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.
sh
cargo install advent-of-code-ocr
The main function to parse a screen from AoC is the parse_string_to_letters.
```rust use adventofcodeocr::parsestringtoletters;
// Input is: // ####.###....##.###..###..#..#..##..#..#. // #....#..#....#.#..#.#..#.#.#..#..#.#..#. // ###..#..#....#.###..#..#.##...#..#.####. // #....###.....#.#..#.###..#.#..####.#..#. // #....#....#..#.#..#.#.#..#.#..#..#.#..#. // ####.#.....##..###..#..#.#..#.#..#.#..#. let input = "####.###....##.###..###..#..#..##..#..#.\n#....#..#....#.#..#.#..#.#.#..#..#.#..#.\n###..#..#....#.###..#..#.##...#..#.####.\n#....###.....#.#..#.###..#.#..####.#..#.\n#....#....#..#.#..#.#.#..#.#..#..#.#..#.\n####.#.....##..###..#..#.#..#.#..#.#..#.";
asserteq!(parsestringtoletters(input), "EPJBRKAH"); ```
Two other functions are exposed by this crate:
parse_letter which tries to convert a single AoC character to a Option<char>split_screen which splits a full AoC screen to individual AoC characters.
