cmaas/markdown-it-table-of-contents

This is a plugin for the markdown-it library that generates a table of contents from Markdown headings. It scans documents for heading tags and creates a nested list of links, inserting the TOC where `[[toc]]` is placed in the Markdown source. The plugin is designed for developers using markdown-it who want to automatically generate navigable tables of contents in their rendered HTML, with extensive customization options for formatting, styling, and link generation.
