`--embed-mixins` (https://github.com/ruby/rdoc/pull/842) * Embed mixed-in methods and constants with `--embed-mixins` When `--embed-mixins` option is set: - methods from an `extend`ed module are documented as singleton methods - attrs from an `extend`ed module are documented as class attributes - methods from an `include`ed module are documented as instance methods - attrs from an `include`ed module are documented as instance attributes - constants from an `include`ed module are documented Sections are created when needed, and Darkfish's template annotates each of these mixed-in CodeObjects. We also respect the mixin methods' visibility. This feature is inspired by Yard's option of the same name. * Add comment to document why we set object visibility Co-authored-by: Stan Lo <[email protected]> * Add the mixin_from attribute to CodeObject's initializer * Add test coverage for private mixed-in attributes. --------- https://github.com/ruby/rdoc/commit/481c2ce660 Co-authored-by: Stan Lo <[email protected]>
