Link Markdown copies to Markdown copies

How to do it

An agent that follows a link from a Markdown page to an HTML page pays for the whole layout. Rewrite internal links when you build the Markdown, including breadcrumbs, chapter links and previous and next links. Leave links to other sites alone. The copies themselves follow Offer every page as Markdown.

Examples

JavaScript example

export const toMarkdownLinks = (markdown, host) =>
  markdown.replace(/\]\((https:\/\/[^)\s]+)\)/g, (link, url) => {
    const { hostname, pathname } = new URL(url);
    return hostname === host && !/\.\w+$/.test(pathname) ? `](${url.replace(/\/?$/, '')}.md)` : link;
  });

Python example

import re
from urllib.parse import urlsplit

def to_markdown_links(markdown: str, host: str) -> str:
    def rewrite(match: re.Match) -> str:
        url = match.group(1)
        parts = urlsplit(url)
        if parts.hostname == host and not re.search(r"\.\w+$", parts.path):
            return f"]({url.rstrip('/')}.md)"
        return match.group(0)
    return re.sub(r"\]\((https://[^)\s]+)\)", rewrite, markdown)

How to check

A script reads every .md page. It fails on any link to your own host whose path does not end in .md, apart from images and feeds.
