example.rst

Here is a video I like:

Neat, huh?

youtube.py

from docutils import nodes
from docutils.parsers.rst import Directive


class youtube(nodes.General, nodes.Element):
    pass


def html_visit_youtube(self, node):
    self.body.append(f'<iframe width="560" height="315" src="https://www.youtube-nocookie.com/embed/{node["video_id"]}" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>')
    raise nodes.SkipNode()


class YoutubeDirective(Directive):
    required_arguments = 1

    def run(self):
        video_id, = self.arguments
        return[youtube('', video_id=video_id)]


def setup(app):
    app.add_node(youtube, html=(html_visit_youtube, None))
    app.add_directive("youtube", YoutubeDirective)

    return {
        "version": "0.1",
        "parallel_read_safe": True,
        "parallel_write_safe": True,
    }
