nix-tree
Interactively browse dependency graphs of Nix derivations.
Installation
nix-tree
is on nixpkgs
since 20.09
, so just use your preferred method for adding packages to your system, eg:
nix-env -i nix-tree
To run the current development version:
nix run github:utdemir/nix-tree
Usage
$ nix-tree --help
Usage: nix-tree [--version] [--derivation] [INSTALLABLE]

Available options:

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
