a 25 minutes chat between Raul and I about how Arrow came through, and the things we’re working on 😄

I swear there were a couple of messages here a minute ago

Hah, yeah. Sorry to ping you, I saw the links at the end of your talk too late.

that's fine 😄

ye, exactly

Cool, thanks.

we also use it through Arrow in general

if you have any questions just ask 😄

One observation me and my colleagues often raise is that Arrow provides just about everything you need, but with the expectation that you already know moderate/advanced FP concepts. You mention in your talk that Arrow has everything a Scala or Haskell dev expects to be in their toolset. Do you guys have any plans to do more complete examples (e.g. a full featured app) for us who want to do full FP rather than FP-ish?

And by FP-ish I mean simply introducing some data structures (Either, Option, etc) to our existing codebase.

there are some longer examples in the libraries and examples sections of the docs

but that may not be enough

I try not to be prescriptive about architecture. I give ideas about how to structure things but in the end it's up to you do to MVI, MVVM, use lenses or deep updates etc.

and even among us we have opinions 😄 I like Rx streams end-to-end for example

whereas Raul and Jorge go by with regular IO and suspended functions

that example predates arrow, but shows the architecture of my latest Android app end-to-end

Cool, thanks.

@Jorge Castillo I don't know how much you can talk about your client's

almost nothing 😄

It sounds like if you want to do FP for UI apps, functional core / imperative shell is standard?

we’re supposed to work over Android blueprint projects for Arrow at some point

but that’s a TBD atm

for now feel free to post your problems here and we’ll try to help as much as we can

My FP experience has mostly been in CLI Haskell/Idris so I’m trying to figure out FP ways of doing UIs (Comonadic UIs) vs UI architectures (Cycle, Elm, etc).

that’s a super generic question, are we talking about a specific platform?
