Howto Load Modules on Multiple Python Platforms

The YapyData.modules.loader module provides for the explicit import of modules as files. This covers all supported platforms and implementations, see Tested Platforms.

import_name, module_file_path = get_modulelocation(module_name)

load_module(module_name, module_file_path)

# imports and inserts into sys.modules

loaded_module.function1()

A more advanced search provides subpaths for a mor comprehensive search. The resulting import name could now be different from the provided input name, as the returned names are relative to the matched sys.path entry. The resulting import_name results in the the key entry within the sys.modules map.

basename = "/my/path/"
relpaths = ["sub/path0", "sub/path1"]

import_name, module_file_path = get_modulelocation(module_name, basename, relpaths)

loaded_module = load_module(import_name, module_file_path)

# imports and inserts into sys.modules

loaded_module.function1()

This module provides a special case for dynamic configuration and load of components. The feature is not covered by __future__ and future.utils, nor by the standard conversion tools such as py2to3. The software stack location is above the layers of __future__ and future.utils, but below the applications including infrastructure applications. Thus extends these.
