Is this a bug in Au3Check or just how it's supposed to work?

5 posts in this topic

I copied a script from one of the help requests in the general forum and inadvertantly must have hit the space bar while looking at it. Au3Check gives me the following errors:

>Running AU3Check (1.54.22.0) from:F:PortableAutoIt3.3.8App

F:AutoItScriptstest.au3(13,10) : ERROR: syntax error

GUICtrl CreateLabel

~~~~~~~~^

F:AutoItScriptstest.au3(7,22) : ERROR: Timer(): undefined function.

AdlibRegister("Timer")

~~~~~~~~~~~~~~~~~~~~~^

F:AutoItScriptstest.au3 - 2 error(s), 0 warning(s)

!>13:12:32 AU3Check ended.rc:2

>Exit code: 0 Time: 2.956

The first error is actually the error, the Timer() function error shouldn't be listed as an error because there is a function named "Timer" further down in the script. I'm not sure if it's because the parser stopped at the syntax error that it doesn't see the function or what, but it could make debugging a script harder if you're trying to fix phantom errors.

BTW, here's the script that caused the errors:

; *** Demo to show a timer window
#include <GUIConstantsEx.au3>
#include <Date.au3>
Opt("TrayIconDebug", 1)
Opt("MustDeclareVars", 1)
Global $timer, $Secs, $Mins, $Hour, $Time
AdlibRegister("Timer")
_Main()

Func _Main()
    ;Create GUI
    GUICreate("Timer", 120, 50)
    GUICtrl CreateLabel("00:00:00", 10, 10)
    GUISetState()
    ;Start timer
    $timer = TimerInit()

    ;
    While 1
        ;FileWriteLine("debug.log",@min & ":" & @sec & " ==> before")
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                Exit
        EndSwitch
        ;FileWriteLine("debug.log",@min & ":" & @sec & " ==> after")
    WEnd
EndFunc   ;==>_Main
;
Func Timer()
    _TicksToTime(Int(TimerDiff($timer)), $Hour, $Mins, $Secs)
    Local $sTime = $Time ; save current time to be able to test and avoid flicker..
    $Time = StringFormat("%02i:%02i:%02i", $Hour, $Mins, $Secs)
    If $sTime <> $Time Then ControlSetText("Timer", "", "Static1", $Time)
EndFunc   ;==>Timer

The lexer stops on the syntax error and then processes the found Func name references. Since the Lexer stopped, au3check hasn't found all FUNCs yet, reporting this one as an error.

This has to do with the single pass design of au3check.

BrewManNH,

I have noticed this before - there is a similar "feature" in Tidy. In both cases the parser runs out of ideas following the first "real" error and brings up a lot of subsequent "errors" because it is confused. :)

I now make sure I skim through the notified errors to see which is the first obvious idiocy I have committed and then immediately rerun Au3Check/Tidy to see if the others still exist. In the case where you know the script was good before you made an amendment it is relatively easy to understand why the AdlibRegister might throw an error - it is more difficult if you are running the script through these checks for the first time. ;)

But I stil think both these utilties are worth their weight in gold and would not wish to criticize the authors - after all if I did not make mistakes in the first place they would not have to cope with my syntactic stupidities! ;)

Always fix the first error encountered and then re-run the error checking tool. Always. I don't care if it's AutoIt, C++, Python or any other language. Fix the first error, re-run the tool. Repeat until all errors are fixed.

As long as I know WHY it reported the error, I can work with it. It just confused me, and I figured it's better to ask than assume it's a bug rather than "that's how it is supposed to work". I can deal with the latter easier than the former. :)
