Actually what I said about elm-reactor is not necessarily true anymore (it was before 0.17).

Re: [elm-discuss] Download elm
Here is what you can do (if you have at least GHC 7.10 and cabal 1.18 on that machine, and if cabal had a chance to update its package cache at least once recently on that machine, by running cabal update, which itself requires internet access): Create the following directory structure: Elm-Platform\ Elm-Platform\elm-compiler Elm-Platform\elm-package Elm-Platform\elm-make Elm-Platform\elm-repl The contents of these directories you get by downloading the 0.17 release zips from GitHub. For example, up front download https://github.com/elm-lang/elm-compiler/archive/0.17.0.zip, unzip it, and rename the contained directory elm-compiler-0.17.0 into simply elm-compiler. Then, inside the Elm-Platform directory run: cabal sandbox init cabal sandbox add-source elm-compiler cabal sandbox add-source elm-package cabal sandbox add-source elm-make cabal sandbox add-source elm-repl cabal install -j --only-dependencies --ghc-options="-w" elm-compiler elm-package elm-make elm-repl cabal install -j elm-compiler elm-package elm-make elm-repl This will not give you elm-reactor. It’s simply impossible to build that without internet access during the build. Also, even after you have successfully installed the above way without internet access, actually using the tools will require internet access for elm-package to download stuff. But you can prepare Elm project directories on another machine, install packages there, then move them over to the machine without internet access. 2016-05-31 6:34 GMT+02:00 Nikhil Dhar : > Yes ,, >> > Actually I have to build this without using internet ,,, > and Buildfromsource.hs uses internet while running > > -- > You received this message because you are subscribed to the Google Groups > "Elm Discuss" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to elm-discuss+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.

Re: [elm-discuss] effect module … where {…} exposing …
Witold,
I believe the docs will eventually be in
http://guide.elm-lang.org/effect_managers/. As far as I understand them,
they allow a library author to describe how side-effects happen, letting
the runtime bridge your purely functional code and the messy world around
it. Some descriptions of the API lie here:
http://package.elm-lang.org/packages/elm-lang/core/4.0.1/Platform
Best,
Vitor.

[elm-discuss] effect module … where {…} exposing …
Hi,
I am looking at:
https://github.com/evancz/elm-architecture-tutorial/blob/master/examples/6-clock.elm
… and trying to figure out what's going on there. The official guide does
not cover this, I guess it's because it's a work in progress for 0.17.
So, there is:
subscriptions : Model -> Sub Msg
subscriptions model =
Time.every second Tick
and the subscription is "picked" by
Html.program's
{ ..., subscriptions: subscriptions ... }
That part seems easy: "someone" (aka the Html Framework) just fires the
thing and the timer begins to tick. So far so good, but I was wondering
what Time.every is… The Time.elm starts like this:
effect module Time where { subscription = MySub } exposing […]
What does "effect module" mean? I tried to find this in
http://elm-lang.org/docs (Syntax, Package Design), but it's not there. Is
it something so new it's just not there yet or I can't find it? What does
it mean? Is it something very special, part of Elm's syntax, or is it just
an instance of some template/generic kind of module?

I'll re-run the scripts I used to generate the graph periodically, so it might be interesting to check back in a few weeks time.

Re: [elm-discuss] Download elm
I'm confused what the actual problem is. You need to use internet to get Elm. Are you in a situation where you're behind a proxy? The npm page I linked gives instructions for how to deal with that. If you want to build them yourself, you need to download elm-compiler, elm-make, and elm-package from GitHub, as well as elm-reactor and elm-repl if you want. Then you need to compile them in the same Cabal sandbox. You can look at this file to see what's actually going on: https://github.com/elm-lang/elm-platform/blob/master/installers/BuildFromSource.hs It fetches the packages from GitHub, the builds them in the correct order. You could fetch them yourself, then edit the script to only build them.

Re: [elm-discuss] Download elm

Hi,
I'm new at this too and just experimenting. The model structured is
presented below. I don't think it has much to do with the model, but more
to do with the fact that the update in Child2 is expecting a Child2.Msg,
but is instead receiving a Child1.Msg.
Model Child2
---
model =
{ id: Int
, name: String
, description: String
}

Re: [elm-discuss] Re: Import module from src directory in elm-repl
Hi Nick! I got curious when you said that you couldn't reproduce the problem so I tried to do the same in another folder, and I was unable to reproduce the problem as well. After spending some time in my main project, removing lines to narrow down the problem, I managed to get my main project to work with the repl! I'm still not sure what broke and why, but it seems it got fixed when I removed the elm-stuff folder. I suppose there were some cache somewhere screwing with the repl :/ Thank you all for trying to help! On Saturday, May 28, 2016 at 4:45:27 AM UTC+9, Nick H wrote: > > Three questions: > > 1.

Re: [elm-discuss] Is Msg a type or a type constructor?
Msg is like the Int in your description, it is a concrete type. `Html` and `Sub` are type constructors that take `Msg` and produce concrete types.

I need to update 2 child components based on the Action/Msg of 1 child
component. How would I do this?
The UpdateFromChild1 contains a Child1.Msg, which contains an id. I'd
like to send the id to the models of Child1 update *and* to Child2
update.
Code:
Main update
---
update msg model =
case of msg
UpdateFromChild1 msg ->
Child1.update msg Child1.model < works, update gets correct
message with id
Child2.update *msg* Child2.model < does not work, obviously
^-- somehow change this to
(Child2.Msg id)?
UpdateFromChild2 msg ->
-- stuff only child 2 cares about
Main view
---
view model =
div []
[ App.map UpdateFromChild1 (Child1.view Child1.model)
, App.map UpdateFromChild2 (Child2.view Child2.model)
]
