The ihooks Module

The ihooks module, shown in Example 13-12, provides a framework for import replacements. The idea is to allow several alternate import mechanisms to coexist.

Example 13-12. Using the ihooks Module

File: ihooks-example-1.py import ihooks, imp, os def import_from(filename): "Import module from a named file" loader = ihooks.BasicModuleLoader() path, file = os.path.split(filename) name, ext = os.path.splitext(file) m = loader.find_module_in_dir(name, path) if not m: raise ImportError, name m = loader.load_module(name, m) return m colorsys = import_from("/python/lib/colorsys.py") print colorsys
