Add Schemd to a Markdown pipeline

01 / AdapterKeep the compiler boundary small

Schemd is parser-free, and a good adapter keeps it that way. It has exactly two responsibilities — recognize the fence, compile it — and everything past those two lines is someone else's problem, which is how it should be.

import { compileSchematic, parseSchematicFence } from '@schemd/core';

export function renderSchemdFence(body: string, info: string) {
	const fence = parseSchematicFence(info);
	return fence ? compileSchematic(body, fence).svg : undefined;
}

Recognize only the schemd language and hand every other fence straight back to the host parser. Emit the compiled SVG as trusted HTML on the server — and, as everywhere in this documentation, keep arbitrary HTML off that path.
