plgg-highlight

Syntax highlighting with zero new dependencies, built from scratch on plgg. It plugs into plgg-md's Highlighter seam and drives the already-present typescript compiler's ts.createScanner to tokenize TS / TSX / JS / JSX / JSON into classified plgg-view Html<never> spans — with an escaped <pre><code> fallback for everything else.

Why it exists

plgg-md renders code fences through a Highlighter seam but stays language-agnostic itself. plgg-highlight fills that seam for the TypeScript family by reusing the compiler the monorepo already ships — no highlight.js, no shiki, no new dependency:

plgg ── plgg-md ── plgg-highlight
          (Highlighter seam)  └── typescript scanner

How it's organized

• Lang — alias-normalizes a fence language (ts, tsx, js, jsx, json) to the scanner's mode; an unknown language selects the fallback.
• Token — drives ts.createScanner to walk the source into classified tokens.
• Render — folds those tokens into plgg-view Html<never> spans, degrading to an escaped <pre><code> block when no language matches.

The output is a plgg-view tree, so highlighted code composes into a page the same way any other view does. The exact token classes and the class names live in the plgg-highlight source.
