programming-languages - 元循环评估器的条件

Question

是否有语言必须满足的任何条件才能为该语言编写元循环评估器？我可以为 BASIC 或 Python 编写一个吗？

Answer 1

报价 Reg Braithwaite :

The difference between self-interpreters and meta-circular interpreters is that the latter restate language features in terms of the features themselves, instead of actually implementing them. (Circular definitions, in other words; hence the name). They depend on their host environment to give the features meaning.

鉴于此，允许为它们编写元循环解释器的语言的主要特征之一是 homoiconicity ，也就是说，程序的主要表示是语言本身的原始数据结构。 Lisp 展示了这一点，因为程序本身被表示为列表。
