aoc-cli

Advent of Code command-line tool 🎄

aoc-cli is a command-line tool for Advent of Code. It lets you read puzzle descriptions, download puzzle input, submit answers and check if they are correct, all from the comfort of your terminal. It is built using the aoc-client library.

Features ⭐️

Load Advent of Code session cookie from a file or environment variable.
Read puzzle description and optionally save it to a file in Markdown format.
Download puzzle input.
Submit your puzzle answer and check if it is correct.
Check your progress in your Advent of Code calendar (stars collected).
Show the state of private leaderboards.
Validate arguments (year, day, puzzle part) and check if puzzle is unlocked.
If year is not provided, default to the current or last Advent of Code event.
Infer puzzle day when possible (last unlocked puzzle for current and past events).

Installation options 🎅

Compile from source

Install a recent version of Rust using rustup or update it with:

# rustup update

aoc-cli relies on openssl-sys, which requires OpenSSL libraries and headers for compiling it. On Linux, you need to install a package with OpenSSL development headers such as libssl-dev or openssl-devel.

Install aoc-cli with cargo:

# cargo install aoc-cli

Homebrew

On macOS and Linux, use Homebrew:

# brew install scarvalhojr/tap/aoc-cli

Windows Package Manager

On Windows 10 and 11, use the Windows Package Manager command line tool:

# winget install aoc-cli

Download release artifacts

Executables for selected platforms are available in GitHub releases. Simply download and extract the file. An installer is also available for Windows.

The Linux package is statically-linked with OpenSSL and musl C library, and it should just work on most Linux distributions.

The macOS and Windows packages should automatically detect installed OpenSSL libraries. The MSVC Windows packages require the redistributable Visual C++ runtime library, whereas the MinGW packages require the Minimalist GNU for Windows runtime libraries.

Session cookie 🍪

Different Advent of Code users get different puzzle input. To download your input and submit your answer, you need an adventofcode.com session cookie. To obtain your session cookie, login to the Advent of Code website and inspect the session value of the cookie that gets stored in your browser - see instructions here.

The session cookie (a long hex string) must be provided in a single line (no line breaks) in one of the following ways (listed in order of precedence):

In a file specified via the --session-file command line option.
In an ADVENT_OF_CODE_SESSION environment variable.
In a file called .adventofcode.session (note the dot) in your home directory (/home/alice on Linux, C:\Users\Alice on Windows, /Users/Alice on macOS).
In a file called adventofcode.session (no dot) in your user's config directory (/home/alice/.config on Linux, C:\Users\Alice\AppData\Roaming on Windows, /Users/Alice/Library/Application Support on macOS).

Show private leaderboard

If you are a member of a private leaderboard, you can see how you are faring against your friends by passing the leaderboad number:

# aoc private-leaderboard 1234

[INFO  aoc] 🎄 aoc-cli - Advent of Code command-line tool
Private leaderboard of me & my friends for Advent of Code 2022.

Gold * indicates the user got both stars for that day,
silver * means just the first star, and a gray dot (.) means none.

                 1111111111222222
        1234567890123456789012345

 6)  20 *..................        Graciela Herzog
 7)   0 ...................        Thad Prohaska

Command abbreviations

Any non-ambiguous prefix of a command can be used instead of the full command name. For instance, instead of aoc read, you can type aoc r, aoc re or aoc rea. Similarly:

Instead of calendar, type c, ca, cal, etc.
Instead of download, type d, do, dow, down, etc.
Instead of private-leaderboard, type p, pr, pri etc.
Instead of submit, type s, su, sub, etc.

More examples

Download puzzle from a previous day (assumes the current year):

# aoc download --day 1

Download puzzle input from a previous year and save it to a file with a given name:

# aoc download --year 2015 --day 1 --input-only --input-file /home/user/aoc/2015/1/input

An attempt to download a puzzle that is still locked fails (puzzles unlock every day between 1st and 25th of December at midnight EST/UTC-5):

# aoc download --year 2030 --day 25

[INFO  aoc] 🎄 aoc-cli - Advent of Code command-line tool
[ERROR aoc] 🔔 Puzzle 25 of 2030 is still locked

Submit the answer to a previous year:

# aoc s 1 999 -y 2015 -d 1

Specify path to session cookie file:

# aoc download --session-file /tmp/.aoc.session
