nixpkgs 0.1.0

Abuses Nix philosophy, allowing me to do `from nixpkgs import scipy` anytime

# nixpkgs-python-importer

## What

An importlib hack that allows from nixpkgs import somepackage.

Examples:

import nixpkgs.scipy from nixpkgs import scipy from nixpkgs.matplotlib import pyplot as plt import nixpkgs.matplotlib.pyplot as plt

## Why

I am a researcher and I uses python and xonsh interactively a lot. While I appreciate the purity of Nix, sometimes I really want to violate it and pull in some dependency into my shell right now, without tearing my session down, editing and rebuilding an environment, and then recreating my session from history.

A convenient way of spawning a xonsh instant with an extra dependency soothes the nerves a bit, but doesn’t really free me from the recreation part.

I started writing a xonsh macro that ended up being a generic Python solution with a pleasingly nice syntax. I mean, from nixpkgs import scipy. Ain’t that nice?

## How
