lemme prototype your think now 😄

😮

EDIT OUT

that works for me on master

now, for the IO instance

oh nevermind

wait

that fx is actually the IO one

-.-

-.java

that’s the right one, 100% sure

easy ticket for first time contributors

Is there a bug in the FpToTheMax sample? (https://github.com/arrow-kt/arrow/blob/master/modules/docs/arrow-examples/src/test/kotlin/arrow/FpToTheMax.kt) It does not ask:

"Do you want to continue, $name?"

. However, if you change

val (_) = putStrLn("Do you want to continue, $name?")

to

putStrLn("Do you want to continue, $name?").bind()

it works.

it may just be outdated

…it’s doing it in the line below

can you try to give it a type or something?

do you mean val(_: Unit)?

binding

will go away in 0.9.1 when the Fx data type is ready

I am a beginner in Arrow. I have a question. Is it OK to implement the following when you want to cancel at the same time with

Arrow Fx

? I would like to know if CoroutineScope and other mechanisms can be used.

@takahirom welcome to Arrow!

Morning guys, I know...it's sunday...but I'm dealing with optics/lenses and I'm kinda stuck. I have a multi module project and for some reason I cannot access the optics companion generated code from one module to another. By building my own lenses though everything works fine:

@optics
data class SalesProductLine(val id: Int, val products: ListK<SalesProduct>) {companion object}

vs

val productLineLens: Lens<SalesProductLine, ListK<SalesProduct>> =
        Lens(
                get = { pl -> pl.salesProducts },
                set = { pl: SalesProductLine, products -> pl.copy(salesProducts = products )}
        )

productLineLens.every(ListK.each()) ... ....

What could it be the reason for not having the code generated by the optics annotation?

Did I miss something?

Hey @nicopasso. Is the code not generated or is it not accessible from another module?

If it’s not accessible from another module but the code is being generated then it sounds like some gradle issue

Might even be that you need to refresh IntelliJ to pick up the changes. (Manually triggering Gradle sync normally does the trick for me)

Can you check if the code is being generated? It should be under

module_path/build/generated/source/kaptKotlin/main/package_name

ah yea sorry. the code is not generated. I tried to decompile the kotlin file to see the Java generated code but there's no code related to Lenses
