Debug-console version of AutoIt3.exe and AutoIt3_x64.exe?

Debug-console version of AutoIt3.exe and AutoIt3_x64.exe?

I want to test my script (it already passes Au3Check.exe) by running it through CMD,

and I want any errors (crashes, syntax errors, array index issues, invalid assignments, etc.) to be printed directly to the console instead of stopping the program and showing an error message box.
Those pop-up error dialogs make debugging difficult because I have to switch back to SciTE every time.

What I’m asking for is a console-mode debug version of AutoIt3.exe/AutoIt3_x64.exe that, when an error occurs, prints the error to the console and exits immediately with a non-zero exit code.

 

And with compiled scripts too, is it possible to print a message on console instead of showing it?

SciTE don't get those popups. They run with "/ErrorStdOut."
Then you also have Opt("SetExitCode",1) 1 = Set @exitCode on Fatal error - see Exitcodes.

If that is not enough then, let me know.

P.S.: I really like the open source code you're integrating. Like really really like it. Thanks for that 💯

I wrote an example some time ago too ( https://www.autoitscript.com/forum/topic/209902-optsetexitcode01 )

; Script Start - Add your code below here

FileChangeDir(@ScriptDir) ; my AutoIt is installed there

Opt("TrayAutoPause", 0) ; Script pauses when click on tray icon = OFF/0
Opt("TrayOnEventMode", 0) ; Enable/disable OnEvent functions notifications for the tray = OFF/0
Opt("GUICloseOnESC", 1) ; When ESC is pressed on a GUI the $GUI_EVENT_CLOSE message is sent = ON/1

#pragma compile(Console, True)
#pragma compile(AutoItExecuteAllowed, True)

..also used the above and instead of running a script with AutoIt3.exe, I would run it with Autoit3cui.exe
If these cui versions are in the same folder as AutoIt3.exe, all will be running just fine.

It seems not to be the optimal solution.
Even running with /ErrorStdOut still does not show the error on the console, only when running with SCITE !!

Does anyone know how to use this command?  /ErrorStdOut

I had a similar problem a long time ago. A server application started my script. In rare cases, the script crashed due to faulty data.
Trancexx helped me with this code.

Or make a simply RunConsole.au3 script and compile it:

expandcollapse popup

#AutoIt3Wrapper_Change2CUI=y
$pgm = '"C:\Program Files (x86)\AutoIt3\AutoIt3.exe" /ErrorStdOut "' & $CMDLineRAW & '"'
_RunCMDPgm($pgm)

Func _RunCMDPgm($pgm)
    Local $pid
    $pid = Run($pgm, '', @SW_HIDE, 1 + 2 + 4)
    Local $handle = _ProcessExitCode($pid)
    ShowStdOutErr($pid)
    Local $exitcode = _ProcessExitCode($pid, $handle)
    _ProcessCloseHandle($handle)
    ConsoleWrite("+ Ended  rc:" & $exitcode & @LF)
    SetError($exitcode)
EndFunc   ;==>_RunCMDPgm
;
Func _ProcessExitCode($i_Pid, $h_Process = 0)
    ; 0 = Return Process Handle of PID else use Handle to Return Exitcode of a PID
    Local $v_Placeholder
    If Not IsArray($h_Process) Then
        ; Return the process handle of a PID
        $h_Process = DllCall('kernel32.dll', 'ptr', 'OpenProcess', 'int', 0x400, 'int', 0, 'int', $i_Pid)
        If Not @error Then Return $h_Process
    Else
        ; Return Process Exitcode of PID
        $h_Process = DllCall('kernel32.dll', 'ptr', 'GetExitCodeProcess', 'ptr', $h_Process[0], 'int*', $v_Placeholder)
        If Not @error Then Return $h_Process[2]
    EndIf
    Return 0
EndFunc   ;==>_ProcessExitCode
;
Func _ProcessCloseHandle($h_Process)
    ; Close the process handle of a PID
    DllCall('kernel32.dll', 'ptr', 'CloseHandle', 'ptr', $h_Process)
    If Not @error Then Return 1
    Return 0
EndFunc   ;==>_ProcessCloseHandle
;
Func ShowStdOutErr($l_Handle)
    Local $Line, $tot_out, $err1 = 0, $err2 = 0
    Do
        Sleep(10)
        $Line = StdoutRead($l_Handle)
        $err1 = @error
        ConsoleWrite($Line)
        $Lineerr = StderrRead($l_Handle)
        $err2 = @error
        ConsoleWrite($Lineerr)
    Until $err1 And $err2
    Return
EndFunc   ;==>ShowStdOutErr

Then run the script from the console with this compiled program:

C:\test>RunConsole.exe "C:\test\test.au3"
$CMDLineRAW=/ErrorStdOut ""C:\test\test.au3""
"C:\test\test.au3" (6) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$x [10] = 9
^ ERROR
+ Ended  rc:1

.. and bob's your uncle. 😉

Hi @Trong.

The issue is the way AutoIt3.exe does outputs from it's runtime
My suggestion is based on this: https://stackoverflow.com/a/54252275

"D:\Downloads\autoit-v3.3.16.1\install\AutoIt3.exe" /ErrorStdOut "D:\Downloads\autoit-v3.3.16.1\install\test.au3" 2>&1|more

this was my test script:

ConsoleWrite("ConsoleWriteTest"&@crlf)
Local $x[1]
$x[10] = 9
MsgBox(0, "aya", "yay")

and here is the result:

cool, it seems like a different way.

Because you need to "echo %ERRORLEVEL%". That is the "rc:1" on SciTE.

[argumentum]

ok, my bad I guess ( because I didn't test with errors as my code is always perfect  )
AutoItCui.bat:

@Echo OFF
:: AutoItCui.bat ; name of the batch file that runs Autoit3cui
Autoit3cui /ErrorStdOut /AutoIt3ExecuteScript %*
echo rc:%errorlevel%

With the above batch file you'd run your script. Say:

Opt("SetExitCode",1)
Global $a[1]
$a[1] = 1

and the output would be:

>Autoitcui MyFlaw.au3
"D:\Utilities\AutoIt3\MyFlaw.au3" (3) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$a[1] = 1
^ ERROR
rc:2147479674

were the 2147479674 errorlevel in hex is 0x7FFFF07A.

So the code I posted in the beginning is all that is really needed.
