Michael Ramos c08b188812 perf(ui): single Shiki highlighter, palette-matched code blocks, drop highlight.js (#1218)
* perf(build): stub out the dead Oniguruma WASM in every bundle

@pierre/diffs picks its Shiki engine with a runtime ternary:

    engine: preferredHighlighter === "shiki-wasm"
      ? createOnigurumaEngine(import("shiki/wasm"))
      : createJavaScriptRegexEngine()

Plannotator pins `preferredHighlighter: 'shiki-js'` (and Pierre's own
default is 'shiki-js'), so the Oniguruma branch never executes. Because
the choice is a runtime ternary, bundlers keep the `import("shiki/wasm")`
edge anyway and inline `@shikijs/engine-oniguruma/wasm-inlined`, a
~622 KB base64 blob, into the single-file HTML builds. The review app
paid for it twice: once on the main thread (via
`highlighter/shared_highlighter.js`) and once inside the `?worker&inline`
Pierre worker.

Alias `shiki/wasm` to a stub that throws if it is ever reached. Wired via
`resolve.alias` rather than a plugin because `resolve.alias` is shared
with Vite's worker build and `plugins` are not.

Highlighting output is unchanged: the JS regex engine was already the one
doing the work. Opting back into 'shiki-wasm' now fails loudly instead of
silently costing every user a megabyte of dead bytes.

    apps/review/dist/index.html  19,424,646 -> 18,180,545  (-1,244,101 raw / -463,348 gzip)
    apps/hook/dist/index.html    23,032,467 -> 22,410,416    (-622,051 raw / -233,485 gzip)

* perf(ui): consolidate code highlighting onto Shiki, drop highlight.js

The app shipped two highlighters. Shiki already tokenised the code-review
diff pane (via @pierre/diffs, JavaScript regex engine); highlight.js
separately coloured markdown fences and review suggestion snippets at
~982 KB minified for a full build of ~190 grammars. That second
highlighter is now gone.

Every call site moves onto `packages/ui/utils/codeHighlight.ts`, a thin
wrapper over Pierre's SHARED Shiki instance:

  CodeBlock, Viewer, PlanCleanDiffView   markdown fences
  InlineMarkdown                          code-file hover preview
  HighlightedCode                         review suggestion snippets

Reusing Pierre's instance rather than standing up a second fine-grained
one is deliberate. Pierre imports Shiki's full bundle, so every grammar
and theme is ALREADY inlined in the single-file builds: a separate
highlighter with a curated language list would have duplicated a subset
of bytes that are already there. Sharing costs nothing, gives every
language Shiki bundles instead of a shortlist, and — the point of the
change — guarantees fences resolve the exact same theme the diff pane
resolves.

Theming. `SHIKI_THEME_MAP` / `resolveSyntaxTheme` move from
`packages/review-editor/hooks/usePierreTheme.ts` to
`packages/ui/utils/syntaxTheme.ts`; usePierreTheme re-exports them, so
the review editor's imports are unchanged. `useFenceTheme()` feeds the
components and re-highlights on palette or mode change. Code blocks now
follow the active palette across all ~52 themes in both light and dark,
instead of always rendering github-dark and relying on hand-written
`.hljs-*` override stacks to stay legible. Those stacks are deleted:
`packages/editor/index.css`'s light-mode token palette, and
`colorblind.css`'s hand-tuned tokens which existed to APPROXIMATE
@pierre/theme's protanopia-deuteranopia themes that are now simply used.

Behaviour held fixed:

  - Language-less fences stay plain text (#1212). No auto-detection
    anywhere, including the hover preview, which previously called
    `hljs.highlightAuto`. `HighlightedCode` derives its language from
    the caller's file path; an unknown extension renders plain.
  - `applyHighlight(el, ...)` keeps the imperative `hljs.highlightElement`
    DOM contract the annotation layer reaches into, and writes plain text
    at final size first so async highlighting causes no layout shift.
    Already-attached grammars highlight synchronously — no flicker on
    cached highlights.
  - It also verifies the rendered text is byte-identical to the source
    and falls back to plain otherwise, because annotations address code
    blocks by text offset.
  - `@plannotator/ui`'s public API is unchanged: the highlighter is a
    module-level default like the package's other seams, no new props.

The `hljs` class on fenced `<code>` becomes `pn-code` (it is a
structural hook for blockTargeting, vim navigation and print.css, and it
named a library we no longer ship). `language-*` stays.

    apps/review/dist/index.html  18,180,545 -> 17,270,889  (-909,656 raw / -291,921 gzip)
    apps/hook/dist/index.html    22,410,416 -> 21,704,434  (-705,982 raw / -238,096 gzip)

Verified the diff pane is untouched: the rendered Pierre shadow-DOM
markup is byte-for-byte identical between an origin/main build and this
one (SHA-256 aa1ee88a…).

