The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The issue of unit tests and performance measurements (Benchmark)
An alternative is tracking the number of instructions a test executes: https://github.com/martinus/nanobench

how do you properly benchmark?
Nano bench is a great library with low overhead. https://github.com/martinus/nanobench

Much Faster than std::string, fmt::format, std::to_chars, std::time and more?
I've done a relatively simple test of taking random doubles (between 0 and 1), converting them to a C string via std::to_chars and then converting that C string back to a double via std::from_chars vs his xeerx::chars_to and got the following results on my machine via nanobench:

Can you give an example of well-designed C++ code, and explain why you think it is so?
I like https://nanobench.ankerl.com/

Best accurate way to measure/compare elapsed time in C++
Of course, the best way to benchmark is nanobench: https://nanobench.ankerl.com/

The 23 year-old C++ developers with three job offers over $500k
I've created robin-hood-hashing and nanobench, and recently made some contributions to Bitcoin and doxygen

I don’t know which container to use (and at this point I’m too afraid to ask)
Right. Regex runtime construction is known to be slow, so ideally the state machinery construction is built at compile time (boost.xpressive, ctre). Also, boost.regex is faster than most of the std implementations if compile time isn’t possible. And if that’s no good rewrite without regex. Since it sounds like it’s all encapsulated at least it would be easy to measure the options. These days I use this one to compare https://nanobench.ankerl.com/

I'm writing a microbenchmarking library called "precision" without any macros. What do you guys think of the API?
You can check the API of nanobench which also doesn't use macros, as far as I have used it.

C++20 std::format is 2x slower than std::fstream?
I've tried again with your latest changes and decided to use https://github.com/martinus/nanobench for a better benchmark and got the following output:

- Why Windows isn't ready for Arm developers
- Root cause of log4j: format string is a historical mistake. fast_io is the future.

- What does the keyword "inline" REALLY mean in C++?? You are highly likely to misunderstand it!
- C++ exceptions under the hood
- Fast_io and refterm v2 is 46548 times faster than stdio.h and cmd
-
fast_io + refterm v2 is 46548 times faster than stdio.h + cmd
Ah, fair enough! Happen to have a link to an example / docs? I can't really make heads or tails of the examples/docs and I don't really spend much time worrying about optimizing I/O in C++ to have enough context. I assume something to do with open_mode?
What are some alternatives?
