highlighter
The code highlighter: a light and a dark theme, as CSS variables, so the colours follow the system like the rest of the page.
import { highlighters, LANGS } from "#codebase/tcmts/site"; import type { Highlighter } from "#codebase/tcmts/site"; import { createHighlighter } from "shiki"; export function highlighter(): Promise<Highlighter> { let h = highlighters.get("site"); if (!h) highlighters.set("site", (h = createHighlighter({ themes: ["github-light", "github-dark"], langs: LANGS }))); return h; }
