StringReverse UDF

[Daniel W. 0]

Hi,

i did this to learn AutoIT bit more but wOuter told me its a bit faster then the other one so here it is:

Func StringReverse( $s_string ) 
    Local $string
    If StringLen($sString) >= 1 Then
        Local $split = StringSplit( $s_string , '' ) 
        
        For $b = $split[0] to 1 Step -1 
            $string &= $split[$b] 
        Next 
        Return $string 
    Else
        SetError(1)
        Return ""
    EndIf
EndFunc

You can use TimerInt and TimerDiff to check if it's Really faster..

wOuter did it

[16:24] M-3vent | *HardCore*  < 1 + 3 + 3 = 7 >: _StringReverse: 3136.18157484187 
StringReverse_Mine: 3153.86767657846 
StringReverse_Dan: 2469.65613484093 
[16:24] M-3vent | *HardCore*  < 1 + 3 + 3 = 7 >: using the same errorhandeling as in _StringReverse

If you want it really fast you can strip out things like error checking etc. this will make it fly.

Func StringReverse( $s_string ) 
     Global $string
     Local $split = StringSplit( $s_string , '' ) 
        
     For $b = $split[0] to 1 Step -1 
         $string &= $split[$b] 
     Next 
EndFunc

Thats not what i want ...

I just want a function that does the same but that i made. The faster speed is just something that happened without my idea

Is this statement based on a test or guess? would surprise me if a bit of error checking at the beginning would even be measurable....

My guess is that the real reason for this version to be faster is because of the usage of &=, which make "added on to a string" faster......

Before the separation of the Production and Beta includes we tried to make the UDF's work in both versions so this wasn't an option... now it is...

I have rewritten some other string functions and noticed that StringTrimRight/Left takes "much" time , so it mustn't be &= ...
