I had a hard time finding a regexp to find them all!

[EDIT] Sorry, it seems that the forum formatting messed up my post. I'll try to fix it. For the moment the example doesn't work...

[EDIT2] ok now it works.

[EDIT3] added other streaming protocols in the regexp. Thanks cyberbit

This long, long function translates decimal Windows locale codes into human-readable names. I've added a wrapper to meet the Snippets guidelines.

I wrote this when I was using WMI to query the Win32_OperatingSystem for, among other things, the OS language.

Remember, these are the decimal codes, not the hex. The example returns English - United States.

The list comes from: http://msdn.microsoft.com/en-us/goglobal/bb964664.aspx

This is really jchd's code, but I have optimized it slightly. Here is the post by jchd. I thought it was so useful that it deserved to be posted here. I hope you agree with me.

    If IsArray($aArray) = 0 Or UBound($aArray, 0) > 1 Then Return SetError (1)

However, I'm not going to implement a check if the words are in a Diceware list, as there is no standard list. Besides this function only calculates bit entropy, it doesn't care about the validity of the words that's the job of a login script.

Thanks for the feedback

Universal it won't turn out, always there will be restrictions. It is necessary to solve for a concrete case.

Func _GetSeparator($sString)
    Local $d, $s
    For $x = 1 To 9 Step 2
        For $i = 1 To 31
            $s = ''
            $d = 1
            For $z = 1 To $x
                If $d Then
                    $d = 0
                Else
                    $d = 1
                EndIf
                $s &= Chr($i + $d)

Edit
I just though of something. Perhaps first converting to binary and then splitting would work (any non hex character could be used as a universal delimiter).

Well no, it's just a different format, the problem stays the same. The non-hex character might just be the data I want to keep.

I chose ___SPLIT___ because it's rather unlikely to turn up in everyday sentences. Your question is valid nonetheless and I'm intrigued by the offered solutions.

But it would be easier to just change it to ___STRING___REGEXP___SPLIT___. You could check for ___SPLIT___ in the string and in the highly unlikely case it's in there use another overly long placeholder, put a few in an array and loop over them. Chances on collisions are very small and placeholders are a much used technique in template parsers, see the Wiki markup language.

edit: sorry, posted incomplete code.

You could also generate a random alphanumeric string on the spot and use that as a placeholder delimiter.

edit 2: I'll look into a better revised version tonight, gotta go to work

Thanks for your suggestions, czardas and AZJIO. You're right about the delimiter being overly long but it was primarily meant as an example, although the longer the delimiter the less efficient the string lookup and replacing becomes...

Here's my revised version, it generates a temp delimiter on the fly that always starts with Chr(1). There's also a little part at the end to correct the array entries when the string passed was binary.

_ArrayDisplay(_StringRegExpSplit($sString, '[0-9]+.'))
Global $bBinary = Binary($sString)
_ArrayDisplay(_StringRegExpSplit($bBinary, '3[0-9]2E'))

$sDelim &= Chr(Random(0, 255, 1))

Do you know why I reduced the range up to 31?

The regular exp<b></b>ression must not be a combination of '1', '2' ... '9' or '$1', '$2' ... '$9'. Because it inserts the Group.

$ = Chr(36)

= Chr(92)

Chr(0) - sometimes that causes problems.

#include <Array.au3>
_Test(Chr(1))
_Test(Chr(0)) ; problems
Func _Test($spr)
    Dim $arr[6] = [1, 2, 3, 4, 5, 6]
    $Line = $spr & _ArrayToString($arr, $spr, 1) & $spr
    $aTmp = StringRegExp($Line, '(?i)' & $spr & '3' & $spr, 3)
    If Not @error And UBound($aTmp) = 1 Then
        MsgBox(0, 'Yes?', $aTmp[0])
    Else
        MsgBox(0, 'No', 'Error')
    EndIf
EndFunc

Any metacharacter causes problems: '?^()*+['.

What about something like.

$Passedstring = "BLAHDFRTUUJHGTFDEER"

_Delim($Passedstring)

Func _Delim($String)
    Local $delim = '', $rtn = ''
    Do
        For $i = 0 To 3
            $delim &= Chr(Random(65, 122, 1))
        Next
        $rtn = $delim
        $delim = ''
    Until Not StringInStr($String, $rtn, 1)
    Return $rtn
EndFunc   ;==>_Delim
