-edit NoOpEditError path: keep pending edits and toast a warning instead of clearing the buffer.
  • Stop the Save bar from flashing success when a save rejects (no-op or failed write).
  • Add an inspector e2e covering the no-op batch save path.

Fixes #408

Test plan

  • Open Inspector, change a style (e.g. font size), Save — file updates and Save bar shows success
  • Select the same element, set the same style value again, Save
  • Confirm network response for /__edit/batch has changed: false
  • Confirm Save bar does not show success, pending edits remain, and a warning toast mentions the source file did not change
  • pnpm check / typecheck for @open-slide/core
  • Optional: packages/core inspector e2e a no-op batch save keeps pending edits and does not show success

Summary by CodeRabbit

  • Bug Fixes
    • Saving inspector edits now detects when the source file is unchanged.
    • Pending edits remain visible instead of being incorrectly marked as saved.
    • Success notifications are suppressed when no changes are applied.
    • Clear notices are shown when the source file has not changed.
    • Failed saves now preserve the unsaved state and report errors accurately.

Batch /__edit returned ok with changed:false; client
cleared pending and showed success. Match NoOpEditError.

Closes 1weiho#408

Review Change Stack

Walkthrough

Batch saves now detect unchanged source files, preserve pending edits, and show failure feedback instead of false success. Save controls retain the dirty state after failed commits. An end-to-end test covers the no-op save flow.

Changes

Batch no-op save handling

Layer / File(s) Summary
Batch edit result contract
packages/core/src/app/lib/inspector/use-editor.ts
applyEdits now returns edit results with a changed status.
No-op commit and history handling
packages/core/src/app/components/inspector/inspector-provider.tsx
Batch commits throw NoOpEditError when the source file is unchanged. History clears only after successful processing.
Save feedback and regression coverage
packages/core/src/app/components/inspector/save-bar.tsx, packages/core/src/app/components/panel/save-card.tsx, packages/core/e2e/tests/inspector.spec.ts, .changeset/batch-edit-noop.md
Save failures no longer resolve silently or set a false saved state. The end-to-end test verifies pending-edit retention and unchanged-source feedback. A patch changeset documents the behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to d0261

A partially failed batch save can still appear successful and clear undo history even though some edits remain pending, which may mislead users and reduce their ability to recover changes. The bounded inspector workflow is not merge-ready until this behavior is fixed or explicitly accepted.

Poem

A rabbit checks the batch once more
The unchanged file stays as before
Pending edits remain in sight
No false toast declares “all right”
The save path now reports what’s true

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep history when a batch has failed edits.

If any edit result fails, Line 779 clears history even though the failed edit remains pending. The user then cannot undo or redo that buffered edit. Clear history only when failures.length === 0.

Proposed fix
       refreshCount();
-      history.clear();
-      if (failures.length > 0) toast.error(`${t.inspector.saveFailed} ${failures.join('; ')}`);
+      if (failures.length > 0) {
+        toast.error(`${t.inspector.saveFailed} ${failures.join('; ')}`);
+      } else {
+        history.clear();
+      }
