nix-init

Generate Nix packages from URLs

Note: It is likely that the generated package will not work without some tweaks, also remember to double check the license and description even if it does work

• Hash prefetching powered by nurl with support for cargoHash and vendorHash
• Dependency inference for Rust and Python projects
• Interactive prompts with fuzzy tab completions
• License detection

Installation

The latest release of nix-init is packaged in nixpkgs and kept up to date on the unstable branches

If you want to use a more recent snapshot of nix-init, it is also available as a flake. The following command is equivalent to running nix-init --help:

nix run github:nix-community/nix-init -- --help

or if you don't have flakes enabled:

nix run --extra-experimental-features "flakes nix-command" github:nix-community/nix-init -- --help
