it makes sense @antonicg but it makes sense over the 0.11 branch so instead of going to IO<A> it raises the invalid case on E for IO<E, A>

Validated is already on the classpath because fx depends on core

@dnowak et al, What would you like a polyadic function look like in Kotlin where it expands to a N parameters maybe up to 22 automatically in codegen so we can  eliminate all we are doing in function syntax, parMapN and other places which is the same problem?

Morning guys! are there plans to take arrow core into the kotlin multiplatform world?

Morning! Yes, absolutely. We’re currently blocked by kapt, and java impl in

fx

but soon both can be solved 🙂 Arrow Meta can replace the need for

kapt

, and I’ve found a different encoding for

fx

that doesn’t bind us to the JVM 🙂

Also we have the same goal for all other Arrow libraries, not just for core! Hopefully it can still land this year

ok, in this case I would like to help, we are currently planning to use it in production :D

what do I need to read/learn etc??

do we have any guide for contributors?

There are a bunch of good first issues collapsed into this epic for first-time contributors or those who want to start contributing to Arrow Meta. Those issues concern how Arrow Meta registers extensions in the Ide. https://github.com/arrow-kt/arrow-meta/issues/663 😄 Feel free to ping me if there are any questions. Have a nice weekend!

I know the difference between

Try

and

IO

and I know in which context I should use each of them.

I know that you want to promote “better” way of programming but there are cases when you really want to run some code that may explode synchronously and wrap the result in some structure that allows you to process it nicely.

Removing

Try

is like removing knives because people can cut themselves 😉.

yes, we are also planning on removing IO

the same laws and operators can now be implemented over suspend thanks to @simon.vergauwen

Looks like we will have a lot of code to rewrite… We use IO a lot in our projects 🙂

It will remain but moved to another module so you don’t have to migrate all at once

and it’s compatible with suspend 100% both ways

First attempt with the new Fx DSL... No surprise 👏 Ref & MVar still depend on Async/MonadDefer: Next step: try to mix F (e.g. Ref) with the new DSL... Are you planning to break these dependencies ?

No surprise is good, right?

Ref is called Atomic

This looks amazing 😍

Hey @tavish pegram, Awesome! We love all and any contributions, but we should do a better effort at adding and labeling tickets.. There is a couple of tickets for Arrow-Optics, but I think there is some room for improvement in the encodings. So if you're looking into Optics and find anything you think is worth refactoring, be sure to shoot up a ticket or create a PR! I'll try to add some more tickets there, in the following week 🙂 We also want to replace kapt with arrow meta, which also doesn't have a ticket. Beside that there is 2 project towards 0.11.0. https://github.com/arrow-kt/arrow-core/projects/1. In Arrow Fx we're currently focusing on finishing Arrow Fx Coroutines & Streams. Currently the biggest things there are tests, and documentation. All help there is welcome, but we also need to organise ourselves since we've made this big change from

IO

to

suspend

last month. All contributions are welcome, and I'm happy to help with anything along the way! & that counts for everyone reading this message 😉arrow

Hello everyone, I have a personal problem that I want to bring to you all.

I have been fooled by John de Goes in the last 3 years and at last he has shown to me he is not a respectable person.

I had invited him in the past to join Arrow.

We met in person and I took a long drive to meet him and discuss over Arrow and Zio to Malaga. We had a nice conversation. He has done wrong to me in the past before this multiple times for reasons I’m not gonna bring up here since it’s not relevant to this community.

I just want to let you know that if he ever shows up and you prefer him to stay I will leave.
