Gigglestick Posted April 12, 2011 Share Posted April 12, 2011 Dim $strTestReference, $arrTestArray[3][3][3] $strTestReference = StringFormat("$arrTestArray[%d][%d][%d]", $x, $y, $z) Assign($strTestReference, $strValue) I'm just curious why Assign can't be used with arrays so that something like the code above could be accomplished (just thrown together, not what I'd actually do). If it did, it would be easy to create UDFs to populate and display arrays of unlimited dimensions (within the bounds of variable limits). I'm not sure where an array with more than a handful of dimensions would be needed, I'm just curious about it more than trying to prove a point. Probably moreso than using it in AutoIt, I'm curious what prevented it in the implementation of the Assign function. Is it limitations of the C++ language or compiler?

PsaltyDS Posted April 12, 2011 Share Posted April 12, 2011 All you need is to Eval() the entire array to a known temp variable then Assign() it back. #include <Array.au3> Global $arrTestArray[3][3] = [[0, 0, 0], [0, 0, 0], [0, 0, 0]] _ArrayDisplay($arrTestArray, "Before") $strTestReference = "arrTestArray" $strValue = "Changed!" $aTemp = Eval("arrTestArray") $x = Random(0, UBound($aTemp) - 1) $y = Random(0, UBound($aTemp, 2) - 1) $aTemp[$x][$y] = $strValue Assign($strTestReference, $aTemp) _ArrayDisplay($arrTestArray, "After") Valuater's AutoIt 1-2-3, Class...

Gigglestick Posted April 13, 2011 Author Share Posted April 13, 2011 (edited) Interesting. The logic seems sound. Below is what I was originally thinking. The goal being to create an _ArrayDisplay type function that would work for an array of any dimensions. My problem area is between the ========= blocks. expandcollapse popup; My preferred variable nomenclature: ; $gxVariable = global variable of type x ; $lxVariable = local variable of type x ; $axVariable = variable of type x, passed as an argument ; x being s=str, n=int, b=bool, a=array, etc. Global $gaTestArray[3][3][3] = [[[1,2,3],[4,5,6],[7,8,9]],[[10,11,12],[13,14,15],[16,17,18]],[[19,20,21],[22,23,24],[25,26,27]]] ConsoleWrite(_ArrayGetString($gaTestArray)) ; This would be the user-called function so the user can call _ArrayGetString($array) ; instead of having to create the dummy string and counter array variables since they're ByRef Func _ArrayGetString(ByRef $aaArray, $asIndentChar="") Local $lsOutput="" Local $laCounters=[UBound($aaArray,0)] ; 1-based to avoid confusion Return __ArrayGetStringRecursed($aaArray, $lsOutput, $laCounters) EndFunc ; Returns a string from an array of unknown dimensions, indenting the line farther for each dimension deep ; Uses an array of counters, one per dimension ; $asIndentChar could be a space or a tab to visually indent in addition to the numeric reference Func __ArrayGetStringRecursed(ByRef $aaArray, ByRef $asIndentChar, ByRef $asOutput, ByRef $aaCounters, $anDimension=1) If Not IsArray($aaArray) Then Return SetError(1, 0, -1) If Not IsArray($aaCounters) Then ReDim $aaCounters[UBound($aaArray,0)+1] ; 1-based to avoid confusion EndIf ; Recurse until we're at the last dimension of the array If UBound($aaArray,0) > $anDimension Then $asOutput &= __ArrayGetStringRecursed($aaArray, $asOutput, $aaCounters, $anDimension+1) EndIf ; ================================================== ; This is where I'm getting hung up, accessing an array reference ; built on the fly for an unknown amount of array dimensions For $aaCounters[$anDimension] = 0 to UBound($aaArray, $anDimension) Local $i, $lsArrayReference = "", $lsOutputReference="" For $i = 1 to UBound($aaArray,0) $lsArrayReference &= "[" & $aaCounters[$i] & "]" $lsOutputReference &= $aaCounters[$i] & "," Next $lsOutputReference = StringTrimRight($lsOutputReference,1) ; Trailing comma ; We should end up with something like $lsArrayReference = "$aaArray[0][0][x]" with x incrementing on each loop ; First run appends output from $lsArrayReference = "$aaArray[0][0][x]" for x from 0 to 2 ; Second run appends output from $lsArrayReference = "$aaArray[0][1][x]" for x from 0 to 2 ; Third run appends output from $lsArrayReference = "$aaArray[0][2][x]" for x from 0 to 2 ; Fourth run appends output from $lsArrayReference = "$aaArray[1][2][x]" for x from 0 to 2 $asOutput &= $lsOutputReference & " = " & _ __IndentString($anDimension, $asIndentChar) & _ Eval("$aaArray" & $lsArrayReference) & @CRLF Next Return $asOutput & @CRLF ; Extra CRLF for a spacer ; ================================================== EndFunc Func __IndentString($anCount, $asChar=" ") Local $lsReturn="" While StringLen($lsReturn) < $anCount $lsReturn &= $asChar WEnd Return $lsReturn EndFunc 3-dimensional array output: 0,0,0=1 0,0,1= 2 0,0,2= 3 0,1,0=4 0,1,1= 5 0,1,2= 6 0,2,0=7 0,2,1= 8 0,2,2= 9 1,0,0=10 1,0,1= 11 1,0,2= 12 1,1,0=13 1,1,1= 14 1,1,2= 15 1,2,0=16 1,2,1= 17 1,2,2= 18 2,0,0=19 2,0,1= 20 2,0,2= 21 2,1,0=22 2,1,1= 23 2,1,2= 24 2,2,0=25 2,2,1= 26 2,2,2= 27 Edited April 13, 2011 by c0deWorm My UDFs: ExitCodes Link to comment Share on other sites More sharing options...

