CodeMap: a Graphical Note-Taking Tool for Large-Scale Program Comprehension
Program comprehension is an important yet difficult activity in a software development process. One of the main causes of the difficulty is its cognitive overhead for maintaining the mental models, which consist of roles of program elements and relationships between them. Though researchers have been working on tools to help maintaining the mental models, existing tools have high adoption barrier and support only a few programming languages, which hinders wide-range of programmers from using the program comprehension tools. We propose CodeMap, a graphical note-taking tool for offloading the mental models onto a visual representation. We designed CodeMap by considering familiarity and availability for practitioners. Our tool allows programmers to extract interested information into a graphical note with a few keyboard/mouse operations, and support many programming languages by using the language server protocol.
