#include <StringConstants.au3>
#include <Array.au3>
Global $g_sString, $g_sOutput
$g_sString = "D97,D96,,D85,D86,D85,D86,D85,D86,D85,,D86,D85,D86,D85,D86"

; remove duplicates :
$g_sOutput = _ArrayToString(_ArrayUnique(StringSplit($g_sString, ",", $STR_NOCOUNT), 0, 0, 0, $ARRAYUNIQUE_NOCOUNT), ",")
ConsoleWrite('> >>> String Output = ' & $g_sOutput & @CRLF)

Moved to the appropriate forum, as the Developer General Discussion forum very clearly states:


General development and scripting discussions. If it's super geeky and you don't know where to put it - it's probably here.

Do not create AutoIt-related topics here, use the AutoIt General Help and Support or AutoIt Technical Discussion forums.

Another way:

Local $sString = "D97,D96,,D85,D86,D85,D86,D85,D86,D85,,D86,D98,D85,D86,D85,D86"

; remove duplicates :
Local $sOutput = StringRegExpReplace(StringRegExpReplace($sString, "(\b\w+\b,?)(?=.*?\1)", ""), ",+", ",")
ConsoleWrite($sString & @LF & $sOutput & @LF)

Another example.

#include <Debug.au3>; Included For _DebugArrayDisplay() use only.
; https://www.autoitscript.com/forum/topic/201783-unique-elements-in-array-moved/?do=findComment&comment=1447861

Local $a[3] = [ _
        "D97,,,D96,D85,D85,D86,,D8!6,D85,D8!6,,CD85,,D86,D98,,,,,D85,D86,CD85,,D86", _
        ",,D85,D24,,,,,D85", _

For $i = 0 To UBound($a) - 1
    ; Remove duplicate elements; Remove leading and trailing commas; Remove all the commas followed by a comma (one comma remains from a whole group of commas).
    ;$a[$i] = StringRegExpReplace($a[$i], "(\b\w+\b),*(?=.*?\1)|(^,+|,+$)|,+(?=,)", "")

    ; Overcomes "\b" problem by matching non-word characters embedded in the comma separated "test" string.
    ;$a[$i] = StringRegExpReplace($a[$i], "((?<=,|^)[^,]+(?=,)),*(?=.*?\1)|(^,+|,+$)|,+(?=,)", "")

    ; This latest RE example overcomes the error of the missing "D85" because "D85" mistakenly matched "CD85".
    $a[$i] = StringRegExpReplace($a[$i], "((?<=^|,)[^,]+(?=,)),*(?=.*?,\1,?)|(^,+|,+$)|,+(?=,)", "") ; <----------- The working Reg. Exp.



Edited by Malkey
I thought mikell's following example was the way to go. But now, I managed to overcome the problem that using "\b" created.

Not as great for long strings, but anyways add in to the mix:

Edit: Now as Fast as doing this with  Scripting.Dictionary

Func StringUnique_Delim($sString = "", $delim = ",")
    Return StringTrimLeft(StringRegExpReplace($delim & $sString, '(' & $delim & '[^' & $delim & ']+(?=' & $delim & '))(?=.*\1)|' & $delim & '(?=' & $delim & ')', ""), 1)
EndFunc   ;==>StringUnique_Delim
