Anders Englöf Ytterström 4927b78e59 Solve 2025 day 2 pt 1-2 I tried to solve it without regexp at first, failed brutally. Cut the line count by 80% using a regexp instead. It was also funny to get all square roots.		2025-12-10 00:34:12 +01:00

Display all solved puzzles:

python aoc.py

To bootstrap a new puzzle (creates input/<day_no>.txt and output/day_<day_no>.py):

python aoc.py <day_no> new

Manually copy the puzzle input from https://adventofcode.com and paste it in input/<day_no>.txt to start coding.

wl-paste > input/<day_no>.txt

Solve separate puzzle (replace XX with the puzzle number):

python -m output.day_XX

Solve separate puzzle using stdin (replace XX with the puzzle number):

wl-paste | python -m output.day_XX
cat tmpfile | python -m output.day_XX

Execute separate puzzle on file save (replace XX with the puzzle number):

ls output/*.py | entr -c -s 'wlpaste | python -m output.day_XX'
ls output/*.py | entr -c -s 'cat tmpfile | python -m output.day_XX'
ls output/*.py | entr -c -r python -m output.day_XX

(requires entr and wl-paste, Mac users can instead use pbpaste. If you prefer X at Linux, use xclip -selection clipboard -o).
