The branch is used to test the compiler support of C++20 modules, explore the practice with C++20 modules and compare the coding style between header based and named module based.
The modules code lives in *_module direcotories. The third_party_module/stdmodules
provides an implementation for std modules. The third_party_module/asio provides an
implementation for a named wrapper for the asio library. Both the std modules and async_simple
modules are wrappers for header in fact. The async_simple_module provides
async_simple module, which rewrites the whole implementation by named modules. We could
find the practice of named modules in it. The async_simple_module/test tests that the runtime
behavior is still fine. The demo_example_module provides some demo examples
(including some sync/async http client/servers) by using async_simple module, std module and
asio module.
Compiler: clang15.x or higher versions STL Libraries: libstdc++10.3, libc++15.x or higher versions. Other dependencies: gtest, gmock
Now we can use cmake (higher or equal than d18806e67336d96a9a22b860), xmake (higher or equal than 0eccc6e) and Makefile to build this demo.
If you choose cmake or xmake to build the project, the compiler should be clang16 (or higher than 64287d69827c).
make -j
xmake && xmake -r
mkdir build_cmake && cd build_cmake
cmake .. -GNinja
ninja
ninja test
This method will download gtest automatically. In case it is problematic to download gtest, we can specify the location
of gtest by cmake variables: -DGMOCK_INCLUDE_DIR=<path-to-headers of gtest> -DGTEST_INCLUDE_DIR=<path-to-headers of mock> -DGTEST_LIBRARIES=<path-to-library-of-gtest> -DGMOCK_LIBRARIES=<path-to-library-of-gmock>.
