eggnog πŸŽ„

Yet another Advent of Code CLI tool...

eggnog is a tool that allows you to download Advent of Code puzzle inputs, puzzle directions, and submit answers in the terminal.

It caches everything - even when a wrong answer is submitted.

Installation

eggnog works on MacOS and Linux.

Set the NOG_INSTALL_PATH environment variable.

# an installation option...
export NOG_INSTALL_PATH=/usr/local/bin

Then run

make install

Dependencies

It relies on the libcurl C library for http requests. Chances are it's already installed and you don't have to do anything. But if it doesn't work you may have to download it.

MacOS

brew install curl

Linux

sudo apt update
sudo apt-get install libcurl4-gnutls-dev
# or whatever packager you use

Run Tests

make tests

Usage

nog [--day=<day> --year=<year>] [OPTION] 

Day & year are required unless Advent is happening - latest puzzle will automatically be returned.

    -y <year>, --year=<year>
	The year of the puzzle you want to do.

    -d <day>, --day=<day>
	The day of the puzzle you want to do.

Options: If no options are supplied, input is assumed.

    -i, --input
	Download puzzle input.

    -p, --directions
	Get puzzle directions.

    -s, --submit=<answer>
	submit an answer to a puzzle. If no answer is supplied, read from
	stdin. Using '-s' automatically reads from stdin.

    -l <puzzle part>, --level=<puzzle part>
	Indicate whether submitting an answer to part 1 or part 2 of a puzzle.
	If left out, part 1 is assumed. **Required for submitting part 2 answers**.

Getting the puzzle input will print it to the terminal in the same way it would with curl. The purpose of that is because many advent of code solutions read from stdin rather than a hardcoded file name in the code.

Example usage

Get input for year 2020 day 1:

  • nog -y 2020 -d 1
  • or save to a file --> nog -y 2020 -d 1 > input.txt
  • or pipe it into your program --> nog -y 2020 -d 1 | ./myprogram

Submit an answer for year 2020 day 1 part 1:

  • nog -y 2020 -d 1 --submit=1234

Or read from stdin to provide your answer:

  • ./myprogram | nog -y 2020 -d 1 -s

Submit an answer for part 2:

  • nog -y 2020 -d 1 -l 2 -s

Cache

eggnog creates a local cache in the $HOME directory called .eggnog.

Puzzle directions, inputs, and all right and wrong answer submission attempts are saved. The cache is always checked before querying Advent of Code servers.

Unless the cache is deleted, any query to the servers happens only once.

To Do

  • WHen submitting an answer, if it's wrong, record the time. Require at least a minute to pass before sending another answer attempt.

Known Bugs

  • The bug that prevented from submitting answers to part 2 has been fixed βœ”οΈ
