Abstract
A method of dynamically analyzing source code to generate usage hints for a user performing program editing is disclosed. The functions in a collection of source code being edited by a user are processed so as to generate a parse tree data structure for each function called. The incoming and outgoing arguments in the parse tree are identified. Subsequently, a user editing code calls the function and either completely or incompletely enters the arguments as part of the function called. Input arguments are identified and associated with the corresponding argument in the parse tree for the function. Relevant preconditions and post-conditions of the surrounding nodes corresponding to the current location are analyzed. Usage hints are provided for the completion of the function call. Arguments for a completed function call argument entered by the user are validated. Error messages are delivered in the event of an invalid call.
