Am looking at this from a performance point of view. You're marking components as dirty when there's any change in an atom being deref'ed by the component, right? But I'm guessing it's quite common for a component to be dealing with only a small subset of the data within a larger state atom. (This is what Om's cursors are addressing, it seems). In that case (please correct me if I'm wrong) - the number of needless rerenders will grow with the number of component-irrelevant bits of information in each atom. One simple way of addressing that is to use more, smaller atoms - or to use "views" on atoms (as Reflex does). For example instead of marking a component as dirty when @my-atom changes, we could mark it as dirty only when `(:relevant-submap @my-atom)` changes. Does that make sense, or am I misunderstanding something? -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
