Abstract

We argue that a modern programming language such as Scala offers a level of succinctness, which makes it suitable for program and systems specification as well as for high-level programming. We illustrate this by comparing the language with the Vdm++ specification language. The comparison also identifies areas where Scala perhaps could be improved, inspired by Vdm++. We furthermore illustrate Scala's potential as a specification language by augmenting it with a combination of parameterized state machines and temporal logic, defined as a library, thereby forming an expressive but simple runtime verification framework.
缩小规范和编程之间的差距:VDM++和Scala
我们认为,像Scala这样的现代编程语言提供了一定程度的简洁性,这使得它适合于程序和系统规范以及高级编程。我们通过比较该语言与Vdm++规范语言来说明这一点。这一对比还指出了受Vdm++的启发,Scala可能需要改进的地方。我们进一步说明了Scala作为一种规范语言的潜力,通过将参数化状态机和时态逻辑(定义为库)的组合对其进行扩展,从而形成一个富有表现力但简单的运行时验证框架。
