Show HN: Less Slow C++
The problem can occur in general if there is a greedy match within the regex: https://github.com/hanickadot/compile-time-regular-expressio...
Although it looks like that this got fixed for simple patterns.

Implementing Regular Expressions in TypeScript Types (Badly)
Hana Dusikova did this in C++ several years ago, with her CTRE library.
https://github.com/hanickadot/compile-time-regular-expressio...
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?
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

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.
