It represents a regular expression and provides the logic to match the regular expression against strings.
它表示一个正则表达式并提供了使正则表达式与字符串相匹配的逻辑。
The nice thing about the regular expression is the ability to customize the regular expression used.
正则表达式的一个优点是能够定制所使用的正则表示式。
This USES the regular expression module (re) to create a compiled regular expression from the regular expression the user enters in line 8.
它使用正则表达式模块(re)，由用户在第8行输入的正则表达式创建已编译的正则表达式。
To use a regular expression in Squirrel Shell, you define the regular expression, compile it, make a comparison, then iterate over the results, if any.
要在SquirrelShell中使用正则表达式，需要先定义正则表达式，对其进行编译，进行比较，然后再迭代结果(如果有的话)。
Section 6.5 deals with regular expression string generation, which is a commonly asked question: "Given a regular expression, how do you find all the strings that match it?"
节介绍的是正则表达式字符串的生成问题，这是一个经常被问到的问题：“给定一个正则表达式，我们应该如何查找与之匹配的所有字符串呢？”
For example, the regular expression a will match the string abcdcba twice (the first and last a) and so will the regular expression b.
例如，正则表达式a匹配字符串abcdcba两次，正则表达式b 也是一样。
Alternatively, you can try to build the regular expression pattern yourself using the regular expression Builder.
另外，也可以使用Regular ExpressionBuilder自己构建正则表达式模式。

本文主要介绍基于编译器构造技术中的由正规表达式到最小化dfa的算法设计和实现技术，以及自动机转换正规式的方法。
The regular expression object is an object that contains a regular expression pattern along with flags that identify how to apply the pattern.
