Overview

Parses inline MediaWiki markup within a line of text. Handles bold (”‘), italic (”), links ([[…]]), external links ([…]), and HTML inline tags via an InlineTagRegistry.

Examples:

With custom registry

registry = InlineTagRegistry.build_from_default do |r|
  r.register("mark", :formatting, AST::Bold)
end
parser = InlineParser.new(handlers: registry)

def initialize(handlers: nil, depth: 0, unknown_tags: nil)
  @registry = handlers || InlineTagRegistry.default
  @depth = depth
  @unknown_tags = unknown_tags || Hash.new(0)
end

Instance Attribute Details

#unknown_tags ⇒ Hash{String => Integer} (readonly)

Returns tag-name → occurrence count for HTML-like inline tags whose names are not registered. Shared with nested InlineParser instances so depth-recursive parses contribute to the same tally.

Returns:

  • (Hash{String => Integer}) —

    tag-name → occurrence count for HTML-like inline tags whose names are not registered. Shared with nested InlineParser instances so depth-recursive parses contribute to the same tally.
