Work with Nix packages
======================
.. versionadded:: 2017.7.0
Does not require the machine to be Nixos, just have Nix installed and available
to use for the user running this command. Their profile must be located in
their home, under ``$HOME/.nix-profile/``, and the nix store, unless specially
set up, should be in ``/nix``. To easily use this with multiple users or a root
user, set up the `nix-daemon`_.
This module exposes most of the common nix operations. Currently not meant to be run as a ``pkg`` module, but explicitly as ``nix.*``.
For more information on nix, see the `nix documentation`_.

Lists installed packages. Due to how nix works, it defaults to just doing a ``nix-env -q``.
:param bool installed:
list only installed packages. This can be a very long list (12,000+ elements), so caution is advised.
Default: True

show the attributes of the packages when listing all packages.

:return: Packages installed or available, along with their attributes.

Erases a package from the current nix profile. Nix uninstalls work differently than other package managers, and the symlinks in the
profile are removed, while the actual package remains. There is also a ``nix.purge`` function, to clear the package cache of unused
packages.
