PEGTL VS lexy

Very cool, and I like the name!

I'd be interested in reading about how Matcheroni compares with PEGTL and Lexy.

I found a library I wanted to test: Pegtl

I like PEGTL

As a professional C++ programmer I feel a lot of the reasons C++ gets this response is because it's simply not "batteries included" like Go or Rust.

C++ is a very powerful, unopinionated language, that gives you a lot of freedom to attack your problem domain the way you best see fit.

If you're writing a networked application, don't use POSIX sockets, go and find a higher level library. If you're parsing complex text formats, don't iterate over buffers with char*'s, go pick up PEGTL[0]. If you're working on graphs, or need to properly index in-memory data, go pick up Boost[1][2]. If you need a GUI, go pick up Qt.

It's extremely common in C++, due to the lack of a universal package management solution, for people to try and "muddle through" and do shit themselves when it's far outside their core competency.

At one of my last employers, the core product was parsing JSON with std::regex, simply because they couldn't be bothered to integrate a JSON library.

You are looking for Boost.Spirit (https://www.boost.org/doc/libs/1_76_0/libs/spirit/doc/x3/html/index.html) or PEGTL (https://github.com/taocpp/PEGTL)

I personally prefer to use parsing combinator libraries in C++, where the "grammar" is just part of normal C++ and directly integrate. Examples are Boost.Spirit, pegtl, or (my own) lexy.

In case you are still fighting with left-recursion you might be interested in this: https://github.com/taocpp/PEGTL/blob/master/src/example/pegtl/lua53.hpp

I've found https://github.com/taocpp/PEGTL to be easier to use than boost parser generators.

https://github.com/foonathan/lexy nakon sto sam se propatio sa errorima od boost spirita, a pegtl mi se nije svidao, ovaj library je dosao kao odusevljenje, a i dokumentacija je iznenadujuce ok

This might be closer: https://github.com/foonathan/lexy

There is an example for a simple calculator and a shell like language with string interpolation.

I've been going over lexy (https://github.com/foonathan/lexy) with that list in mind:

I'm working on a C++ parser combinator library lexy, which has error recovery.

You can check Lexy library of Foonanthan. https://github.com/foonathan/lexy : it is pretty nice, and light and support if i don't miss, C++20