Gigglestick Posted April 13, 2011 Author Share Posted April 13, 2011 $sArrayRead = Execute('$aArray' & $sArrayFetch) Nice. So that's what I was missing. I suspected as much, but the help for Execute is somewhat vague. Incidentally, is _VarDump in the standard UDFs shipped with AutoIt3? It's not in the help. Those might be useful permanent additions to the standard UDFs and help file, maybe in Misc.au3. My UDFs: ExitCodes Link to comment Share on other sites More sharing options...
jchd Posted April 13, 2011 Share Posted April 13, 2011 It's a classic found in the example scripts forum (search is your friend) but not in any std UDF. I believe I modified it long ago so the version(s) you're gonna find are probably slightly different, but only cosmetic as I recall.

Mat Posted April 13, 2011 Share Posted April 13, 2011 For Au3Int I had a similar problem, with the addition that since the user could define whatever variables they like I needed to obfuscate the variable names... I made this function as a workaround. It uses a similar idea (based on execute) but assigns the variable name randomly, which means 1) Obfuscator doesn't mess up the name and 2) People won't accidentally assign a value to a global with the same name. expandcollapse popupLocal $a1[5] = [1, 2, 3, 4, 5] Local $a2[5][2] = [[1, 2], [3, 4], [$a1, 46], [7, 8], [9, 10]] _Au3Int_PrintVar($a2) Func _Au3Int_PrintVar($vVar, $sPre = "") If IsArray($vVar) Then Local $sRandomVarName = Hex(Random(1000, 10000, 1)) Assign($sRandomVarName, $vVar, 1) ConsoleWrite($sPre & "=> Array") For $i = 1 To UBound($vVar, 0) ConsoleWrite("[" & UBound($vVar, $i) & "]") Next ConsoleWrite(@CRLF) Local $a[UBound(Eval($sRandomVarName), 0) + 1], $iBnd = UBound(Eval($sRandomVarName), 0) For $i = 0 To $iBnd $a[$i] = 0 Next $i = StringLen($sPre) $sPre = " " For $i = $i To -2 Step -1 $sPre &= " " Next $a[$iBnd] = -1 While 1 $a[$iBnd] += 1 For $i = $iBnd To 1 Step -1 If $a[$i] = UBound(Eval($sRandomVarName), $i) Then $a[$i] = 0 If $i = 1 Then ExitLoop 2 $a[$i - 1] += 1 EndIf Next Local $sTmp = "" For $i = 1 To $iBnd $sTmp &= "[" & $a[$i] & "]" Next _Au3Int_PrintVar(Execute("$" & $sRandomVarName & $sTmp), $sPre & " " & $sTmp & " ") WEnd Return ElseIf IsString($vVar) Then $vVar = """" & $vVar & """" EndIf ConsoleWrite($sPre & "=> " & $vVar & @CRLF) EndFunc ;==>_Au3Int_PrintVar AutoIt Project Listing Link to comment Share on other sites More sharing options...
