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], ",", ",")

      Hello,
      at first: i'm new here, so please forgive me my mistakes, and show them to me, just that i can learn to do better in the future.
      Now to my Problem: i have an excel sheet, where i just need some columns for further actions, but i have no idea how to add single columns to a new array.
      I found the following code(the one i just added as a file) from 'water' in this forum, but i wont get how i could add multiple columns into a new array.
      The biggest problem in my situation is that i dont know the count of the rows i need for the array, i just got a fix number of rows, which is 4.
       
      Hope you can help me, and sry again for this 'unlucky illustration'.
       
      btw: how can i add code shown as code here, instead of posting it as a attached file?.

      Haven't had much time to code recently. However the following thread inspired me.
      The debate about linear, parallel and binary search methods was rather interesting and, in an attempt to be diplomatic, I decided to combine @jchd's suggestion with @LarsJ's binary search example. I decided that the binary search algorithm required modification to make it more linear. As usual, 'if you invent something, it probably already exists and if it already exists, it exists for a reason'. My first attempt was not all that good. The code worked but was really a mess. I blame peer pressure (to post an example of a parallel search method).  I will delete that old code in due course.
      With a little memory jogging and a glance at the help file, the solution turned out to be quite easy: I just needed a better understanding of Euler. Further modification will be needed to work with more complicated unicode strings. The output could be returned as an array or a delimitered string. I'm not so interested in those details. I'm just going to post the algorithm for now and anyone, who wants to, can modify it to suit their needs. Both arrays must contain at least 1 element.

      I have a requirement to return both a string and an array from a function so as a result I put them both into an array and returned that.  I can access them in their entirety after returning them but then I can't seem to access the array elements after this.  Should I be able to or is there a prettier way?
      #include <Array.au3> ;Memory info returned as a string and an array $memoryInfo = _getMemoryInfo() msgbox(0,"Memory Info",$memoryInfo[0]) _ArrayDisplay($memoryInfo[1],"Memory as an Array") Local $newArray[7] $memoryInfo[1] = $newArray msgbox(0,"Test element",$newArray[0]) _ArrayDisplay($newArray) Func _getMemoryInfo() Local $newArray[7] Local $array = MemGetStats() $newArray[0] = $array[0] ;% of memory in use $newArray[1] = Round($array[1]/1024 * 0.001,2) ;Total physical RAM $newArray[2] = Round($array[2]/1024 * 0.001,2) ;Availaible physical RAM $newArray[3] = Round($array[3]/1024 * 0.001,2) ;Total pagefile $newArray[4] = Round($array[4]/1024 * 0.001,2) ;Available pagefile $newArray[5] = Round($array[5]/1024 * 0.001,2) ;Total virtual $newArray[6] = Round($array[6]/1024 * 0.001,2) ;Available virtual $memoryUsage = $newArray[1] - $newarray[2] $pagefileUsage = $newArray[3] - $newarray[4] ;Output/Return Local $returnArray[2] $returnArray[0] = "Memory: " & $memoryUsage & " GB/" & $newArray[1] & " GB " & @CRLF & "Pagefile: " & $pagefileUsage & " GB/" & $newArray[3] & " GB " $returnArray[1] = $newArray return $returnArray EndFunc A bit messy but hopefully it's understandable what I'm trying to achieve.

      I am having difficulties getting updated results from GUICtrlCreateInput. I wrote a small script to demonstrate what I am trying to do.
      This script reads a text file into an array and displays the Name and Number from the text file.
      The user can check a name and change the number, and the results are displayed in _ArrayDisplay.
      Only the Checked names are displayed in their original position. This is necessary for future
      plumbing.
      The problem with this script is the original number is returned, not the changed number. I cannot
      figure out how to get the updated number to be displayed.

I need the modified number to be displayed.
      Thanks in advance for any assistance!

