I was looking at codecov error and it's really weird - it tries to download codecov.yml. Are you sure there aren't any settings related to that in webui?

Commented on the PR. I like it but I have concerns about claiming these names as such as high level without indicating they are lenses.

A potential easy one for people wanting to contribute and learn more about Arrow https://github.com/arrow-kt/arrow/issues/854

Hi guys, I'm having presentation about optics and I need a catchy name. What do you think about: "Mutate the Immutable - Introduction to Optics"

Hey @simon.vergauwen it seems that new generated class is not included in the classpath and ank doesn't find it https://github.com/arrow-kt/arrow/pull/908#issuecomment-401133047 has something changed in that regard?

You can only define such a function once due to erasure

Try with dummy parameters with default values at the end

Damn, there so many issues with this kapt. kaptTestKotlin is not invoked when tests are run from IDE.

What anonymous classes do you mean? In the

invoke

overload?

We pushed for it to be a complete replacement of

Try

, but it didn’t stick 😕 Only thing we can do is promote the right usage.

Now then, what if we added

Kind

as a builtin?

@tginiotis indeed, that's our next step. This was a change in the frontend of the Kotlin compiler so that it is able to parse correctly the new syntax. Now we have to work on giving this syntax proper semantics; in this case, parameters with the

with

modifier are resolved at compile time with the appropriated instance and brought to the scope, so that the

with(MA) { }

would be no longer necessary

If so, then it definitely will

tomasruizlopez

09/10/2018, 12:51 PM

Yes, it will. The exact syntax would be with the modifier in each parameter that needs to be resolved with a typeclass instance, e.g.:

fun <A> something(with t1 : Typeclass1<A>, with t2 : Typeclass2<A>)

https://github.com/arrow-kt/arrow/pull/1031 so we can use Arrow for arrow-meta and to build Arrow itself.

Thanks Jacob. I am aware of that. The diagnose is exactly as you mention in the issue. The static analysis doesn't take into consideration what we are doing in the implicit resolution algorithm, and so, it marks the class as unused. AFAIK, this is also the case in Scala with implicits. But in any case, it is something that we need to address properly.
