Separating items within an array

5 posts in this topic

Okay, I have a folder with the following files in it:

testaudio.mp3

testaudio02.mp3

testaudio02.mp3wrec

testaudio03.mp3

testaudio03.mp3wrec

As you can see a couple of them have the "mp3wrec" file extension. I've used _FileListToArray to add all those files to an array called $mp3List. What I'm wanting to do is sort the mp3wrec files from the regular mp3s (my script only wants to deal with the regular mp3s). The only way I'd know how to do this is to do a StringSplit on each index in the array, using the "." as the delimiter, thus creating another array and a whole lot more work. But can anybody see an easier way to separate the mp3s from the mp3wrecs? I'm having some trouble using StringSplit within an array. And usually when I'm having trouble with something it's because what I'm trying to do can usually be done in about two lines of code instead of a whole function. :)

Build a query in StringRegExp() to only find files that end in ".mp3". A simpler method would be to StringRight($string,4) and only do something if the result is ".mp3". A StringRight($string,4) on a .mp3wrec file would return "wrec".

If StringRight($String, 4) = "wrec" then; compares last 4 digits to "wreck"

Or maybe

if not StringInStr(StringRight($String,4),".") then;checks for "." in the last 4 characters of filename

How about using FileListToArray first to sort out the .mp3's from the .mp3wrec's?

Something like:

$a_UserFileList = _FileListToArray($s_Directory, "*.mp3", 1)

then reading each file into an array using _FileListToArray like:

For $x = 1 to UserFileList[0]

_FileReadToArray($s_Directory & $a_UserFileList[$x], $a_UserFile[$x])

Next

Don't forget to put a "\" at the end of the $s_Directory variable.

Once you've done your business with the .mp3's, you can do the same for the .mp3wrec's.

Edit: Fixed typo

I've been doing some mucking around of my own and came out with something similar to what PartyPooper suggested. Except I've used FileFindFirstFile to add the mp3wrecs to an array one by one. This adds "testaudio01.mp3wrec" and "testaudio02.mp3wrec" to an array:

Func LogIt($LogText)
    ConsoleWrite(@MDAY & "/" & @MON & "/" & @YEAR & " " & @HOUR & ":" & @MIN & " " & @UserName & " " & @ComputerName & ": " & $LogText & @CRLF)
EndFunc

Func StartFunc($Function)
    ConsoleWrite(">" & @MDAY & "/" & @MON & "/" & @YEAR & " " & @HOUR & ":" & @MIN & " " & @UserName & " " & @ComputerName & ": " & $Function & @CRLF)
EndFunc

Func CountWrecs()
    StartFunc("CountWrecs()")   
    $CountWrec = FileFindFirstFile($AudioDir & "*.mp3wrec")
    If $CountWrec = -1 Then
        LogIt("No mp3wrecs found")
        ; go to next function
    Else
        $WrecArray = _ArrayCreate($WrecArray)
        While 1
            $Wrec = FileFindNextFile($CountWrec)
            If @error Then ExitLoop
            $WrecCountTotal = $WrecCountTotal + 1
            _ArrayAdd($WrecArray, $Wrec)
            LogIt($Wrec & " added to $WrecArray")
        WEnd
        LogIt("Total mp3wrecs found: " & $WrecCountTotal)
        _ArrayDisplay($WrecArray)
        FileClose($CountWrec)
        FileClose($Wrec)
        ;$CountWrecsDone = 1
        SearchWrecArray()
    EndIf
EndFunc

For example, I am trying to search each item in the array to see if it contains the string $MP3Name[1], which in this case is "testaudio01". However it's not finding it, even though there actually is an item in the array named "testaudio01.mp3wrec". My little LogIt function says this:

04/07/2008 11:14 taylorsu JD37394: Searching testaudio01.mp3wrec for string testaudio01

04/07/2008 11:14 taylorsu JD37394: String testaudio01 not found in testaudio01.mp3wrec

04/07/2008 11:14 taylorsu JD37394: Searching testaudio02.mp3wrec for string testaudio01

04/07/2008 11:14 taylorsu JD37394: String testaudio01 not found in testaudio02.mp3wrec

I'm not sure whether it's a problem with my StringInStr or the For $i =. This is the first time I've used a For $i =, am I doing it the right way?

EDIT: Holy crap I had the parameters in StringInStr around the wrong way. Incredible. And I've done TONS of StringInStr's in the past too. Well, I'm an idiot.
