Regex Testing For Highest Version Number in Dir Listing

Recommended Posts

gruntydatsun

Hey guys,

I'm getting a directory listing of folders within a folder on the network with _FileListToArray then I need to search through that list and determine which folder is named with the largest version number. 

The problem I'm having is with weeding out folders that are not named in the version numbering naming convention.   That naming convention is:   must only contain numbers and full stops like 1.2.3 or 2.8.14 and there can be two or more sets of numbers  eg 1.2  or 1.2.3 or 1.2.3.4 etc.  

Would someone please tip me off on whats wrong with my regex?

#include <array.au3>

Local $array = ["1.7.8","1.7.9","1Goat.Eating.Pastrami.2.3","128","1.7.10","TriggeredLefty.69"]

for $x = 0 to Ubound($array)-1
    if StringRegExp($array[$x],"[\d\.^\w]+") = 1 Then   ;<<<<< y u no work!!!
        $aThisEl = StringSplit($array[$x],".",2)
        _ArrayDisplay($aThisEl,"This version")
    EndIf
Next

    If @extended = 0 then  _ArrayDisplay(stringsplit($array[$i] , "." , 2))
next

Hi.

Others reading this thread might not be familiar with _versioncompare() ... ;)

 

#include <Misc.au3>

Local $array = ["1.7.8", "1.7.9", "1Goat.Eating.Pastrami.2.3", "128", "1.7.10", "TriggeredLefty.69", "14.23.8.is that correct?", "And that:2.3.4 something"]
Local $aRes
Local $MaxVer = False
For $x = 0 To UBound($array) - 1
    $aRes = StringRegExp($array[$x], "^\d+(?:\.\d+)+$", 3)
    If Not @error Then
        ConsoleWrite("Version found: " & $aRes[0] & " in " & $array[$x] & @LF)
        If $MaxVer Then
            If _VersionCompare($aRes[0], $MaxVer) = 1 Then
                $MaxVer = $aRes[0]
                ConsoleWrite("Higher version found: " & $MaxVer & @CRLF)
            EndIf
        Else
            $MaxVer = $aRes[0]
            ConsoleWrite("First Version found: " & $MaxVer & @CRLF)
        EndIf
    EndIf
Next

ConsoleWrite("------------------------------------------" & @CRLF)

if $MaxVer Then
    ConsoleWrite("higest version found: " & $MaxVer & @CRLF)
Else
    ConsoleWrite("no version found at all!" & @CRLF)
EndIf
