Installation

Choose the installation method that works best for your workflow.

Package Managers

winget install --id rvben.rumdl --exact

brew install rumdl

cargo install rumdl

# Install globally
npm install -g rumdl

# Or as a project dev dependency
npm install --save-dev rumdl

# Or run without installing
npx rumdl check .

The npm package pulls in a prebuilt binary for your platform (Linux, macOS and Windows), so nothing is compiled on install. The rumdl command it installs is a small Node wrapper that runs that binary, and it needs Node.js 18 or newer.

pip install rumdl

# Install as a tool
uv tool install rumdl

# Or run without installing
uvx rumdl check .

# List available versions
mise ls-remote rumdl

# Install the latest version
mise install rumdl

# Use a specific version for the project
mise use rumdl@latest

nix-channel --update
nix-env --install --attr nixpkgs.rumdl

Or use flakes to run without installation:

nix run nixpkgs#rumdl -- --version

Platform-Specific

pacman -S rumdl

# Enable TUR repo first
pkg install tur-repo

# Then install rumdl
pkg install rumdl
