A framework to design sound, reproducible and scalable mining repositories studies on GitHub.

### Scyros is...

- 🧪 **Reproducibility-first**: declarative configuration and deterministic execution to enable repeatable experiments.
- 📈 **Scalable**: designed for large-scale repository mining studies on GitHub.
- 🧱 **Soundness-focused**: encourages transparent, bias-aware, and methodologically explicit study design.
- ⚙️ **Modular**: independent, reusable modules that can be composed into custom data-processing pipelines.

## Installation

### Prebuilt binaries

Prebuilt binaries for macOS, Linux, and Windows are available on the project's [GitHub Releases page](https://github.com/fxpl/scyros/releases), along with installer scripts.

### Build from source

If you prefer to build Scyros yourself, install Rust (version 1.94 or newer) by following the instructions on the [official website](https://rust-lang.org/tools/install/).

Then clone the repository and build:
```bash
git clone git@github.com:fxpl/scyros.git
cd scyros
cargo build --release
```

The binary is produced at `target/release/scyros`. You can optionally move it to a directory in your PATH for easier access.

## Usage

To discover available commands and modules:

```bash
scyros --help
```

Each module provides its own usage documentation. For example, to inspect the module used to sample random repositories from GitHub:

```bash
scyros ids --help
```

## Authentication and Rate Limits

Some modules interact with the GitHub API and require personal access tokens (PATs). Tokens can be created by following GitHub’s documentation: [https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token).

⚠️ Never commit or share your tokens publicly.

Tokens must be provided as a CSV file passed via a command-line argument. The file must contain a single column named token, with one token per line:
```csv
    token
    fa56454....
    hj73647.... 
```

GitHub enforces API rate limits. Using multiple tokens from the same account does not increase these limits. Users are expected to comply with GitHub’s API terms and rate-limit policies:
- [Rate limits for the REST API](https://docs.github.com/en/rest/using-the-rest-api/rate-limits-for-the-rest-api?apiVersion=2022-11-28)
- [Terms of Service](https://docs.github.com/en/site-policy/github-terms/github-terms-of-service)