* fix(ui): strip stray NUL bytes from the code-highlight source

Two U+0000 bytes slipped into comments in the previous commit, which made
git treat the file as binary. Replaced with spaces; no behaviour change.

* fix(ui): keep code-block annotation marks across highlight swaps

Fenced code is annotated by hand: one `<mark data-bind-id>` inside the
`<code>` element, which `applyHighlight` also owns. Every highlight swap
(palette change, dark/light toggle, or the first async grammar attach
after load) replaces that element's children, so the mark was silently
wiped and nothing put it back. Annotation state, the sidebar panel and
exports were unaffected; the loss was purely visual, and deterministic.

`applyHighlight` now publishes every write through `onCodeHighlightSwap`,
synchronously, immediately after it. `Viewer` subscribes and re-paints the
fence's mark, so a swapped block ends up with BOTH the new theme's tokens
and its annotation. The shared painter (`paintCodeBlockMark`) moves the
token spans into the mark instead of flattening them to text, so creating
an annotation no longer costs a block its colours either.

Being driven by the swap also fixes the cousin race by ordering rather
than timing: share/draft restore runs on a timer after load, and on a slow
machine the first async swap could land after it and wipe the restored
marks per block. A restore that painted before the swap is now
re-established in the same task the swap ran in, and one that runs after
finds the mark already there.

Removal tombstones the id before re-highlighting, because the host drops
the annotation from state a tick later — without it the swap listener
would paint the just-removed annotation back in, and a fence carrying a
second annotation would end up bare.

Also closes the named gap in the WASM coverage: entry-assets only grepped
source, so a future @pierre/diffs bump could reintroduce the inlined blob
through a different import specifier unnoticed. It now greps the built
`apps/{review,hook}/dist/index.html` for the base64 WASM magic, skipping
on an unbuilt checkout and running for real in the CI job that builds the
bundles.

Tests

This directory contains manual testing scripts for Plannotator.

Manual Browser UI Smokes (tests/manual/local/)

These are local-only scripts for launching Plannotator UI flows with fixture data so you can manually verify them in a browser. They are not automated CI tests.

Plan review UI smoke tests:

./tests/manual/local/test-hook.sh          # Claude Code simulation
./tests/manual/local/test-hook-2.sh        # OpenCode origin badge test
./tests/manual/local/test-codex-plan-review-e2e.sh  # Real Codex Stop-hook flow in disposable HOME

Code review UI:

./tests/manual/local/test-opencode-review.sh  # Code review UI test
./tests/manual/local/test-worktree-review.sh  # Worktree support test (creates sandbox with 4 worktrees)

See UI-TESTING.md for detailed UI testing documentation.

The end-to-end, user-centered Vim controls matrix lives in manual/vim-ux-smoke.md. It covers real Markdown and raw-HTML navigation, selection, annotation, focus recovery, HUD behavior, and native-control compatibility.

Integration & Utility Tests (manual/local/)

These scripts test integrations, releases, and provide utilities.

Binary release testing:

./tests/manual/local/test-binary.sh        # Test installed binary from ~/.local/bin/

Tests the installed plannotator binary to verify releases work correctly.

Bulk plan testing (Obsidian integration):

./tests/manual/local/test-bulk-plans.sh    # Iterate through ~/.claude/plans/

Opens each .md file from ~/.claude/plans/ in Plannotator. Great for testing Obsidian integration with multiple plans.

OpenCode integration sandbox:

./tests/manual/local/sandbox-opencode.sh [--disable-sharing] [--keep] [--no-git]

Creates a temporary sandbox with a sample React/TypeScript project, initializes git with uncommitted changes, sets up the local OpenCode plugin, and launches OpenCode for full integration testing.

Options:

  • --disable-sharing: Creates opencode.json with sharing disabled
  • --keep: Don't clean up sandbox on exit
  • --no-git: Skip git initialization (tests non-git fallback)

Codex Stop-hook end-to-end harness:

./tests/manual/local/test-codex-plan-review-e2e.sh [--keep] [--skip-build]

Builds the hook and review apps, creates a disposable HOME plus sample git repo, copies your Codex auth.json, enables hooks, and runs a real codex exec against the sample project. The script writes logs, rollout paths, history indices, and session URLs into an artifact directory under the temp root.

Tips:

  • Set PLANNOTATOR_BROWSER=/usr/bin/true when you want to drive the opened plan-review session with Playwright instead of auto-opening a browser.
  • The validated workflow is: run the script in one terminal, then point Playwright at the printed session URL from a second terminal.

Obsidian utility:

./tests/manual/local/fix-vault-links.sh /path/to/vault/plannotator

Adds Obsidian backlinks ([[Plannotator Plans]]) to existing plan files in your vault.

SSH Remote Testing (manual/ssh/)

Tests SSH session detection and port forwarding for remote development scenarios.

cd tests/manual/ssh/
docker-compose up -d
./test-ssh.sh

See manual/ssh/DOCKER_SSH_TEST.md for detailed setup instructions.
