don't look in `src/bin/day_*.rs` if you don't want spoilers.
|
||
|
|
|
||
|
|
yes some of this setup is needlessly overengineered
|
||
|
|
|
||
|
|
## magic rust macros (tm)
|
||
|
|
|
||
|
|
yes
|
||
|
|
|
||
|
|
i thought teehee i could make a proc macro for this
|
||
|
|
|
||
|
|
## using this
|
||
|
|
|
||
|
|
just don't
|
||
|
|
|
||
|
|
### ok alright
|
||
|
|
|
||
|
|
Make a solution for a day:
|
||
|
|
|
||
|
|
```rust
|
||
|
|
// Some useful things, including macros + color_eyre
|
||
|
|
use aoc_2022::prelude::*;
|
||
|
|
|
||
|
|
type Input = String; // some mildly useful structure for the input data
|
||
|
|
|
||
|
|
fn parse(s: &str) -> Result<Input> {
|
||
|
|
// implement whatever scary string manipulation you like
|
||
|
|
Ok(s.to_owned())
|
||
|
|
}
|
||
|
|
|
||
|
|
// heres some macro magic ✨
|
||
|
|
#[aoc(
|
||
|
|
day = 100, // used to fetch the challenge stuff from AOC directly
|
||
|
|
parse = parse, // so I can reuse parsers if needed
|
||
|
|
test_cases = ["day_100.txt"] // loaded from `test_cases/`
|
||
|
|
)]
|
||
|
|
fn day_100(mut input: Input) -> Result<()> {
|
||
|
|
// do something remotely awful to solve the challenge
|
||
|
|
|
||
|
|
// probably should println!() the results or something
|
||
|
|
|
||
|
|
Ok(())
|
||
|
|
}
|
||
|
|
|
||
|
|
// macro: a wild main function appears!
|
||
|
|
```
|
||
|
|
|
||
|
|
### auto-fetching
|
||
|
|
|
||
|
|
steal your session cookie from the browser devtools
|
||
|
|
|
||
|
|
make `.env` and add `AOC_SESSION=<your massive long session token>`
|
||
|
|
|
||
|
|
maybe use direnv to make it easier to load the `.env` file? (and the nix flake (yes theres one of those too uwu))
