## What it is
nix-init is a Rust CLI tool that generates Nix package expressions from a source URL. It automates hash prefetching, dependency inference for Rust, Go, and Python projects, and license detection, with interactive prompts and a headless mode.

## Use cases
- generate a nix package derivation from a github url
- scaffold nixpkgs package expressions automatically
- prefetch cargo and go vendor hashes for nix builds
- infer dependencies for rust go or python projects in nix
- detect licenses when packaging software for nix
- create nix packages non-interactively in scripts

## When to choose
- you maintain or contribute to nixpkgs and want to speed up packaging
- you need a starting-point derivation for a new package and accept manual tweaks
- you want automated hash prefetching and license detection for nix packages

## When to avoid
- you don't use the nix package manager
- you need fully correct packages with zero manual review
- you need a general-purpose nix configuration generator rather than package derivations
