Consistent use of this module will make it possible to change the different mechanisms involved in loading modules independently. While the built-in module imp exports interfaces to the built-in module searching and loading algorithm, and it is possible to replace the built-in function __import__ in order to change the semantics of the import statement, until now it has been difficult to combine the effect of different __import__ hacks, like loading modules from URLs by rimport.py, or restricted execution by rexec.py. This module defines three new concepts: 1) A "file system hooks" class provides an interface to a filesystem. One hooks class is defined (Hooks), which uses the interface provided by standard modules os and os.path. It should be used as the base class for other hooks classes. 2) A "module loader" class provides an interface to search for a module in a search path and to load it. It defines a method which searches for a module in a single directory; by overriding this method one can redefine the details of the search. If the directory is None, built-in and frozen modules are searched instead. Two module loader class are defined, both implementing the search strategy used by the built-in __import__ function: ModuleLoader uses the imp module's find_module interface, while HookableModuleLoader uses a file system hooks class to interact with the file system. Both use the imp module's load_* interfaces to actually load the module. 3) A "module importer" class provides an interface to import a module, as well as interfaces to reload and unload a module. It also provides interfaces to install and uninstall itself instead of the default __import__ and reload (and unload) functions. One module importer class is defined (ModuleImporter), which uses a module loader instance passed in (by default HookableModuleLoader is instantiated). The classes defined here should be used as base classes for extended functionality along those lines. If a module importer class supports dotted names, its import_module() must return a different value depending on whether it is called on behalf of a "from ... import ..." statement or not. (This is caused by the way the __import__ hook is used by the Python interpreter.) It would also do wise to install a different version of reload().

This provides the same functionality as built-in import. It doesn't deal with checking sys.modules -- all it provides is find_module() and a load_module(), as well as find_module_in_dir() which searches just one directory, and can be overridden by a derived class to change the module search algorithm when the basic dependency on sys.path is unchanged. The interface is a little more convenient than imp's: find_module(name, [path]) returns None or 'stuff', and load_module(name, stuff) loads the module. c C sZ | d j o d g | i } n x/ | D]' } | i | | } | o | Sq+ q+ Wd S( N( t patht NoneR t default_patht dirt find_module_in_dirt namet stuff( R R R R R ( ( R t find_modulep s c C s t i S( N( t sysR ( R ( ( R R x s c C sS | d j o | i | Sn2 y t i | | g SWn t j o d Sn Xd S( N( R R R t find_builtin_moduleR t impR t ImportError( R R R ( ( R R { s c C sX t i | o d d d d t f f Sn t i | o d d d d t f f Sn d S( Nt ( R t is_builtinR R t BUILTIN_MODULEt is_frozent FROZEN_MODULE( R R ( ( R R s c C sF | \ } } } z t i | | | | SWd | o | i n Xd S( N( R t filet filenamet infoR t load_moduleR t close( R R R R) R( R' ( ( R R* s ( R R t __doc__R R R R R R* ( ( ( R R _ s c B sψ t Z d Z d Z d Z d Z d Z d Z d Z d Z e d Z e d Z e d Z e d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z d Z e Z d Z e i Z RS( sί Hooks into the filesystem and interpreter. By deriving a subclass you can redefine your filesystem interface, e.g. to merge it with the URL space.
