Install

Pick one or both — they’re independent, and the extension doesn’t require you to separately install the CLI.

VS Code / any VS Code-compatible editor (recommended for editing)

Install Drut for Cube Voyager from the VS Code Marketplace, or from Open VSX on VS Code-compatible editors that use it instead (Cursor, VSCodium, and similar).

Nothing else to install. On first activation, the extension resolves a working drut language server binary automatically: it checks PATH first, then its own persistent extension storage from a prior activation, then — if neither is present — downloads the correct binary for your platform from the latest GitHub Release and verifies it against its published SHA-256 checksum before trusting it. If every option is unavailable (offline, an unsupported platform, a failed download), the extension degrades to syntax-highlighting-only rather than failing outright, and tells you why once.

Once installed this way, a throttled (at most once per 24 hours), non-blocking background check offers a dismissible notification when a newer release is available — it never silently replaces a running binary.

Just the CLI (for scripting or CI)

cargo install drut-cli

Or build from source:

cargo build --release -p drut-cli
# binary at target/release/drut(.exe) -- put it on PATH

Confirm it’s working:

drut --help

Continue to Getting Started to run it against a real script.
