trebuchet

This folder contains a Logtalk solution for the Advent of Code 2023 Day 1 problem:

https://adventofcode.com/2023/day/1

The solution provided is for Part 2 of the problem. To solve just for Part 1, comment out the grammar rules for digits as letters.

The test_files directory contain sample inputs for part 1 of the problem copied from the problem description. For copyright reasons, the part 2 files cannot be distributed here and must be downloaded from the Advent of Code 2023 website.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

%versions

Start by loading the example:

logtalk_load(trebuchet(loader)).

Compute the calibration for the test_files/sample_1 file (part 1):

object_property(trebuchet, file(_, Directory)),
atom_concat(Directory, 'test_files/sample_1', File),
trebuchet::solution(File, Calibration).

Compute the calibration for the test_files/sample_2 file (part 1):

object_property(trebuchet, file(_, Directory)),
atom_concat(Directory, 'test_files/sample_2', File),
trebuchet::solution(File, Calibration).

Compute the calibration for the test_files/input file (part 2):

object_property(trebuchet, file(_, Directory)),
atom_concat(Directory, 'test_files/input', File),
trebuchet::solution(File, Calibration).
