The many/2 parser takes a parser and attempts to match it on the input multiple (including possibly zero) times. Accepts options min: and max: to modify how many times the included parser must match for many to match.

Examples

This test will need to be rewritten in terms of Ergo.diganose
# iex> Logger.disable(self())
# iex> alias Ergo.Context
# iex> import Ergo.{Combinators, Terminals}
# iex> parser = many(wc(), label: "Chars")
# iex> context = Ergo.parse(parser, "Hello World")
# iex> assert %Context{status: :ok, ast: [?H, ?e, ?l, ?l, ?o], input: " World", index: 5, col: 6, char: ?o} = context
