#linkify(link, *args) ⇒ Object

Note:

Appendix links will be resolved only within the namespace they’re defined in (class or module).

Handles reference links to Appendix objects in @see tags by printing out their readable titles in the anchor text and tooltip.

Delegates to YARD::Templates::Helpers::HtmlHelper#linkify if the @see tag syntax does not qualify as an appendix one.

Note that the syntax expected is ‘@see Appendix: APPENDIX_NAME` where only the `APPENDIX_NAME` is variable.

Examples:

Referencing appendix objects:


# Some method description.
# ...
# @see Appendix: Bananas
def some_method()
end
