"OCR" letter recognition for Advent of Code puzzles, compatible with all puzzles from 2015 to 2019. Also comes with a handy command line utility to parse the ASCII art directly from stdin:
$ cat abc.txt
.##..###...##.
#..#.#..#.#..#
#..#.###..#...
####.#..#.#...
#..#.#..#.#..#
#..#.###...##.
$ cat abc.txt | advent-of-code-ocr
ABC
To use as a library, add advent-of-code-ocr as a hackage dependency like you would any other.
To use as an executable:
# using stack stack install advent-of-code-ocr # using cabal cabal install advent-of-code-ocr # from source git clone https://github.com/mstksg/advent-of-code-ocr cd advent-of-code-ocr cabal install # or stack install
Should be compatible with all challenges from 2015 to 2021. However, I have only tested it with:
And it is possible I have missed some. If you notice any I am missing, please let me know!
