class Refinement - Documentation for Ruby 3.5

Refinement is a class of the self (current context) inside refine statement. It allows to import methods from other modules, see import_methods.

static VALUE
refinement_import_methods(int argc, VALUE *argv, VALUE refinement)
{
}

Imports methods from modules. Unlike Module#include, Refinement#import_methods copies methods and adds them into the refinement, so the refinement is activated in the imported methods.

Note that due to method copying, only methods defined in Ruby code can be imported.

module StrUtils
  def indent(level)
    ' ' * level + self
  end
end

module M
  refine String do
    import_methods StrUtils
  end
end

using M
"foo".indent(3)


module M
  refine String do
    import_methods Enumerable
    
  end
end

Also aliased as: import_methods

VALUE
rb_refinement_module_get_refined_class(VALUE module)
{
    ID id_refined_class;

    CONST_ID(id_refined_class, "__refined_class__");
    return rb_attr_get(module, id_refined_class);
}

Return the class or module refined by the receiver.

module M
  refine String do
  end
end
