This directory contains miscellaneous code that is imported from different parts of the codebase.

ast_helper.py contains

• generate_ast to read any file and generate an AST from it, this is called from __main__.py and stmt_visitor.py when importing a module.
• get_call_names used in vars_visitor.py when visiting a Subscript, and framework_helper.py on function decorators in is_flask_route_function
• get_call_names_as_string used in expr_visitor.py to create ret_function_name as RHS and yld_function_name as LHS, and in stmt_visitor.py when connecting a function to a loop.
• Arguments used in expr_visitor.py when processing the arguments of a user defined function and framework_adaptor.py to taint function definition arguments.

module_definitions.py contains classes created mostly in stmt_visitor.py

• `project_definitions`_ is a global dictionary modifed in the `append_if_local_or_in_imports`_ method of `ModuleDefinitions`_, read in framework_adaptor.py to obtain all function nodes.
• `ModuleDefinition`_ is created to keep track of parent definitions when visiting functions, classes and __init__.py files in stmt_visitor.py
• `LocalModuleDefinition`_ is created when visiting functions and classes in stmt_visitor.py
• `ModuleDefinitions`_ contains `append_if_local_or_in_imports`_ which is used in when adding a function or class to the module definitions in

node_types.py contains all the different node types created in expr_visitor.py and stmt_visitor.py

project_handler.py contains TODO
