maybe let me try that
2019-02-16T10:14:27.568100

Well with the command you ran the index.html should be generated for you. I was wondering if it was actually output
2019-02-16T10:14:57.569200
Regenia
elmlang

wow.. no html markup when i view source
2019-02-16T10:16:24.569400
Leopoldo
elmlang
general
Okay there might just be an bug in the source it sometimes happens. Did you install elm-live in your project using npm or globally?
2019-02-16T10:17:36.571000
Regenia
elmlang
general
yes i did
2019-02-16T10:17:50.571200
Leopoldo
elmlang

Locally or globally?
2019-02-16T10:18:04.571700
Regenia
elmlang
general
npm -g
2019-02-16T10:18:13.571900
Leopoldo
elmlang

ok, i m getting somewhere
2019-02-16T10:18:21.572300
Leopoldo
elmlang
general
`Cannot GET /pages`
2019-02-16T10:18:39.572900
Leopoldo
elmlang
general
So in your project files was the index.html created now?
2019-02-16T10:19:32.573800
Regenia
elmlang
general
yes,
2019-02-16T10:19:46.574000
Leopoldo
elmlang
general
apparently the index file is created but i believe the error is from communicating the rest server
2019-02-16T10:20:14.574200
Leopoldo
elmlang
general
the server is able to output the result,
2019-02-16T10:22:00.574400
Leopoldo
elmlang
general
but i don't know why i m having error here
2019-02-16T10:22:15.574700
Leopoldo
elmlang
general
Okay so is the error happening on the root url or when you are trying to navigate to another url in your project?
2019-02-16T10:22:46.575700
Regenia
elmlang
general
on the root url i have a `file not found` error but to another error, i have a `Cannot GET /pages` error
2019-02-16T10:23:37.575900
Leopoldo
elmlang
general
do i have to fetch data from the `Model` or `Page` ? <https://gist.github.com/afidegnum/6192caed9ff5cf85e50d441d1fe269f4#file-main-elm-L445-L452>
2019-02-16T10:25:52.576200

any insight? consistently facing a `file not found` on elm-live
2019-02-16T11:02:16.577000
Leopoldo
elmlang

You don't have a `main` function in your module, so no JS file is even generated
2019-02-16T11:05:00.578600
Lynne
elmlang
general
Okay don't have to time to go through that all right now, but one thing I would do to make sure it is a code problem not an elm-live problem is try running your project in elm reactor and if you are getting the same issues it would be a code issue and you could start and new thread in the help channel to focus on that. :blush:

elm reactor ?
2019-02-16T11:06:06.579800
Leopoldo
elmlang
general
I m using `Main.elm`
2019-02-16T11:06:24.580300
Leopoldo
elmlang

It has to expose `main` function for the runtime to run it
2019-02-16T11:06:48.580700
Lynne
elmlang

give me an example

2019-02-16T11:07:19.581100

this is what i have done `module Main exposing (..)`
2019-02-16T11:08:41.581500
Leopoldo
elmlang

On this gist there is no `main` function in the `Main` module: <https://gist.github.com/afidegnum/6192caed9ff5cf85e50d441d1fe269f4#file-main-elm-L445-L452>
2019-02-16T11:09:20.581800
Lynne
elmlang

It does not matter that you wrote `exposing (..)` if there is no function it can't be exposed
2019-02-16T11:09:38.582200
Lynne
elmlang
general
wow! lol
2019-02-16T11:12:34.582400

ok, it's working now, as suggested adding `main` works

request successfully gone and response fetched but they are not loaded into the view. <https://gist.github.com/afidegnum/8ec22478549ceef6e6d4a7b0f8d0ae80#file-main-elm-L405-L700>
2019-02-16T11:33:47.583500

elmlang

and also requests are sent multiple times i don't understand why
2019-02-16T11:42:06.583900
Leopoldo
elmlang
general
<@Leopoldo> I'd check if the same Msgs fire multiple times. (ie. with `update msg model = case Debug.log "msg" msg of ...`)
2019-02-16T11:44:02.584600
Florencia
elmlang

if ie. SubmitNewPage fires multiple times, that would send the request multiple times.
2019-02-16T11:44:22.585000
Florencia
elmlang
general
yes, i believe that could be an issue but it supposed to be when a new event occured,
2019-02-16T11:45:09.585800
Leopoldo
elmlang

but fetchlist should fetch requsts once.
2019-02-16T11:45:27.586400

<@Florencia> where do i place the Debug.log ?
2019-02-16T11:46:49.587400

in the `case msg of` in update
2019-02-16T11:47:20.587600

How do you folks remember the order of `foldl` / `foldr`'s lambda? (ie. `newVal acc` or `acc newVal`)
2019-02-16T15:35:05.595900
Florencia

I always have to look it up
2019-02-16T15:35:14.596100

In Elm, "the thing being modified" is usually last, for pipeline-friendliness
2019-02-16T15:49:03.596800
Huong

so `v -&gt; acc -&gt; acc` :shrug:
2019-02-16T15:49:55.597700
Huong
elmlang
general
Right, kinda makes sense, even though I wouldn't mentally connect that lambda with pipeline-style functions. But yeah, it's adhering to a language-wide convention. Thx!
2019-02-16T15:52:51.599900
Florencia
elmlang
general
Yeah, for some reason, I occasionally visualise folds as long pipelines with the values being folded over being the argument on consecutive lines. So `List.foldl f acc [ 1, 2, 3 ]` becomes `acc |&gt; f 1 |&gt; f 2 |&gt; f 3` :smile:

Modesto
elmlang

So, in this case the numbers were different because `List.product` and `List.foldr` start from different sides (`List.product` uses `List.foldl`) and in this extreme case (big numbers) the associativity law breaks down. JS numbers are floats under the hood.
2019-02-16T16:15:39.609500
Florencia
elmlang
general
most libraries' approach to "what to do when you the numbers get really big or really small" is "don't care" - that's a possibility for you too. Just use the operators you've been given and inherit their weaknesses

How can I decode html page? I'm writing a simple blog that internally grubs posts from some urls. For some reason Http.get gives html rather than plain text (`Accept: text/plain` doesn't help), so I guess html decoding might do the thing, though quite painfully

maybe you will have luck with parsing the HTML as XML but I'm not sure it would work. Anyways, the XML packages have more tooling (decoders etc.) around than the HTML one

the expression on the right of (::) needs to be a list, so wrap the entire list.map expression in parenthesis or use (&lt;|)
