About

This crate provides a very minimal set of utils to get started with writing Advent of Code solutions.

AocCommand

Description

This is a CLI command builder that provides an input source (either a file or STDIN). The suggested workflow is to create a Rust project with one binary per AOC solution.

Here is an example help printout generated from a program generated by AocCommand:

Example description

USAGE:
    prog [FILE]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

ARGS:
    <FILE>    Input file (defaults to STDIN if not provided)

Usage

Collect all lines from input:

use std::io::BufRead;
use aoc_utils::AocCommand;

let input = AocCommand::new("Example solution").parse_args().unwrap();
let lines: Vec<String> = input.lines().map(Result::unwrap).collect();

for line in lines {
    println!("{}", line);
}
