Quickstart

This library has two main parts:

• Pip utils
• Dynamic library loading

Pip utils

This module provides some utilities for pip from Python.

Dynamic library loading

This library load, following some contrains, Python packages and load specific symbols from them. This is: functions, class definitions, variables, etc

The main idea of the project is to be able to create a plugin system which is easy to use and easy to maintain.

Install

> pip install dynamic-plugins

Dynamic module load usage

For this example we'll use the demo package demo_module that you can find in the demo_plugins folder.

First you need to install the demo package

> cd demo_plugins/demo_module
> pip install . -U

Load symbols

In this example we'll load the hello_world() function dynamically from the demo_module package.

from dynamic_plugins import get_extensions

def main():
    for package_name, package_content in get_extensions("demo-", sub_package="setup",symbols="hello_world").items():
        print(package_name)
        print(package_content["module_object"])
        
        for fn in package_content["symbols"]:
            print(fn())

if __name__ == '__main__':
    main()

Pip utils

List installed packages

from dynamic_plugins import list_installed_packages

def main():

    for package_name, package_version in list_installed_packages().items():
        print(f"{package_name} {package_version}")

if __name__ == '__main__':
    main()

Install a package from Pypi

from dynamic_plugins import install_library_from_pypi

def main():
    install_library_from_pypi("requests")

if __name__ == '__main__':
    main()

Install a package from local folder

from dynamic_plugins import install_library_from_path

def main():
    install_library_from_path("/path/to/package")

if __name__ == '__main__':
    main()
