Abstract
A method of dynamically analyzing source code for generating usage hints while editing the source code is disclosed. A parse tree data structure is generated for each function called. The incoming and outgoing arguments in the parse tree are identified. A user calls the function by entering arguments as part of the function-call. The user's input arguments are associated with the corresponding argument in the parse tree. Relevant preconditions and post-conditions of the nodes surrounding the current location in the parse tree are analyzed to provide usage hints for the completion of the function call. In the case of a completed function call argument entered by the user, the type and number of arguments in the completed function call are compared to the required type and number of arguments of the function to validate the function call. Error messages are provided in the event of an invalid call.
