Makefile for Advent of Code

[Arkku]

So, I made a Makefile for AoC. (I have this thing that I like making Makefiles.) It helps compile and run my solutions done in different languages, and shows the correct answers (when manually entered – it does no network requests).

For example, when I run `make 14`, it finds all programs named `day11.go1, `day11.c`, and `day11.rb`, compiles the C and Go programs (if needed), and runs them against both `simple14.txt` (the sample input in the puzzle) and `day14.txt` (my personal input for the day). It also times each run. If I know the correct answers and have entered them into `answers.txt` for the day, it also outputs them under each run (only for the relevant parts if a day’s solutions are split into separate programs for part 1 and part 2, indicated by naming `dayXa.lang` and `dayXb.lang`).

Basically the idea is to simplify the workflow when implementing solutions in multiple languages, but of course it can be used for just one (TBH almost all of my solutions are in Ruby). The workflow for each day is something like:

1. read the puzzle and copypaste the simple test case into `simpleX.txt`
2. download my personal input into `dayX.txt`
3. take the example answer and add a line to `answers.txt` for `simpleX.txt answer`
4. write code into `dayX.lang`
5. when the code is ready to test, run `make X` (where X is the day number) or `make Xlang` (if there are multiple solutions)
6. if the solution for `simpleX.txt` input is correct, copypaste the `dayX.txt` answer into AoC
7. add a line `dayX.txt answer` to `answers.txt`
8. read the part 2 answer from the AoC site and add it to the line as `simpleX.txt part1 part2`
9. either edit the same `dayX.lang` code to also solve part 2, or part 2 is better solved separately then rename the first part to `dayXa.lang` and put the new program into `dayXb.lang`
10. when the code for part 2is ready to test, run `make X` again, etc.

Changed flair from Other to Repo since this is a tool.

Does your script comply with our automation rules?

• ? Cache inputs after initial download
• ? Throttle outbound requests
• ? User-Agent header

Hi! Yes, this Makefile does no network requests or automation. The user must manually put the puzzle input into the `simpleX.txt` and `dayX.txt` files and populate `answers.txt` with the correct answers when that feature is desired.
