About RDoc
RDoc is the standard documentation generation tool for the Ruby programming language. It parses Ruby source files and produces HTML or plain-text documentation from embedded comments written in a simple markup format. RDoc is included with the Ruby standard library and is the de facto tool for documenting Ruby gems and libraries.
Developers write documentation comments directly above classes, modules, and methods, and RDoc extracts and formats them into browsable reference docs. It supports cross-references, code examples, and attribute documentation. RDoc plays a foundational role in the Ruby ecosystem, ensuring that library authors can deliver consistent, readable API documentation alongside their code.
