Ability to stop repeating content

[Xac]

I'd like the ability to start something repeating for one section of a document, and to stop that item from repeating when the section is through. Is this something that may come in a future version?

Looking at the code for repeaters, this doesn't seem like it would be difficult to add. Perhaps the ability to name a repeater and remove it by name, or for the repeat method to return an index to pass to a stop_repeater method?

Can't this already be done using a Proc? See the examples.

I would need to do something like:

@sections.push "foo"
repeat(lambda { @sections.include? "foo" }) do
  text "=== In section Foo ==="
end
500.times{ text "foo content" }
@sections.delete_if{|s| s == "foo"}
500.times { text "non-foo content" }

But it doesn't look like this works, scoping issues?

Don't use an instance variable.

[Xac]

How would you suggest doing the above example without using an instance variable?

[practicingruby]

A local variable. You know, the thing a closure closes over? :)

[practicingruby]

But nevermind, I'm pretty sure that given the current way that repeaters are implemented, this code will be executed too late, only after you deleted your section.

I need to think of a better way to implement repeaters to give you this sort of control. Closing this issue for now, please re-open it after I do some refactorings if it still doesn't do what you need.

Right, it seemed like it was being executed after the section had been removed. Thanks, looking forward to the refactorings.
