@amanda-mitchell/remark-footer

There is a current proposal for a CommonMark extension for a footer element here: https://talk.commonmark.org/t/syntax-for-footer/2070

This package implements that proposal as a remark-parse plugin.

Installation

yarn add @amanda-mitchell/remark-footer

Use

Construct a unified parser and pass footers to it as a plugin:

import vfile from 'to-vfile';
import report from 'vfile-reporter';
import { unified } from 'unified';
import parse from 'remark-parse';
import { footers } from '@amanda-mitchell/remark-footer';
import remark2rehype from 'remark-rehype';
import stringify from 'rehype-stringify';

const document = `^^ a footer`;

unified()
  .use(parse)
  .use(footers)
  .use(remark2rehype)
  .use(stringify)
  .process(vfile.readSync('example.md'), function (err, file) {
    console.error(report(err || file));
    console.log(String(file));
  });

When run, this script will print

<footer><p>A footer</p></footer>

Implementation notes

Many remark-parse plugins also provide behavior to serialize an mdast syntax tree back to markdown. This plugin does not support this, but again, I'd be happy to accept a PR that adds the feature!
