I've just written a small script that compares two strings and returns the similarity of those two in %. I know of StringCompare, but I want to get a percentage and I also want to get in touch with Autoit.

Compiling doesn't cause any problems, but actually running it does. In line 20 it has a problem with the index and says "Subscript used on non-accessible variable". What's causing that problem, and how can I solve it? Thanks! And sorry for my ugly style

Try this:
 

#include <MsgBoxConstants.au3>

Global $sTitle = "Similarity"
Global $tTextA = InputBox($sTitle, "Data 1: ")
Global $tTextB = InputBox($sTitle, "Data 2: ")
If $tTextA = $tTextB Then Exit MsgBox($MB_TOPMOST, $sTitle, "Smiler: 100%")
Local $nStringLenTextA = StringLen($tTextA)
Local $nStringLenTextB = StringLen($tTextB)
$tTextA = StringReplace($tTextA, " " & " ", " ")
Local $cSpit = StringInStr($tTextA, " ") ? " " : ""
Local $sSpitA = StringSplit($tTextA, $cSpit)
Local $Smiler = 0, $px = UBound($sSpitA)
For $i = 1 To $px - 1
    If StringInStr($tTextB, $sSpitA[$i]) Then $Smiler += 1
    ConsoleWrite($sSpitA[$i] & " : " & $tTextB & @CRLF)
Next
ConsoleWrite($px & @CRLF)
If $px > 3 Then $px -= 1
Local $SmilerPercent = ($Smiler * 100) / ($px - 1);$nStringLenTextB
If $SmilerPercent > 199 Then $SmilerPercent = 99
MsgBox($MB_TOPMOST, $sTitle, "Smiler: " & $SmilerPercent & "%")

Exit

Wicked_Caty,

$a and $b are NOT arrays.  Try it using stringmid like this...

#include <MsgBoxConstants.au3>

$title = "Similarity"
;~ $a = InputBox($title, "Data 1")
;~ $b = InputBox($title, "Data 2")
local $a = 'abcd'

local $b = 'abce'

$n = 0
$la = StringLen($a)
$lb = StringLen($b)
$lc = ($la + $lb) / 2

If $la > $lb Then
   $l = $la
ElseIf $lb > $la Then
   $l = $lb

Else
   $l = $lc

EndIf



For $i = 1 To $l
    ConsoleWrite($i & @CRLF)
   If (stringmid($a,$i,1) = stringmid($b,$i,1)) Then
      $n = $n + 1
   EndIf

Next

$p = $n / $l * 100

MsgBox($MB_TOPMOST, $title, $a & @CRLF & $b & @CRLF & $title & ":" & @TAB & $p)

Exit

note: only strings of equal length tested...input supplied as strings, not user input

edit: also your loop should start at position "1" for strings

The problem is you're trying to use a variable that is not there.

You can solve it by ensuring you do not try to access a non existent variable.

Wicked_Caty,

Streamlined the code a bit.  If the string lengths are equal just use one or the other as the length value, no need to add them and divide by two.  I used a ternary expression to replace all of your length determination code...

#include <MsgBoxConstants.au3>

$title = "Similarity"
;~ $a = InputBox($title, "Data 1")
;~ $b = InputBox($title, "Data 2")
local $a = 'abcdf'

local $b = 'abce'



local $len_to_check = (stringlen($a) > stringlen($b)) ? stringlen($a) : stringlen($b), $p = 0, $n = 0

For $i = 1 To $len_to_check
   If (stringmid($a,$i,1) = stringmid($b,$i,1)) Then
      $n = $n + 1
   EndIf

Next

$p = $n / $len_to_check * 100

MsgBox($MB_TOPMOST, $title, $a & @CRLF & $b & @CRLF & $title & ":" & @TAB & $p)

Exit

Good Luck,

kylomas

jguinch,

I believe you refer to my unifuzz SQLite extension; start reading here, then have luck finding the actual post where the extension resides later in this same thread. The new search feature is terrible. For the matter of string comparison outside of SQLite, this post may give something to work with.

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.
Another excellent RegExp tutorial. Don't forget downloading your copy of up-to-date pcretest.exe and pcregrep.exe here
RegExp tutorial: enough to get started
PCRE v8.33 regexp documentation latest available release and currently implemented in AutoIt beta.

