# advent-of-code-ocr
"OCR" letter recognition for [Advent of Code][aoc] 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:
[aoc]: https://adventofcode.com
```
$ cat abc.txt
.##..###...##.
#..#.#..#.#..#
#..#.###..#...
####.#..#.#...
#..#.#..#.#..#
#..#.###...##.
$ cat abc.txt | advent-of-code-ocr
ABC
```
## Installation
To use as a library, add *advent-of-code-ocr* as a hackage dependency like you
would any other.
To use as an executable:
```bash
# 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
```
## Compatibility
Should be compatible with all challenges from 2015 to 2019. However, I have
only tested it with:
* 2016 Day 8
* 2018 Day 10
* 2019 Day 8
* 2019 Day 11
And it is possible I have missed some. If you notice any I am missing, please
let me know!
