摘要

大多数解析器工具都集中于具体的语法和语法定义。本文描述了一个使用元模型规范代替语法作为语言定义基础的语言定义工具。受类似的Java工具YAJCo的启发,元模型是使用通常的面向对象技术(Python编程语言中的类)定义的,解析过程的结果是一个对象图。在一个简单的命令式编程语言的案例研究中演示了该工具。我们解释了我们的设计决策,并演示了动态语言(如Python)对该任务的适用性。

Metamodel-based Language Definition with Python
Most of the parser tools are concentrated on concrete syntax and grammar definition. This paper describes a language definition tool that uses a metamodel specification instead of grammar as the basis of the language definition. Inspired by a similar Java tool known as YAJCo, the metamodel is defined using usual object-oriented techniques—as classes in the Python programming language, and the result of the parsing process is a graph of objects. The tool is demonstrated in a case study of a simple imperative programming language. We explain our design decisions and also demonstrate the suitability of a dynamic language such, as Python, for this task.