SQLitespeed is another feature-rich premier SQLite manager (includes import/export). Well worth a try.
SQLite Expert (freeware Personal Edition or payware Pro version) is a very useful SQLite database manager.
An excellent eBook covering almost every aspect of SQLite3: a must-read for anyone doing serious work.
SQL tutorial (covers "generic" SQL, but most of it applies to SQLite as well)
A work-in-progress SQLite3 tutorial. Don't miss other LxyzTHW pages!

According to the Levenshtein algorithm (https://en.wikibooks.org/wiki/Algorithm_Implementation/Strings/Levenshtein_distance#VBScript), from the VBS code :

$s1 = "My String 1"
$s2 = "My String 2 !"



Local $Levenshtein = Levenshtein($s1, $s2)

Local $iMaxLen = StringLen (  StringLen($s1) > StringLen($s2) ? $s1 : $s2 )
Local $percent = Round(($iMaxLen - $Levenshtein) * 100 / $iMaxLen, 2)

ConsoleWrite($percent & "%")


Func levenshtein( $a, $b )
    Local $i, $j, $cost, $d[1], $min1, $min2, $min3

    If StringLen( $a ) = 0 Then Return StringLen( $b )
    If StringLen( $b ) = 0 Then Return StringLen( $a )

    ReDim $d[ StringLen( $a ) + 1][ StringLen( $b ) + 1]

    For $i = 0 To StringLen( $a )
        $d[$i][0] = $i
    Next

    For $j = 0 To StringLen( $b )
        $d[ 0][$j] = $j
    Next

    For $i = 1 To StringLen( $a )
        For $j = 1 To StringLen( $b )
            $cost =  ( StringMid($a, $i, 1) = StringMid($b, $j, 1) ? 0 : 1)

            $min1 = $d[$i - 1][$j] + 1
            $min2 = $d[$i][$j - 1] + 1
            $min3 = $d[$i - 1][$j - 1] + $cost

            If $min1 <= $min2 And $min1 <= $min3 Then
                $d[$i][$j] = $min1
            ElseIf $min2 <= $min1 And $min2 <= $min3 Then
                $d[$i][$j] = $min2
            Else
                $d[$i][$j] = $min3
            EndIf
        Next
    Next

    Return $d[StringLen( $a )][StringLen( $b )]
EndFunc

      I have a string containing the full path of an executable and an array of executables without their paths. I am trying to compare the string to the list in the array and if a match is found, remove it from the array. The entry get removed from the array successfully, and after checking its return result, uses it to update the ubound if it succeeded, but it doesn't want to update to the new value. Any ideas what I am doing wrong? It acts like it is read-only.
      #include <Array.au3> #include <File.au3> Local $sApp_Exe = "F:\App\Nextcloud\nextcloud.exe" Local $aWaitForEXEX = [3, "Nextcloud.exe", "nextcloudcmd.exe", "QtWebEngineProcess.exe"] For $h = 1 To $aWaitForEXEX[0] If StringInStr($sApp_Exe, $aWaitForEXEX[$h]) <> 0 Then $iRet = _ArrayDelete($aWaitForEXEX, $h) If $iRet <> -1 Then $aWaitForEXEX[0] = $iRet ;this line doesn't work. $aWaitForEXEX[0] doesn't update and shortly gives Error: Array variable has incorrect number of subscripts or subscript dimension range exceeded.: _ArrayDisplay($aWaitForEXEX) EndIf Next

      I have a dataset like this, (a strubg)
      Username: User1 Type: Admin RegDate: 1999 Username: User2 Type: User RegDate: 2000 How to make a 2 dimensional array that I can display with _ArrayDisplay?
      This would be a perfect 2D array to represent my data:
      Username           Tpye RegDate User1              Admin 1999 User2              User 2000   If you run this Powershell this powershell command, you can get this dataset that I am talking about:
      Get-LocalUser | Select * With this code you can try it to read into a string:
      #include <GuiConstantsEx.au3> #include <WindowsConstants.au3> #include "GUIListViewEx.au3" #include <Array.au3> ; Just for display in example #RequireAdmin #Region ;**** Directives created by AutoIt3Wrapper_GUI **** #AutoIt3Wrapper_UseX64=y #EndRegion $sCommand = "powershell.exe Get-LocalUser | Select *" Local $iPid = Run($sCommand, @WorkingDir , @SW_SHOW , $STDOUT_CHILD) ProcessWaitClose($iPid) Local $sOutput = StdoutRead($iPID) ConsoleWrite($sOutput) How can I correctly split $sOutput into a 2D array (with the above mentioned layout) that I can display and I work with?

      Are there any way to use the $aOutput variable like in PowerShell:
