[elm-discuss] Re: why no more primes on 0.18 ?

Primes I'll miss for convenience, like when naming an inner tail-recursion function to distinguish it from its wrapper. But it's not a big deal. As for back-ticks, I've never used them in Elm, but I use them in F# for defining human readable Unit Tests names. For example: []let ``Test that

Re: [elm-discuss] why no more primes on 0.18 ?

Primes can be confusing even when doing pure maths (I studied physics), it's just so easy to miss them, so good riddance. When it comes to model names, I always try to 1) pipe my functions so that I need the least intermediate variable names and 2) use descriptive names no matter what; for

Re: [elm-discuss] why no more primes on 0.18 ?

Naming sometimes can be hard. While I agree that model03 or model''' is a code smell. But often you are just transforming some data and the intermediate variables names are meaningless (besides reminding us that they are related) I've seen things like newModel being used everywhere and then

Re: [elm-discuss] why no more primes on 0.18 ?

I use primes surprisingly often as well since if I have "newModel" then I probably also want "oldModel" rather than just "model" but I don't feel really strongly about it. I do, however, think that underscores would be worse than primes for API cases where the normal identifier isn't available

Why don’t you enrich your Msg type like so: type Msg = ... | Several (List Msg) and add a generic branch to your update function for processing a message of the Several kind (something in the spirit of: update (Several msgs) = List.foldr (... calling update recursively in an appropriate way ...)

[elm-discuss] Re: Generating a batched Cmd of more than one msg from Task.perform

Yes, my current approach does seem pretty solid from a theoretical point of view, but it feels like a poor expression of my intent. I have to create this "synthetic" intermediate msg which only exists for the purposes of the recursion, and then I have to handle the production of two messages in

[elm-discuss] Re: Generating a batched Cmd of more than one msg from Task.perform

I don't think I follow your logic. If my task produced a batch Cmd somehow (I'm not even sure how I would do that), that would still get passed to my success handler in Task.perform. That handler has to produce a single msg (i.e. not a Cmd, so batching isn't involved) which is then used by

GraphQL could be part of the answer. I would love to see an answer that includes GraphQL being explored. Ideally, I would love to see it explored in a more complex context where the data set is very large. e.g. some kind of application over the data from MusicBrainz. Let's say that I want to

Is there a way to make Task.perform produce a batched "Cmd msg" on success (or failure, for that matter)? I've got a case where, on success, I want to send out more than one Msg, but because the success handler for Task.perform can only generate one msg this isn't straightforward. What I'm
