递归下降解析算法(Recursive Descent Parsing)是一种自上而下的解析技术,广泛应用于编译器和解释器的设计中,用于分析编程语言或任何形式语言的语法结构。它根据给定的文法规则(通常采用巴科斯范式,即BNF形式)来解析输入串,通过一系列的函数调用模拟文法规则的递归定义,从而识别出输入中的语法结构。一、基本原理 递...
按我理解就是按照文法的定义自顶向下的写parser,符合程序员的直觉。先搞类,函数,然后控制结构(if f...

SnL-recursive-descent 是一种采用递归下降方法的语法分析器。它使用自顶向下和自底向上的方法来解析源代码。自顶向下的方法是从最高层开始,逐层分解,直到达到最底层。自底向上的方法是从最低层开始,逐层向上构建抽象语法树(AST)。 在SnL-recursive-descent 中,编译器首先使用自顶向下的方法将源代码解析为一个...
recursive descent parser (grammar) A "top-down"parserbuilt from a set of mutually-recursive procedures or a non-recursive equivalent where each such procedure usually implements one of the productions of thegrammar. Thus the structure of the resulting program closely mirrors that of the grammar it...

CSC173: Project 2 Recursive Descent and Table-Driven Parsing The goal of this project is to demonstrate your understanding of the formal model of context-free grammars and parsing by applying the principles of the model to a specific grammar (details bel
A recursive descent parser consists of a collection of mutually recursive procedures or functions. Many compilers are implemented with the recursive descent technique, with a so-called look-ahead facility. In this chapter we discuss the technique with and without look ahead and study its properties ...
