    This is required for parsers that create AST nodes that need to be resolved in a rewrite step and need to report the source location in case of failure. It is also required when passing a result of a first-pass parser to a recursive parser to preserve line positions.

    Applies the specified parser when this parser fails.

    a orElse b succeeds if either of the parsers succeeds.

    In case both parsers fail, the Failure instance will be from the parser with the most successfully read characters. In the case of multiple failures having the same number of characters, the one with the highest precedence (this parser) will be chosen.

    Implementation note: The parameter is by-name to allow the definition of recursive parsers. In contrast to the former SDK parser combinators this is the only place where a parser with a by-name parameter is used whereas in all other places the additional cost is avoided.

  40. def repUntil[U](endCondition: Parser[U]): Parser[(List[String], Option[U])]

    Returns a parser that repeatedly applies this parser until either this parser fails or the specified end condition is met. The end condition will be applied after each successful invocation of this parser.

    The result of the returned parser is a tuple consisting of the list containing the result of the invocations of this parser plus the result of the end condition. The latter is returned as an Option as it might be empty when the parsing finished because of this parser failing.

    Note that it is more convenient to include the end condition in the repeating parser itself and use the simpler rep method. This combinator is an alternative if you need to know the result of the end condition.

  41. def repWith[U >: String](next: (U) ⇒ Parser[U]): Parser[List[U]]

    Retrieves the part of the input consumed by this parser while discarding the result.

    This is useful in scenarios where many string-based parsers are combined and produce a deeply nested result like String ~ Option[String] ~ List[String] where it would require some boilerplate to concatenate the results. Using the source method, the entire text consumed by this combination of parsers will be returned.

    If you also need the position within the input or need to pass the result to a recursive parser manually, use the cursor method instead.
