Function called by whom?

[ds34]

I have a procedure (to generate debug output) that is called about 10000 times in the script...

Since meanwhile the output is way too much I would like to limit the amount of messages printed WITHOUT needing to touch each call triggering the function but restricting it inside of the function.

So it would be really usefull, if a function could by itself determine, which function was calling it...

Is there something built in - would save my day ;-)

thanks,

Daniel

My script looks like

global $env_Debug="on"

 func Debugtrace($string="")
 if $env_Debug="on" then write to logfile (timestamp&some_environment_condition&string)
 endfunc

and everywhere else in the script it called

Debugtrace("blabla")

So I would like to change to something like below, then it is only acting when called by functiona but not when called from functionc

global $env_Debug="functiona_functionb_function10002

 func Debugtrace($string="")
 $called_from=??????
 if stringinstr($env_Debug,$called_from) then write to logfile (timestamp&some_environment_condition&string)
 endfunc

That would require some sort of function stack access. Either the devs would have to provide this or you would have to write something yourself, such as declare a stack(obviously more coding involved) and push the current function every time a function is called. Then you would have to pop the function when it ends.

Easiest way is to just have an extra parameter in your function., or have a global value that is set at the first line in each function.

Global $funcname = ''

.
.
Func FnOne()
$funcname = "FnOne"
..
.
.
DebugTrace("something")
Endfunc

Or

Func FnOne()
;blah
;blah
DebugTrace("something","FnOne")
etc

Thanks for thinking about this,

I also thought about declaring a global variable, to be sets upon every function entry.

This would require as well that the function itself, resets the variable before exiting to the previosly set vale (in case func a calls func b wich calls func c)...

In principle doable with a setting it directly after the "func" and reset before the "endfunc" statements, but I will need to set it es well before each and every Return or Exit statement - much work as well.

Since the project is too big already I consider this still too much effort...

Yes you're right , a global variable would not be a good idea. So you would need to add a local variable to each function and pass that to the debug function.

The effort required is minimal. One line in your debug function. Then a script of about 10 lines I would guess to read your script and add the line "Local $inFunction = "thisFunction" after each function header. That way each function has it's own variable which is its own name.

Thanks, that's the key, a local variable with the same name in each function (set directly after the function header) and a "find all and replace" of each DebugTrace function call: "DebugTrace(" to "DebugTrace($inFunction,".

I wonder if a stack trace would be a helpful thing to add to the AutoIt system.

[xwing1978]

I agree, a built in stack trace would be helpful.

So would using the "Trace: Add Func Trace Lines" option in SciTE and then running your script in SciTE not illuminate what the last function to call your debug function was?
