compile-time-regular-expressions VS flux

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

There are suggestions that should be replaced by the high performance ctre implementation: https://github.com/hanickadot/compile-time-regular-expressions

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

Check out https://github.com/hanickadot/compile-time-regular-expressions anything is possible 😂

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

You could compare your implementation with https://github.com/hanickadot/compile-time-regular-expressions and see if there are any ideas you can copy.

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...

ctre

flux (https://github.com/tcbrindle/flux) (like ranges::views)

Some people are "Rustifying" their C++ programs also. C++ tooling keeps getting better and libraries like Flux are coming on-line.

Have I got just the thing for you

The code is available on Github of course if you want to check it out, and there's a little bit of documentation covering some of the sequence adaptors and algorithms which are available.

What I've been doing in my projects lately is bundling catch.hpp, then compiling a single catch_main.cpp as a static lib which links to my test exe, and also precompiling catch.hpp when CMake is new enough. You can see an example here.
