Hello world. I want to create a very tiny programming language (variables , conds, loops, and funcs) just to exercise my brain and learn more. I want to it to be both compiled and interpreted (as Dart). And I want to code it in...Nim.

Please, could you give advices, links to useful tutos and order resources, and a list of Nim's native libs that I have to study ? So long, I don't even know where to start. :-) Thanks in advance to all.

This book is a really good introduction to creating interpreted languages: http://craftinginterpreters.com/

I have list of libraries & different projects related to language development. Most likely you'd want to look at npeg for parsing as starting point.

There is also a #langdev channel on discord

Regarding npeg: while it's a good starting point for building a parser, in my own experience I found that building AST with it is quite difficult to do. Mainly because of how its code blocks work.

Thank you very much I'm reading the book. It's a real treasure.

If the syntax will be simple and similar to Nim's, you can use nim's Macro system to make one. I made a simple one for LOOP programs. I have no experience making "real" langauges
