　　全书共57章，分为六个部分：第一部分介绍了什么是dsl，dsl的用途，如何实现外部ds和内部dsl，如何生成代码，语言工作台的使用方法；
第二部分介绍了各种dsl，分别讲述了语义模型、符号表、语境变量、构造型生成器、宏和通知的工作原理和使用场景；
第三部分分别揭示分隔符指导翻译、语法指导翻译、bnf、易于正则表达式表的词法分析器、递归下降法词法分析器、解析器组合子、解析器生成器、树的构建、嵌入式语法翻译、内嵌解释器、外加代码等；
第四部分介绍了表达式生成器、函数序列、嵌套函数、方法级联、对象范围、闭包、嵌套闭包、标注、解析数操作、类符号表、文本润色、字面量扩展的工作原理和使用场景；
第五部分介绍了适应性模型、决策表、依赖网络、产生式规则系统、状态机等计算模型的工作原理和使用场景；
第六部分介绍了基于转换器的代码生成、模板化的生成器、嵌入助手、基于模型的代码生成、无视模型的代码生成和代沟等内容。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
