Processes the standard options the module pyquickhelper is able to process assuming the module which calls this function follows the same design as pyquickhelper, it will process the following options…


pyquickhelper.pycode.get_call_stack ()

Returns a string showing the call stack when this function is called.

unit tests

pyquickhelper.pycode.add_missing_development_version (names, root, hide = False)
