Code-formatting: How to align multiline code to special characters?

问题

Is IDEA or one of its plugins capable of aligning code to special characters?

I mean so that the code

Map(
  'name -> "Peter",
  'age -> 27,
  'company -> "Foobar"
)

is transformed to

Map(
  'name    -> "Peter",
  'age     -> 27,
  'company -> "Foobar"
)

Example2:

execute("x", true, 27)
execute("foobar", false, 0)

transformed to

execute("x"     , true , 27)
execute("foobar", false, 0 )

You can align case statements, however:

value match {
  case s: String => Some(java.lang.Long.parseLong(s))
  case bi: BigInt => Some(bi.longValue)
  case _ => None
}

Like so:

value match {
  case s: String  => Some(java.lang.Long.parseLong(s))
  case bi: BigInt => Some(bi.longValue)
  case _          => None
}

Use option:

Settings -> Code Style -> Scala => Wrapping and Braces -> 'match' and 'case' statements -> Align in columns 'case' branches

In IDEA 12 if you're using the Scala plugin you can configure "Align when multiline" for many things, including method parenthesis. Your particular example of multiple invokations on separate lines is not supported however.

Code formatter seems to be a solution.
