libCat is a non-POSIX compliant C++26 runtime. It has no pthreads nor =malloc()=, and by extension no exceptions. It has type-safe arithmetic, SIMD, fast syscalls, CRTP interfaces, hierarchical memory allocators, and value-based error handling, among many other features.

More essays and videos will come in the future.

• Building libCat requires a recent development version of GCC 15 or Clang 20 from the =trunk= branch. Compiling libCat is only routinely tested using =ninja=. Configuring the build requires CMake 3.29.

  +BEGIN_SRC

  $ cmake -B build/ -G 'Ninja Multi-Config' # or: cmake -B build -GNinja $ cmake --build build/ # or: ninja -C build/ $ ./build/tests/Debug/unit_tests

  +END_SRC

The =.clang-format= and =.clang-tidy= configurations are only compatible with recent builds of clang-tools from the =main= branch.
