Is there a easy way to parse string to array?

16 posts in this topic

Hi everybody

I need to read a multidimensional array, declared as a string, written in a ini file.

Like this:

//settings.ini
[Main]
areas=[[0,10,50,50],[500,560,50,50]]

When i read the value with IniRead, it's a string.
Is there an easy way to convert that to valid arrays?

 

Thanks

just for fun.

#include <Array.au3>
Local $sString = "[[0,10,50,50],[500,560,50,50]]"




Local $aArray = _Make2Array($sString)


_ArrayDisplay($aArray)

Func _Make2Array($sString)
    Local $aReg = StringRegExp($sString, "\d{1,}", 3)
    Local $aArray[2][UBound($aReg) / 2]
    For $i = 0 To (UBound($aReg) - 1) / 2
        $aArray[0][$i] = $aReg[($i)]
        $aArray[1][$i] = $aReg[($i) + (UBound($aReg)) / 2]
    Next
    Return $aArray
EndFunc   ;==>_Make2Array

Quick n dirty...not bad.  My only complaint...it's too tailored for this particular scenario.  
There is nothing wrong with making a very, very specific function...but the modular mindset in me is twitching.

My 2 cents, for the concept and w/o error checking

#include <Array.au3>

Local $sString = "[[0,10,50,50],[500,560,50,50]]"

Local $aArray = _Make2Array($sString)
_ArrayDisplay($aArray)


Func _Make2Array($s)
    $s = StringRegExpReplace($s, '[\[\]]{2}', "")
    Local $s1 = StringSplit($s, "],[", 1), $s2
    StringReplace($s1[1], ",", ",")
    Local $res[$s1[0]][@extended+1]
    For $i = 1 to $s1[0]
         $s2 = StringSplit($s1[$i], ",")
         For $j = 1 to $s2[0]
              $res[$i-1][$j-1] = $s2[$j]
         Next
    Next
    Return $res
EndFunc

Edit
Hehe, JO was right about StringSplit, but I don't know a one-liner regex able to return a 2D array  :)

Not with the current PCRE implementation, sadly. Nor with the current ReDim which (sadly again) doesn't allow various dimension combinations. Hence pedestrian solutions only.

You can get around various dimensional combinations by using array of arrays, rather than just array of strings/integers.

#include <Array.au3>
Local $sString = "[[0,10,50,50],[500,560,50,50]]"
$a = StringRegExp($sString,"\[([\d,]+)\]",3)
For $i = 0 To UBound($a)-1
    $a[$i] = StringSplit($a[$i],",",2)
    _ArrayDisplay($a[$i])
Next

Local $sString = "[[0,10,50,50],[560,50,50]]"
$a = StringRegExp($sString,"\[([\d,]+)\]",3)
For $i = 0 To UBound($a)-1
    $a[$i] = StringSplit($a[$i],",",2)
    _ArrayDisplay($a[$i])
Next

Does it matter if the array is 2D, as long you read them out where you need them?

$count = 0
$sOut = ""

Local $sString = "[[0,10,50,50],[500,560,50,50]]"

$aString = stringsplit(stringreplace(stringreplace($sString , "]" , "") , "[" , "") , "," , 2)

For $i = 0 to ubound($aString) - 1
    $count += 1
    $sOut &= $aString[$i] & @TAB
    If $count = (ubound($aString) / 2) Then $sOut &= @LF
Next

msgbox(0, '' , $sOut)

This modified mikell's example allows for a 2D array with varying number of columns in rows.

#include <Array.au3>

Local $sString = '[[0,10,50,50],["L", "o", "n", "g", "e", "s", "t"],["The least","number of columns","in a row"],[500,560,50,50,5]] '
Local $aArray = _Make2ArrayEx($sString)
_ArrayDisplay($aArray)


Func _Make2ArrayEx($s)
    $s = StringRegExpReplace($s, '[\[\]]{2}', "")
    Local $s1 = StringSplit($s, "],[", 1), $s2
    StringReplace($s1[1], ",", ",")
    Local $iUB_Cols = @extended + 1
    Local $res[$s1[0]][$iUB_Cols]
    For $i = 1 To $s1[0]
        $s2 = StringSplit($s1[$i], ",")
        If $s2[0] > $iUB_Cols Then
            $iUB_Cols = $s2[0]
            ReDim $res[$s1[0]][$iUB_Cols]
        EndIf
        For $j = 1 To $s2[0]
            $res[$i - 1][$j - 1] = $s2[$j]
        Next
    Next
    Return $res
EndFunc   ;==>_Make2ArrayEx

BTW this format is very similar to a CSV is you remove the leading and trailing square brakets and consider '],[' as a line separator. This modulo spurious spacing, of course.

