Advent of Code 2022

Usage

To run a solution:

  • Clone the repo
  • Place input/example files under input/<solution-name-without-extension>/<input-name>.txt
  • Run cargo run -- <solution-file-name> <input-name>

Currently native Rust modules and Prolog scripts are supported as solutions. The build script will generate logic for calling any day_X.rs or day_X.pl found in the src/ directory.

Rust solutions must export a solve function:

pub fn solve(_: BufReader<File>) { /* ... */ }

Prolog solutions must define a predicate run/0 and read the input file path from stdin:

run :-
    read_term(InputPath, []),
    % ...
    halt.

By default, Prolog scripts are run with scryer-prolog, but this can be overriden by setting PROLOG to a path to an interpreter.
