(sigil publish generate)

Create a pipeline stage that generates a collection index page.

Filters items with the match predicate, sorts them, and creates a synthetic item that renders as a listing page.

(collection-page
  match: (has-tag? "post")
  title: "Blog"
  output: "/blog/index.html"
  sort-by: date:
  sort-order: 'descending)

Create a pipeline stage that adds a custom SXML page.

The content can be either:

• Direct SXML: a list like (div (h1 "Hello"))
• A function: (lambda (config state) sxml) for dynamic content

;; Static content
(sxml-page
  path: "/about"
  title: "About"
  content: `(div (h1 "About Us") (p "We build things.")))

;; Dynamic content with access to config/state
(sxml-page
  path: "/stats"
  title: "Site Stats"
  content: (lambda (config state)
             `(div (p "Total pages: " ,(length (state-items state))))))

Create a predicate that checks if item has a specific tag.

(filter (has-tag? "published") items)

Create a predicate that checks if item has a metadata key.

(filter (has-metadata? nav-group:) items)

Create a predicate that checks if item path matches a pattern.

(filter (matches-path? "/posts/") items)
