Make undo feature?

[cool-RR]

If so, only one step or more?

[darvin]

i think it is bad idea becouse current model. i vote for close this issue

[cool-RR]

I can't understand your argument.

[darvin]

i mean in OOP mode it is complicated,
in functional mode it may be ok

[cool-RR]

Well, let's worry about that later.

I'm not sure I understand. But in general, having "usual" editing capabilities (copy, cut, paste, undo, redo) in the interpreter would be very nice, of course.

P.S.: Has anyone ever suggested adding auto completion? (Using this feature efficiently is also something that young programmers need to learn! -- This is actually taught on sites like Hour of Code, IIRC.)

Undo means for the turtle, not for the code. E.g. if you did go 100 and then undo, the turtle would walk back and delete that line.

That sounds funny. I'd let this allow using code, though. Would make sense. Kind of, "activate eraser" and walk backwards (the users should figure that out themselves). But that gets complicated, quickly. 😕

A "wheel" in the UI to walk the steps backwards? Sounds crazy. Cool, but crazy to implement. If it provides more insight into understanding how the code works -- why not?

I don't think it should be in the UI, it should be a command that can be used in code. I think that the `turtle` module in Python has that.

You're right: https://docs.python.org/3/library/turtle.html#turtle.undo
