I'm not sure if I get it. But I don't know Clojure syntax too well. Say I want to represent a slideshow state. I could do it with
{
slides: List<Slide>,
current_index: Int
}
Or alternatively:
{
left_slides: List<Slide>,
current: Slide,
right_slides: List<Slide>
}
Is it fair to call the latter a Zipper?
- laszlokorte 1y agoYes if List is immutable and the interface for stepping through the slides ist designed accordingly
- shakadak 1y agoYes, although it's usually defined as: { slides_shown: List<Slide>, slides_left: List<Slide> } Where the head of slides_left is the current slide. Pretty much any recursive data structure can be derived into a zipper.
