Extra debug details possible?

[RaXaR]

I would like to know if it's possible to print the script + line number along with a print(something) call?

An example output of this function could be:

> Line:   16| .\scripts\mobs\mob_base.gd | "was hit!"
> Line:  172| .\scripts\mobs\mob_base.gd | 255
> Line:  4572| .\scripts\player\player.gd
> "This was a particularly long string so it printed out on a new line instead of wrapping."

The intent is of course to make it easier to trace debug output during development. If you forgot a random print(number) somewhere it can be pretty tedious to find it. It also helps to keep track of what's going on and where when you know where the printouts come from.

Another expansion could be to allow debug printing arrays and objects with clean and readable formatting. Here's an example of an array debug in one of my PHP scripts:

Line:   34| ...\controllers\somefile.php
Array
(
    [items] => Array
        (
            [0] => stdClass Object
                (
                    [item_id] => 126
                    [client_id] => 8
                    [note] => Some randome note.
                )

            [1] => stdClass Object
                (
                    [item_id] => 125
                    [client_id] => 22
                    [note] => Some randome note again.
                )
...

As you can see it's a lot easier to follow what's going one here. What are your thoughts?

Script and line number for print calls would be a nice idea indeed.

Was discussed in #3884 (although that is badly named and thus hard to find). It was said there that it wouldn't be that hard to do and even tagged as a junior job, however, I have no idea where to start on this.

Maybe somebody can make some suggestion on how this could be done?

There is a print_stack function, which might prove useful for that...

One day we should probably implement the line numbering proposed in #3884 as well 😃

[RaXaR]

print_stack() has all the info in it that I would want. But it doesn't take a parameter nor returns a string for custom parsing .. kind of limits it's usefulness.

Could it perhaps be get a variant that returns the string that is printed to console instead?
EDIT: or even take a boolean flag "return_string"
