Module parser/rules/block/gallery

Block rule for the Wikidot [[gallery]] image gallery.

[[gallery size="thumbnail" order="name" viewer="no"]]
: first-image.jpg
: *page/other-image.jpg link="some-page" alt="Alt text"
[[/gallery]]
Copy

The content form requires the ]] to be followed immediately by one or more : source lines and a [[/gallery]] close tag (Wikidot regex \[\[gallery(\s[^\]]*?)?\]\](?:((?:\n: [^\n]+)+)\n\[\[/gallery\]\])?). Anything else falls back to the standalone content-less form, which shows the current page's image attachments after data resolution (content: { type: "auto", files: null }); the following text then parses normally.

Honored opening-tag attributes are size (small / medium / thumbnail / square / original, fallback thumbnail), viewer ("no"/"false" disable the lightbox) and order (auto-collection sort order, with Wikidot's deprecated aliases normalized).

Deliberate differences from the Wikidot parser: the opening tag must fit on one line and attribute names are lowercased with unquoted values accepted (both shared with wdpr's other block rules), and flickr: sources get no special treatment — they resolve like any other filename (wdpr does not call the Flickr API).
