Table of Contents

Auto-generated table of contents for Flarum posts. Builds anchors from Markdown headings (#, ##, ###) and renders an inline TOC at the top of each post that has two or more headings.

Works in two places out of the box:

• Forum discussion posts (anywhere a .Post-body is rendered)
• Link Robins Blog articles (.LinkRobinsBlog-post-body)

What it does

For every heading in a post, the extension:

• Generates a stable, slugified id from the heading text
• Inserts an invisible scroll anchor above the heading, so clicking a TOC link lands the heading at a comfortable position rather than pinned to the viewport top
• Adds a click-to-copy affordance on the heading itself — clicking copies a deep link to the section

For each post with two or more headings, the extension prepends a compact "Contents" card listing every heading as a navigable link, indented by heading depth.

What it does NOT do

• No BBCode for arbitrary anchors. Headings are anchors. If you want a heading-less anchor, add a heading.
• No floating bottom-right overlay TOC. The inline-at-top-of-post TOC covers the same UX with much less DOM fragility.
• No post-stream scroll synchronization or progress bars.

Configuration

Two settings, both with sensible defaults:

These currently have no admin UI — set them via the Flarum settings API or directly in the settings table. An admin panel can be added later if needed.

How heading ids are generated

Within a single post, ids are stable and predictable:

• Heading text is lowercased, non-alphanumeric characters become dashes, repeating dashes collapse
• Empty headings get a section fallback
• Collisions inside the same post get -2, -3, suffixes
• Discussion posts prefix the id with the post number (e.g. 3-introduction) so two posts on the same page don't fight over #introduction

The result is that linking to a section is just <post URL>#<id>. Hovering a heading shows a small link icon; clicking copies the URL.
