Scala example source code file (Parsers.scala)

This example Scala source code file (Parsers.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

exception, parseexception, parsers, string, tree

The Parsers.scala Scala example source code

package scala
package reflect
package macros

 * <span class="badge badge-red" style="float: right;">EXPERIMENTAL</span>
 *  A slice of [[scala.reflect.macros.blackbox.Context the Scala macros context]] that
 *  exposes functions to parse strings with Scala code into trees.
trait Parsers {
  self: blackbox.Context =>

  /** Parses a string with a Scala expression into an abstract syntax tree.
   *  Only works for expressions, i.e. parsing a package declaration will fail.
   *  @throws [[scala.reflect.macros.ParseException]]
  def parse(code: String): Tree

/** Indicates an error during [[scala.reflect.macros.Parsers#parse]].
case class ParseException(pos: scala.reflect.api.Position, msg: String) extends Exception(msg)
