AoC2021 Solves - in Go!
The repository is structured as follwos:
- pkg directory:
- One package, named Day##, for the ## day of the month (e.g. Day01)
- Every package presents the same interface: one exported method
func Solve(input string) (int,int)which provides the answers for part 1 and part 2
- cmd directory:
- solver.go is the main entry point, it can be compiled into an executable that can either execute a specific day, or present the execution time of all days
- solver_test.go provides unit testing to verify that refactoring doesn't break old days
- NOTE: these are NOT unit tests on the examples provided in the puzzle. I fill them after solving the day to make sure I do not break old days when refactoring.
To execute unit tests, simply run go test ./... from the root directory (note: most packages don't have tests so far, so you might just care about running it inside cmd)
To execute the solver, go into the cmd directory and build the executable: go build solver.go. This will create an executable called solver, which can be either used to solve a single day or to time the execution times of all days
./solver --day XX
Example:
./solver --day 12

This will report the execution times of all the file reading and then of every single day
The program expects input files to be in an /inputs folder, each day named as X.txt (e.g. 1.txt, 15.txt, please note the absence of a leading zero here)
