Scala Native v0.3.7 Release Notes

Release Date: 2018-03-29 // about 6 years ago

  • 🚀 This release focuses on stability and compatibility improvements, keeping backwards binary compatibility with previous releases in 0.3.x series.

    🆕 New build tool API 🏗️

    🏗 Scala Native has supported integration with sbt build tool since day 1, but it was also the only official way to compile and link applications until now.

    🚀 In this release we provide a new API aimed at simplifying integration of Scala Native toolchain with 3-rd party build tools (e.g. Maven, Mill) and compilation servers (e.g. Bloop). Reference integration requires just under 30 lines of code to run the whole Scala Native pipeline, LLVM and link it all to the final executable.

    👌 Improved cross projects 🎌

    (Contributed by @sjrd)

    🚀 Scala Native cross projects have been born as a generalization of Scala.js 0.6 cross projects. Since original release as scala-native/sbt-crossproject, the project has moved to portable-scala organization which contains projects shared between Scala.js and Scala Native. The API remains fully compatible with previous iteration, and one just needs to update plugin dependencies to migrate (see README for instructions).

    ➕ Additionally, updated cross projects contain an ability to remove suffix for one of the platforms. For example:

    lazy val bar = crossProject(JSPlatform, JVMPlatform, NativePlatform) .withoutSuffixFor(JVMPlatform) .crossType(...) .settings(...)lazy val barJS= bar.jslazy val barJVM= bar.jvmlazy val barNative = bar.native

    Now JVM project ID is just bar and can be used without a suffix in sbt shell (i.e. bar/compile would compile JVM subproject).
