Software developers today spend much of their time editing programs that are missing pieces or that contain transient errors of various sorts. Conventional language definitions are silent about programs with "holes" like these. As a result, current development tools resort to ad hoc heuristics that fail to provide precise, accurate feedback about the program exactly when the developer needs it most. To tackle the problem of programs with holes directly, the project's novelties are to provide (1) a principled mathematical characterization of programs with holes, and (2) an open source development environment called Hazel designed from the ground up to support hole-driven development. The project's impacts are that (1) Hazel will initially target CS instructors, students, and domain scientists working in STEM fields, all of whom stand to benefit from more precise, live feedback throughout the development process; and (2) the theoretical foundations and prototype will inform the design of other software development environments both in research and industry, much like programming language theory has had a major impact on programming language and compiler design in the past decades.By applying the rigorous methodology of programming language theory to problems in programming environment design, the project will open up substantial new research directions for semanticists and tool designers alike. This project has several related specific aims that support the practice and (currently under-developed) theory of interactive software development. These aims are connected by a common technical device: Typed Holes. Specifically, the project will develop (1) a static semantics for typed holes, (2) a dynamic semantics for live programming with typed holes, (3) a semantics for structured edit actions that insert typed holes automatically, and (4) a mechanism that uses typed holes to support programming by direct manipulation of graphical user interfaces inside the program editor.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

如今，软件开发人员花费大量时间编辑缺失的程序或包含各种暂时性错误的程序。传统的语言定义对有这种“漏洞”的程序只字不提。因此，当前的开发工具求助于特定的启发式方法，无法在开发人员最需要的时候提供关于程序的精确、准确的反馈。为了直接解决有洞程序的问题，该项目的创新之处在于提供(1)有洞程序的原则性数学表征，(2)从头开始设计的名为Hazel的开源开发环境，以支持洞驱动开发。该项目的影响是：(1)Hazel最初的目标是在STEM领域工作的CS教师、学生和领域科学家，他们都将从整个开发过程中更精确的实时反馈中受益；(2)理论基础和原型将为研究和工业中的其他软件开发环境的设计提供信息，就像编程语言理论在过去几十年对编程语言和编译器设计产生了重大影响一样。通过将编程语言理论的严格方法论应用于编程环境设计中的问题，该项目将为语义学家和工具设计者开辟大量新的研究方向。这个项目有几个相关的具体目标，以支持交互软件开发的实践和(目前尚不发达的)理论。这些目标通过一种常见的技术设备联系在一起：打字孔。具体地说，该项目将开发(1)类型孔的静态语义学，(2)类型孔的动态语义学，(3)自动插入类型孔的结构化编辑动作的语义学，以及(4)通过直接操纵程序编辑器内的图形用户界面来使用类型孔来支持编程的机制。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
