12.  def left[A, B, C >: B](p: Parsley[A], op: ⇒ Parsley[(C, A) ⇒ B], x: C)(implicit wrap: (A) ⇒ C): Parsley[C]

    This combinator handles left-associative parsing, and application of, zero or more binary operators between zero or more values.

    This combinator handles left-associative parsing, and application of, zero or more binary operators between zero or more values.

    First parse p, then parse op followed by a p repeatedly. The results of the ps, x1 through xn, are combined with the results of the ops, f1 through fn-1, with left-associative application: fn-1(fn-2(..f1(x1, x2).., xn-1), xn). This application is then returned as the result of the combinator. If p or op fails having consumed input at any point, the whole combinator fails. If no p could be parsed, this combinator will return a default result x.

    Compared with chain.left, this combinator allows the types of the operators to more accurately encode their associativity in their types. The recursive values of type C may only be applied on the left-hand side of the operators.

    A

    the type of the values.

    B

    the type returned by the operator, which must be a subtype of the result type C.

    C

    the result type of the chain, which also fits into the recursive application site of the operators.

    p

    the value to be parsed.

    op

    the operator between each value.

    x

    the default value to return if no ps can be parsed.

    wrap

    a function that can convert the value type into the result type, this is provided automatically when A <:< C.

    returns

    a parser that parses alternating p and op, ending in a p and applies their results left-associatively or returns x if no p was parsed.

    Example:

    1. scala> import parsley.expr.infix
       scala> import parsley.character.{digit, char}
       scala> sealed trait Expr
       scala> case class Add(x: Expr, y: Num) extends Expr
       scala> case class Num(x: Int) extends Expr
       scala> val expr = infix.left[Num, Add, Expr](digit.map(d => Num(d.asDigit)), char('+') #> Add, Num(0))
       scala> expr.parse("1+2+3+4")
       val res0 = Success(Add(Add(Add(Num(1), Num(2)), Num(3)), Num(4)))
       scala> expr.parse("")
       val res1 = Success(Num(0))

    Since

    4.0.0

    See also

    chain.left for a version where the types must match, allowing for flexibility to change the associativity.
