Advent of Code

Running days

To run a day (c++ only) with main input, use:

a="src/main/_2020/day01.bin"
make "$a" && time ./$a < $(echo "${a%*.*}_00.in" | sed 's/main/test/')

Some java files are hardcoded to run with the main input already Otherwise, anything that expects input to come from stdin, can be done similarly

Directory sturcture

adventofcode/Makefile (file)
adventofcode/src/{main,test}/{_year,template,util}

The underscore allows the year to be used as a code organiser (e.g. valid Java package identifier)

adventofcode/src/main

_year

contains solutions for a given day xx in the form of dayxx.ext

template

contains templates for java and c++ solutions

quite sparse right now

util

contains helper functions/classes/etc. to be used by the daily solutions for all languages

adventofcode/src/test

contains test cases for each of the corresponding solutions, formatted as such:

	dayxx_nn.in

where xx is the day, and nn is the test case for that day

Should use *_00.txt for the actual input/solution set and *_0[1-9].in for smaller test inputs

Later, I'll move all my unit testing into here under TestDayXX.java (probably c++ too, but not sure how yet)

Commit messages

• refer to the days with padded numbers (e.g. day01, day10)

• refer to the years without underscores (e.g. 2017, 2018)

• refer to year/day combinations as year/day (e.g. 2018/day01)

• where possible, commit with the year/day combination to be as explicit as possible

  • this avoids unwanted confusion with mixing up the years
