I wanted to write some zig so I ported https://github.com/happyleavesaoc/aoc-mgz.

I started the project by hand then had Claude do the rest, which it did a fine job on except the JSON serialization seems quite hacky.

It runs 15-20x faster than aoc-mgz and produces the same JSON file for 3 games that I played.

Most of the speedup was from replacing a regex with manual byte scan logic. I didn't spend tons of time optimizing.

To observe the speedup, compile with zig 0.14.1 (only tested version)

zig build -Doptimize=ReleaseFast

and then run with

.\zig-out\bin\zig14_basic.exe .\game2.aoe2record
