pypackages 0.1a3

Script specific packages

pypackages

Script specific packages similar to PEP 582 using a __pypackages__ directory. The __pypackages__ directory must be in the same directory as the script being executed.

Intent

Simplify the distribution of python scripts with dependencies. No need to use virtual environments or explicitly install dependencies using pip.

(Optional) Automatic requirements install

Place requirements.txt in the __pypackages__ folder to install or upgrade on startup using pip.

This saves the need for distributing python version specific packages explicitly.

Requirements

pip must already exist in the python environment if requirements.txt is used.

Installation

Install pypackages directly into your project as follows:

pip install --target . --upgrade pypackages

Structure of pypackages

myapp.py
__pypackages__/
    requirements.txt  (optional)
    bin/
    lib/
        python3.11/
            site-packages/

Structure of deployment

myapp.py
pypackages/
    __init__.py
__pypackages__/
    requirements.txt

Example (requirements.txt)

sanic==22.12.0

Example (myapp.py)

#!/usr/bin/python
import pypackages
from sanic import Sanic
from sanic.response import text

app = Sanic('myapp')


@app.route('/')
async def hello(request):
    return text('Hello, world')


if __name__ == '__main__':
    app.run(port=9999)
