[review] [hub] boost::container::hub review starts on April 16
by Ion Gaztañaga 15 Apr '26

15 Apr '26

Dear Boost community, The formal review of Joaquín M. López Muñoz's boost::container::hub container is scheduled for April 16 - April 26. Hub is a nearly drop-in replacement of C++26 std::hive that has excellent performance. https://github.com/joaquintides/hub/blob/develop/README.md#performance The codebase is fairly small (single 1800-LOC header), and due to the subject matter, it is proposed to be part of Boost.Container rather than as a separate library. You can find code and documentation here: https://github.com/joaquintides/hub Best, Ion

(Boost) Reflecto
by Emil Dotchevski 13 Apr '26

13 Apr '26

I wrote a small constexpr type/enum reflection library which I think may be a good addition to Boost. It needs C++17, although it relies on implementation-specific support (works on gcc, clang and msvc). https://github.com/zajo/reflecto

std::core_dump() Issue 2 — Now Focused on the Boost Community
by Mark Cooper 08 Apr '26

08 Apr '26

Hi all, Issue 2 of the std::core_dump() newsletter is out: https://dl.cpp.al/newsletters/boost-newsletter-2026-03.pdf We've expanded the newsletter's focus from C++ Alliance news to the Boost community as a whole. Highlights: - Boost.URL constexpr URL parsing — malformed literals now fail at compile time, not runtime - Boost Docs Localization Pipeline — translation workflow piloted on Boost.JSON and Boost.Unordered If you'd like to contribute to next month's issue, reach out!

[msm] Antora documentation should reverted
by Vinícius dos Santos Oliveira 08 Apr '26

08 Apr '26

It's fully broken. Compare this: https://www.boost.org/doc/libs/1_90_0/doc/antora/msm/reference/euml-operato… To this: https://www.boost.org/doc/libs/1_89_0/libs/msm/doc/HTML/ch10.html It's clear that nobody took the time to review the output of whatever tool was used to auto-convert the old thing to Antora. This isn't the only place where the Antora version is broken.

[math] Remez algorithm in Boost Bessel implementation
by znailcode＠gmail.com 02 Apr '26

02 Apr '26

Hi, I am currently working on the Struve function implementation alongside the Bessel functions. To approximate H₀(x) and H₁(x), I plan to use the Remez minimax approximation algorithm, similar to what is used in the current Bessel implementation: https://github.com/boostorg/math/blob/develop/include/boost/math/special_fu… (for example, in the region x ≤ 8). I see that an implementation of the Remez algorithm already exists in Boost here: https://github.com/boostorg/math/blob/develop/include_private/boost/math/to… I would like to ask which implementation of the Remez algorithm was used to derive the Bessel function approximations. Was it this Boost implementation, or a different one? Additionally, how were the reference values computed for the approximation process? Currently, I am using mpmath in Python to generate reference values for the Struve function with the required precision. Best regards, Zaripov Nail
