fix(web): preserve Mermaid source when copying selected text by NikitaMGrimm · Pull Request #16249 · pingdotgg/t3code

NikitaMGrimm · 2026-10-05T23:13:20Z

Selecting a rendered Mermaid diagram currently drops its source from copied messages. This change preserves fenced Mermaid Markdown in plaintext and visible HTML, together with only the selected surrounding prose. Selecting inside a diagram copies the full source; Show code keeps ordinary partial selection.

The implementation reuses the existing copy override and code-block serializer. Search-only source stays out of clipboard output, and links in Mermaid comments cannot export an unselected context record. Selecting the actual context chip still includes that record.

Maintainer takeover of #16249, crediting @NikitaMGrimm for the original implementation and context-boundary fix. Contributor commits are retained; main was merged normally.

Verification

Replaced eight added cases across two files with six meaningful cases in the existing rendered timeline suite. Removed the one-off synthetic-DOM suite.
174 focused tests pass across clipboard, timeline, renderer and thread-find suites. Targeted lint/format and web typecheck pass.
Parallel full-diff review round two: both reviewers found no actionable issues. Round one exposed and fixed duplicate source during thread search and missing visible HTML source.
Integrated headless Linux client: native Control+C and composer paste preserve the Mermaid code block; actual rendered copy handlers preserve partial surrounding prose, complete source from an inside selection, and partial Show code text. Active thread search produces one source block in plaintext and visible HTML. Context inclusion/exclusion is verified by rendered browser tests.

Evidence

After: rendered assistant diagram copied and pasted into the composer, preserving source.

After: native copy and paste recording

Before: the same rendered diagram and selection at the actual base only paste surrounding prose. The source is lost. Both captures use the same isolated thread and 1280×800 viewport.

Before: native copy and paste recording

Remaining gates and limits

Human approval for the clipboard context-export boundary remains required. Published-head build, lint, tests and correctness checks pass. Macroscope’s approvability result is neutral because human approval remains required. Packaged Electron, macOS, Windows, native iOS/Android, relay and tunnel modes were not exercised. Existing serializer whitespace normalization inside longer fences containing backticks remains unchanged; this does not claim byte-perfect source preservation for that case.

Implementation: gpt-6.1-sol via Codex in T3 Code. Tests: gpt-6-astra via Codex. Independent reviews: claude-opus-5-5 via Claude Agent and gpt-6-sol via Codex.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The change is a focused Mermaid clipboard fix with targeted browser coverage, preserving fenced source while keeping ordinary selections intact. It also changes the structured context-record clipboard boundary, which can carry attachment and workspace context and merits human review.

📝 Walkthrough

Rendered Mermaid diagrams now store their source as fenced Markdown. Clipboard handling uses that source for selections within diagrams. Context-record collection excludes Mermaid elements.

Changes: Mermaid Clipboard

Layer / File(s)	Summary
Markdown code-block serialization `apps/web/src/markdown-clipboard.ts`, `apps/web/src/markdown-clipboard.mermaid.test.ts`	An exported helper serializes source as a fenced Markdown code block. The existing code-block serializer delegates to it. Tests cover fence length when the source contains backticks.
Diagram clipboard payload `apps/web/src/components/chat/MermaidDiagram.tsx`, `apps/web/src/markdown-clipboard.ts`, `apps/web/src/components/chat/MessagesTimeline.tsx`, `apps/web/src/markdown-clipboard.mermaid.test.ts`, `apps/web/src/components/chat/MessagesTimeline.browser.test.tsx`	Rendered diagrams store their serialized source. Clipboard handling uses it for selections within a diagram and retains sanitized selected HTML. Context-record collection skips Mermaid elements. Tests cover diagram and source-view selections, and copying with or without a context chip.

observed — apps/web (ui) was modified; 5 changed files map to changed impact.

Before / after behavior

observed — Modified behavior in apps/web/src/markdown-clipboard.mermaid.test.ts: Adds jsdom test setup that clears the browser selection and document body after each test.
observed — Modified behavior in apps/web/src/markdown-clipboard.mermaid.test.ts: Adds parameterized expectations for selections across or partly inside a rendered Mermaid diagram: the clipboard payload includes the diagram’s stored Markdown source and includes surrounding text only for the selected portions.
observed — Modified behavior in apps/web/src/markdown-clipboard.mermaid.test.ts: Adds an expectation that Mermaid Markdown serialization uses a four-backtick fence when the source contains a run of three backticks.
observed — Modified behavior in apps/web/src/markdown-clipboard.mermaid.test.ts: Adds an expectation that selecting part of Mermaid source-view code produces only the selected text in the clipboard payload.

Explanation

The description covers the problem, implementation, scope context, verification results, UI evidence, limitations, and agent models and harnesses. The scope section does not explicitly quote or link a maintainer approval comment, but the maintainer takeover and linked PR provide relevant context. The description is otherwise complete and focused.

🤖 gpt-6.1-sol responding on behalf of NikitaMGrimm

Verified the structured-context concern and fixed it in 7c7a2d1. The user-message copy handler now excludes Mermaid source overrides when choosing context records; the source still copies as fenced Markdown. The regression failed before the fix and now confirms that an image link hidden in a Mermaid comment exports no image record unless its chip is selected. All 115 tests across the timeline and clipboard suites, web typecheck, and targeted lint/format checks passed (existing lint warnings only).

Hi! We are cleaning up open PRs, and this one does not say which model or harness was used to create it. If this change is really important, we recommend rebuilding the PR with a newer model and noting the model and harness in the PR description.

Select the rendered timeline message in this regression test.

The test creates the Mermaid diagram and context chip in a separate selected element, then dispatches copy on a paragraph from timeline. The assertions can therefore pass even if the rendered MermaidDiagram stops providing data-markdown-copy. Render the Mermaid source and chip through the timeline, then build the range from those rendered elements. This is a test-coverage improvement, not a current production defect.

Note

🤖 Claude Opus 5.5 responding on behalf of NikitaMGrimm

@coderabbitai Thanks, fixed in da4b580. The copy test now renders the Mermaid fence and the image chip through MessagesTimeline, waits for the real diagram, and selects the rendered elements. Both cases fail against main's MessagesTimeline.tsx, markdown-clipboard.ts and MermaidDiagram.tsx, and the browser file passes (66 tests, three runs).

@NikitaMGrimm Thanks for the fix. I checked da4b580bbd. The test now uses the rendered MessagesTimeline diagram and context chip, waits for the diagram SVG, and selects the rendered elements before dispatching the copy event. This addresses the test-coverage concern.

I did not rerun the tests.

Taking over this one as maintainer for batch web-misc-05. I will keep Mermaid selection copying focused, preserve the context-record boundary, and push the rebuilt and verified change here without merging.

# Conflicts: # apps/web/src/components/chat/MermaidDiagram.tsx # apps/web/src/markdown-clipboard.ts

…gg#16249) Co-authored-by: Julius Marminge <[email protected]> (cherry picked from commit dd5876e) Backport: drops the browser test; v0.1.0 has no browser test project.

Mermaid diagrams now render with pele instead of the mermaid package. Pele loads one small chunk per diagram type and takes its colors from the app theme, so a theme change needs no new render. Math labels use KaTeX. Copying selected text from a diagram keeps the Mermaid source (upstream pingdotgg#16249, same files). Dependencies: pele ^1.8.0 and katex ^0.16.47 added, mermaid removed. Upstream: pingdotgg/t3code fcb20e4 (pingdotgg#21472) and dd5876e (pingdotgg#16249). The Mermaid browser test is not carried over. Release-Note: Render Mermaid diagrams faster and in the app theme colors
