aoc-nim

Advent of Code in Nim

My goal is to build self-contained solutions (no external libs) using clean and concise code.

Running scripts

All code compiles with the current (>= v1.6) Nim compiler, for example: nim c -r d01.

To run the solutions:

• feed the input to stdin: dXX < input/dXX.txt, or use the helper script aoc.
• to use data from clipboard: pbpaste --lf | dXX

Helper script to download puzzles/input data and run/test solutions:

bin/aoc command [day] [year]

Available commands (for the given day/year):

• p, puzzle - download the puzzle description
• i, input - download the input data file
• t, template - copy the template as placeholder
• c, compile - compile the script
• e, example - run the script with example input (from clipboard)
• r, run - run the script
• x, check - run the script, check is answers match saved data
• w, write - write answers to the file

Day and year are optional, default to current. Download commands need the session.txt file to be present.

Structure

bin/aoc is a helper tool to download puzzles & inputs, prepare template. AoC session cookie is expected to be saved in the file session.txt (just the value). Puzzle parsing depends on the html2md tool.

Sub-folders for each year contain:

• puzzles - description of AoC puzzles
• inputs - (my personal) input data
• answers - (my personal) solution answers
• solutions code
