advent of zig

Structure

This repository holds solutions to Advent of Code puzzles written in the programming language Zig.

src holds all source code files. main.zig is the main program. It uses aoc.zig as a library where each daily puzzle has a function called as the puzzle itself. The convention is that this function returns a Solutions struct that holds two numbers: the solution to the first part of the puzzle, and the oslution to the second part. main only needs to invoke the correct function following the command line flags set by the user, and then to print the solution numbers out.
var/data holds data for puzzle inputs as .txt files. Each daily puzzle is in its own subdirectory, under <year>/<day>.
libs holds all dependencies of the project, as vendored git submodules. This worked better than using the recently released package manager.

$ git submodule init
$ git submodule update
$ zig build

Submodules are not needed for every puzzle, but the build will not succeed without the declared dependencies.

$ zig build test

The test step is added to the normal build on build.zig by the default template.
