In Ruby language, developers need to use both "include" and "extend" to implement mix-in having instance methods and class methods. The auto extending module is a well-known technique to realize it (ex.
ActiveSupport::Concern
, "extend" call inincluded
block, and so on).This supports the auto extending modules via modules having "autoextend:..." annotation. The
RBS::DefinitionBuilder
searches the extended modules from the annotations of the included modules.This is yet another version of #1503. This modifies
RBS::DefinitionBuilder::AncestorBuilder#one_singleton_ancestors
to get auto-extending modules.
