Advent of code 2021

cf. https://adventofcode.com/2021/

Invocation

Invoke advent.py with the advent day:

# pyenv local 3.9.6

./advent.py 1
# or
./advent.py 9 --toy --verbose
# or
./advent.py --all

Tests

Tests should be run with pytest, and verifies toy solutions and real solutions. Some days' solutions have one-off sanity check tests that I used for making sure helpers worked as expected, but do not need to be run as part of the test suite.

pytest .
pyright .

Scaffolding a new day's solution

Use scaffold.sh to create a blank solution template + input file

./scaffold.sh 13
# creates
#	days/day13.py
#	input/13.txt

After creating these, one must still import that day's solution in advent.py:

from days.day13 import day_13

These imports are used to autodetect solutions. I want to make this more automated with importlib, but haven't bothered yet with the extra complexity of figuring that out.

One must also add a line of expected test values in test_advents.py:

TOY_EXPECTED = {
    # ....
    13: [17, None],  
    # ^^^ note no toy value for part 2 until I solve part 1
}


EXPECTED = {
    # ....
    13: [None, None],  
    # ^^^ fix these once we succeed at a solution
}
