Array Compare

[HeidiR]

If there an easy way to compare two 1D arrays similar to StringCompare ( "string1", "string2")?

Like: ArrayCompare ($ar1, $ar2)

Thanks for the info. I didn't find what I was looking for so I wrote my own (below).

CODE

Func array_compare($ar1, $ar2)

Local $str1="", $str2=""

For $i = 0 to ubound($ar1) -1

$str1 &= $ar1[$i]

Next

For $i = 0 to ubound($ar2) -1

$str2 &= $ar2[$i]

Next

Return StringCompare($str1, $str2, 1)

Endfunc

You can probably do a bit better than that

Func _ArrayStringCompare($avArray1, $avArray2, $iFlag = 0)
    Local $iUpper = UBound($avArray1)
    If UBound($avArray2) < $iUpper Then $iUpper = UBound($avArray2)

    Local $iCmp
    For $i = 0 To $iUpper - 1
        $iCmp = StringCompare($avArray1[$i], $avArray2[$i], $iFlag)
        If $iCmp Then Return $iCmp
    Next

    Return 0
EndFunc

Your method would fail on

$avArray1 = ["a", "b"]

$avArray2 = ["ab"]

It would report the two arrays to be equal (they're not).

I wrote a set of functions for dumping information from variables a while ago. You can find it here. If you include that file, you can do something like this:

#include <Variable.au3>

$array = StringSplit('Hello', '')
$array2 = StringSplit('Hello!', '')

If _VarDump($array) == _VarDump($array2) Then
; Match
EndIf

I don't know how efficient that would be though.

*Off topic note: _VarDump doesn't work on structs in the current version of AutoIt.

Thanks for the code suggestions guys! They were very helpful! :-)
