Simple code, simple documentation
MrDocs understands C++ so you can focus on keeping the code simple.
Single Source of Truth
Mr. Docs takes a specially formatted comment, called a Javadoc, which precedes a C++ declaration and renders it to form a reference as part of documentation.
It understands C++
Mr. Docs understands C++: Overload sets, private APIs, Concepts and constraints, unspecified return types, aliases, constants, SFINAE, hidden base classes, niebloids, and coroutines.
Multiple output formats
Choose from multiple output formats: Asciidoc, HTML, or XML.
Customizable
Mr. Docs is highly customizable. You can change the output format, the theme, and even the way the documentation is generated.
