"{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
Experimental C++20 modules support
Modules support is WIP, both in the build2
package and also in fmt
upstream. Latest versions of MSVC or Clang are recommended, and the most up-to-date version of the package with regards to modules compatibility can be used via git and the modules branch. For example, in project repositories.manifest
