- New crates/renamr-core/src/history module: HistoryBatch/HistoryEntry
records, revert_batch() moves files back to their original paths
(skip-on-conflict, same policy as rename::execute_renames; recreates a
deleted destination folder defensively), push_batch() maintains a
most-recent-first log capped at 50 batches. A partial port of the idea
behind net.filebot.HistoryDialog, as a flat undo stack rather than a full
session/element log. 6 new tests.
- New src-tauri/src/history.rs: persists the log as history.json in the OS
app-config directory (same location as settings.json). execute_rename now
takes an AppHandle and calls history::record_batch after every rename,
recording only the items that actually got renamed. Two new commands:
list_rename_history and undo_rename_batch.
- Frontend: the History button (previously a no-op) now opens a panel
listing past rename batches with a timestamp, file count, and the
old-name/new-name pairs, each with an Undo button. Undoing reconciles any
currently-loaded item back to its pre-rename path/name, same pattern as
post-rename reconciliation.
- Verified via cargo test (45 total)/check + npm build + a full Playwright
pass: loaded mocked files, renamed them, opened History, undid the batch,
and confirmed both the UI and the (mocked) backend state matched at every
step.
