rqp-plugin-nix

ReqPack Lua plugin for native nix installations.

Plugin wraps modern nix profile workflow for install, remove, update, and list operations. It uses nix search for search, info, outdated, and package resolution.

Behavior

• bootstraps a single-user Nix install with the official installer when no nix binary is available
• passes --extra-experimental-features 'nix-command flakes' on every Nix CLI call so profile and search work without host config changes
• maps simple names like hello to nixpkgs#hello
• keeps explicit installables unchanged, for example nixpkgs#hello, github:owner/repo#pkg, .#pkg, /path/to/flake
• uses nix profile list --json for installed-state checks and listing
• reports outdated mutable nixpkgs installs by comparing installed profile version with current nix search result

Supported ReqPack Paths

• install
• installLocal
• remove
• update
• list
• search
• info
• resolvePackage

Testing

Run hermetic plugin tests from plugin root:

rqp test-plugin --plugin ./run.lua --preset core

Notes

• installLocal() treats local path as native Nix installable and forwards it to nix profile install
• package-specific updates rely on Nix profile entry names and only run when newer version is detected
• exact package pinning through separate ReqPack version field is not supported by nix profile; use explicit Nix installables when needed
