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
