ANTLR v3 is the most powerful, easy-to-use parser generator built to date, and represents the culmination of more than 15 years of research by Terence Parr. This book is the essential reference guide to using this completely rebuilt version of ANTLR
ANTLRWorks is a novel grammar development environment for ANTLR v3 grammars written by Jean Bovet (with suggested use cases from Terence Parr). It combines an excellent grammar-aware editor with an interpreter for rapid prototyping and a language-ag
ANTLR—Another Tool for Language Recognition，其前身是PCCTS，它为包括Java，C++，C#在内的语言提供了一个通过语法描述来自动构造自定义语言的识别器（recognizer），编译器（parser）和解释器（translator）的框架。ANTLR可以通过断言（Predicate）解决识别冲突；支持动作（Action）和返回值（Return Value）来；更棒的是，它可以根据输入自动生成语法树并可视化的显示出来（这一点我将在下面的例子中演示）。
antlrworks-1.4.3 and 1.2.2 ANTLR, 语言识别的另一个工具(ANother Tool for Language Recognition ),(前身是 PCCTS)是一种语言工具，它提供了一个框架，可以通过包含Java,C++,或C#动作（action）的语法描述来构造语言识别器，编译器和解析器。
