Advent of Code 2022 in Zig!

This repo contains my solutions to the AoC'22 challenge, written in Zig. Just wanted to learn the language.

It should work with Zig 0.11.0 (I'm running 0.11.0-dev.1797+d3c9bfada).

The Curious Case of a Memory Leak

My Day 23 implementation led to an informative adventure, and I wrote a blog post about it.

Random thoughts on Zig

Note that these are just my impressions centered around what I want from a language; your mileage may vary.

The good

• Auto-union error types are amazing! Very ergonomic compared to Rust
• defer and errdefer are nice
• Explicit allocators everywhere- really makes you think about the memory allocation patterns in your code
• XXXAssumeCapacity class of functions for non-allocating modifications of dynamic data structures are good to have. This lang is geared towards perf. (But they also add to the noise in editor autocompletions- there's (at least) two versions of every method.)
• enums are fun; . is easier to type than :: (as in Rust, C++)

The not so good

• I would not want to read the code I've written. Unnecessary verbosity at various places (struct fields initialization, no operator overloading, while loops).
• comptime was too hard to get started- bad error messages from compiler, random limitations, etc.
• format function seems hacky... In general, anytype is reminiscent of C++ template hell. No autocomplete :(
• ugly multiline strings
• ZLS/docs still have a lot of work to do
