random_unicode 0.2.2

A library to generate random Unicode strings within the given range(s).

A library to generate random Unicode strings within the given range(s)

Features

• Generates an arbitrary Unicode string
• Allows to limit destination to a certain list of character ranges
• Contains helper constructors for ASCII characters, ASCII alpha, ASCII alphanumeric, numeric (decimal), hexadecimal, BMP (basic multilingual plane) and valid filename (when several characters are excluded to avoid issues under Windows)

Usage

The working example which can also be found in the repository in example/random_unicode_example.dart

import 'package:random_unicode/random_unicode.dart';

/// Entry point
///
void main(List<String> args) {
  // Getting minimum and maximum string length
  // from the command-line arguments
  //
  final argCount = args.length;
  final minStrLen = (argCount <= 0 ? 100 : int.parse(args[0]));
  final maxStrLen = (argCount <= 1 ? minStrLen : int.parse(args[1]));

  // Creating the string generator
  //
  final u = RandomUnicode()
    ..addIncluded(min: 0x20, max: 0x7F)
    ..addIncluded(min: 0x100, max: 0x200)
    ..addIncluded(min: 0x1000, max: 0x2000)
    ..addExcluded(charCodes: r'BEZbez'.codeUnits);

  // Generating the string
  //
  final str = u.string(minStrLen, maxStrLen);

  // Showing the result
  //
  print('Len: $minStrLen <= ${str.length} <= $maxStrLen\n$str');
