Re: [elm-discuss] Re: Help with Jupyter/IPython notebook kernel for Elm

[Austin Bingham]

There isn't currently any elm-repl support, though there's an open issue
for it: https://github.com/abingham/jupyter-elm-kernel/issues/9

I'm not entirely sure how it should work, both from the user's perspective
or technically, so any ideas would be great.

very nice! just found this thread today... seems to install and run just

The basic kernel is working at this point, and you can get it here:
https://github.com/abingham/jupyter-elm-kernel

But there's still quite a bit to be done, and some of the design decisions
I made might be short-sighted. Take it for a spin and let me know what you
think. Any feedback, ideas, PRs, etc. would be great.

[Michael Lamb]

Are you still looking for a hand with this, Austin? 

I'm not an expert, or anything but I'm really interested in making a good 
Jupyter kernel for Elm to use with nteract. If you haven't seen it, check 
it out: https://nteract.io/
It mimics Jupyter as a desktop application, so you do not need a server.

Klipse looks interesting, but I'm hoping to use Jupyter to make a 
presentation so I'm going to stick with that for now.

Regarding Jupyter needing a server: there are places that host notebooks, 
so the server requirement is only partly true. Your point is a good one, 
though. Sometime the complexity of jupyter can seem a bit unwieldy.

[elm-discuss] Re: Help with Jupyter/IPython notebook kernel for Elm

[Berry Groenendijk]

Hi Austin,

I like Jupyter/iPython a lot as a concept. I did not use it a lot though. 
And Elm seems to be like a natural fit.

My dream would be to have live aka. living documents where static text and 
live code are intermingled. Jupyter is a step in the right direction. But, 
you still need a server.

Just recently I found a thing called Klipse, see: 
http://blog.klipse.tech/javascript/2016/06/20/blog-javascript.html. It 
looks a lot like Jupyter (minus the document editing, but that should be 
trivial), but all the code is executed in the browser! It currently has 
support for clojure, ruby, javascript, python, scheme, es2017, jsx, 
brainfuck, c++ and Lua. Quite impressive. And if javascript works, them Elm 
should also work. Perhaps it is already possible... import elm.js... 
hmmm... I don't know.

Sorry, if this post isn't directly related to Jupyter and your challenge to 
integrate Elm in Jupyter.

[elm-discuss] Re: Help with Jupyter/IPython notebook kernel for Elm

[Austin Bingham]

FWIW, I see that when the generated javascript is passed back to the 
Jupyter client, the client calls eval() on the javascript. This seems to 
work OK, insofar as it doesn't throw an exception. However - and this is 
where I'm a bit out of my depth - none of the bindings made in the 
javascript seem to be available in the calling context. Maybe this is the 
nature of eval(), but I'm not sure. The "ReferenceError" I reported 
initially seems to actually come from when I try to use the "Elm" object to 
embed the app in a DOM object.
