Performance

A benchmark was added to test the performance of the library.

An internal design modification greatly improved the parsing speed and memory usage. Before the modification the benchmark measured 648.32s (≈10.8m) to execute the parsing of a huge JSON file. Now it only takes 6.7s, a bit more than 96 times faster!

API

  • Added the userState: GenericParser<StreamType, UserState, UserState> parser.
  • Now the run(userState: UserState, sourceName: String, input: StreamType) throws -> Result only returns the result of the parsing. As an example, if one wants to get the user state and the result at the same time:
let countLine = GenericParser<String, Int, Character>.endOfLine >>- { newLine in

    GenericParser<String, Int, Int>.userState >>- { userState in

        GenericParser(result: (newLine, userState + 1))

    }

}
  • Added the Parsec.runSafe(userState: UserState, sourceName: String, input: StreamType) -> Either<ParseError, Result> method. This new method does not throw exceptions but returns the result wrap in an Either type.
  • Added a parser returning the current source position: GenericParser.sourcePosition: GenericParser<StreamType, UserState, SourcePosition>
  • Various minor changes to conform to the Swift API design guide lines

  • Added ClosedInterval variant of ParsecType.oneOf()
  • Migration to Swift 2.2
