"{fmt} is an open-source formatting library for C++. It can be used as a safe and fast alternative to (s)printf and iostreams."
See {fmt} documentation for usage and details.
Note: This is the source code for the build2 package of the {fmt} C++ library,
the actual library sources snapshot can be found in the ./upstream/ submodule.
Configuration Options:
config.fmt.enable_modules : Set to true to build and provide the fmt C++ modules. If the compiler and C++ version don't support C++ modules (which is C++ > 20), this will result in a compilation failure. Set to true if $cxx.features.modules == true which means the configuration is set to enable C++ modules, false otherwise.
