Mr.Docs

Full-fidelity C++ documentation, straight from your code.

Get started Download

Keep the code simple. Get clear documentation.

Mr.Docs understands modern C++. You focus on design and maintainability.

Single Source of Truth

Mr.Docs turns the documentation comments that live next to your C++ declarations into authoritative reference pages. One source of truth—your code.

Built for C++

Mr.Docs models C++ accurately: overload sets, concepts and constraints, deduced return types, aliases, constants, SFINAE, inherited and hidden members, niebloids, and more.

Multiple output formats

Export to AsciiDoc, HTML, or XML - or extend it with your own generator plugins.

Customizable

Highly configurable: control output format and theme, tailor symbol selection, and tune generation to match your project’s standards.

More Code, Fewer Workarounds

Mr.Docs lets you keep code simple and maintainable.

  • Accurate rendering of attributes and exception specifications (e.g. [[noreturn]], noexcept).
/** Exit the program. The program will end immediately. @note This function does not return. */ [[noreturn]] void terminate() noexcept;

terminate

Exit the program.

Synopsis

Declared in <terminate.cpp>
[[noreturn]] void terminate() noexcept;

Description

The program will end immediately.

NOTE

This function does not return.

  • Documentation comments become structured reference pages—synopsis, description, parameters, and returns.
/** Return the distance between two points This function returns the distance between two points according to the Euclidean distance formula. @param x0 The x-coordinate of the first point @param y0 The y-coordinate of the first point @param x1 The x-coordinate of the second point @param y1 The y-coordinate of the second point @return The distance between the two points */ double distance(double x0, double y0, double x1, double y1);

distance

Return the distance between two points

Synopsis

Declared in <distance.cpp>
double distance( double x0, double y0, double x1, double y1);

Description

This function returns the distance between two points according to the Euclidean distance formula.

Return Value

The distance between the two points

Parameters

Name Description
x0 The x-coordinate of the first point
y0 The y-coordinate of the first point
x1 The x-coordinate of the second point
y1 The y-coordinate of the second point
  • Use directives to capture semantics beyond the signature.
/** Return true if a number is prime. @par Complexity Linear in n. @return Whether `n` is prime. @param n The number to test */ bool is_prime(unsigned long long n) noexcept;

is_prime

Return true if a number is prime.

Synopsis

Declared in <is_prime.cpp>
bool is_prime(unsigned long long n) noexcept;

Complexity

Linear in n.

Return Value

Whether n is prime.

Parameters

Name Description
n The number to test
