OCR for Advent of Code puzzles
Crate to convert Advent of Code from ASCII letters to characters. This is required for several of the puzzle days through the years, including: 2016/09, 2019/08, 2019/11, 2021/13, and 2022/10.
This has been made to help automate parsing of those puzzles for my own AoC solutions, but are shared for others interest.
Installation
cargo install advent-of-code-ocr
Usage
The main function to parse a screen from AoC is the parse_string_to_letters.
use advent_of_code_ocr::parse_string_to_letters;
// Input is:
// ####.###....##.###..###..#..#..##..#..#.
// #....#..#....#.#..#.#..#.#.#..#..#.#..#.
// ###..#..#....#.###..#..#.##...#..#.####.
// #....###.....#.#..#.###..#.#..####.#..#.
// #....#....#..#.#..#.#.#..#.#..#..#.#..#.
// ####.#.....##..###..#..#.#..#.#..#.#..#.
let input = "####.###....##.###..###..#..#..##..#..#.\n#....#..#....#.#..#.#..#.#.#..#..#.#..#.\n###..#..#....#.###..#..#.##...#..#.####.\n#....###.....#.#..#.###..#.#..####.#..#.\n#....#....#..#.#..#.#.#..#.#..#..#.#..#.\n####.#.....##..###..#..#.#..#.#..#.#..#.";
assert_eq!(parse_string_to_letters(input), "EPJBRKAH");
Two other functions are exposed by this crate:
parse_letterwhich tries to convert a single AoC character to aOption<char>split_screenwhich splits a full AoC screen to individual AoC characters.
