Help with splitting up a string

Recommended Posts

darkjohn20

Hi, I'm working on a TCP Client and Server, and in order to eliminate Sleeping in between send commands, I've decided to add a terminator to each thing I send. (Thanks Kip)

My problem is, each command is one of these formats:

Hex($Code)|$Additional_Information~
Hex($Code)~

Example:

00000001|Hello?~
000000FF~

Where "~" is the terminator and "|" is just a split to know when the code ends and the information starts.

My question is, how can I easily separate multiple commands using the terminator, and then the split?

An example being:

00FA001E~0000CC01|Test String!@~00A0BBC0~

Where it should be split first like this:

00FA001E
0000CC01|Test String!@
00A0BBC0

and then those with additional information like this:

0000CC01
Test String!@

I was thinking maybe a StringSplit using the "~" and then the "|" but that seemed kind of messy.

Also, as a side note, the additional info parameter can include ANYTHING but the terminator. It is not limited to alpha-numeric.

I think it took more time writing that out then figuring out how to do it... :idea:

Anyways, I figured it out. Here it is:

Func _InfoReceived($hSocket, $sReceived, $iError)
    $Received = StringSplit($sReceived, $sTerminator)

    For $X = 1 To $Received[0]
        If $Received[$X] <> "" Then
            If Not StringInStr($Received[$X], "|") Then ;Code Only
                _EvaluateCode($Received[$X], $hSocket, $iError)
            Else ;Code and Information
                $Information = StringSplit($Received[$X], "|")
                _EvaluateCodeEx($Information[1], $Information[2], $hSocket, $iError)
            EndIf
        EndIf
    Next
EndFunc

I figured since I made the post I might as well post my solution for others.

I'm curious: why do you need the | separator at all, since I assume the hex code is fixed length?

True. I don't know. I like separators even if they aren't the cleanest method. Maybe I'll switch over to StringTrimLeft()...

That, or simply a single regexp to split things apart. It would simplify your life greatly if _EvaluateCodeEx() would accept an empty second argument and behave as _EvaluateCode().
