This is my workstation for Advent of Code.
TL;DR: Check out examples. That should almost clarify everything.
Note: If you are looking at a code with make_main! macro, that is deprecated. See below for How I used to use this.
For an actual competition, I can use the quick setup for a headstart. That requires some daily configuration though.
For casual use, I can just create a new binary in src/bin and use the aoc::main macro to ease the work of writing the main and test functions. Check out its documentation for more information.
After confirming the input and the test case, I can then run or test with Rust Analyzer's VSCode lens.
For further automation, I can configure some variables in config.json then use pull binary to directly pull the input from the website into input.txt. Note that the test input is not pulled.
Depending on your configuration, it can also automatically creates a new binary for part 1 of the day and open them with VSCode.1
For each question, I create a new binary in src/bin.
The main function I write is called compute. It takes a String as input and returns any type that implements Display.2
The make_main macro is then used to create the actual main function (and a test function, if prompted with an argument). They read input from input.txt and test.txt respectively.
I can then run or test with Rust Analyzer's VSCode lens.
