Method Detail

• applyHierarchyTemplate

   abstract Unit applyHierarchyTemplate(KotlinHierarchyTemplate template)

  Applies a given template to the project.

  Examples:

  • Manually apply the default hierarchy (See KotlinMultiplatformExtension.applyDefaultHierarchyTemplate):

  kotlin {
      applyHierarchyTemplate(KotlinHierarchyTemplate.default)
      iosX64()
      iosArm64()
      iosSimulatorArm64()
      linuxX64()
      // ...
  }

• applyHierarchyTemplate

   abstract Unit applyHierarchyTemplate(KotlinHierarchyTemplate template, Function1<KotlinHierarchyBuilder.Root, Unit> extension)

  Similar to applyHierarchyTemplate, but allows extension of the provided template.

  Examples:

  • Add custom groups (Experimental) to additionally share code between Linux and Apple (unixLike):

  kotlin {
      applyHierarchyTemplate(KotlinHierarchyTemplate.default) {
          group("native") { // <- we can re-declare already existing groups and connect children to it!
              group("unixLike") {
                  withLinux()
                  withApple()
              }
          }
      }
  }

• applyHierarchyTemplate

   abstract Unit applyHierarchyTemplate(Function1<KotlinHierarchyBuilder.Root, Unit> template)

  Allows creating a fully custom hierarchy (no defaults applied).

  **Note: ** Using the custom hierarchy requires setting the edges to 'commonMain' and 'commonTest' SourceSets by using the common group.

  Examples:

  • Share code between iOS and JVM targets:

  applyHierarchyTemplate {
      common {
          withJvm()
          group("ios") {
              withIos()
          }
      }
  }

  This configuration creates two KotlinSourceSetTree using the 'common' and 'ios' groups, applied on the "test" and "main" compilations. When the following targets are specified:

  • jvm()

  • iosX64()

  • iosArm64()

                         "main"                               "test"
                       commonMain                           commonTest
                           |                                    |
                           |                                    |
                +----------+----------+              +----------+----------+
                |                     |              |                     |
              iosMain               jvmMain        iosTest               jvmTest
                |                                    |
           +----+-----+                         +----+-----+
           |          |                         |          |
      iosX64Main   iosArm64Main            iosX64Test   iosArm64Test

  • Create a 'diamond structure'

  applyHierarchyTemplate {
      common {
          group("ios") {
              withIos()
          }
  
          group("frontend") {
              withJvm()
              group("ios") // <- ! We can again reference the 'ios' group
          }
  
          group("apple") {
              withMacos()
              group("ios") // <- ! We can again reference the 'ios' group
          }
      }
  }

  In this case, the group "ios" can be created with 'group("ios")' and later referenced with the same construction to build the tree. Apply the descriptor from the example to the following targets:

  • iosX64()

  • iosArm64()

  • macosX64()

  • jvm()

  To create the following 'main' KotlinSourceSetTree:

                           commonMain
                                |
                   +------------+----------+
                   |                       |
               frontendMain            appleMain
                   |                        |
         +---------+------------+-----------+----------+
         |                      |                      |
      jvmMain                iosMain               macosX64Main
                                |
                                |
                           +----+----+
                           |         |
                     iosX64Main   iosArm64Main
