| Research Abstract |
We designed and implemented a groupware for program comprehension. Our research results are :
1. Pierre ― a groupware system for program comprehension
Pierre offers various functionalities suitable for group program comprehension such as shared source code window and shared pointer. The system is coded in Java language, resulting high portability and efficiency.
2. Evaluation of Pierre
We read various programs (such as gnutella, IRC logger) using Pierre and evaluated the system through the analysis of activities and questionnaire survey.
3. Method for recording the result of comprehension
To record the result of comprehension, we found that chat conversation is suitable in its form (plain text) and its ease to type in.
4. Program comprehension through animation
We created an animation system for object oriented programs. The point is the way the animation is automatically simplified both in space (the number of elements of the program) and in time (detection and reduction of repeated behavior).
5. Unified explanatory description of program
We unified various explanatory description of programs such as comment, error message and debug message. They are described in a single statement in source program, and generated from the statement automatically.
