Re: [elm-discuss] Re: How are deeply nested records updated or what alternatives are typically used?

In the previous posting there is a bug -- I should simply use e = ... instead of e = f ... If you want to make the previous write up work, then you need f : X -> E and ... is of type X rather than the following which is a mistake. f: E -> X and ... is of type E On Tuesday, August 2,

Re: [elm-discuss] Re: How are deeply nested records updated or what alternatives are typically used?

I think that would be the case. Although, I'd imagine I'd be using dictionaries in this situation once I get to the point of having "Maybe" data in this particular example. I am beginning to understand the value of flattening data structures in this context. On Tuesday, August 2, 2016 at

Hi all, I really appreciate the ample feedback. As I am new to the functional style, Sergey, your input is extremely helpful. For some reason, I felt like I was supposed to have all my modifiers and data structure definitions in one place, which became unmanageable. I am currently refactoring

Correction: what I should have written is: { model | primaryForecast.parameters.q = ... } instead of { model | model.primaryForecast.parameters.q = ... } because the former is more consistent with the notion that the field between the | and the = must exist inside the record to the left of

I think we should wait for Elm to get typeclasses and use lenses for that. https://en.wikibooks.org/wiki/Haskell/Lenses_and_functional_references -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group. To unsubscribe from this group and stop receiving

You might want to look into the Focus library: http://package.elm-lang.org/packages/evancz/focus/2.0.1/ But as you probably want to render your data as html, I would recommend you to break your data into modules and use the Elm Architecture:

As far as I know, this is how you must do at present. It's a recorded issue though (https://github.com/elm-lang/elm-compiler/issues/1375) so it will hopefully be fixed in a future release. -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group. To
