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.

Implementing Regular Expressions in TypeScript Types (Badly)
Hana Dusikova did this in C++ several years ago, with her CTRE library.

Of course, it has all the usual tradeoffs of compile-time template programming.

Giving C++ std:regex a C makeover
entirely. Good alternatives are CTRE (https://github.com/hanickadot/compile-time-regular-expressio...) which parses the regex and instantiates the automaton entirely at compile-time, or Google's re2 (https://github.com/google/re2) if you need to generate regular expressions at run-time.

Why are strings and IO so complicated?

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)
What are some alternatives?
When comparing RegExtract and compile-time-regular-expressions you can also consider the following projects:
Gigantor - Works in conjunction with System.Text.RegularExpressions.Regex to boost performance, add a replace function, and support gigantic files that exceed RAM
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.
oniguruma - regular expression library
staticvec - Implements a fixed-capacity stack-allocated Vec alternative backed by an array, using const generics.
rxcg - A regular expression matcher generator for C
bit_set - Rebooting the std::bitset franchise
