runtime-dependency-manager 0.1.6

A simple Python module for managing dependencies at runtime

runtime_dependency_manager

runtime_dependency_manager is a simple Python module for managing dependencies at runtime. It is designed for small scripts that do not use a requirements.txt file. This module allows you to define and install dependencies directly within your script, making it ideal for quick scripts and prototypes.

Installation

You can install runtime_dependency_manager using pip:

pip install runtime_dependency_manager

Usage

Here's an example of how to use runtime_dependency_manager in your script:

try:
    from runtime_dependency_manager import RuntimeDependencyManager
except ImportError:
    print(f"Error: missing required package runtime_dependency_manager. Please install via:\n"
          f"\tpip install runtime_dependency_manager")
    sys.exit(1)

with RuntimeDependencyManager(install_if_missing=True) as mgr:
    mgr.index_url = "https://pypi.org/simple"

    with mgr.package('IPy', '>=1.1') as pkg:
        pkg.from_module('IPy').import_modules('IP', 'IPSet')

    with mgr.package('pymongo', '>=3.11.4, <4.0.0') as pkg:
        pkg.import_module('pymongo')
        pkg.from_module('bson').import_module('ObjectId')

    with mgr.package('paramiko', '==2.7.2') as pkg:
        pkg.from_module('paramiko').import_modules('SSHClient', 'AutoAddPolicy', 'SSHConfig', 'SSHException')

    with mgr.package('pyyaml', '>=5.4.1, <6.0.0', optional=True) as pkg:
        pkg.import_module('yaml')
