parsley 0.1.1

A simple but powerful parsing engine

parsley

Is your domain logic littered with parsing?

Parsley is a simple but powerful parsing engine that uses inference to automatically find the correct parser for the required input output.

Getting Started

Simply import the package into your project and forget about parsing forever!

parse(value); // to parse

registerHandler(parsingFunction); // registers custom parser

Example

import 'package:parsley/parsley.dart';

void main() {
  DateTime date = parse("2020-02-12");
  int textToInt = parse("5");           // 5
  bool textToBool = parse("true");      // true
  int stringToInt = parse("5");         // 5
  String intToString = parse(5);        // "5"
  bool intToBool = parse(1);            // true
  int doubleToInt = parse(5.5);         // 5
  double stringToDouble = parse("5.5"); // 5.5
  List<String> intToStringList = parse([1, 8, 3]); // ['1', '8', '3']
  List<int> StringListToIntList = parse(["1", "8", "3"]);

  // register custom parsers
  USD convertEuroToUSD(Euro euro){
    return USD(euro.value * 1.1);
  }
  Euro convertUSDToEuro(USD usd){
    return Euro(usd.value * 0.85);
  }
  parsely.registerHandler(convertEuroToUSD);
  parsely.registerHandler(convertUSDToEuro);
  USD usd = USD(15);
  Euro euro = parse(usd);
  print(euro);
}

class USD{
  final double value;
  USD(this.value);
}

class Euro{
  final double value;
  Euro(this.value);
}
