Usage

Scaffold a day

# example: `cargo scaffold 1`
cargo scaffold <day>

# output:
# Created module "src/bin/01.rs"
# Created empty input file "src/inputs/01.txt"
# Created empty example file "src/examples/01.txt"
# ---
# 🎄 Type `cargo solve 01` to run your solution.

Individual solutions live in the ./src/bin/ directory as separate binaries.

Every solution has unit tests referencing its example file. Use these unit tests to develop and debug your solution against the example input. For some puzzles, it might be easier to forgo the example file and hardcode inputs into the tests.

When editing a solution, rust-analyzer will display buttons for running / debugging unit tests above the unit test blocks.

Download input for a day

Note
This command requires installing the aoc-cli crate.

# example: `cargo download 1`
cargo download <day>

# output:
# Downloading input with aoc-cli...
# Loaded session cookie from "/home/felix/.adventofcode.session".
# Downloading input for day 1, 2021...
# Saving puzzle input to "/tmp/tmp.MBdcAdL9Iw/input"...
# Done!
# ---
# 🎄 Successfully wrote input to "src/inputs/01.txt"!

To download inputs for previous years, append the --year/-y flag. (example: cargo download 1 --year 2020)

Puzzle inputs are not checked into git. Reasoning.

Run solutions for a day

# example: `cargo solve 01`
cargo solve <day>

# output:
#     Running `target/debug/01`
# 🎄 Part 1 🎄
#
# 6 (elapsed: 37.03µs)
#
# 🎄 Part 2 🎄
#
# 9 (elapsed: 33.18µs)

solve is an alias for cargo run --bin. To run an optimized version for benchmarking, append the --release flag.

Displayed timings show the raw execution time of your solution without overhead (e.g. file reads).

Run all solutions

cargo all

# output:
#     Running `target/release/advent_of_code`
# ----------
# | Day 01 |
# ----------
# 🎄 Part 1 🎄
#
# 0 (elapsed: 170.00µs)
#
# 🎄 Part 2 🎄
#
# 0 (elapsed: 30.00µs)
# <...other days...>
# Total: 0.20ms

all is an alias for cargo run. To run an optimized version for benchmarking, use the --release flag.

Total timing is computed from individual solution timings and excludes as much overhead as possible.

Run all solutions against the example input

cargo test

To run tests for a specific day, append --bin <day>, e.g. cargo test --bin 01. You can further scope it down to a specific part, e.g. cargo test --bin 01 part_one.

Format code

cargo fmt

Lint code

cargo clippy
