Installation

Nautilus is a Reef package. Install Chelis from the official releases, using the compiler version required by the Nautilus release.

Install the Nautilus release into your local Reef registry. The release is public, so no token is needed:

chelis reef install --from-github Chelis-Lang/nautilus@v0.7.58

The command prints Installed nautilus 0.7.58 and stores the package under ~/.chelis/reef/packages/nautilus/0.7.58/.

Add Nautilus to your project's [dependencies] table in reef.toml:

[dependencies]
nautilus = { version = "0.7.58" }

Set your project's compiler pin to the exact compiler version required by the installed Nautilus package. From the project directory, run:

chelis reef build

The build resolves Nautilus from the local registry, writes reef.lock with the pinned versions and hashes, and prints Built <project> <version>. If Nautilus is not in the local registry, reef build can discover its public GitHub release after you set GITHUB_TOKEN or authenticate with gh auth login. On another machine, chelis reef setup reinstalls every dependency recorded in reef.lock.

Continue with Your first Nautilus program to evaluate a calculation. The Reef and packages guide covers dependency setup and compiler compatibility.
