There are also other approaches. Macro variants making use of `__VA_ARGS__` would be probably the best trade-off. If you want a slightly more ergonomic syntax, something like Metalang99 [1] will help (and the author even wrote a post about this exact subject [2]). Codegen is another option which may work better than other options depending on the situation and exact implementation strategy. And there is always the Reflection TS [3], which may or may not be incorporated to C++26...

Project mention: How Much Memory Do You Need to Run 1M Concurrent Tasks? | news.ycombinator.com | 2023-05-21It would be interesting to bench something extremely lightweight (like https://github.com/edubart/minicoro) against these runtimes.
By my back-of-the-napkin math, 1,000,000 coroutines would cost about 64mb + 2mb/core for stacks.. which works out to about 4x less memory than the 'winner' of this comparison, and ~30x less than go.

Project mention: A header-only C implementation of C++ <algorithm> | news.ycombinator.com | 2023-07-03Well, I do like mine better, which is closer to the STL, and for all containers. https://github.com/rurban/ctl/
Project mention: Show HN: RK Test, a Google Test style library written in C99 | news.ycombinator.com | 2023-12-11I really like Google Test, but am planning on doing some embedded development in C, where I sometimes find it awkward to test C code using a C++ library.
Therefore, I wrote a small unit test library closely mimicking Google Test. It consists of two source files, "rktest.c" and "rktest.h", and is about 1k lines of code and written in C99.
It uses a trick for self registering tests by placing pointers to the unit test functions into a known place in program memory, that I first learned about from https://github.com/christophercrouzet/rexo/ and https://github.com/Snaipe/Criterion/.
Project mention: How do crypto functions deal with the issue of character size? (e.g. Unicode) | /r/cryptography | 2023-06-18Hey guys. If you remember me from several months ago, with this object de art, I am here with a less cringy question than that of 'I made a hash function!!!111'. I apologize if this question is basic btw. My question is, how do crypto functions, of any kind, deal with character size? For example in C, wchar_t is either 2 or 4 bytes. So, if the implementation goes through the stream like stream++ it will be stepping word-wise not byte-wise. And then if another machine, using a different implementation, reads the stream byte-wise and not word-wise, then it won't get the same message right?
