组合的非解析器/解析器生成器 [英] Combined unparser/parser generator

问题描述

是否有一个解析器生成器也实现相反的方向，即从相同的语法规范中解析域对象(又称漂亮打印)?据我所知，ANTLR不支持此功能.

Is there a parser generator that also implements the inverse direction, i.e. unparsing domain objects (a.k.a. pretty-printing) from the same grammar specification? As far as I know, ANTLR does not support this.

推荐答案

我已经用Java和Kotlin实现了一组Invertible Parser Combinator.解析器几乎是用LL-1样式编写的，它提供了解析和打印方法，后者提供了漂亮的打印机.

I have implemented a set of Invertible Parser Combinators in Java and Kotlin. A parser is written pretty much in LL-1 style and it provides a parse- and a print-method where the latter provides the pretty printer.
