import hook, overwrite import?

[Kartic]

Hi Torsten,

If you want to use other methods to import (other than good ole file
system), yes, you can create an importer class and register it as an
importer module, that import will use to search and import.

For example, it is possible to use zip imports (this functionality is
already builtin) to import from a zip archive.
py>>> import zlib # required
py>>> import sys
py>>> sys.path.append('/location/to/zippedmodules.zip')
py>>> import testzip
py>>> testzip.__file__
'/location/to/zippedmodules.zip/testzip,py'

To generally do it, you have to:
1. Create a class that provides a load_module method that returns a
module type.
2.  Install your class as a hook using
sys.path_hooks.append(your_importer_class)

Please take a look at the imp module :
http://docs.python.org/lib/module-imp.html for a complete description
on accessing the import internals. There is also a simple example in
this section.

Is this is what you are looking for?

Thanks,
