aoc-cli

Build and test Clippy and format Release crates.io

Advent of Code command-line tool.

Read Advent of Code puzzle descriptions, download puzzle input, submit answers and check if they are correct, all from the comfort of your terminal.

Features

Installation options

Compile from source

```

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.

```

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. Put the session number (a long hex string) in a file called .adventofcode.session in your home directory. This file should only contain your session number, in a single line.

Loaded session cookie from "/home/user/.adventofcode.session". Error: Puzzle 25 of 2030 is still locked. ```