      I am working on a Video Player Test Script. I am reading a text file into a 3d array to be displayed in a GUI.
      Array Content:
      [x][0]FileName.mp4
      [x][1]UsageCount -> Up to a 4 digit number
      [x][2]EnableUsageCount (True/False)
      In the GUI the user can check the filename box, edit the number of usages and check EnableUsageCount to turn on the UsageCount control using the UsageCount number for the maximum number of plays.
      To make this easier to deal with I have removed the EnableUsageCount section, and am just concentrating on getting a method to put the edited (or unchanged) UsageCount in the array. Currently nothing is read into the array, due to my using the wrong method in the Case statement.
      Here are code snippets of what I am trying to do:
      ; Snippets from script ; I read the text file at the bottom and put the .mp4 filenames in $aManifest[x][0] and UsageCount in $aManifest[x][1] ; Then I create a GUI to display the .mp4 filenames with checkboxes and the UsageCount to the right. UsageCount is editable by the user. ; If the filename is checked, I want to read the filename into $aCheckedVideos[x][0] and the updated UsageCount in $aCheckedVideos[x][1] ; The GUICtrlRead($aVideoName[$i]) with Case $GUI_CHECKED & UNCHECKED works for the checkboxes ; This section puts the filenames in the GUI with a checkbox For $i = 0 to $iMMCount Step 1 $sMP4Text = $aManifest[$i][0] $iMP4Length = StringLen($sMP4Text) $aVideoName[$i] = GUICtrlCreateCheckbox($sMP4Text,$iLeft, $iTop) $iTop += 30 Next ; This section reads numbers from the Manifest array, and I want to be able to change the number and have them saved. ; So the Case $GUI_CHECKED & UNCHECKED won't work here, and I can't figure out what I should be doing here. For $i = 0 to $iMMCount Step 1 $sUsageText = $aManifest[$i][1] $aUsageCount[$i] = GUICtrlCreateInput($sUsageText,$iLeft, $iTop, 50,18, $GUI_DOCKAUTO) GUICtrlSetPos($aUsageCount[$i],200) $iTop += 30 Next While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $idCloseGUI For $i = 0 To $iMMNewCount Step 1 Switch GUICtrlRead($aVideoName[$i]) Case $GUI_CHECKED $aCheckedVideos[$i][0] = $aManifest[$i][0] ; If checked, I put the results into a two D array Case $GUI_UNCHECKED ; where Video Name is $aCheckedVideos[x][0] EndSwitch Switch GUICtrlRead($aUsageCounter[$i]) Case $GUI_CHECKED $aCheckedVideos[$i][1] = $aUsageCount[$i] ;I want to put the text (numbers) in $aCheckedVideos[x][1] Case $GUI_UNCHECKED ;but what is returned is blank, probably due to EndSwitch ; $GUI_CHECKED being the wrong thing. Next ExitLoop EndSwitch WEnd ;The txt file I'm reading has the following: ;~ /** Title #1: Big Buck Bunny 1080p **/ ;~ "Name": "Big Buck Bunny", ;~ "URI": "..\\MediaFiles\\bbb_1080_60s.mp4", ;~ "UsageCount": 9999, ;~ "URI": "..\\MediaFiles\\bbb_1080_60s_enc1.mp4", ;~ "UsageCount": 45, ;~ "URI": "..\\MediaFiles\\bbb_1080_60s_enc1.mp4", ;~ "UsageCount": 2, ;~ /** Title #2: Tears of Steel 4K **/ ;~ "Name": "Tears of Steel 4K", ;~ "URI": "..\\MediaFiles\\tos_4K_60s_HEVC.mp4", ;~ "UsageCount": 9876, ;~ "URI": "..\\MediaFiles\\tos_4K_60s_HEVC_enc2.mp4", ;~ "UsageCount": 0, ;~ "URI": "..\\MediaFiles\\tos_4K_60s_HEVC_enc2.mp4", ;~ "UsageCount": 5, I am certain that the section
                          Switch GUICtrlRead($aUsageCounter[$i])
                              Case $GUI_CHECKED
                                  $aCheckedVideos[$i][1] = $aUsageCount[$i]    ;I want to put the text (numbers) in $aCheckedVideos[x][1]
                              Case $GUI_UNCHECKED                                ;but what is returned is blank, probably due to
                          EndSwitch                                            ; $GUI_CHECKED being the wrong thing.

      is wrong, and this is what I am looking for help with. Instead of $GUI_CHECKED what should I be looking for?
      The worst part of this is I had this working late last night, and then lost my changes and cannot for the life of me remember how I had this working.
      Help is truly appreciated!
