Abuses Nix philosophy, allowing me to do `from nixpkgs import scipy` anytime
Project description
# 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 use `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` instance 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
`importlib` magic
## Try
The quickest way would be
```
nix-shell -p 'python3.withPackages(ps: with ps; [ (python3.pkgs.buildPythonPackage rec { pname = "nixpkgs"; version="0.1.0"; src = python3.pkgs.fetchPypi { inherit pname version; sha256 = "108f7h15d7cbzz6kvf15m93lzf18wgxrzb17p5vk184n3ds42lvy"; }; }) ])' --run python
```
then try `from nixpkgs import ` something.
