OCaml has a set of extension points. You can write OCaml code, add it to an extension point (`derived` is precisely the use case of this) and it receives the AST of the expression and can transform it or add new code or whatever as you wish. Like a very common one for auto-json conversion

[elm-discuss] Elm benchmark

On the elm blog post that was posted recently: http://elm-lang.org/blog/blazing-fast-html-round-two The benchmark linked at: https://evancz.github.io/react-angular-ember-elm-performance-comparison/ I've repeatedly had results like this in Chrome:

[elm-discuss] Re: Simple Fade In/Out effect?

You can also do it via pure CSS via the 'transition' property, just have the old fade out at like 1s time and the new fade in starting at the 1s time (or 1.001s to prevent a flicker in some browsers) while flipping display:none at the 1s mark (or just deleting it then entirely). A method I

Re: [elm-discuss] I made Elm crash runtime...

As a comparison, this is how OCaml handles the same issue. OCaml uses built namespaces, meaning you can only use what was defined before you first of all, and if you want something to be able to refer to itself or something later on then you need to mark it explicitly ``` let v = v + 1 ```

[elm-discuss] Re: elm-make behavior different between localhost dev and production

Hmm, I use the same type of setup with the same type of arguments as you though I've not tried heroku. Is the elm version between your dev machine and heroku the same? It looks like you might be using phoenix, you really should be generating a production output of all files on your dev server

Re: [elm-discuss] About `programWithFlags` naming

I'd personally use `programWithArgs`, or just `program` and bake flags in, defaulting to an empty tuple or some other nil type or so that comes from javascript's `undefined`. Like define init via `init () = { blah model }` for the 'no argument' case, that way it accepts 'undefined' from

[elm-discuss] Re: Can anyone get linter-elm-make working on Atom?

It works fine for me (also get Atom's elmjutsu plugin, made by same person as linter-elm-make and they work wonderfully together). So first of all the src directory in elm-package.json should be as it normally is in elm-package.json, the root directory of all your elm source, mine for example

Re: [elm-discuss] Structuring a simple App

I would still like to find a good way to structure messages. I'm up to 146 in the base Msg type, and it is not flat, by counting it seems that I have 6 message types that just hold another message type for something further down, which average in size from 2 for 1 of them, 4 for 3 of them, 8

You can compile multiple main files together and they will share a code-base, standard library, and all such. On Thursday, September 22, 2016 at 8:01:58 AM UTC-6, Rupert Smith wrote: > > On Wednesday, September 21, 2016 at 10:59:00 PM UTC+1, John Mayer wrote: >> >> I also posit that
