fix(web): group composer undo the way the Lexical composer did by chrisdeeming · Pull Request #14674 · pingdotgg/t3code

chrisdeeming · 2026-10-01T22:30:59Z

Problem

Since the move from Lexical to Tiptap, one Cmd+Z in the composer can undo far more than the last action. Tiptap uses ProseMirror's history defaults: a 500ms group delay with adjacent edits merged. So typing, a paste and more typing in one burst undo together. To reproduce, type see , paste pasted text, type ok within a second, then undo once: the whole draft is gone. Lexical's history started a new step whenever the kind of change switched, with a one-second delay.

Change

A dispatch middleware closes the history group when the change kind switches between inserting, deleting and anything else (pastes, drops, cuts, store rewrites). The group delay is one second, as in Lexical. The composer's own paste handler takes every text paste before ProseMirror's paste path can tag it, so it now tags its transaction as a paste itself.

Scope and approval

A regression from the Lexical-to-Tiptap replacement. Julius reviewed this exact change in #12452, which it is split out of, and found the paste-tagging gap that is fixed here (#12452 (review)).

Verification

vp test run apps/web/src/composer-undo-grouping.test.ts: 6 passed. The tests use a real ProseMirror history plugin and cover typing, deleting, switching between them, and a paste tagged by the same helper the composer's paste handler uses.
Targeted lint, format check and the web typecheck pass.
In the web client I ran the reproduction above: real character transactions, a real paste event through the composer's paste handler, then one undo.

Before (main): one undo empties the draft	After: one undo removes only " ok"

Not checked: undo history across a rich text flip. The flip remounts the editor, which starts a new history, the same on main.

The Tiptap composer used ProseMirror's history defaults: a 500ms group delay with adjacency grouping, so typing, deleting and pasting in one burst undid together. Lexical's history started a new step when the kind of change switched, with a one-second delay. A dispatch middleware now closes the history group on a switch between inserting, deleting and anything else, and the composer's own paste handler tags its transactions as pastes so a paste is one step.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This is a focused, well-tested fix to composer undo grouping, but it also changes the default undo delay and grouping behavior for every composer user. That product-wide behavior change warrants human review.

Notes:

Diff unchanged. Approvability was decided on eligibility alone.

📝 Walkthrough

Walkthrough

The composer now classifies document transactions to group undo history by change kind. The editor uses a 1000 ms grouping delay and marks paste and cut transactions. Tests cover typing, deletion, paste, cut, store rewrites, composition, and pauses.

Changes

Composer undo grouping

Layer / File(s)	Summary
Classify and group transactions `apps/web/src/composer-undo-grouping.ts`	Adds transaction classification for insertions, deletions, and other changes. The grouping helper closes history groups when change kinds differ or the new change is classified as other.
Editor integration and tests `apps/web/src/components/ComposerPromptEditorTiptap.tsx`, `apps/web/src/composer-undo-grouping.test.ts`	Registers the grouping extension and configures a 1000 ms history delay. Paste and cut transactions are marked. Tests cover grouping across change kinds, composition, store rewrites, and pauses.

🟡 Minor · Tag the custom cut transaction as uiEvent: "cut". · ComposerPromptEditorTiptap.tsx:1349

apps/web/src/components/ComposerPromptEditorTiptap.tsx:1349
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Tag the custom cut transaction as uiEvent: "cut".

handleCopyCut prevents the native cut at Line 1342. Tiptap’s deleteSelection() does not add clipboard metadata. (raw.githubusercontent.com)

The new classifier therefore treats this cut as "delete", not "other". If a user backspaces, cuts adjacent text, and backspaces again within one second, the operations remain one undo step. One undo restores the surrounding deletions as well as the cut. (raw.githubusercontent.com)

Set the metadata on the same chained transaction before deleteSelection().

The composer's cut handler deletes the selection itself, so ProseMirror never tags it as a cut and it merged with deletions around it. It now tags the transaction the same way the paste handler does.

