Wren VS Advent-of-code

For a moment I thought it was about wren programming language... [1]

For "W" you could use Wren.

Bob Nystrom also has a blog, and his articles are really well written (see his post on Pratt parsers / garbage collectors). I'd also recommend going through the source code for Wren, it shares a lot of code with Lox. Despite the deceptive simplicity of the implementation, it (like Lox) is incredibly fast - it's a great way to learn how to build production grade compilers in general.

Only kind of unrelated ... Every time I see the Bevy logo I'm reminded of Wren language https://wren.io/

If you want a pure C99 (sadly not C89 like Lua) immensely fast embeddable language pure interpreter, wren is a great language with excellent features like overload by arity. There is a huge maturity gap between the languages tho.

Check out the source to Wren: https://wren.io. It’s from the author of Crafting Interpreters and builds directly on what’s discussed in the book (essentially a more complete Lox) and adds several additional types, including an array.

The best C code I have ever read is that of wren.

Wow, almost identical to mine: https://github.com/MichalMarsalek/Advent-of-code/blob/master/2022/Nim/day6.nim

This year I was writing two sets of solutions in Nim. The first one focuses on idiomatic, nice and short and readable Nim. The other focuses purely on speed. The combined running times of the fast solutions is 130 ms. Please let me know if you have any tips on how to make my solutions more simple and/or idiomatic.

Beautiful Nim! My solution is actually very similar.
