Parsing #1

Leonidas Fegaras. Parsing #1. Parser. A parser recognizes sequences of tokens according to some grammar and generates Abstract Syntax Trees (ASTs)? A context-free grammar (CFG) has a finite set of terminals (tokens)? a finite set of nonterminals from which one is the start symbol

Predictive Parsing

Predictive Parsing. Lecture 9 Wed, Feb 9, 2005. Predictive Parsing Table. The parse table has one row for each nonterminal, one column for each terminal and $. $ is the end-of-file marker. Each cell in the table represents a combination ( A , a) of a nonterminal A and a terminal a.

Recursive Descent Parsers

Recursive Descent Parsers. Lecture 6 Mon, Jan 31, 2005. Recursive Descent Parser. Each nonterminal in the grammar is implemented as a function. Begin with the start symbol S of the grammar by calling the function S() .
