## Setup
1. Install [Rust](https://www.rust-lang.org/tools/install)
2. Open with [VS Code](https://code.visualstudio.com/)
3. Install the suggested extensions when prompted (Recommended)
4. Install the required crates
```sh
cargo build
```
> Select `Current Rust Cargo` launch option. **F5** runs the cargo you're
> focusing in debug mode. Set Rust to default to `nightly`
```sh
rustup default nightly
```
### Debug
> Since CodeLLDB does not play well with cargo workspaces use the `Debug` or
> `Run` codelense from the `rust-analyser` VS Code extension
### Running individual days
```sh
cargo run -p aoc201601
```
### Testing
Run in the cargo you'd like to test
```sh
cargo test
```
Or in the workspace cargo if you'd like to run all tests
```sh
cargo test --all
```
### Benchmarking
Run a specific days benchmark
```sh
cargo bench -p aoc201501
```
Or in the workspace cargo if you'd like to run all benchmarks (Takes a while!)
```sh
cargo bench --all
```
## Scaffolding
```sh
cargo run -p scaffold 2016 01
```
## Requirements
- OpenSSL dev libraries
To install on Ubuntu:
```sh
sudo apt install libssl-dev pkg-config
```
## Notes
Rustfmt's config file is symlinked to the repository root because the
[rust-analyser extension can't pick it up otherwise.](https://github.com/rust-analyzer/rust-analyzer/issues/7227)
The github action `actions-rs/cargo@v1`
[cannot be run in a subdirectory either](https://github.com/actions-rs/cargo/issues/86)
so `--manifest-path` has to be set for each step.
The github action `actions-rs/audit-check@v1` is disabled because it too cannot
be run in a subdirectory but additional argument cannot be passed
[until this pr is merged](https://github.com/actions-rs/audit-check/pull/133).
Until that, this step is done manually.
