"{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
:
:
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
.
