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:

:
role: prerequisite
location: https://github.com/build2-packaging/fmt.git#modules

Enable with config.cxx.features.modules=true. When enabled, by default dual mode is used meaning that the library can be consumed either through import or via #include. To enable this safely, all entities are attached to the global module (extern "C++"). See modules_only option for the alternative.

• config.fmt.enable_import_std : Set to true to consume the standard library as a module when building the fmt module. Support dependent on compiler and std lib. Defaults to false.
• config.fmt.modules_only : Set to true to enable modules-only mode for the package. In this mode, fmt entities are fully encapsulated in the fmt module meaning #include-based consumption cannot be mixed, and the package will not export headers. Defaults to false.
