StringExplode behavior after upgrading from 3.3.10.2 to 3.3.12.0

7 posts in this topic

Hello, have only just upgraded Autoit from 3.3.10.2 to 3.3.12.0 & now my scripts that use _StringExplode on a delimiter = @CRLF insert the delimiter as an element in the array, the script below demonstrates this.

Text file is

1,2
3,4
4,5
6,7
8,9
9,0

The _ArrayDisplay (3.3.12.0) is:

[0] 1,2
[1]
[2] 3,4
[3]
[4] 4,5
[5]
[6] 6,7
[7]
[8] 8,9
[9]
[10] 9,0
[11]
[12]

The _ArrayDisplay (3.3.10.2) is:

[0] 1,2
[1] 3,4
[2] 4,5
[3] 6,7
[4] 8,9
[5] 9,0
[6]

#Include <File.au3>
#Include <Array.au3>
#include <String.au3>
$h = FileOpen("c:\test\stringexplode.txt",$FO_READ)

;stringexplode.txt - below
#cs CRLF at end of eachline
1,2
3,4
4,5
6,7
8,9
9,0

#ce

$sTest = FileRead($h)
FileClose($h)
$aTest = _StringExplode($sTest,@CRLF)
_ArrayDisplay($aTest);The array includes the delimiter as an element, this behavior is different to autoit 3.3.10.2, what am I missing??

I did check "Array UDF - Script Breaking Changes" but didn't find a reference to this.

I have attached the original text file for convenience

Appreciate any insight, thank you

one or the other, and with a -1 gets rid of the empty

$aTest = _StringExplode($sTest, @LF , -1)

or

$aTest = _StringExplode($sTest,@CR , -1)

Thanks, I did test your proposal & certainly it did remove the @CRLF as an array element, the only issue I have is that after I use "FileWriteLine" to recreate the original text file(see script below), viewed using Notepad ++ I see additional LF(if delimiter = @CR), this is an issue for my database of text files with CRLF @ the end of each line of text.

Here is my demo script to illustrate the issue:

#Include <File.au3>
#Include <Array.au3>
#include <String.au3>
$h = FileOpen("c:\test\stringexplode.txt",$FO_READ)

;stringexplode.txt - below
#cs CRLF at end of eachline
1,2
3,4
4,5
6,7
8,9
9,0

#ce

$sTest = FileRead($h)
FileClose($h)
$aTest = _StringExplode($sTest,@CR)
_ArrayDisplay($aTest);The array includes the delimiter, this behavior is different to autoit 3.3.10.2, what am I missing??

;Rewrite the file to a new text file
$h = FileOpen("c:\test\stringexplode1.txt",$FO_OVERWRITE+$FO_CREATEPATH)
For $i = 0 to UBound($aTest)-1
    FileWriteLine($h,$aTest[$i])
Next
FileClose($h)
$h = FileOpen("c:\test\stringexplode1.txt",$FO_READ)
$sTest = FileRead($h)
ConsoleWrite("! $sTest" & @CRLF)
ConsoleWrite($sTest & @CRLF);viewed in console window the read file has an empty line between lines with text, in notepad++ u can see an extra LF(view=>Show Symbol=>'Show End Of Line' characters)

Any thoughts?? Thank you

Looking at the function _StringExplode in String.au3 in the include directory you will see  

Return StringSplit($sString, $sDelimiter, $STR_NOCOUNT)

where $STR_NOCOUNT = 2

Previous versions of AutoIt has

Return StringSplit($sString, $sDelimiter, 3)

where 3 = 1+ 2 =  $STR_ENTIRESPLIT (1) +  $STR_NOCOUNT (2)

My advice is to use StringSplit($sTest, @CRLF, 3) in your script instead of _StringExplode($sTest,@CR)

This appears to be an introduced bug into the  _StringExplode function.

The extra lines are introduced because  each character in the delimiter string in _StringExplode  will mark where to split the string.   And @CRLF is two characters.

Thanks Malkey, your advise worked like a charm, I really appreaciate it....

My advice is to use StringSplit($sTest, @CRLF, 3) in your script instead of _StringExplode($sTest,@CR)

This appears to be an introduced bug into the  _StringExplode function.
 

 

Melba we look forward to the return of _StringExplode less it's aberrant behavior..lol

Sorry about that. Literally have no idea how that happened.

Edit: I introduced the bug back in rev 9497 on 04 January 2014 03:08:00. So my apologies. By the looks of the time it was late!

      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.
      Local $aFoo = [0,1,2,3,4,5,6,7,9,10,11,12,13,14,15,16,19,20,23,24,26,30,35,39,40,41] Local $aBar = [0,1,5,6,7,8,9,10,11,12,13,14,17,18,19,21,24,25,26,27,34,35,38,40] ParallelExponetialSearch($aFoo, $aBar) ; Compares two lists - returning positive matches. Each input array must be unique (individually) and in alphabetical order. Func ParallelExponetialSearch($aFoo, $aBar) Local $sFind, _ $iMin_F = -1, $iMax_F = UBound($aFoo) -1, $Lo_F = $iMin_F, $Hi_F, _ $iMin_B = -1, $iMax_B = UBound($aBar) -1, $Lo_B = $iMin_B, $Hi_B While $iMin_F < $iMax_F And $iMin_B < $iMax_B ; Toggle Arrays - Which array has most untested elements? This is the one we want to search next, ; so we can bypass more comparisons because (in theory) mismatches have a greater chance of being skipped. If $iMax_F - $iMin_F >= $iMax_B - $iMin_B Then ; $aFoo has more (or an equal number of) untested elements $Hi_F = $iMax_F $iMin_B += 1 $sFind = $aBar[$iMin_B] While $Lo_F < $Hi_F ; search $aFoo For $i = 0 To Floor(Log($Hi_F - $Lo_F) / Log(2)) $Lo_F = $iMin_F + 2^$i If $aFoo[$Lo_F] = $sFind Then $iMin_F = $Lo_F ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $Lo_F & "] = $aBar[" & $iMin_B & "]" & @LF) ExitLoop 2 ElseIf $aFoo[$Lo_F] > $sFind Then $Hi_F = $Lo_F -1 $iMin_F += Floor(2^($i -1)) $Lo_F = $iMin_F ContinueLoop 2 EndIf Next $iMin_F = $Lo_F ; minimum increment is one WEnd Else ; $aBar has more untested elements $Hi_B = $iMax_B $iMin_F += 1 $sFind = $aFoo[$iMin_F] While $Lo_B < $Hi_B ; search $aBar For $i = 0 To Floor(Log($Hi_B - $Lo_B) / Log(2)) $Lo_B = $iMin_B + 2^$i If $aBar[$Lo_B] = $sFind Then $iMin_B = $Lo_B ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $iMin_F & "] = $aBar[" & $Lo_B & "]" & @LF) ExitLoop 2 ElseIf $aBar[$Lo_B] > $sFind Then $Hi_B = $Lo_B -1 $iMin_B += Floor(2^($i -1)) $Lo_B = $iMin_B ContinueLoop 2 EndIf Next $iMin_B = $Lo_B ; minimum increment is one WEnd EndIf WEnd EndFunc ;==> ParallelExponetialSearch I hope this will be useful to someone. I believe it deserved a thread of its own!

      Afternoon!
      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.
      Thanks!

      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 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.

      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!
