A library for Dart developers.

Created from templates made available by Stagehand under a BSD-style license.

Usage

A simple usage example:

import 'package:Dart_Searchify/Dart_Searchify.dart';

main() {
    String patternString = "abcdef";
    String testString = "abcdefghijabcdef";
    
    //setting first pattern string
    Pattern pattern = Pattern(patternString);
  
    //now compare testString with pattern
    if(pattern.matches(testString, Search.RABIN_KARP)) {
      print("Pattern match found!");
    } else {
      print("Pattern match not found.");
    }
    
    /*
    * Note Matcher is an interface having to choose algorithm used for string matching
    *  In this case it uses Rabin Karp Algorithm for pattern matching 
    */
}

About Package

As the package provides a couple of string search algorithms some of them are listed below.

Algorithm	Processing Time	Matching time	Space
Naive string-search algorithm	none	Θ(nm)	none
Rabin–Karp algorithm	Θ(m)	average Θ(n + m),worst Θ((n−m)m)	O(1)
Knuth–Morris–Pratt algorithm	Θ(m)	Θ(n)	Θ(m)
Boyer–Moore string-search algorithm	Θ(m+k)	best Ω(n/m), worst O(mn)	Θ(k)
Two-way string-matching algorithm	Θ(m)	O(m+n)	O(1)

More coming soon..
