[elm-discuss] Re: webpack hotloading: compile errror leads to loss of state

Is this with elm-webpack-loader, or some other package? I use elm-webpack-loader and the webpack-dev-server, and it definitely recovers after a broken compilation. You can see my configuration here if that helps: https://github.com/abingham/accu-2017-elm-app On Saturday, February 25, 2017 at

[elm-discuss] Mysterious failure to find packages during compilation

I'm trying to sort out a compilation problem that I (really, a friend trying to use my code) is seeing. In a nutshell, when he compiles my project he sees this: ERROR in ./src/Main.elm Module build failed: Error: Compiler process exited with error Compilation failed Could not find

[elm-discuss] Guidance for using "type alias" vs. single-constructor union types

I recently had to chase down a bug where I was calling a function with the arguments in the wrong order. The function's declared argument types were each an alias for string, so the compiler happily let me swap them. In order to avoid this in the future, I'm experimenting with using

Ah ha! That bit of syntax is exactly what I was looking for. That get's me a lot of what I was hoping for. Regarding the use of helper functions, I agree in principle. But in my particular case, at least, I think it's mostly an academic issue. I want to distinguish between various "classes" of

[elm-discuss] Errors when using Chart.js in a port subscription

I'm trying to use Chart.js from my elm app, and I'm running into some errors that I can't sort out. In short, I've got a elm-to-javascript port that takes in a data structure describing the chart I want to draw. Then on the javascript side I've got a subscription to that port that renders that

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

You might look at lenses (e.g. elm-monocle) to see one approach that might appeal to you. Lenses are apparently frowned upon by some, but I think they capture the essence of what you're asking. On Tue, Nov 22, 2016 at 4:04 PM Wouter In t Velt wrote: > Op dinsdag 22

I've got a situation where I've got task that will always succeed, and I want to know the best practice for using it with Task.perform. The task itself is a Task.sequence of tasks that may individually fail, and I want to report the result - success or failure - for each of them. So there's no

Re: [elm-discuss] Cmd.andThen

As a relative newcomer to Elm, the impression I have is that Cmd is "special" and really part of the underlying runtime world. Maybe this is a misconception, but the impenetrability of Cmd gives it that sense. At the same time, Task is accessible, well supported, and put forward as the proper way
