advent_puzzle

Simple helper class for parsing and running Advent of Code puzzles.

This will parse the data file in a few ways then call your processing function. Since each day has 2 puzzles (referred to here as A and B for simplicity), you can specify separate runners for each type.

Usage

1. Create a new Puzzle

   const Puzzle = require('@thefotios/advent_puzzle');
   const p = new Puzzle({
     // Each line is comma separated (with spaces)
     delimiter: /,\s+/,
     // Parse each element as an Integer
     numeric: true,
   });

2. Define processors. These can also be passed into the constructor.

   Valid Processors are run in the following order:

   Key	When it's run
   before	After parsing the data, but before each puzzle
   A or B	Run depending on which puzzle is passed in the args
   after	After the A or B processor is run
   logger	Last, by default will console.log data

   // Add elements of each line
   p.A = lines => lines.map(data => data.reduce((acc, x) => acc + x, 0));
   
   // Multiply elements of each line
   p.B = lines => lines.map(data => data.reduce((acc, x) => acc * x, 1));
   
   // Sort the results of each line (descending)
   p.after = data => data.sort((a, b) => b - a);

3. Add run function

   By default, this will run console.log on your final data

   p.run()

4. Run it!

   node your_script.js [data_file] [A or B]
