Today's integrated development environments (IDEs) are hampered by their dependence on files and file-based editing. We propose a novel user interface that is based on collections of lightweight editable fragments, called bubbles, which when grouped together form concurrently visible working sets. In this paper we describe the design of a prototype IDE user(More)
We propose the metaphor of rubber sheet stretching for viewing large and complex layouts within small display areas. Imagine the original 2D layout on a rubber sheet. Users can select and enlarge diierent areas of the sheet by holding and stretching it with a set of special tools called handles. As the user stretches an area, a greater level of detail is(More)
Our goal is to use the vast repositories of available open source code to generate specific functions or classes that meet a user's specifications. The key words here are specifications and generate. We let users specify what they are looking for as precisely as possible using keywords, class or method signatures, test cases, contracts, and security(More)
Dynamic software visualization is supposed to provide programmers with insights as to what the program is doing. Most current dynamic visualizations either use program traces to show information about prior runs, slow the program down substantially, show only minimal information, or force the programmer to indicate when to turn visualizations on or off. We(More)
Developers spend significant time reading and navigating code fragments spread across multiple locations. The file-based nature of contemporary IDEs makes it prohibitively difficult to create and maintain a simultaneous view of such fragments. We propose a novel user interface metaphor for code understanding based on collections of lightweight, editable(More)
