Special-Purpose Functional Languages

9619644 Kamin该项目的目标是通过专注于特殊用途的函数式语言，促进技术从函数式编程社区转移到更广泛的编程社区。建议的工作重点是设计和实现的功能语言的ASCII文件处理，暂称为FPERL。这以两种相互加强的方式实现了这一目标。首先，FPERL将成为AWK和PERL等语言的函数式替代品;它的开发将为这个领域带来光明，并希望获得新的函数式程序员用户社区。其次，FPERL处理器的构造将基于一类独特的专用语言：元编程语言（也称为程序生成器）。处理器的组件--词法分析器、解析器、去糖器等等--都将用专门为该类型组件设计的函数式元编程语言编写。这些元编程语言将作为FPERL的扩展开发，从而导致不寻常的靴子过程。这项研究将产生关于各种专用语言领域的新知识-文件处理，解析等;关于元编程作为一种普遍适用的编程方法;以及关于支持元编程的语言设计。 ***

9619644 Kamin The goal of this project is to promote technology transfer from the functional programming community into the wider programming community, by concentrating on special-purpose functional languages. The proposed work focuses on the design and implementation of a functional language for ASCII file processing, tentatively called FPERL. This addresses the goal in two mutually-reinforcing ways. First, FPERL is to be a functional alternative to languages like AWK and PERL; its development will shed light on this domain and will, it is hoped, garner a user community of new functional programmers. Second, the construction of the FPERL processor will be based on a unique class of special- purpose languages: meta-programming languages (also called program generators). The components of the processor - lexical analyzer, parser, de-sugarer, and so on - will each be written in a functional meta-programming language specially designed for that type of component. These meta-programming languages will be developed as extensions to FPERL, resulting in an unusual boot- strapping process. This research will produce new knowledge about a variety of special-purpose language domains - file processing, parsing, and so on; about meta-programming as a generally applicable programming methodology; and about the design of languages to support meta-programming. ***
