Arrow: Port Functional and Reactive Domain Modeling's examples to Arrow

[pakoito]

Someone on twitter suggested porting these: https://github.com/debasishg/frdomain-extras

[i-walker]

I suggest creating a new repo for this. Just like @arrow/Category-Theory...
Or do you intend to reimplement the aforementioned repo with arrow ?

[pakoito]

New repo would be okay. This issue is to keep track of the suggestion.

Hi, I have been following Arrow alot and also ZIO from Scalaz and I would like to learn both :-) Ive written frdomain extras with ZIO and are very much intrested in how Arrow solution would look like. I dont have the knowledge in Arrow yet so cant help out here unfortunately but would be very grateful if someone had the time and intrest in building an Arrow solution for Mr Gosh repo. Thanks in advance and if I can do anything to help, pls let me know. Regards Dan

We'll get someone, @danp11 !!

Do we have a repo? I already started and I can push some code. 😊

[pakoito]

I'll do it tonight!

Nice! :-) A while ago I found this post on Arrow twitter: https://github.com/pedrovgs/KotlinKatas/pull/4
and I thought that beautiful code nicely could replace part of this section: https://github.com/debasishg/frdomain-extras/blob/master/cats-io/src/main/scala/frdomain/ch6/domain/model/Account.scala

Im very new to FP but could give validation code a try that you later can correct or make better. Thats how one learn aint it :-)

I already have that one written... Gotta star with the model...

But I can leave out some stubs for you to implement 😉

[danp11]

Ok, If thats the case Id be more than happy just learn from your/others
implementation hehe:-) Ive seen your repo of "Hangman" and its very nice.
Excuse my lack of knowledge in Arrow/Kotlin but I red about the FX module
that came in 0.90 was it? and it would be very intresting to see that code
aswell as your Part 3 of that repo:-) Is there anything you have thought
of?

Thank you and have a nice weekend!

Cheers from Stockholm, Sweden

Hi again and I just wanted to say Thanks for the code and the time you've spent on this.

Its a very good source when one is new to a language/code style.

Regards
Dan

I'm glad you find it useful, but it's still not done. The Reactive Domain Modeling has the same code in 3 styles. The Arrow port at the moment only has IO (equivalent to cats-io). There are 2 styles left or maybe 3 after arrow 0.9.1 is out.

My plan is to start work on tagless final next. Any other contributors are welcomed.
