Mp11, a C++11 metaprogramming library
Mp11 is a C++11 metaprogramming library based on template aliases and variadic templates. It implements the approach outlined in the article "Simple C++11 metaprogramming" and its sequel.
Mp11 is part of Boost, starting with release 1.66.0. It
however has no Boost dependencies and can be used standalone, as a Git submodule, for
instance. For CMake users, add_subdirectory is supported, as is installation and
find_package(boost_mp11).
Supported compilers
- g++ 4.8 or later
- clang++ 3.9 or later
- Visual Studio 2013 or later
Tested on Github Actions and Appveyor.
