getpack 0.2.0

Declarative external resources with implicit deployment

Declarative external resources any with implicit deployment

This package provide classes that allow to setup external resources (utilities, python packages etc.) that will be deployed as they are used. In most cases data should be on the web and it will be deployed and cached locally on only first usage.

There are several examples in test/ folder and getpack.library module already defined and useable. But main intention is to provide framework for declarative setup of any resource and work with it without care of deployment.

from getpack.resource import WebResource
class Example(WebResource):
    version = '0.1'
    archive_url = 'https://example.com/example-0.1.zip'

then it would be used:

import subprocess
subprocess.call(Example()().path / 'example.exe')

Second round braces required to actually make an effect from resource and first round braces used to initialize resource class, that would produce resource descriptions on the fly like follows:

Example(version='0.2', archive_url='https://Example.com/example-0.2.zip')

You may experiment with following working snippet and try to change PySide2 version:

python -c "import getpack.library;getpack.library.PySide2(version='5.14.1')(); import PySide2.QtWidgets; app=PySide2.QtWidgets.QApplication(); w=PySide2.QtWidgets.QPushButton(PySide2.__version__); w.clicked.connect(w.close); w.show(); app.exec_()"

TODO

• Utilize requirements.txt to reproduce both development and production environments.
