Overview

Extracts RBS type alias definitions from generated .rbs files.

Reads type aliases from RBS files (typically in sig/generated/) which have already been properly parsed by RBS::Inline. This is more reliable than re-parsing @rbs! blocks ourselves.

RBS format is straightforward:

module Namespace
  # Description comment
  type name = definition
end

Examples:

loader = RbsTypeAliasLoader.new(true, logger, rbs_dir: "sig/generated")
type_aliases = loader.load
# => { "Archema" => [{ name: "attribute_value", definition: "...", ... }] }
