有没有可以分析非上下文无关文法的工具？
Is there a tool that can analyse non-context-free grammars?
我知道有几种工具可以定义 "easily" 上下文无关语法，例如定义 DSL。
但是有没有可以分析非上下文无关文法的工具呢？
Definite clause grammars can be used to generate parsers for non-context-free grammars. There are also several parser generators for context-sensitive grammars, such as LuZc.
