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.

Why are strings and IO so complicated?
CTRE (https://github.com/hanickadot/compile-time-regular-expressions) ranges::views (filter, transform, etc.) (C++20) str.find() + str.substr() freopen to stdin + cin >> extraction Parser libraries
- Compile time regular expression in C++

What are thoughts on removing regular expression from the standard library?
There are suggestions that should be replaced by the high performance ctre implementation: https://github.com/hanickadot/compile-time-regular-expressions
-
What's the most hilarious use of operator overloading you've seen?
operator"" can be used in a similar way to expression templates (DSLs), where the type of the resulting expression is dependent on the string contents. For example ctre makes use of this to build efficient regular expression parsers, and kumi uses this in conjunction with operator[] to make tuple indexing quite elegant

It's easy, I swear! Once you learn a bit about it, you'll be amazed!
Check out https://github.com/hanickadot/compile-time-regular-expressions anything is possible 😂

Verify all characters are same except a few
Yes to regex, no to std::regex. Better to use CTRE. Something like "^Hello [0-9]+ how are you" should allow checking if there's a match
-
Constexpr regex parser!
You could compare your implementation with https://github.com/hanickadot/compile-time-regular-expressions and see if there are any ideas you can copy.
- Regex is comically slow. High performance alternatives? (Pattern matching for validation)
-
Regex shootout updated - hyperscan 1st, Rust 2nd, std::regex dead last
std::compile_time_regex would be a nice addition. Something similar to ctre https://github.com/hanickadot/compile-time-regular-expressions Simply letting the compiler generate all the regex parsing machinery at compile time.... And benefitting from compiler optimizations, vectorization, etc...

What are some cool modern libraries you enjoy using?
ctre
What are some alternatives?
PEGTL - Parsing Expression Grammar Template Library
RE2 - RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library.
nanobind - nanobind: tiny and efficient C++/Python bindings
consteval-huffman - Compile-time Huffman coding compression using C++20
envpool - C++-based high-performance parallel environment execution engine (vectorized env) for general RL environments.
xorstr - heavily vectorized c++17 compile time string encryption.
Magic Enum C++ - Static reflection for enums (to string, from string, iteration) for modern C++, work with any enum type without any macro or boilerplate code
neo-fun - Some library components that didn't quite fit anywhere else...
entt - Gaming meets modern C++ - a fast and reliable entity component system (ECS) and much more
C++ Format - A modern formatting library
uvw - Header-only, event based, tiny and easy to use libuv wrapper in modern C++ - now available as also shared/static library!
staticvec - Implements a fixed-capacity stack-allocated Vec alternative backed by an array, using const generics.
