Is there a easy way to parse string to array?

Recommended Posts

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]
         Next
    Next
    Return $res
EndFunc

Here is my small contribution :

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]

      Hi,
      I'm looking for a way to take a number value from a Row2 of a 2D array and according to this check if files that appear in rows 3-11 in the array exists.
      For example, if the number in Row2 is 5 I need to check for the files in Row 3-6 only, if it is 6 than rows 3-7 and so on.
      I thought on using a FOR loop but I have very little experience with those.
      Can you suggest the best way to do what I need?
      BTW, the files in Rows 3-11 will usually have blank value for any row above the number in Row2 (e.g. Row2 = 5 so Rows3-6 will have values but 8-11 be empty), The values I need are in Column 1 of the array, the name of the key from the INI file that the array was created from is in Column 0.
      Full Example:
      Row2 of Array:
      Col0 = Games# - Col1 = 5
      Rows3-6
      Col0 = Exe2 - Col1 = Path To File
      Col0 = Exe3 - Col1 = Path To File
      Col0 = Exe4 - Col1 = Path To File
      Col0 = Exe5 - Col1 = Path To File
      I need that if Row2 is 5 to check these above for rows if the file exists, if it was 6 then the next row as well and so on up until number 10 in Row2 as it can't go above 10.
      So basically for whatever number in Row2 from 2-10 need to check 1-9 rows from 3-11 to see if the files in Col1 exists and if any of them don't exist it should call a function that shows an error message.
      I'm pretty sure I have the first line of the for look correct:
      For $i = 1 To $aAIO[2][1] Just not sure how to continue from there, also not sure if $i should be equal 1 or 2.
      Help will be appreciated.

      Hello,
      I'm trying to get data from twitter to an array and so far I found an Twitter UDF whish lookes very intresting but couldn't get it to work.
      It lookes not supported any more(2010) and buggy when i read all te replies.
      More around this subject (autoit and twitter) i couldn't find on this forum.
      Is there sombody who know's a good way to get live data from twitter to an array inside autoit?
      (I kinda doubt that this isn't tackled before)
      In the end I was hoping to get all tweets from date to date from an specific subject inside a 2D array to work whit.

      it needs to check server 1. then run function 1 or function 2 after what i selected in the checkbox.
      once that function is done it moves to the next one, until it has been trough all 5 
       
      iv'e tried using while loops with different while $i equals to something but then i manualy need to go in and edit the script every time.

      Hi everyone, 
      I'm currently writing a script that allow me to list all currently installed software on a computer but some of the are listed in the HKLM64 hive of the registry whereas 95% of all others are in the HKLM "normal" one.
      Thing is, I'd like to combine these two reg key into one single ListView item.
      Here's my code so far, knowing that it's working on both cases (changing to HKLM64 or HKLM short)
      Thanks in advance for the help

      Hi everyone, I'm at best a noobie.  I have read through the Array helps, and specifically the 2D array help file, and I'm struggling to get my code working.
      I have an array that is read from a file, thats working great.  I'm trying to do some math on the array, so I can find the largest, average, lowest, day over day change %, etc.
      The array read working fine, I get 43 lines, line 0 is 44, and then I get data that looks like
      0519 $10,000
      0520 $10,001
      0521 $10,002
      The data in this array is a single 1D array, breaking it out into 2 columns so I can do the math is what I can get to happen.  
      How do I reference the array to store this data?  Second, how do I assign this data to the appropriate row/column?
      Thanks in advance.
