    Great! Thanks to you for giving this valuable feedback!
    Good luck there :)

    @NickSeagull if you have time you should consider submitting a paragraph or two on Haskell.do to the HCAR
    the first deadline's closed now but Mihai gave all the authors 4 more days for proofreading the draft

    Great! Thanks @ocramz ! 😁

    Hi all
    I've started tinkering with the code, with a mind to write a miso-based frontend
    but I have some doubts regarding the overall design and I figured this would be the place to discuss
    so on one hand we have typical cabal/stack projects: multiple files in multiple directories, with dependencies forming a DAG
    on the other, the notebook-style interaction: evaluate a cell, show results, evaluate another cell etc.
    Marco Zocca
    @ocramz
    is the "cell view" just a split view of a single source file, and every time we modify one cell a stack build is issued? or something equivalent to a stack build --file-watch is constantly running?
    Marco Zocca
    @ocramz
    something else confuses me
    in miso, where do startApp and the App type come from? they are seemingly not exported by the library
    Nick Tchayka
    @NickSeagull
    Hi @ocramz , right now there is no cell view, its just a whole document that uses the inliterate preprocessor
    Basically a stack build is issued each time
    And also, Miso is quite weird, because those functions are only exported in the GHCJS version of it, not on the regular GHC one
    So we would have to separate completely the backend from the frontend
    Shoudlnt be that hard tho
    Marco Zocca
    @ocramz
    ha, what I suspected
    now I'm trying to write a bare-bones project to figure out what goes where
    I do like miso because M-V-C are well separated
    though I'm completely ignorant re. frontend development
    Marco Zocca
    @ocramz
    I feel miso is a very good choice to refurbish the project
    Nick Tchayka
    @NickSeagull
    Indeed it is @ocramz . Another thing that I was thinking of was to completely rewrite the backend and make it a RESTful API using some other framework like wai or yesod which are much more used in the Haskell community
    Marco Zocca
    @ocramz
    @NickSeagull what functionality would you put in the backend? the filesystem browser?
    I'm having a good experience with miso but I don't get why certain IO doesn't work, for example listing a directory
    so I wonder if it's a good idea to move that to a pure GHC backend
    once I figure this out I'm ready to help with the haskell-do refactor

    I was trying to figure out what miso is without digging into the code. What is it supposed to do?
    Marco Zocca
    @ocramz
    @dataopt it lets you write both the visible part and the behaviour of a single-page application
    in the "model-view-controller" style, i.e. a finite state machine
    the model is the state, buttons and whatever inputs are the controller and view is the visible part of this

    @NickSeagull
    @ocramz I would basically put the filesystem browser, compilation, save file, etc...

    @ocramz would be interested in what you might have in mind.
    I've been thinking to put a websocket in chart-unit for a while now, then luna came along, and now I want to try something like that out.
    I imagine it's beyond svg, so would have to learn about front-end and canvas, and miso might wrap it all up nicely.

    @tonyday567 you might check the transient gitter for some of @agocorona 's latest notes on that.
    Marco Zocca
    @ocramz
    @tonyday567 you're thinking of reactive/interactive graphics? I'm afraid I don't have any experience with those. Javascript callbacks into Haskell sound gnarly, but I'm the least qualified here to say this
    Marco Zocca
    @ocramz
    Can;t keep up with all the wonderful things built by @agocorona
    thanks Tim!

    @o1lo01ol1o
    I know, right?
    now if only I could get spacemacs and dante working with nix + ghcjs . . .
    Nick Tchayka
    @NickSeagull
    What do you have in mind @tonyday567 ? I had an idea like that before, and I have a couple of ideas to make callbacks work somehow
    Tony Day
    @tonyday567
    I haven't been tracking the transient gitter, but will dip in
    @NickSeagull have you seen the luna gui? chart-unit is fairly friendly for text placement - no wrapping tech etc but you can place text in the same way as any other chart element.
    Tony Day
    @tonyday567
    My idea is bubbles. You color code bubbles with type information inside, and when types agree, are compatible, they click together, lol. And then you draw a chart if it's a bunch of numbers
    Nick Tchayka
    @NickSeagull
    Yeah, I've used luna, but I'm not sure where you want to go by having bubbles :sweat_smile:
