    Tokenizer & Hooks

    marked extensibility via tokenizer and hooks (from marked).

    Custom tokenizer — e.g. LaTeX via $...$

    import { Tokenizer, type Tokens } from "marked";
import Markdown, { Renderer } from "react-native-marked";

class CustomTokenizer extends Tokenizer {
  codespan(src: string): Tokens.Codespan | undefined {
    const match = src.match(/^\$+([^\$\n]+?)\$+/);
    if (match?.[1]) {
      return { type: "codespan", raw: match[0], text: match[1].trim() };
    }
    return super.codespan(src);
  }
}

const tokenizer = new CustomTokenizer();
const renderer = new Renderer();

export default () => (
  <Markdown value={"$ latex code $\n\n` other code `"} tokenizer={tokenizer} renderer={renderer} />
);

    Also see src/lib/types.ts:24 (tokenizer?: Tokenizer) and src/index.ts:3 exports MarkedTokenizer, MarkedHooks, MarkedLexer.

    Hooks

    Pass hooks to Markdown / useMarkdown. They run during parsing to transform tokens — e.g., sanitize, rewrite links, inject custom tokens.

    import { MarkedHooks } from "react-native-marked";
const hooks = new MarkedHooks({ /* override */ });
<Markdown value={md} hooks={hooks} />
