Simple bootstraping of python scripts

This is an early prototype of a simple bootstrapping system for python. By importing scriptstrap into a python script, a virtual environment ("venv") will be automatically created, dependencies installed (using pip) and the script will finally be re-launched inside the venv. This simplifies distribution of small utility scripts, as package dependencies are automatically manged by just running the script.

The intended use case for scriptstrap is single-file utility scripts only!

Features

• Automatic creation of virtual environment for each script
• Dependencies are installed and imported automatically
• Simplified script distribution
• No additional dependencies other than python and virtualenv

Requirements

• Python 2.7 or later
• virtualenv

Getting started

You must do a global install of scriptstrap or run it from another venv. Recommended installation is:

$ pip install scriptstrap

Example

Simple script that downloads the Google main page and prints it:

import scriptstrap

scriptstrap.python3('requests')

print(requests.get('http://google.com').content)

Running the script, assuming the script is called requests.py, will create a new venv in a directory called requests.venv3 next to the script. If the script is launched again, the same venv will be re-used.
