Glossary

  • NAR Size: Size of the store path itself.
  • Closure size: Total size of the store path and all its transitive dependencies.
  • Added size: Size of the store path, and all its unique transitive dependencies. In other words, the cost of having that store path on top of all other paths. See issue #14 for a better explanation.

Tips

nix-build prints built paths to stdout, which can be piped conveniently with | xargs -o nix-tree. Examples:

# Output of a local derivation
nix-build . --no-out-link | xargs -o nix-tree

# Build time dependencies (passing a `.drv` path)
nix-instantiate --no-out-link | xargs -o nix-tree

# Dependencies from shell.nix
nix-build shell.nix -A inputDerivation | xargs -o nix-tree

# All outputs of a derivation in nixpkgs:
nix-build '<nixpkgs>' -A openssl.all --no-out-link | xargs -o nix-tree

Hacking

All contributions, issues and feature requests are welcome.

To hack on it, simply run nix-shell (or nix develop) and use cabal as usual.