A variant of Malkey's variant   :)
Not sure it's faster than several Redims

#include <Array.au3>

Local $sString = '[[0,10,50,50],["L", "o", "n", "g", "e", "s", "t"],["The least","number of columns","in a row"],[500,560,50,50,5]] '

Local $aArray = _Make2Array($sString)
_ArrayDisplay($aArray)


Func _Make2Array($s)
    $s = StringRegExpReplace($s, '[\[\]]{2}', "")
    Local $s1 = StringSplit($s, "],[", 1), $s2, $n
    For $i = 1 to $s1[0]
        StringReplace($s1[$i], ",", ",")
        $n = ($n < @extended+1) ? @extended+1 : $n
    Next
    Local $res[$s1[0]][$n]
    For $i = 1 to $s1[0]
         $s2 = StringSplit($s1[$i], ",")
         For $j = 1 to $s2[0]
              $res[$i-1][$j-1] = $s2[$j]

Here is my small contribution :

#include <Array.au3>

Local $sString = '[[0,10,50,50],["L", "o", 50, "g", "e", "s", "t"],["The least","numbers of columns","in a row"],[500,560,50,50,5], ["That''s all"]] '
Local $aArray = _Make2Array($sString)
_ArrayDisplay($aArray)

Func _Make2Array($s)
    Local $aLines = StringRegExp($s, "(?<=[\[,])\s*\[(.*?)\]\s*[,\]]", 3), $iCountCols = 0
    For $i = 0 To UBound($aLines) - 1
        $aLines[$i] = StringRegExp($aLines[$i], "(?:^|,)\s*(?|'([^']*)'|""([^""]*)""|(.*?))(?=\s*(?:,|$))", 3)
        If UBound($aLines[$i]) > $iCountCols Then $iCountCols = UBound($aLines[$i])
    Next
    Local $aRet[UBound($aLines)][$iCountCols]
    For $y = 0 To UBound($aLines) - 1
        For $x = 0 To UBound($aLines[$y]) - 1
            $aRet[$y][$x] = ($aLines[$y])[$x]

    Return $aRet

      So I have a loop that keeps reading data from an array and searching it for the same value. If the value is no there it does work then adds the value to the array to prevent it from doing the same work.
      If _ArraySearch($ID,$filearray[$i]) = -1 Then Work.... _ArrayAdd($ID,$filearray[$i]) EndIf This is in a for loop hence $i
      So what is happening is the code works great for several hours. After a period of time _ArraySearch($ID,$filearray[$i]) will result in -1 even if $ID = $filearray. So it ready as if there is no data in the array. Anyone have this problem? 
       
      Also I am just running in using F5 not compiling it and running it if that makes a difference.

      I am reading a CSV file which is tab seperated as below.
      Local $aArray = FileReadToArray($file) And now, I am splitting this main array record wise so that Array contains internally another arrow to represent each row.
      For $i = 0 to (UBound($aArray) - 1) ;MsgBox(0,"",$aArray[$i]) $aArray[$i] = StringSplit(StringStripCR($aArray[$i]), Chr(9),2);Chr(9) for tab ;_ArrayDisplay($aArray[$i]) Next Afther that, _ArrayDIsplay is able to see the individual internal arrays.
      _ArrayDisplay($aArray[1]) But If I try to access the individual element of it as below.It is not showing any result.
      MsgBox(0,"",$aArray[1][1]) Any suggestion, below is the sample csv file.

      Need some help understanding why the ConsoleWrite works inside 2nd For loop but not out side. Between Audit Wiki, Help file , Forum searching (lots of code reading), and YouTube ( shout out to TutsTeach), I have not been able to find the reason why. 
      $sIniPath = "installLog.ini" ; - Get section name $iniSctionNames = IniReadSectionNames($sIniPath) ; - Get Keys and Vaules For $a = 1 to UBound($iniSctionNames) - 1 $keys = IniReadSection($sIniPath , $iniSctionNames[$a]) For $b = 1 to UBound($keys) - 1 $oldSysInfo = IniRead($sIniPath , $iniSctionNames[1], $keys[$b][0], "") $PntIPInfo = IniRead($sIniPath , $iniSctionNames[2], $keys[$b][0], "") $NewPCInfor = IniRead($sIniPath , $iniSctionNames[3], $keys[$b][0], "") ;ConsoleWrite($oldSysInfo & @LF) Next ;ConsoleWrite($oldSysInfo & @LF) Next ConsoleWrite($oldSysInfo) My intention is to use the variables later for Listboxes. Any explanation, forum post links or whatever would help. Sorry also very very new to Autoit.
