  3. {fmt}

    A modern formatting library

    Project mention: Why {fmt} Is Trending Again: Safer, Faster C++ Output | dev.to | 2026-09-04

    That is why {fmt} is interesting again. The library appeared in GitHub Trending today, but its real story is not novelty. It is a mature answer to a stubborn engineering problem, and much of its design influenced std::format and std::print in modern C++.

  4. RE2

    RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library.

    Project mention: How to Install C++ Libraries with Bazel - RE2 Example | dev.to | 2025-12-30
  5. Cppcheck

    static analysis of C/C++ code

  6. opencv

    OpenCV Bindings for node.js

  7. nan

    Native Abstractions for Node.js

  8. pdqsort

    Pattern-defeating quicksort.

    Project mention: [Learning Documents] [Golang] Go 1.19 Sort is Faster | dev.to | 2026-01-11

    title: [Learning Document][Golang] Go 1.19's Sort is Faster published: false date: 2022-08-18 00:00:00 UTC tags: canonical_url: http://www.evanlin.com/til-go-pd-quicksort/ --- ![image-20220819163803756](http://www.evanlin.com/images/2021/image-20220819163803756.png) ## Go 1.19's Sort is Faster Go 1.19's Sort has been changed from QuickSort to Pattern-Defeating #Quicksort, the same as #Rustlang and C++ #Boost. If you want to know more about PD Quicksort, you can [refer to this article by the ByteDance team ""Building the fastest sorting algorithm for Go language"" (Simplified Chinese)](https://blog.csdn.net/ByteDanceTech/article/details/124464192) ### Quick explanation of what PD Quicksort is? - Optimized from QuickSort, best case from O(n log n) –> O(n) - Worst case O(n log n) ## Related articles: - Image from slides (Japanese): [https://speakerdeck.com/po3rin/go1-dot-19decai-yong-sareta-pattern-defeating-quicksort-falseshao-jie](https://speakerdeck.com/po3rin/go1-dot-19decai-yong-sareta-pattern-defeating-quicksort-falseshao-jie) - Algorithm implementation: [https://github.com/orlp/pdqsort](https://github.com/orlp/pdqsort) - Author's explanation video: [https://www.youtube.com/watch?v=jz-PBiWwNjc](https://www.youtube.com/watch?v=jz-PBiWwNjc) - [Golang's sorting algorithm will be changed to pdqsort, LLVM libc++ changed to BlockQuicksort](https://blog.gslin.org/archives/2022/04/22/10673/golang-%E7%9A%84%E6%8E%92%E5%BA%8F%E6%BC%94%E7%AE%97%E6%B3%95%E5%B0%87%E6%8F%9B%E6%88%90-pdqsort%EF%BC%8Cllvm-libc-%E6%8F%9B%E6%88%90-blockquicksort/)

  9. AppSignal

    AppSignal knows why the f*#k it crashed. Stop vibe-debugging. Every exception, every backtrace, grouped so you see patterns, not noise.

  10. Serial Communication Library

    Cross-platform, Serial Port library written in C++

  11. webworker-threads

    Lightweight Web Worker API implementation with native threads

  12. Better Enums

    C++ compile-time enum to string, iteration, in a single header file

  13. Mach7

    Functional programming style pattern-matching library for C++

  14. Experimental Boost.DI

    C++14 Dependency Injection library

  15. UNITS

    a compile-time, header-only, dimensional analysis and unit conversion library built on c++14 with no dependencies.

  16. stdman

    Formatted C++20 stdlib man pages (cppreference)

  17. PythonMonkey

    A Mozilla SpiderMonkey JavaScript engine embedded into the Python VM, using the Python engine to provide the JS host environment.

  18. constexpr-8cc

    Compile-time C Compiler implemented as C++14 constant expressions

    Project mention: Building a compiler that works at compile-time so you can compile your program while you compile your program. | dev.to | 2026-07-29

    I built a (mostly) full-fledged C compiler that runs entirely in constexpr. Why? No idea. Especially considering it's been done before, you can check out constexpr-8cc. But that one lacks C++ bindings and cross-platform support.

  19. outcome

    Provides very lightweight outcome<T> and result<T> (non-Boost edition)

  20. DynaMix

    :fish_cake: A new take on polymorphism

  21. STX

    C++17 & C++ 20 error-handling and utility extensions.

  22. cxx-prettyprint

  23. kangaru

    🦘 A dependency injection container for C++11, C++14 and later

  24. Stage

    Mobile robot simulator
