abstract class Parser[+T] extends CompletionSupport.Parser[T] with CombinableParser[T, Parser]

The root class of completion parsers, overloading the Parser class. Completion parsers are functions from the Input type to ParseResult, with the addition of a completions function from the Input type to an instance of Completions

    An operator to specify the completion tag meta-data of a parser in JSON format (empty by default).

    A parser combinator that parameterizes a subsequent parser with the result of this one.

    A parser combinator that parameterizes a subsequent parser with the result of this one.

    Use this combinator when a parser depends on the result of a previous parser. p should be a function that takes the result from the first parser and returns the second parser.

    p into fq (with fq typically {x => q}) first applies p, and then, if p successfully returned result r, applies fq(r) to the rest of the input.

    From: G. Hutton. Higher-order functions for parsing. J. Funct. Program., 2(3):323--343, 1992.

    fq

    a function that, given the result from this parser, returns the second parser to be applied

    Changes the failure message produced by a parser.

    Changes the failure message produced by a parser.

    This doesn't change the behavior of a parser on neither success nor error, just on failure. The semantics are slightly different than those obtained by doing | failure(msg), in that the message produced by this method will always replace the message produced, which is not guaranteed by that idiom.

    For example, parser p below will always produce the designated failure message, while q will not produce it if sign is parsed but number is not.

    def p = sign.? ~ number withFailureMessage  "Number expected!"
    def q = sign.? ~ number | failure("Number expected!")
    msg

    The message that will replace the default failure message.

    A parser combinator for non-back-tracking sequential composition which only keeps the right result.

    A parser combinator for non-back-tracking sequential composition which only keeps the right result.

    p ~>! q succeeds if p succeds and q succeds on the input left over by p. In case of failure, no back-tracking is performed (in an earlier parser produced by the | combinator).

    q

    a parser that will be executed after p (this parser) succeeds -- evaluated at most once, and only when necessary

    returns

    a Parser that -- on success -- reutrns the result of q. The resulting parser fails if either p or q fails, this failure is fatal.
