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
