Modules in using std::cpp 2026 C++20 modules have been in the standard for 6 years already, but we’re not seeing widespread adoption. The ecosystem is still getting ready. As a quick example, import std, an absolute blessing for compile times, requires build system support, and this is still experimental as of CMake 4.3.1. And yet, I’ve realized that writing module-native applications is really enjoyable. The system is well-thought and allows for better encapsulation, just as you’d write in...

In my last post I mentioned that int128 library would be getting CUDA support in the future. The good news is that the future is now! Nearly all the functions in the library are available on both host and device. Any function that has BOOST_INT128_HOST_DEVICE in its signature in the documentation is available for usage. An example of how to use the types in the CUDA kernels has been added as well. These can be as simple as: using test_type = boost::int128::uint128_t; __global__ void cuda_mu...

This quarter, I focused on two areas of Mr.Docs: adding first-class support for function objects, the pattern behind C++20 Niebloids and Ranges CPOs, and overhauling how the tool turns C++ metadata into documentation output (the reflection layer). Function objects: documenting what users actually call In modern C++ libraries, many “functions” are actually global objects whose type has operator() overloads. The Ranges library, for instance, defines std::ranges::sort() not as a function templ...

During Q1 2026, I’ve been working in the following areas: boost::container::hub boost::container::hub is a nearly drop-in replacement of C++26 std::hive sporting a simpler data structure and providing competitive performance with respect to the de facto reference implementation plf::hive. When I first read about std::hive, I couldn’t help thinking how complex the internal design of the container is, and wondered if something leaner could in fact be more effective. boost::container::hub crit...

Code Coverage Reports - designing new GCOVR templates A major effort this quarter and continuing on since it was mentioned in the last newsletter is the development of codecov-like coverage reports that run in GitHub Actions and are hosted on GitHub Pages. Instructions: Code Coverage with Github Actions and Github Pages. The process has really highlighted a phenomenon in open-source software where by publishing something to the whole community, end-users respond back with their own suggestio...
