Class DumbPreProcessor

PreProcessor --+
               |
              DumbPreProcessor

A preprocessor that ignores all #if/#elif/#else/#endif directives and just reports back all of the #include files (like the classic SCons scanner did).

This is functionally equivalent to using a regular expression to find all of the #include lines, only slower. It exists mainly as an example of how the main PreProcessor class can be sub-classed to tailor its behavior.

Method Summary

Inherited from PreProcessor
	`__call__(self, contents)` Pre-processes a file contents.
	`all_include(self, t)`
	`do_define(self, t)` Default handling of a #define line.
	`do_elif(self, t)` Default handling of a #elif line.
	`do_else(self, t)` Default handling of a #else line.
	`do_endif(self, t)` Default handling of a #endif line.
	`do_if(self, t)` Default handling of a #if line.
	`do_ifdef(self, t)` Default handling of a #ifdef line.
	`do_ifndef(self, t)` Default handling of a #ifndef line.
	`do_import(self, t)` Default handling of a #import line.
	`do_include(self, t)` Default handling of a #include line.
	`do_include_next(self, t)` Default handling of a #include line.
	`do_nothing(self, t)` Null method for when we explicitly want the action for a specific preprocessor directive to do nothing.
	`do_undef(self, t)` Default handling of a #undef line.
	`eval_expression(self, t)` Evaluates a C preprocessor expression.
	`find_include_file(self, t)` Finds the #include file for a given preprocessor tuple.
	`resolve_include(self, t)` Resolve a tuple-ized #include line.
	`restore(self)` Pops the previous dispatch table off the stack and makes it the current one.
	`save(self)` Pushes the current dispatch table on the stack and re-initializes the current dispatch table to the default.
	`start_handling_includes(self, t)` Causes the PreProcessor object to start processing #import, #include and #include_next lines.
	`stop_handling_includes(self, t)` Causes the PreProcessor object to stop processing #import, #include and #include_next lines.
	`tupleize(self, contents)` Turns the contents of a file into a list of easily-processed tuples describing the CPP lines in the file.
