marked-terminal

Custom Renderer for marked

allowing for printing Markdown to the Terminal. Supports pretty tables, syntax

highlighting for javascript, and overriding all colors and styles.

Could for instance be used to print usage information.

npm install marked marked-terminal

import { marked } from 'marked';
import { markedTerminal } from 'marked-terminal';
marked.use(markedTerminal([options][, highlightOptions]));
marked.parse('# Hello \n This is markdown printed in the terminal');

const marked = require('marked');
const TerminalRenderer = require('marked-terminal');
marked.setOptions({
  // Define custom renderer
  renderer: new TerminalRenderer()
});
// Show the parsed data
console.log(
  marked('# Hello \n This is markdown printed in the terminal')
);

Syntax Highlighting

Also have support for syntax highlighting using cli-highlight. You can override highlighting defaults by passing in settings as the second argument for TerminalRenderer.

Having the following markdown input:

var foo = function(bar) {
  console.log(bar);
};
foo('Hello');

...we will convert it into terminal format:

// Show the parsed data
console.log(marked(exampleSource));

This will produce the following:
