Ask HN: Which open source project's C++ code is pleasure to read?

The SFML game engine is very well written and documented, definitely a pleasure to read. https://github.com/SFML/SFML

I recommend taking a look at this: https://github.com/fffaraz/awesome-cpp

It's a very well curated list containing both older and more recent projects realized in C++, neatly separated into categories.

Which of these projects have code that is easy and pleasurable to read?

I like this:

https://github.com/niklasso/minisat

It is a great example of academic code which is used in research but is also pedagogical. If all C++ was like that I don't think anybody would have a problem with C++!
