= FuzzyHash

Should accept strings and retrieve based on them.

    l = FuzzyHash.new
    l['asd'] = 'qwe'
    l['asd'].should == 'qwe'
  
Should accept strings, but the second time you set the same string, it should overwrite.

    l = FuzzyHash.new
    l['asd'] = 'asd'
    l['asd'] = 'qwe'
    l['asd'].should == 'qwe'

Should accept regexs too.

    l = FuzzyHash.new
    l[/asd.*/] = 'qwe'
    l['asdqweasd'].should == 'qwe'

Should accept regexs too, but the second time you set the same regex, it should overwrite.

    l = FuzzyHash.new
    l[/asd/] = 'asd'
    l[/asd/] = 'qwe'
    l['asdqweasd'].should == 'qwe'

Should accept regexs too with the match.

    l = FuzzyHash.new
    l[/asd.*/] = 'qwe'
    l.match_with_result('asdqweasd').should == ['qwe', 'asdqweasd']

Should accept regexs that match the whole strong too with the match.

    l = FuzzyHash.new
    l[/asd/] = 'qwe'
    l.match_with_result('asd').should == ['qwe', 'asd']

Should prefer string to regex matches.

    l = FuzzyHash.new
    l['asd'] = 'qwe2'
    l[/asd.*/] = 'qwe'
    l['asd'].should == 'qwe2'

Should allow nil keys.

    l = FuzzyHash.new
    l[nil] = 'qwe2'
    l['asd'] = 'qwe'
    l['asd'].should == 'qwe'
    l[nil].should == 'qwe2'

Should allow boolean keys.

    l = FuzzyHash.new
    l[false] = 'false'
    l[true] = 'true'
    l[/.*/] = 'everything else'
    l[true].should == 'true'
    l[false].should == 'false'
    l['false'].should == 'everything else'

Should pick between the correct regex.

    hash = FuzzyHash.new
    hash[/^\d+$/] = 'number'
    hash[/.*/] = 'something'
    hash['123asd'].should == 'something'

Should be able to delete by value for hash.

    l = FuzzyHash.new
    l[nil] = 'qwe2'
    l['asd'] = 'qwe'
    l['asd'].should == 'qwe'
    l[nil].should == 'qwe2'
    l.delete_value('qwe2')
    l[nil].should == nil

Should be able to delete by value for regex.

    l = FuzzyHash.new
    l[/qwe.*/] = 'qwe2'
    l['asd'] = 'qwe'
    l['asd'].should == 'qwe'
    l['qweasd'].should == 'qwe2'
    l.delete_value('qwe2')
    l['qweasd'].should == nil

Should iterate through the keys.

    l = FuzzyHash.new
    l[/qwe.*/] = 'qwe2'
    l['asd'] = 'qwe'
    l['zxc'] = 'qwe'
    l.keys.size.should == 3

Should iterate through the values.

    l = FuzzyHash.new
    l[/qwe.*/] = 'qwe2'
    l['asd'] = 'qwe'
    l['zxc'] = 'qwelkj'
    (['qwe2','qwe','qwelkj'] & l.values).size.should == 3

Should clear.

    l = FuzzyHash.new
    l[/qwe.*/] = 'qwe2'
    l['asd'] = 'qwe'
    l['zxc'] = 'qwelkj'
    l.clear
    l.empty?.should == true
 
Should handle equality.

    l_1 = FuzzyHash.new
    l_1[/qwe.*/] = 'qwe2'
    l_1['asd'] = 'qwelkj'
    l_1['zxc'] = 'qwe'
    l_2 = FuzzyHash.new
    l_2['zxc'] = 'qwe'
    l_2['asd'] = 'qwelkj'
    l_2[/qwe.*/] = 'qwe2'
    l_1.should == l_2

Should return the value when adding the value.

    h = FuzzyHash.new
    (h[/asd/] = '123').should == '123'
    (h['qwe'] = '123').should == '123'

That's It.
