logging errors before a script crashes

[gcue]

is it possible to log errors before a script crashes?

i was looking at debugsetup and filewritelog but it seems you have to tell it where it should be writing to a log so as to predict where the error will occur. kinda tough especially for really long scripts.

is there something like COM ERROR capturing for autoit? can probably be logged there. if not, can anyone think of a way to capture these errors to a log?

thanks

You can use Tools->Trace: Add Trace Lines to add tracers to every line of your script. When you run the script from SciTE, it will write each line as it executes to the console, along with any error codes.

what about a compiled script?

Use the trace to find your problem areas and then add your own code for the errors.

what if i did something like this? would it capture any errors (before a crash) then write to the log?

while 1
  if @error then
    _filewritelog($log_file, "an error has occured with line number: " & @scriptlinenumber)
  endif
wend

Look into using OnAutoItExitRegister( "function" )

This won't help you in compiled scripts. According to the help file:

"@ScriptLineNumber - Line number currently being executed. Useful for debug statements specially when a function is called you can pass the caller line number. (Not significant in compiled script)"

i just tried this (doesn't seem to run that last function):

Opt("OnExitFunc", "CaptureSome")

"OnExitFunc" isn't an option according to the helpfile at least.

[gcue]

this was taken from OnAutoitExit function from the helpfile:

Opt("OnExitFunc", "endscript")

MsgBox(0,"","first statement")

Func endscript()

MsgBox(0,"","after last statement " & @EXITMETHOD)

EndFunc

edit: i think i have an older version.. updating---

OnAutoItStart and OnAutoItExit have been removed in version 3.3.4.0 and replaced by OnAutoItStartRegister, OnAutoItExitRegister and OnAutoItExitUnRegister (introduced with version 3.3.2.0).

What AutoIt version do you use?

<sorry about that.. i needed to update>

still doesn't seem to give a good clue to investigate the error that caused the crash

here's what the test i am running:

OnAutoItExitRegister("OnAutoItExit")

$ini = @ScriptDir & "\test.ini"

if FileExists($ini) Then
    FileDelete($ini)
EndIf

IniWrite($ini, "section", "key1", "value1")

$section = IniReadSection($ini, "section")

for $x = 1 to 2
    ConsoleWrite($section[$x][0] & @CRLF)
next

FileDelete($ini)

Func OnAutoItExit()
    MsgBox(0,"","script line number: " & @ScriptLineNumber & @crlf & _
    "exitmethod: " & @exitMethod & @crlf & _
    "exit code: " & @exitCode & @crlf & _
    "extended: " & @extended)
EndFunc

results:

script line number: -1

exit method: 0

exit code: 1

extended: 0

You can't use the script line number on a compiled script! There are no longer "script lines" when the script has been compiled.

You need to investigate your errors (called debugging) and then write your own code to handle them accordingly. You can pass variable information to be sent to the log, etc., but not the line at which the error occurs.

If you have an area with problems, log the error, and when you have it write the log, add the function name (or anything to help you identify it) into your error statement.
