Scala example source code file (Formatting.scala)

This example Scala source code file (Formatting.scala) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Scala source code examples by using tags.

All credit for the original source code belongs to; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

Scala tags/keywords

compiler, formatting, list, nsc, string

package interpreter

import util.stringFromWriter

trait Formatting {
  def prompt: String

  def spaces(code: String): String = {
    /** Heuristic to avoid indenting and thereby corrupting """-strings and XML literals. */
    val tokens = List("\"\"\"", "</", "/>")
    val noIndent = (code contains "\n") && (tokens exists code.contains)

    if (noIndent) ""
    else prompt drop 1 map (_ => ' ')
  /** Indent some code by the width of the scala> prompt.
   *  This way, compiler error messages read better.
  def indentCode(code: String) = {
    val indent = spaces(code)
    stringFromWriter(str =>
      for (line <- code.lines) {
        str print indent
        str print (line + "\n")
