Advent of Code is an annual set of programming puzzles. Some might call it competitive programming. I mostly use it to learn new languages and improve my knowledge of the ones I already know.
This is my third year doing it. In 2019 I discovered it, did one day and the forgot about it. Every year since 2020 I've given it my best. 2020 was C. 2021 was learning Go. I wrote a lot of Go recently and looking back it was not really the best Go. This year I decied to do Go again but this year I hope for it to be idiomatic Go.
After 19 days working with Go got a bit tediosu and I spent more time doing the puzzles than I wanted to so I switched over to Python by the end.
- the project follows a very typical golang project structure
| directory | explanation |
|---|---|
| cmd | directory containing executables |
| internal | directory of project-only libraries |
| pkg | directory of libraries used by this project but that can imported elsewhere |
- an executable providing the solution for all days can be found in
cmd/solutions - inputs are on purpose not part of the repo as requested by Eric Wastl
- for this to work you have to add input.txt to every internal/day[0-9]+
cd cmd/solutions
go run . # To run a temporary executable
go build # To create an executable instead- the puzzle text makes it easy to create unit tests
- to run all of them:
go test ./...
