This project involves the development of practical programming tools in an integrated and open framework. Tools that support modern programming must deal with large systems, multiple programmers, multiple languages, a mixture of existing and new code, and multiple processes and threads. The work combines a variety of tools in an open, extensible, and powerful setting using control integration and a simple form of data integration based on fragments. Fragments are semantically significant portions of a program artifact: definitions or scopes in a source file, sections of documentation file, rules in a configuration description, etc. The approach to integration identifies such fragments and keeps references to them in a simple and small central database. This information is augmented with the data necessary to identify fragments using database queries, essentially usedef chains and small amounts of tool-specific information. In addition to fragment and control integration, the environment provids common facilities for defining and managing the files and contexts that make up a project, and a common editor for all software artifacts. The project manager serves as a front end for managing version control, configuration management, and multiple programmers. The common editor provides high quality typography along with support for hypertext links and graphics. On top of this environmental framework, this project investigates the development and utility of a variety of programming tools. The research extends visualization tools using a 3D visualization package developed under a previous NSF grant. A single front end would allow the programmer to specify both what information (from a variety of sources) should be visualized and how it should be presented for each particular application. Experiments measure the ffectiveness of visualizations for understanding both the static structure and the dynamic behavior of complex systems. A third set of tools involves editing. The project would extend an existing editor to allow programmers to view the system as a single electronic document with dynamic and static links connecting the various software artifacts. These links would be defined either by built-in queries (e.g. go to the definition of a name), by user-defined queries, or by static links.

该项目涉及在集成和开放的框架中开发实用的编程工具。支持现代编程的工具必须处理大型系统、多个程序员、多种语言、现有代码和新代码的混合以及多个进程和线程。这项工作使用控制集成和基于片段的简单形式的数据集成，将各种工具组合在开放、可扩展和强大的设置中。 片段是程序工件的语义上重要的部分：源文件中的定义或范围、文档文件的部分、配置描述中的规则等。集成方法识别此类片段并将对它们的引用保留在简单且小型的中央数据库中。 使用数据库查询识别片段所需的数据（本质上是 usedef 链和少量特定于工具的信息）增强了该信息。除了片段和控制集成之外，该环境还提供用于定义和管理构成项目的文件和上下文的通用设施，以及用于所有软件工件的通用编辑器。 项目管理器充当管理版本控制、配置管理和多个程序员的前端。 通用编辑器提供高质量的排版以及对超文本链接和图形的支持。 在此环境框架之上，该项目研究了各种编程工具的开发和实用性。 该研究使用先前 NSF 拨款开发的 3D 可视化包扩展了可视化工具。 单个前端将允许程序员指定应该可视化哪些信息（来自各种来源）以及如何为每个特定应用程序呈现这些信息。实验衡量可视化对于理解复杂系统的静态结构和动态行为的有效性。 第三组工具涉及编辑。 该项目将扩展现有的编辑器，以允许程序员将系统视为单个电子文档，并具有连接各种软件工件的动态和静态链接。 这些链接可以通过内置查询（例如，转到名称的定义）、用户定义的查询或静态链接来定义。
