Module: Coradoc::AsciiDoc::Transform::AttributeListToMetadata

Defined in:
lib/coradoc/asciidoc/transform/attribute_list_to_metadata.rb

Overview

Single source of truth for AsciiDoc Model::AttributeList -> CoreModel::Metadata conversion (DRY/MECE).

Promotes the first positional attribute to ‘style` and the `role=` named attribute to `role`, matching the AsciiDoc block-header semantics that downstream consumers (coradoc-mirror) dispatch on to pick a JS section type (annex, abstract, …).

Returns nil for anything that isn’t a typed AttributeList so callers can pass through optional/missing inputs without an extra guard.
