Package conary :: Package lib :: Module importer

Module importer

source code

Defines an on-demand importer that only actually loads modules when their attributes are accessed. NOTE: if the ondemand module is viewed using introspection, like dir(), isinstance, etc, it will appear as a ModuleProxy, not a module, and will not have the correct attributes. Barring introspection, however, the module will behave as normal.

Classes

OnDemandImporter
The on-demand importer imports a module proxy that inserts the desired module into the calling scope only when an attribute from the module is actually used.
