Syntax Multiplatform Support

A glue code used by KMP expects-compiler-plugin to bind an expect declaration with its actual implementation for JVM/WasmJs targets in JPS projects.

Usage:

common source root:

kotlin

fun myFunction(param1: String, param2: String): String = linkToActual()

jvm source root:

kotlin

@Actual
fun myFunctionJvm(param1: String, param2: String): String {
  // JVM implementation
}

WasmJs source root:

kotlin

@Actual
fun myFunctionWasmJs(param1: String, param2: String): String {
  // WasmJs implementation
}

Registration of expects-compiler-plugin in your module

Your iml file must mention the following fragment in Kotlin facet:

xml

<facet type="kotlin-language" name="Kotlin">
  <configuration version="5" platform="JVM 1.8" allPlatforms="JVM [1.8]" useProjectSettings="false">
    ...
    <arrayArguments>
      <arrayArg name="pluginClasspaths">
        <args>$MAVEN_REPOSITORY$/jetbrains/fleet/expects-compiler-plugin/<$$$real-version-here$$$>/expects-compiler-plugin-$$$real-version-here$$$.jar</args>
      </arrayArg>
    </arrayArguments>
    ...
  </configuration>
</facet>

Removal notice

TODO: Eventually, this module should be removed in favor of fleet.util.mutltiplatform. Right now it's impossible because fleet.util.mutltiplatform must be compiled with at least Java 10 (to make it compatible with JPMS), but some IntelliJ modules require Java 1.8.
