The C++ documentation problem

C++ projects often have world-class performance and terrible documentation. Doxygen exists but produces output that looks like it was designed in 1999. Writing a modern README plus API reference is a multi-day project most teams skip.

Frequently asked questions about C++ documentation

Does it work with CMake, Meson, and Bazel build systems?

Yes. Codec8 reads CMakeLists.txt, meson.build, and BUILD/WORKSPACE files to determine project structure and generate appropriate build and integration instructions.

Can it document header-only libraries?

Header-only libraries are ideal for Codec8 — all the public API is in the headers with no implementation to separate. It generates complete API reference from your .hpp files.

How does it handle C++17/20/23 features like concepts and modules?

Codec8 recognizes C++20 concepts and requires clauses and documents them in a way that makes the constraints clear to users, rather than showing raw template metaprogramming.
