Abstract

Aspects of the subject matter described herein relate to creating and using deltas to modify existing computer code. In aspects, computer code may be translated into a higher level language to make it easier for a software developer to modify the computer code. The translated computer code may be presented by an editing tool that presents a user interface that allows changes to be made to the translated computer code. A delta engine may then determine a delta that indicates the changes to perform on the existing computer code to create computer code that would result from compiling the translated computer code as changed via the editing tool. Later, this delta may be used to change the existing computer code after it has been loaded to add or change debugging hooks or other features of the computer code.
