@pakoito Thank you very much for the advice. It always pays back to read the whole documentation of the library you are using 🙂. flatTap is what I was looking for.

We use IO<Either<E, R>> a lot so we use EitherT a lot too. Is there any way to provide IO<B> to EitherT’s flatTap? The compiler insists on IO<Either>, so I ended up with this snippet:

[dnowak]

.flatTap(IO.monad()) { events ->
                        EitherT(IO
                                .effect { logger.debug { "Leger: <$ledgerId> has events: <$events>" } }
                                .map { Unit.right() })
                    }

yikes

[pakoito]

it looks correct

[pakoito]

so in 0.11 we'll have IO<E, A> and you won't need EitherT

[pakoito]

0.10.5 is the last release of that series

[dnowak]

I will try to hide it in extension function.
I can’t wait to use 0.11 🙂
