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

Hi, I come from an OOP background and trying to make the leap to keeping all state in a single immutable data store, which has shown to be amazing as long as the system is small, but I am having trouble scaling up to anything beyond a toy app. One big challenge is trying to update nested

Re: [elm-discuss] Elm Records as a platform-agnostic data type?

I'm not sure this is a great idea. Syntax-wise, Elm records aren't different that much from JSON. But in terms of semantics, they can store any Elm value, which includes functions and other things that can't be serialized well. At the end of the day, an Elm record is just a mapping from names to

Re: [elm-discuss] Equality Error Undecidable

I think I'm going to revise my stance on how this issue should be handled. I am now gong to argue that function equality should be handled via object identity — i.e., two closures constructed at different times are necessarily unequal. What this breaks is referential transparency and more

[elm-discuss] Re: Is there a better way to structure my List types?

As another way to think about this, and I am unsure how Elm'ish this is (but it is very functional), you could invert your lists into being functions, then pass in commands to operate on the internal lists. This is how some functional list implementations are developed especially when missing

Re: [elm-discuss] Re: Is there a better way to structure my List types?

I was thinking I might want List.take and List.drop for pagination purposes but in seems like the easiest way in this particular case is to do all that generic list manipulation ahead of time when I have the plain lists, before I add the types. But if dynamic pagination was a hard requirement then

[elm-discuss] Re: Using Elm with jQuery (ports)

For future note, the Elm DOM is not created until the view function is run for the first time, which happens after init, which happens sometime 'after' the elm app creation. Always use callbacks to synch things, never assume any timing (my `cmd_delay` call I use heavily for such

Re: [elm-discuss] "I know what I'm doing"-syntax and helpful error messages for string interpolation

I think the compiler would be far exceeding its job description if it was trying to identify the language of every string! This sounds like it would be better as part of a separate validation tool. And of course, there's no telling when (if?!) string interpolation gets added to the language.

Re: [elm-discuss] Re: Is there a better way to structure my List types?

I don't mean to gloss over the fact that the length function you had to write is a little verbose. But I don't think there are a lot of other operations that would be applicable to every type of list in ThingList. For instance, folding and mapping wouldn't work, because the fold/map function would

HI! I want to use tags-input widget which attaches some attributes to certain element in my body. The idea is to create normal input field on the elm side and later implement additional functionality via ports. So my approach is to load compiled Elm-js code and later once site loads

Zach, Of course being backend agnostic is an amazing thing. That being said, I would love to have a backend that could be implemented in Elm and one full-stack solution that has perfect impedance match. This way, the data models can be shared between the backend and the front-end and with a

Hi Neil, Few comments on the issues you've raised: 1. Elm plans to go to the server side too. There are already proof-of-concept that allows one to use Elm server-side and with the advent of 0.18 (next version) we might see official support for that. Also, one could use something like Horizon
