Setup Roc

A GitHub Action to download and setup the Roc compiler for Linux and macOS.

Usage

Add this step to your CI workflow:

Using Major Releases

- uses: roc-lang/setup-roc@39c354a6a838a0089eea9068a0414f49b62c5c08
  with:
    version: alpha4-rolling

Note: we recommend using this @commit-sha way to specify the version. This makes sure that the alpha4 release can not be altered if one of our github accounts is hacked.

Using Nightly Releases

- uses: roc-lang/setup-roc@39c354a6a838a0089eea9068a0414f49b62c5c08
  with:
    # Note: nightly hashes are not verified because they are updated regularly.
    version: nightly

Platform Support

This action supports the following platforms:

OS	Architecture	Status
Linux	x86_64	✅
Linux	arm64	✅
macOS	x86_64 (Intel)	✅
macOS	arm64 (Apple Silicon)	✅

What it does

1. Detects your operating system and architecture
2. Downloads the appropriate Roc compiler release for your platform
3. Verifies the SHA256 checksum to ensure file integrity (skipped for nightly releases)
4. Extracts the compiler
5. Adds the Roc executable to the PATH

Security

For major releases, the action verifies the SHA256 checksum of the downloaded file to ensure it hasn't been tampered with. If the checksum doesn't match, the action will fail.

For nightly releases, SHA256 verification is skipped since the files are updated regularly.
