语法分析器是函数绘图语言解释器的核心，因此语法分析器的构造是整个解释权构造的关键。语法分析器的构造分为两个重要步骤：规定语言的文法和根据文风编写程序。由于采用递归下降子程序方法，因此在文法的设计上要求是LL(1)文法。具体到此绘图语言，需要构造语法树的语言结构仅限于表达式，因为后继语义处理需要对表达式求值，而对语法树进行遍历即可得到表达式的值。 我们最终构造的是递归下降的语法分析器，要求文法是LL(1)文法，因此需要对二义文法进行改造：即先将文法改写为非二义文法，消除左递归，提取公共左因子，最后转换为产生式与递归子程序有对应关系的形式，形成最终的文法。

This book explains how to write device drivers for the newest members of the MicrosoftWindows family of operating systems using the Windows Driver Model (WDM). In this Introduction, I LL explain who should be reading this book, the organization of the book, and how to use the book most effectively. You LL also find a note on errors and a section on other resources you can use to learn about driver programming. Looking ahead, Chapter 1 explains how the two main branches of the Windows family operate internaLLy, what a WDM device driver is, and how it relates to the rest of Windows.

ANTLR 接受3类语法规范——语法分析程序，词法分析程序lexers，和树语法分析程序(也 叫树行者)。 由ANTLR使用LL(k) 分析用于全部3 语法变型，由于语法说明相似，因而产生 的lexers 和语法分析程序表现得也类似。 产生的识别程序易读，你可以查看输出的内容来 消除很多关于ANTLR机理的问题。
