AoC2020 Solves - in Go! This year the solves will most likely be late!
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- (note, Day08 returns, at the moment,
(int64,int64), but that will change as soon as I care) - (note, Day21 has return type (int,string), given the nature of the puzzle)
- (note, Day08 returns, at the moment,
- Auxiliary packages for visualization purposes and to gather common functionalities (or those that I believe will become shared in the future)
- cmd directory:
- solver.go is the main entrance 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 (note: visualization is also possible, but enabled only for few days- nonexisting or broken for the others)
./solver --day XX
Example:
./solver --day 12

This will report the execution times of all the file reading and then of every single day (note: it automatically executes up to day25, even if only the stub is present, but the impact on execution time is negligible, less than 50ns for each 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)
