代码格式化:如何对齐<-forfor-comprehension？

我for comprehension喜欢这样的:

 private[helper] def myMethod(name: String, index: Long) = {
   for {
  result1  <- httpUtilities.getLowIndexes(index)
  result2    <- myFacade.queryMaterial(result1)
  result3 <- httpUtilities.someMethod(result2)
  } yield result3
 }

我想要的是<-在列中对齐特殊字符,以便上面的代码转换为:

private[helper] def myMethod(name: String, index: Long) = {
   for {
      result1  <- httpUtilities.getLowIndexes(index)
      result2  <- myFacade.queryMaterial(result1)
      result3  <- httpUtilities.someMethod(result2)
  } yield result3
 }

我可以在设置 - >代码样式 - > Scala =>包装和大括号 - >'匹配'和'大小写'语句 - >在Intellij中对齐列'case'分支但是如何对其进行匹配案例语句<-里面的人物for-comprehension.

Scalafmt可以做到这一点,它可以作为IDEA插件使用,并且还可以通过许多其他方式打包.

您希望使用此align=more功能,如此处所述.文档显示了以下对齐示例:

val x  = 2 // true for assignment
val xx = 22

case object B  extends A // false for `extends`
case object BB extends A

q  -> 22 // true for various infix operators
qq -> 3  // and also comments!

for {
  x  <- List(1) // true for alignment enumerator
  yy <- List(2)
} yield x ** xx

x match { // true for multiple tokens across multiple lines
  case 1  => 1  -> 2  // first
  case 11 => 11 -> 22 // second

  // A blank line separates alignment blocks.
  case `ignoreMe` => 111 -> 222
}

// Align assignments of similar type.
def name   = column[String]("name")
def status = column[Int]("status")
val x      = 1
val xx     = 22

// Align sbt module IDs.
