[elm-discuss] Scrolling to bottom of div

[Wayne Choi]

I want to scroll down to the bottom of a div for, what else, a chat app. 
Right now I'm using element.scrollTop = element.scrollHeight  and it works 
fine with just javascript and html. Once I port the div to Elm, however, 
the function doesn't scroll all the way down. Am I missing something with 
how javascript interacts with the virtual dom? Is there an alternative 
solution?

Yeah, it took me a bit to get my head around it but I really appreciate how 
elegant the solution is.

[elm-discuss] Re: How do I organize "inheritance" between my data types?

[Evan]

Both Max and Aaron PS suggested using extensible records for this scenario, 
but I don't think that is the right way to go. It is particularly tempting 
for folks who want Elm to just work like an OO language, but it isn't like 
that. I think Tessa put it very nicely in her post 
: 
extensible 
records are for making functions flexible, not for modeling your data. I 
highly recommend OP and the folks who suggested extensible records read 
that post!

I believe Tessa's 
 and 
Aaron Vonderhaar's advice will get you to better code that is easier to 
understand and refactor.

It may help to watch this talk on modeling from a functional programming 
perspective (features F#, but applicable to Elm since they both are 
ML-based):

I recreated your example without issue, so I wonder if there is another

Re: [elm-discuss] What is the Elm-way to update a nested record field?

[Peter Damoc]

If you talk about explicitly updating each level then yes, that's still the
best approach.
You break your models into components and update each component as per Elm
Architecture.

If you talk about Focus, then no, I have not seen that really used.

you could do update functions like this:

updateLeftX x ({left} as model) =
   { model | left = {left | x = x} }

but it is better to have something like

updateLeftX x model =
{ model | left = Point.updateX x model.left}

Re: [elm-discuss] Re: Svg.image not showing when embedded inside HTML

[Peter Damoc]

Wow, changing

attribute "xlink:href" imgData

to

xlinkHref imgData

solved the issue. Which was a little bit weird because the output code
looks identical.

With this occasion I also found out about attributeNS, which might come in
hand. ;)

Thank you Iwan!

Actually, Elm is appealing to Elixir developers, not the other way around 
;) 
A lot of the talk you see around Elixer in Elm's discussion forums seems to 
be from Elixer developers who have found Elm to be a useful front-end 
solution.
Elm on the backend is ultimately the way to go.

Re: [elm-discuss] Port Error

[Duane Johnson]

Where is `subs` coming from? I see it used in the onEffects function, but I
don't see its definition.

[elm-discuss] Svg.image not showing when embedded inside HTML

[Peter Damoc]

Hello kind people,

I've been struggling with an issue and maybe one of you has an insight on
what else could I try.

Here is the SSCCE:
https://gist.github.com/pdamoc/53a312e7bb3d08b256a2afb3a584661f

*The problem:*
I try to display an image embedded as base64 inside a SVG (the final
purpose is to print it.)
The image does not show when I try to display the resulting SVG.

The strange thing is that when I send the contents of the "output" div to a
new window, the image shows. If I manually copy the resulting html (via the
dev tools) into a plain html file, again, the image shows.

I've tried it on Chrome, Firefox and Safari and the behavior is consistent.

I've validated the output html that elm-make creates and it is 100% valid.

I've even tried to put the resulting SVG into an iframe but the iframe came
out blank.

What else can I try?

Thank you in advance.

[elm-discuss] Port Error

[Zachary Kessin]

I am having a strange problem with ports, I am trying to send a list of
data through the port (see gist) and I it is giving me a runtime error.

Actually it seems to have nothing to do with the data, as I am trying to
send a string through a different port in the same file and getting the
same error.

Some ports in other files work ok
