Informations about the package post-num
Link Robins 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.
What it counts
The number comes from Flarum's own per-discussion post number, not a count the extension keeps. That has two consequences worth knowing:
- Numbers are stable. A post keeps its number for the life of the discussion, so
#42in a quoted link still points at the same post later. - Numbers can have gaps. Deleting a post does not renumber the ones after it. A discussion that has had posts removed will skip numbers, which is correct — renumbering would break every existing deep link.
Hidden posts are skipped entirely: if a post is hidden, no number is rendered for it rather than a number for something you cannot read.
What it does NOT do
- No settings and no migrations.
- It does not renumber, or offer a "count only visible posts" mode — see the gap behaviour above.
- It does not add its own permalink or anchor. Flarum's post menu already has "Permalink", and the number sits next to it rather than duplicating it.
Styling
The number renders as a <span class="LinkRobinsPostNum"> in the post header, alongside the timestamp. Restyle it from your theme's custom LESS:
Requirements
- Flarum 2.0 or later
- PHP 8.3 or later
Installation
In Flarum admin → Extensions, find Link Robins Post Numbers and enable it. No configuration needed.
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
LinkRobinsPostNumto 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.
