Re: [elm-discuss] Re: Code review request

It’s some form of compiler bug. If in your gist, you replace the output type HasX a by { a | x : Float }, which is its definition, then the gist will suddenly compile. So I think you should try to bring this example down to a minimal case and then open a bug report at

[elm-discuss] Re: Composability without extensible records

While I understand that not breaking things up too often is sound advice in elm, I still think this doesn't answer my question: you're basically saying "you're doing it way too often" but you're not saying "don't do it at all" so I do need to find a scalable way of doing it a bit. The problem I

As far as I know there is no official list, but Elm's compiler output is plain old ECMAScript 5, so I imagine its compatibility table looks the same as this . On Tue, Aug 23, 2016 at 9:45 AM, Max Froumentin wrote: > Hi there,

Re: [elm-discuss] Dynamic implementation resolving

I am not sure what you mean by routing to an implementation "in a generic way". You can clean up your code a lot by merging your "Model" type with "Impl". This is the more idiomatic way of writing in Elm: type alias Model = CreateInvoiceImpl CreateInvoice.Model | SendTextImpl

Re: [elm-discuss] Unrelated modules having ports with the same name

This is the intended behavior. The strange thing about what you are trying to do is that ModuleA and ModuleB both have a function called main. Are you intending them to be a part of the same program? Programs should only have one "main" function. If ModuleA and ModuleB are supposed to be

I think you are seeing the intended behavior. In the first example, you're generating one Elm runtime that includes ModuleA and ModuleB, in the second example, you're generating two different elm runtimes, and that's the reason there isn't any name collision. You can easily check this by

Although I'd love to be able to use and compose port commands like tasks, I'm not a big fan of this solution. regular ports only let you send data off or receive data back, not both. This is a good design decision. Ports isolate Elm from the underlaying language (javascript) and avoids