Merges origin/main (6c8fed3) into t3code/codex-turn-mapping (3eaae44). The previous sync (pingdotgg#14668) was squash-merged, so V2 already holds main's content up to a3abb52 without the merge parent. This merge was built with `git merge-tree --merge-base=a3abb52660`, so only the 15 commits in a3abb52..6c8fed3 apply and nothing already synced re-conflicts. No new migrations on main. Brings in pingdotgg#14673 (batched GitHub GraphQL polling), pingdotgg#13926 (beta Working section), pingdotgg#14678 (update providers on every machine), pingdotgg#14674, pingdotgg#13426, pingdotgg#14700, pingdotgg#14675, pingdotgg#14601, pingdotgg#14532, pingdotgg#14756, pingdotgg#14734 (Expo 58 update), the 1.4.0 mobile version bump, pingdotgg#12615, pingdotgg#14367 and pingdotgg#14710. V1 files V2 deleted (kept deleted): - orchestration/PullRequestSyncReactor(.test).ts and orchestration/ThreadPullRequestReactor.ts: pingdotgg#14673's reactor batching. Git matched them to V2's orchestration-v2/PullRequestSyncReactor(.test).ts and ThreadPullRequestService.ts, so the change landed there: one queued "requested" sweep reads a burst of requestSync keys together, a summary that places a PR in no stack skips the stack read, and a stack-number change in the summary triggers a stack refresh. Main's two new reactor tests merged into V2's test file and use V2's harness as-is. - web ChatMarkdown.workspace-images.test.tsx: V2 removed it in 894f6c4. pingdotgg#12615 added Windows-path cases there; the link case is ported into V2's ChatMarkdown.test.tsx "Windows file links" block. The image-resource cases depend on that file's asset mocks and are not ported. Content conflicts: - orchestration-v2/PullRequestSyncReactor.ts: main's sweep(scope) signature over V2's projections.getThreadsWithPullRequests() read. - orchestration-v2/ThreadPullRequestService.ts: main's concurrency 32 (was V2's 25), so a sweep's branch lookups reach GitHubCli's 50-wide GraphQL document together. - chat/ChatHeader.tsx: kept V2's slim header (f71e6a2); main's header-actions block is not in V2. pingdotgg#13426's ChatView half (the maximize control leaves the flex flow when closed) is applied to V2's panel controls in ChatView.tsx. - Sidebar.logic(.test).ts, Sidebar.tsx: pingdotgg#13926 on V2's sidebar model. isSidebarThreadWorking folds V2's "working" and "waiting" (idle with open background tasks, main's "monitoring") statuses, minus a ready plan. sortInboxThreadsByReturn reads latestRun instead of latestTurn. V2's subagent filter, section resolver and CollapsibleSectionHeader stay; the Working header uses the muted tone. Main's status tests are rewritten on V2's runtime fixture. - settings/SettingsPanels.tsx, settingsSearch.ts, docs/user/thread-sidebar.md: both sides (V2's limited-thread rows and title docs, main's Working section row and docs). pingdotgg#14678 uses the existing server.updateProvider RPC, which V2's ws.ts serves through providerMaintenanceRunner, so no server change is needed.

Merges upstream `pingdotgg/t3code` up to `024d49520`: 12 commits from base `20012ebd8`. **This deliberately stops short of `upstream/main` (`4f7760e6a`).** ## Why it stops at `024d49520` The next upstream commit, `de3439142` (pingdotgg#2829 "introduce new orchestrator", 1,907 files), deletes `packages/contracts/src/orchestration.ts` and client-runtime `threadReducer.ts` and replaces them with `orchestrationV2.ts`. The `orchestration.*` RPC method names stay the same, but every command, event, shell and thread payload is a new schema. `crates/t3code` on Moatless `main` has no V2 support, so merging it would ship a client that cannot decode anything the backend sends. It would also remove the anchors for five fork deltas: Message Origin, Thread Fork, Thread Visibility, Thread Follow and Thread Owner Name. `docs/fork/gaps.md` now has an entry for this, with what closes it and what to re-point. **Merging past it needs a person to decide: V2 support in the backend, or a client adapter.** Until that happens, every later upstream commit waits behind it, the web-only fixes included. ## Merge - Conflicts: none. Landed 41 files against 41 in the upstream range (exact match); fork delta 756 files. - `pnpm-lock.yaml` re-derived with `install.mjs`; the fork's edges are present. - `verify.mjs` (full run): all 10 checks passed (duplicate-adds, tripwires, resolution-check, unsupported-methods, lockfile, fmt, lint, typecheck, build, test). - Unsupported methods: no ADD, no DROP. ## Feature classification **Usable as-is** - Composer undo groups the way the Lexical composer did (pingdotgg#14674, `composer-undo-grouping.ts`) - Markdown keeps Windows paths intact in link and image destinations (pingdotgg#12615, `ChatMarkdown.tsx`; the mermaid delta still applies) - Desktop dark-mode markdown pages no longer render invisible (pingdotgg#14601) - Mobile: Expo 58 update, the Android thread crash fix, project picker fixes, version bumps (pingdotgg#14734, pingdotgg#14850, pingdotgg#14532, pingdotgg#14756) - Removed unused cloud/terminal debug flags (pingdotgg#14367); release v0.0.45; triage skill docs (pingdotgg#14852) **Unsupported in Moatless / needs implementation** - None in the merged range. Orchestrator V2 (`de3439142`) is outside it; see above. **Backend behavior to consider reproducing in Moatless** - pingdotgg#13295 `apps/server/src/orchestration/Layers/OrchestrationEngine.ts`: when reconciling, republish only the events this dispatch itself appended. Otherwise a second server sharing a state directory restarts provider turns another server already handled. Added to the gaps register's "Runtime fixes" entry. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --- Moatless task: https://moatless.soaplabstest.com/tasks/851793e2-b605-4dee-9710-0788efe45f5d

fix(web): give a composer cut its own undo step

880acdc

The composer's cut handler deletes the selection itself, so ProseMirror never tags it as a cut and it merged with deletions around it. It now tags the transaction the same way the paste handler does.
