Ask HN: In which programming language is it better to make your own language?

This doesn't answer your question. But it would be an interesting project to try and make a programming language where you as the dev only and solely use an llm to do all the work.

So then you could say it was programmed in english*

*Or whatever human language you want.

I used lexy, which is a great C++ parser combinator.

I then used python match syntax to convert my ast to C.

Some years ago I used the Python library Lark (https://github.com/lark-parser/lark) to parse my programming language. It lets you write your grammar in basically EBNF, builds parse trees (that you can automatically reduce by removing leaves for parentheses, for example) and generates standalone pure-Python LALR(1) parsers for your grammar. Back then, I had a blast with it, it was fast, super easy to use and just worked. Now it's got 5k stars and seems to be a mature and production-ready library.

Thus, I vote Python: it has this amazing parser library, it's garbage-collected (no need to fiddle with memory allocations, like in C), it's dynamically typed (so you basically don't need to think about types at all), it now has a `match` statement (!) that makes it super easy to dissect your parse trees and abstract syntax trees.

Use C++ with one of the following:

Boost.Spirit https://www.boost.org/library/latest/spirit/ Boost.Parser https://www.boost.org/library/latest/parser/ (which I think succeeds Boost.Spirit Boost.Metaparse: https://www.boost.org/doc/libs/latest/doc/html/metaparse.htm...

All of these allow you to build a parser using C++ syntax and then add semantic or composed actions.

Prototype in Python with PLY (https://github.com/dabeaz/ply) or you could try Raku (https://raku.org/) which has nice functionality for building grammars.

After you know what you want to build, you could convert it to C, C++, or Rust to make it fast.

OCaml

Well, ANTLR[0] includes many programming language targets. I can also recommend OMeta [1] for quick prototyping. Other developers has implemented it in JS, .NET, etc. I just found Panini[2] in Rust but I am sure you can find others[3].
