How to create a Functor for an ADT used in a cats Free Monad

Asked 2021-May-25 at 14:41

I am writing a DSL using case classes with the help of the cats.free.Free Monad library. The DSL is to be interpreted by Actors receiving the message, so each actor has to first unwrap a command using Free.resume.

This worked out nicely six years ago using scalaz where we also used the resume function too, but the Functor for the free monad was easy to create as we used case classes that came with an extra function argument that could be mapped over such as k below.

The problem is in your data type: Get[T] does not use T, so cannot map this meaningfully, other than a no-op: g: Get => Get[B](g)

SBT multi-project build : 2 different versions of sbt play plugin for different subprojects

Asked 2021-Mar-13 at 09:45

I have an sbt project containing 2 play sub-projects with 2 different versions of play (and basically 2 different versions of Scala: 2.12 and 2.10). Is there a way to use two versions of the play plugin? This is my plugins.sbt:

Answered 2021-Mar-13 at 09:45

To sum up the discussion from the comments, it is probably impossible. One of the difficulties for example is to enable PlayScala in build.sbt. As described in The /build.sbt file (version 2.8) or at Auto Plugins and plugin settings (version 2.3), in both versions you enable the plugin:

Asked 2021-Jan-19 at 17:48

How can an Iterable of Try values be converted into a Try of Iterable? If the Iterable contains a failure then the first Failure should be returned, if there are no failures then an Iterable of the Success values should be returned.

As an example, assume the conversion function is called squash:

You seem to be using a scratch file. AFAICS, there is no way to also include dependencies from your Test scope into the classpath of your worksheet.

A workaround would be to (temporarily) add the play-test artefact to your libraryDependencies. Or just create a proper test file, which has access to the Test libraries normally.

rxjava3-extensions:3.0.0-RC7 is not compatible with rxjava:3.0.3. Release candidates don't provide strict compatibility guarantees.

Upgrade to rxjava3-extensions:3.0.0 or up.

For future reference NoSuchMethodError almost always indicates incompatible libraries. The unfound method in the exception message and the method at the top of the stacktrace are good indicators of which libraries are involved.

I was calling the wrong method. The openApiGenerators just list the generators which is what it was doing. To generate the output, you have to call the task created above openApiGenerate. Thanks @philonous for the answer.
