Convenience functions related to modules and importing.

Project description

Convenience functions related to modules and importing.

Latest release 20210123: module_attributes: skip values from other modules if we know the module (computed values like tuples have no module and still need to be returned).

Function direct_imports(src_filename, module_name=None)

Crudely parse src_filename for import statements. Return the set of directly imported module names.

If module_name is not None, resolve relative imports against it. Otherwise, relative import names are returned unresolved.

This is a very simple minded source parse.

Function import_module_from_file(module_name, source_file, sys_path=None)

Import a specific file as a module instance, return the module instance.

Parameters:

  • module_name: the name to assign to the module
  • source_file: the source file to load
  • sys_path: optional list of paths to set as sys.path for the duration of this import; the default is the current value of sys.path

Note that this is a "bare" import; the module instance is not inserted into sys.modules.

Warning: sys.path is modified for the duration of this function, which may affect multithreaded applications.

Function import_module_name(module_name, name, path=None, lock=None)

Import module_name and return the value of name within it.

Parameters:

  • module_name: the module name to import.
  • name: the name within the module whose value is returned; if name is None, return the module itself.
  • path: an array of paths to use as sys.path during the import.
  • lock: a lock to hold during the import (recommended).

Function module_attributes(M)

Generator yielding the names and values of attributes from a module which were defined in the module.

Function module_files(M)

Generator yielding .py pathnames involved in a module.

Function module_names(M)

Return a list of the names of attributes from a module which were defined in the module.
