Intellij syntax error: "Application does not take parameters"

Hello, I’m wondering if there’s a way to get IntelliJ (I’m using v15.0.6 with Scala plugin 2.2.0) to be able to recognize the implicit conversion to a Mapper when applying an Endpoint.

Screenshot:

The reported error is “Application does not take parameters”. Of course, this error is spurious (the code compiles). IntelliJ just seems to have some trouble with the conversion of my functions to Mappers (and probably also to FnToProduct). Not sure if this is a common issue for people using Finch in IntelliJ. Any help would be greatly appreciated!

I went ahead and filed an Intellij ticket (against Scala plugin): SCL-11386.

Thanks @chrisbenincasa!

I’m (and I think everyone else is) aware of this problem. One workaround I use is to disable type-checker in IntelliJ (hit that green [T] in the right bottom corner). Although, this basically disables the everything in the IDE besides autocompletion. I think the best we can do here is to file a ticket against the Scala plugin (and vote it!) and mention this problem as false-alarm. They usually respond quite promptly.

I personally nearly hate this “magnet pattern” thing we use as Mapper to allow this DSL-like syntax. I have some ideas how to make it more explicit (extract the syntax layer into its own namespace) and perhaps simplify. Although, this doesn’t mean IntelliJ shouldn’t support this pattern. Lots of Scala libraries use it and I think, the Scala plugin is making a quite a decent progress in better supporting it.
