Is there a way to let custom sbt plugin discover which platform a Scala project targets?

I would like to develop an sbt-plugin that would auto-generate sources for Scala projects. The thing is I would like to produce slightly different sources for each targeted platform (JVM, Native, Scala.js).

Because of that, my plugin needs to detect the project platform. I wonder if there is an elegant way of doing that?

which kind of sources? Scala classes? – Tomer Shetah Dec 16 '20 at 11:13
Yeah, for my case these are Scala classes. – przemod Dec 17 '20 at 15:13
So basically your ask is how to know what platform is it from Scala code, right? – Tomer Shetah Dec 17 '20 at 16:19
Yep, from inside the sbt plugin. – przemod Dec 21 '20 at 14:22
It may be a long answer, but I would explore Scala Meta to parse the sbt config file and to generate new AST based on your platform. – Emiliano Martinez Dec 23 '20 at 09:45
@EmiCareOfCell44 Could you elaborate on it? How would parsing the sbt config help the generation task to know the type of project that this task is called for? – przemod Dec 28 '20 at 09:44
take a leek to https://github.com/portable-scala/sbt-crossproject.Maybe it can help – Emiliano Martinez Dec 28 '20 at 12:21
Hmm, in this case, the project might not even use the `sbt-crossproject` plugin. It might, for example, use only `ScalaJSPlugin` and compile itself only to the Scala.js platform. – przemod Dec 28 '20 at 14:49
