Hi all, I recently started to hack with Elm and I am having quite a lot of fun! Thanks to the community! After a successful prototype integrating CodeMirror, semantics-ui, elm-markdown and elm-split-pane, I wanted to go a step further and replace elm-split-pane with Golden Layout that makes a rema…

Usually, I’d say go for custom elements for something like “child node trees that are outside of elm’s scope” then use attributes+events to interact with the element through some interface you define. But, if I’m understanding it correctly, golden layout would need to be wrapping elm views, right? …

I think it should be OK to do it by having each pane of the Golden Layout be an Elm app. Communication between panes could be done with ports. Is it correct to say that TEA enforces that one can only update a single view backed by a single root node of the (virtual) DOM? Yes. One node per app. Y…

What about an new kind of VirtualDom node similar to keyedNode that would traverse the DOM from its current point, search (getElementById ?) for an element with a given id and resume compare/patch the virtual DOM from there ? findNodeById : String -> Node msg -> Node msg Applied to golden layout, …

Changes to VirtualDom are very difficult. You would have to come up with the implementation, make a strong case for its utility, do a performance impact analysis, etc. Elm is very conservative in its use of Javascript. In any case, as I said, the best way to do it with current tech would be to hav…

The elm compiler does not allow for custom html implementations so if you go that route you’re probably talking about forking the compiler… which has its own (huge) set of problems. If you can live with a non-elm root that starts all your leaf-elm apps it could be quite simple to go the multi elm a…

Thanks @georgesboris @pdamoc ! Of course having a single app is preferred here, because in a realistic app we don’t have just independent counters. Maintaining a coherent distributed state is hard and the essence of Elm is to avoid that. Theoretically speaking, would the solution involving the vir…

As far as I see the solution you proposed kinda requires you to break free of elm’s official compiler - you wouldn’t be able to ship it as a package and even if you maintained it just for yourself you would run into upgrade problems… at least this would be the situation in Elm’s current version (as …

I guess a nice solution would be to just build the same functionality that golden-layout has in pure elm. I would not start on something like that in react, but with elm and elm-ui, that does not seem impossible now :grinning: Also, golden layout seems a bit limited in functionality, thinking a bett…

Elm + Golden Layout, any hope?

Not necessarily recomending this approach to solve your problem, but there was this interesting experiment in writing a completely custom vdom on top of Elm, without hacking the compiler or kernel modules:
