Post Numbers

Adds a #1, #2, #3... number to each post in a discussion. Helpful for referring to specific posts ("see #4 above") and giving readers a sense of where they are in a long thread.

Ported to Flarum 2.0 from ziven/flarum-post-number (MIT).

What it does

Extends CommentPost.headerItems to append a small #N label to each post's header, where N is the post's sequence number within its discussion. Hidden posts are skipped, matching the original extension's behavior.

Requirements

• Flarum 2.0 or later
• PHP 8.3 or later

What changed from the 1.x original

The original extension targeted Flarum 1.x and relied on a webpack/JSX build pipeline. This 2.0 port:

• Targets flarum/core ^2.0
• Uses the runtime extend() helper from the export registry with string-path lazy module resolution, so no JSX/build step is required
• Uses the canonical 2.0 model accessors (post.number(), post.isHidden()) with fallback to raw attribute access for resilience
• Renames the CSS class to LinkRobinsPostNum to avoid colliding with the original if both are ever installed side-by-side
• Adds tabular-numeric digit alignment so post numbers stay column-aligned in lists

Translation strings follow the same shape — the only difference is the namespace key.
