    Package structure

    The parsley package contains the Parsley class, as well as the Result, Success, and Failure types. In addition to these, it also contains the following packages and "modules" (a module is defined as being an object which mocks a package):

    • parsley.Parsley contains the bulk of the core "function-style" combinators, as well as the implicit classes which enable the "method-style" combinators.
    • parsley.combinator contains many helpful combinators that simplify some common parser patterns.
    • parsley.character contains the combinators needed to read characters and strings, as well as combinators to match specific sub-sets of characters.
    • parsley.debug contains debugging combinators, helpful for identifying faults in parsers.
    • parsley.io contains extension methods to run parsers with input sourced from IO sources.
    • parsley.expr contains the following sub modules:
    • parsley.implicits contains several implicits to add syntactic sugar to the combinators. These are sub-categorised into the following sub modules:
      • parsley.implicits.character contains implicits to allow you to use character and string literals as parsers.
      • parsley.implicits.combinator contains implicits related to combinators, such as the ability to make any parser into a Parsley[Unit] automatically.
      • parsley.implicits.lift enables postfix application of the lift combinator onto a function (or value).
      • parsley.implicits.zipped enables boths a reversed form of lift where the function appears on the right and is applied on a tuple (useful when type inference has failed) as well as a .zipped method for building tuples out of several combinators.
    • parsley.errors contains modules to deal with error messages, their refinement and generation.
      • parsley.errors.combinator provides combinators that can be used to either produce more detailed errors as well as refine existing errors.
    • parsley.lift contains functions which lift functions that work on regular types to those which now combine the results of parsers returning those same types. these are ubiquitous.
    • parsley.registers contains combinators that interact with the context-sensitive functionality in the form of registers.
    • parsley.token contains the Lexer class that provides a host of helpful lexing combinators when provided with the description of a language.
    • parsley.unsafe contains unsafe (and not thread-safe) ways of speeding up the execution of a parser.

final class Parsley[+A] extends AnyVal

This is the class that encapsulates the act of parsing and running an object of this class with parse will parse the string given as input to parse.

Note: In order to construct an object of this class you must use the combinators; the class itself is opaque.

  9. def parse[Err](input: String)(implicit arg0: ErrorBuilder[Err]): Result[Err, A]

    This method is responsible for actually executing parsers.

    This method is responsible for actually executing parsers. Given an input array, will parse the string with the parser. The result is either a Success or a Failure.

    input

    The input to run against

    returns

    Either a success with a value of type A or a failure with error message

  11. def unsafe(): Unit

    Using this method signifies that the parser it is invoked on is impure and any optimisations which assume purity are disabled.
