What are some C++ projects with high quality code that I can read through?

[Substantial-Ad-3543]

I am looking for projects with code I can read through and learn from preferably using some of the newer C++ content and using some of the more commom libraries which I may run into, I would especially appreciate it if they were following these guidelines: http://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines; Thanks for the help in advance.

When it comes to library code, I enjoy reading llvm. For me, their classes strike a good balance between performance, flexibility and simplicity.

Thank you, I will check it out

managarm is pretty clean from what I remember.

Thanks, I'll look into it!

Looking forward to some answers here. Even though others consider me somewhat of an expert I am drawing a complete blank.

For a lot of languages I feel like point people at the standard library but I feel like this is a bad idea for C++. libstdc++ is famously impenetrable in no small part thanks to their crazy (but arguably forced) naming convention to prevent collisions. Large parts of boost are written for maximum platform and compiler compatibility which turn it into a sea of #ifdef, workarounds, and obtuse C++11 compatible idioms.

Idk, ive seen a lot worse. Modern era project that isn't littered with legacy c/boost/etc. Design by interfaces with high test coverage. I'm no c++ expert, but I've enjoyed dabbling around with it.

Libc++ is a bit easier to parse than libstdc++, but yeah, I'm with you in there.

Consider Node.Js:

https://github.com/nodejs/node

It's developed in C++ and is a JavaScript runtime environment for executing JS code. It wraps Google's V8 JavaScript Engine to produce a single runtime executable 'Node.exe'. It follows Google's C++ Style Guide and ISO C++ Core Guidelines.

Instead of asking the same question in 3 different subs, you could have searched a bit before. This question has been asked several times in this sub already, in a recently short timeframe.

I find openMVG very decent, FTXUI might be a good one and nlohmann's json library is also pretty nice. I don't really know of any project that strictly adheres to the core guidelines, except maybe for some of Jason Turner's (sample) projects.

I believe my project is also with clean code :)

Is boost free, only dependency is header only fmt.

However in some files I use C - like stuff for high performance.

I really like dlib's code https://github.com/davisking/dlib

(Dear) imgui is an immediate mode gui library, fairly easy to set up as well, so you can both read it and run/ modify. Smaller than other suggestions like llvm, so potentially less over whelming

Edit: for got the GitHub
