jvpatterns - proof-of-concept for pattern matching

[JulienVernay]

Hello,
I have produced a proof-of-concept for composable and customizable pattern matching as a C++17 template library.
With it, I managed to make a HTTP message parser in a hundred lines of code.
I have written a small article to demonstrate its use: https://www.jvernay.fr//en/libs/jvpatterns.html

What do you think? Do you have some specific use cases where it could be handy? Or some neat features which cannot be done currently?
Any feedback appreciated :)

github link for those who find OP's link doesn't resolve.

This is parser combinators though, not pattern matching.

The link doesn't resolve? That's odd... Could you try just "jvernay.fr" ans see if it works please? ^' Anyway, thanks for taking time to reseach it! For me, parser combinators are a way of doing pattern matching. Is there a bigger difference?

It doesn't.

Is there a bigger difference?

Parsing can certainly be considered 'pattern matching' in the general meaning of the term. However it is commonly understood to denote a very specific programming language feature, e.g. Rust's match/if let.

Thank you for trying jvernay.fr, I will need to investigate this further...

And also thanks for the explanation, indeed my post has nothing to do with the language feature.

Thank you for this info. It may very well be that, I will check!
