A method for providing codebase modification assistance includes receiving training data including learning application code prior to modification and the same learning application code subsequent to modification, the modification being of a known type. Portions of the learning application code that have been changed by the modification are detected. One or more substrings are identified from names associated with the detected portions of the learning application code that have been changed. A target application code that is to be modified according to the known type of modification of the training data is received. The identified one or more substrings are searched for from names associated with portions of the received target application code. The portions of the target application code for which the one or more substrings have been found within associated names are displayed.
