Re: [elm-discuss] Re: Elm Runtime Exceptions

My thoughts: If you're dealing with Maybes from List.head and List.tail, you should be doing pattern matching on [] and x::xs instead. Working with Maybes doesn't have to be done painfully. You can get a lot of leverage with Maybe.map and similar functions. This allows you to write code *as

Re: [elm-discuss] Re: Elm Runtime Exceptions

I don't think the comparison to C is accurate at all. Error codes in C are a programming convention. As far as the compiler is concerned, all ints are created equal. Nothing is reminding the programmer to check for error codes. On Wed, Sep 7, 2016 at 1:00 PM, Joey Eremondi

Re: [elm-discuss] Re: Elm Runtime Exceptions

The worst offender for runtime errors right now, in my mind, is this: myTest = (\x -> x) == (\y -> y) This crashes and prints a message to the console. But this has been discussed at length. On Wed, Sep 7, 2016 at 12:54 PM, Charlie Koster wrote: > Having said all of that,

[elm-discuss] Re: Elm Runtime Exceptions

Your description of Maybe isn't correct. When a function returns a Maybe it's not throwing an exception. Maybe is a separate type (like String) so when a function returns a Maybe String that is the type of the returned value. It's saying the returned value is one of two things. It's a Nothing,

Re: [elm-discuss] Image navigation and interaction

For those use cases, it's common to build a pyramid of some sort from the original image(s). What that means is that you have the image the image as seem from different zoom levels in a format/organization that allows you load just enough data to show what you need. Loading a 20.000x20.000 image

Re: [elm-discuss] Elm Runtime Exceptions

So, a more nuanced statement would be "Elm has no unchecked runtime exceptions". We use Maybe and Result in place of Null and Exceptions. But the key is that the type system *forces* you to catch these. There's no (fromMaybe : Maybe a -> a) function, like there is in Haskell. What's also

[elm-discuss] Elm Runtime Exceptions

One of Elm’s most interesting features is "No Runtime Exceptions". But I would argue that Elm does in fact have Runtime Exceptions, even if you don't call it that. I explain my reasoning in this blog post: https://medium.com/@daveford/my-take-on-elm-runtime-exceptions-b3c5156887c9#.p1mrtcr2m
