    This package contains various functionality that involve Scala's implicits mechanism.

    This package contains various functionality that involve Scala's implicits mechanism.

    This includes conversions from scala literals into parsers, as well as enabling new syntax on regular Scala values (such as Parsley's lift or zipped syntax). Automatic conversion to Parsley[Unit] is also supported within this package.

object lift

This module provides the "lift syntax", which enables a lift combinator on functions of arities up to 22, applying the function across the results of several parsers.

Source
lift.scala
Example: 

  1. scala> import parsley.character.char
scala> import parsley.implicits.lift.{Lift2, Lift3}
scala> case class Add(x: Int, y: Int)
scala> val p = Add.lift(char('a') #> 4, char('b') #> 5)
scala> p.parse("ab")
val res0 = Success(Add(4, 5))
scala> val f = (x: Int, y: Int, z: Int) => x * y + z
scala> val q = f.lift(char('a') #> 3, char('b') #> 2, char('c') #> 5)
scala> q.parse("abc")
val res1 = Success(11)
scala> q.parse("ab")
val res2 = Failure(..)
Since

3.0.0

Note

a limitation of this syntax is that it requires the function's type to be fully known. For a version of this syntax that behaves better with type inference, see zipped.
