Wiz is an environment management framework which consists of a Python API and a command line tool. It can be used to run a command within a deterministic environment resolved from one or several package requests.

The packages are defined in package definitions which are stored in one or several registries.

The command line tool can be used as follows:

wiz use "app==2.*" my-plugin -- AppExe /path/to/script

Equivalent commands can be executed using the Python API:

import subprocess
import wiz

# Resolve context.
context = wiz.resolve_context(["app==2.*", "my-plugin"])

# Run command within environment.
command = context["command"]["AppExe"], environ=context["environ"])
