In the fourth quarter of 2023 the functionality for direct parsing in JSON was finalised and the code was merged into the mainline and then released in Boost 1.84.0. Thus, I’ve moved to the natural opposite of direct parsing: direct serialisation. Boost.JSON’s serialisation is less customisable then parsing, since the demand for custom serialisation is significantly lower. As a result, the design of the serialiser is quite different from that of the parser, and hence a different approach had ...

Wrote a section on the Super-project, based on some legacy Wiki pages that needed considerable updating, and the boostdep tool steps as this covered installing the necessary components. Covered four main topics: the Super-project layout, Getting Started, Library Maintenance and Library Workflow. Wrote a Best-Practices section on Beneficial Dependencies - the dependencies used by the most libraries of Boost. These include Boost.Config, Boost.Core, Boost.Assert, Boost.StaticAs...

Here’s an overview of some projects I have been working on the last few months. Doc Previews A Jenkins server is building “pull request doc previews” for multiple boost repositories. If any Boost author is interested in “doc previews” let me know. Specific previews: adding an Antora version to boostorg/url. Upgraded the server packages, apps, and operating system to Ubuntu 22.04. Mr. Docs has a dedicated server for docs testing. Debugged CI deployment issues there. JSON benchmarks http...

In spite of it being winter here, Boost.MySQL is presenting a new pool this year! This was one of the most requested features in the library, and will finally be generally available as an experimental feature in Boost 1.85. Connection pools manage tasks that are easy to get wrong, like reconnections, health checks and session cleanup. As they reuse physical connections, they also provide a nice efficiency boost. Using a pool is as simple as: boost::asio::awaitable<std::int64_t> get_n...

Over the past few months I have been working on a number of libraries both for proposal to, and currently in Boost. New Libraries Charconv The Charconv (https://github.com/cppalliance/charconv) review period is scheduled for 15 - 25 Jan 2024. Directions for use with B2, VCPKG, and Conan are provided to allow for testing, and evaluation of the library. All feedback is welcome and appreciated. Reviews can be submitted to the mailing list or the Review Manager, Chris Kormanyos at e_float@yaho...
