Advent of Code 2020 via F#

This repo contains my attempt at Advent of Code 2020 (https://adventofcode.com/2020).

Running it

Run with the dotnet CLI inside the project you wish to run. For day 1, you would run:

cd src/Day01

# To run it on "input.txt" in current working directory
dotnet run

# To run it on some other file, example:
dotnet run -- sample.txt

There is a template project, named DayXX. To make a new one, you may first set the following environment variable:

# If using bash, zsh, sh, dash, ash...
AOC_DAY=03

# If using fish
set AOC_DAY 03

# If using PowerShell
$AOC_DAY='03'

Then run the following commands:

cp -r "src/DayXX" "src/Day$AOC_DAY"
mv "src/Day$AOC_DAY/DayXX.fsproj" "src/Day$AOC_DAY/Day$AOC_DAY.fsproj"
dotnet sln add "src/Day$AOC_DAY"
