Hi guys, i have a little problem to set the @error to _StringBetween

The script:

While 1
  $line = StdoutRead($CMDCommand)
  If @error Then ExitLoop
  $tmp = _StringBetween($line, "] ", '%')
  If Not @error Then
   $replace = StringReplace($tmp[0], "%", "")
   MsgBox(64, "Test", "string found")
  EndIf
WEnd

This script working, but i need to set something if the string don't match. I have try like this:

While 1
  $line = StdoutRead($CMDCommand)
  If @error Then ExitLoop
  $tmp = _StringBetween($line, "] ", '%')
  If Not @error Then
   $replace = StringReplace($tmp[0], "%", "")
   MsgBox(64, "Test", "string found")
  Else
   MsgBox(17, "Test", "no string found")
  EndIf
WEnd

But i have everytime the error MsgBox also if the string is found. Some advice?

Thanks for support

johnmcloud,

Your logic works for me. In this example I have just reversed the order of the test - why use Not if you do not have to? :)

#include <String.au3>

Global $aLines[3] = ["works] 34%", "Fails", "works] 57%"]

For $i = 0 To 2
    $sLine = $aLines[$i]
    $aFound = _StringBetween($sLine, "] ", '%')
    If @error Then
        MsgBox(0, "Test " & $i, "no string found")
    Else
        $sReplace = StringReplace($aFound[0], "%", "")
        MsgBox(0, "Test " & $i, "string found" & @CRLF & $aFound[0] & @CRLF & $sReplace)
    EndIf
Next

And why do you use the StringReplace line? As you can see the & does not form part of the string returned by _StringBetween. ;)

johnmcloud,

So when you run that exact code I posted you it always says it found "no string"? :)

Have you recoded your _StringBetween function at all? ;)

Yes, your code:

#include <String.au3>

Global $aLines[3] = ["works] 34%", "Fails", "works] 57%"]
For $i = 0 To 2
    $sLine = $aLines[$i]
    $aFound = _StringBetween($sLine, "] ", '%')
    If @error Then
        ConsoleWrite("Test " & $i & "no string found")
    Else
        $sReplace = StringReplace($aFound[0], "%", "")
        ConsoleWrite("Test " & $i & "string found" & @CRLF & $aFound[0] & @CRLF & $sReplace)
    EndIf
Next

The result:

Test 0string found
34
34Test 1no string foundTest 2string found

>Exit code: 0   Time: 1.947

johnmcloud,

Using your data also works fine for me:

#include <String.au3>

Global $aLines[11] = ["[download]   0.0% of 3.52M at    ---b/s ETA --:--", _
                    "[download]   0.1% of 3.52M at    ---b/s ETA --:--", _
                    "[download]   0.2% of 3.52M at  116.67k/s ETA 00:30", _
                    "[download]   0.4% of 3.52M at  187.50k/s ETA 00:19", _
                    "fred", _
                    "[download]   0.9% of 3.52M at  221.43k/s ETA 00:16", _
                    "[download]   1.7% of 3.52M at  273.91k/s ETA 00:12", _
                    "[download]   3.5% of 3.52M at  352.78k/s ETA 00:09", _
                    "fred", _
                    "[download]   7.1% of 3.52M at  425.00k/s ETA 00:07", _
                    "[download]  14.2% of 3.52M at  468.38k/s ETA 00:06"]

For $i = 0 To UBound($aLines) - 1
    $sLine = $aLines[$i]
    $aFound = _StringBetween($sLine, "] ", '%')
    If @error Then
        ConsoleWrite($i & " - " & "No string" & @CRLF)
        ;MsgBox(0, "Test " & $i, "no string found")
    Else
        ConsoleWrite($i & " - " & $aFound[0] & @CRLF)
        ;MsgBox(0, "Test " & $i, "string found" & @CRLF & $aFound[0] & @CRLF & $sReplace)
    EndIf
Next

Result:

0 -   0.0
1 -   0.1
2 -   0.2
3 -   0.4
4 - No string
5 -   0.9
6 -   1.7
7 -   3.5
8 - No string
9 -   7.1
10 -  14.2

How about when you run it? :)

johnmcloud,

That will not work as you do not get an array returned from StdoutRead. I only used the For...Next loop as an example. ;)

Perhaps this:

Global $aFound

While 1
    $line = StdoutRead($CMDCommand)
    If @error Then ExitLoop
    $aFound = _StringBetween($sLine, "] ", '%')
    If @error Then
        ConsoleWrite($i & " - " & "No string" & @CRLF)
        ;MsgBox(0, "Test " & $i, "no string found")
    Else
        ConsoleWrite($i & " - " & $aFound[0] & @CRLF)
        ;MsgBox(0, "Test " & $i, "string found" & @CRLF & $aFound[0] & @CRLF & $sReplace)
    EndIf

    If $fInterrupt <> 0 Then ; Stop Loop
        Stop_Download()
        MsgBox(16, "Information", "Interrupt")
        Return
    EndIf
    
WEnd

Any luck? :)

johnmcloud,

Run this so we can see exactly what you actually get from the stream:

Global $aFound

While 1
    $line = StdoutRead($CMDCommand)
    If @error Then ExitLoop
    $aFound = _StringBetween($sLine, "] ", '%')
    If @error Then
        ConsoleWrite($i & " - " & $sLine & " = " & "No string" & @CRLF)
        ;MsgBox(0, "Test " & $i, "no string found")
    Else
        ConsoleWrite($i & " - " & $sLine & " = " & $aFound[0] & @CRLF)
        ;MsgBox(0, "Test " & $i, "string found" & @CRLF & $aFound[0] & @CRLF & $sReplace)
    EndIf

    If $fInterrupt <> 0 Then ; Stop Loop
        Stop_Download()
        MsgBox(16, "Information", "Interrupt")
        Return
    EndIf

WEnd

Now we will check exactly what you are getting and whether the function should return something. :)

johnmcloud,

Sorry about the $i - but as I cannot test for the same input as you.... ;)

What did you actually get in the console? The output line should include the actual line we are using as well as "No string". If there was nothing in the line then you cannot expect to find anything within it. :)

I'll post the entire code, so you can test it, if you want:

"Script is broken, i'll post only if full working"

Mine is only a test, i have many other command-line software, the principle is always the same

Guys, i think i can figure out how resolve the problem, but i need another little information. I can't write on a txt the log of a stderrRead, what is the problem?

Local $txt = @WorkingDir & "log.txt"
Local $txtread = FileRead($ini)

$Error = StderrRead($CMDCommand)
$logCreate = FileOpen($txt, 2)
FileWrite($logCreate, $Error)
FileClose($txt)

The file is empty, but on consolewrite i see a result, so what is my error? Thanks for support

EDIT: Solved adding a Dim on all $var

      [SOLVED] _StringBetween can remove?
      By johnmcloud
      Hi guys, i have a simple question. Sometime i'm using _StringBetween for situation like this:

      $test = "asdtewe[asdsad231321132@#]" $string = _StringBetween($test,"[","]") ConsoleWrite($string)
      Result is:

      asdsad231321132@#
      But if i want to remove that piece of string? Example remove all character/number/symbol between "[" and "]", included the "[" "]"? For a result like this:

      asdtewe
      Someone can post an example?
