  11. doctest

    The fastest feature-rich C++11/14/17/20/23 single-header testing framework

    Project mention: The Two Factions of C++ | news.ycombinator.com | 2024-11-24

    catch2 has become fairly bloated. doctest takes all of the best parts of catch2 without all the bloat and the end result is a test framework that is literally over 10x faster than catch2. It's also like 90% compatible with catch2 so porting your tests to it is pretty easy.

    Especially if you have a build process that always runs your unit tests, it's nice to have a very fast test/compile/debug loop.

    I'm definitely considering the same, and you're right - it's not C++ itself that appeals to me at all, it's the libraries. I'm not sure what C libraries I'd use for collections (instead of the STL and Abseil [0]), or in lieu of CLI11 [1] or Dear ImGui [2].

    Project mention: A Comparison of Arenas in Rust | news.ycombinator.com | 2024-08-25

    For example, here's the documentation[2] for a thread safe heterogeneous thread-aware memory and header[3] for the underlying thread safe pool.

    It uses a mutex, but at a glance only when it needs to consult the fallback allocator (which could involve a system call). If you knew that the fallback allocator were a pre-allocated arena, maybe you could do with atomics only. The free list is already lock-free, and so too could be the block list.
