The make_all_eiffel_stubs.py script

This takes only a little extra work; since the __dict__ symbol table contains entries for the module's classes as well, it's a relatively easy matter to shunt off code generation for class objects into functions from the make_eiffel_stub.py script. In fact, the only difference between the make_all_eiffel_stubs.py script and the previous two is that all you need to supply is a module name; the script will generate an eiffel class with the same name, and classes for all contained Python classes, prepending the name of the module. The command make_all_eiffel_stubs.py re, then, will generate not only the RE class, but also the RE__DUMMY class, the RE_MATCHOBJECT class, and the RE_REGEXOBJECT class.

Python modules can be nested, as in a_module.a_submodule.a_subsubmodule; to handle this, the make_all_eiffel_stubs script simply treats this as the name of a single module, replacing periods with underscores to generate an Eiffel-compatible name (for example, exporting the above module would generate the appallingly long-named A_MODULE_A_SUBMODULE_A_SUBSUBMODULE Eiffel class; if that module exported the class a_class, the generated Eiffel class name would be the even more unfortunate A_MODULE_A_SUBMODULE_A_SUBSUBMODULE_A_CLASS)

The addition of Makefile targets for the automatically-generated classes makes including this sort of automation in a makefile relatively easy:

#change this to show the automatically-created Eiffel files
GENERATED_EIFFEL_FILES = re.e re__dummy.e re_matchobject.e re_regexobject.e
#generated by the ePolyglot script "make_eiffel_stub.py"
$(GENERATED_EIFFEL_FILES) : 
	$(PYTHON) $(SCRIPTPATH)/make_all_eiffel_stubs.py re

...by appending GENERATED_EIFFEL_FILES to a list of "clean me" files, the build can be easily cleaned by the use of a dummy target.
