Re: [elm-discuss] why -> Sub msg in ports instead of Sub Msg

Lowercase "msg" is just a type parameter. It says that the first and second occurence of "msg" in the type signature means the same type, whatever that type it actually is. If it was Sub Msg, Msg would be some actual type you would be forced to work with. Petr On Thu, Oct 13, 2016 at 6:42 PM,

[elm-discuss] Can I use css animations normally in elm?

Whenever I google something like this, I always get discussions about Elm libraries for this. As someone new to css in general, I just want to be able to do normal css animations using elm to model the state, do the event handling, and render the html. For example, if the state is toggled in

[elm-discuss] Re: Getting functions out of the model

The elm-autocomplete package does something much like you describe. Configuration data, including some functions, is defined separately from the model and is passed as an additional parameter to the update function.

[elm-discuss] Re: Getting functions out of the model

That's interesting as well. Though I think you'd run into challenges when trying to handle interruptible animations. Specifically you'd have to do all the interruptions manually. This would be even more challenging in the context of interruptions that have a delay before they're supposed to

[elm-discuss] Re: Getting functions out of the model

So it's not necessarily not having interruptible animations, it's more all the code that you'll need to manage them. In elm-style-animation you can just start a new animation and interruptions are handled automatically. When you have description and state split, you have to juggle switching

[elm-discuss] Re: Getting functions out of the model

I also thought about this problem for a bit. I came up with a slightly different solution. I was not only not happy with storing functions in my model, but also with storing static values in the model (e.g. stuff that wont change often). I think it would be nice to separate the *descriptions* of

@Frederick Yes, that's where I got my inspiration from ;) @Matthew I don't think this is a problem, but I also don't understand what you mean by "you'd have to do all the interruptions manually". Could you elaborate? I haven't studies your library closely, so I don't know how your library

[elm-discuss] Re: Getting functions out of the model

These are some very good points. I don't see how a library that doesn't store functions in the model could deal with these situations as easy as your library does. The only possible solution I can think of is that you could extend the description of an animation to include possible future

That's an interesting approach, though I'm not sure it would work for elm-style-animation, at least in its current form. In elm-style-animation you compose an animation under one Msg, and send animation updates(basically tick the animation forward) via a separate Msg. The `apply` and

[elm-discuss] Getting functions out of the model

As mentioned in some recent threads [1] [2], easing functions for animations have been an example of where functions in the model are currently used. An alternative approach is to use a union type to indicate the easing, but a suggested shortcoming of that approach is that there would then be no
