add "goto" like in c++ to gdscript

This isn't a proposal, you need to fill out the different details, also a really bad idea in general

[vpellen]

Okay, one, bruh
Two, goto is disruptive enough that there's an argument for its inclusion being actively detrimental, which is not something I say often
Is there a particular issue you're having that goto would solve?

GDScript does not have any advanced optimization or analysis yet but it still would make scope management a nightmare, but goto generally makes code much harder to read

there was a problem, i could solve easier then i did, now i will check my code...

for example
i have this code

up. sorry code didnt tab

C++ has the most liberal goto statement of any high level language, and the only other mainstream one I can find is C# and it doesn't allow it outside of the current scope, why should GDScript go against the flow?

So since this is a feature proposal, how should goto handle various contexts? What goto should be permitted? How should error handling look?

var a
first:
var b
if ...:
    var c
    second:
    var d
goto second # Should this be allowed? How should it be treated?

Etc. etc.

Should this be allowed? How should it be treated?

hm, i see its impossible for gdscript, because of the architecture.(but iam not sure)
GDscript devs can make something like "passall" but this "passall" will pass all IFs local code in, like in my example above.

sorry for, but usually i speak russian

In JavaScript, this is possible (break from block, not goto). Docs: block, label, break.

my_label:
{
    console.log("A");
    if (true) {
        break my_label;
    }
    console.log("B");
}
console.log("C");

// Prints:
// A
// C

In GDScript it might look like this:

:my_label
block: # I couldn't think of a better name.
    print("A")
    if true:
        break my_label
    print("B")
print("C")

Break from nested loop:

:outer
for i in 10:
    :inner
    for j in 10:
        if true:
            break outer

[AThousandShips]

The break from loops, or nested breaks like break break has been suggested before I think, and is a feature I would like myself

See #3780 :)

Please, don't make low quality posts like that. If you want to open a discussion, then open a discussion. A proposal must have more thought put into it than just replicating the same sentence 10 times.

i am not professional github user. no russian lang

[AThousandShips]

What has that got to do with it? Were you unable to read the instructions?

[SlugFiller]

It's been said by others, but goto in C/C++ is just a poor workaround for the lack of a labelled break. In fact, it is used for specifically that purpose across the Godot's core code. If you're looking for a labelled break, you should ask for a labelled break. Not a goto. I might also add labelled continue, although that can be worked around using clever scoping and labelled break.

[Calinou]

#3780 covers labeled break.
