Scala Parser Combinators Scala Parser Combinators是一个用于构建解析器的库,它允许用户通过组合不同的解析器来解析各种输入。Scala Parser Combinators是基于Scala语言的,它提供了一种简洁、易于理解的方式来定义解析器。 1.1. 优势 简洁易懂:Scala Parser Combinators的语法简单,易于理解和使用。 灵活性:Scala Parse...

(1)需要添加引用:“scala-parser-combinators_2.12-1.0.6.jar”,这个包在scala安装路径的lib环境下可以找到。主要用于解决import scala.util.parsing.json._这个引用找不到的问题。 (2)需要scala.concurrent.util. Unsafe这个类 (3)JDK环境建议为1.8环境。
Anorm is providing parser combinators other than the most common ~ one: ~>, <~.import anorm.{ SQL, SqlParser }, SqlParser.{ int, str } // Combinator ~> val String = SQL("SELECT * FROM test").as((int("id") ~> str("val")).single) // row has to have an int column 'id...
最近几天看了些文章(Learn by Example: Scala Parser Combinators,An Introduction To Scala Parser Combinators)学习了scala中的Parser的一些使用 这边以一个解析JSON的例子来记录一些笔记 首先是一些连接符(翻译自第一篇文章): | 选择连接符,当左边或右边的Parser成功时成功。

其中,fromStatements,groupStatements,whereExpr等有是一个单独的解析器,通过scala中已经提供的parser combinators(解析器组合子),例如(~>,~,opt()...)等,将单独的解析器组合起来,可以得到更复杂的解析器,类似于lego积木,你编写一个解析 器,parserA, 只能解析某段特殊的文本,这个段文本的模式我们用patternA来表示...
