scourt - Coroutines for Scala

Scourt is a Scala-3 compiler plugin that implements a form of coroutines for Scala.

BUILD NOTICE

The following projects have been unaggregated and must be compiled seperately and run with runMain:

• continuationsPluginExample
• zero-arguments-no-continuation-treeview
• zero-arguments-one-continuation-code-before-used-after
• list-map
• two-arguments-two-continuations

To run these projects, you must use runMain with the fully qualified name of the main.

$ sbt
root> continuationsPluginExample/runMain examples.ThreeDependentcontinuations

This is so that ci build will continue to work until sbt/zinc#1174 is merged and resolved.

Build and run in your local environment:

Pre-requisites:

• Java 19
• Scala 3

1. Download the latest Project Loom Early-Access build for your system architecture.

   This is easy to do if you are using SDKMAN. First list java versions with sdk list java, and sdk install java 19-ea-<XX>-open, where XX is the latest Java.net version 19 release number. Make it the default with sdk default java 19-ea-<XX>-open.

2. Set your JAVA_HOME to the path you extracted above.

Unnecessary if you have set the ea build to be your default in sdkman.

You can now compile and run the tests:

env JAVA_OPTS='--enable-preview --add-modules jdk.incubator.concurrent' sbt "clean; compile; test"

NOTE: The Loom project is defined as an incubator module that is a means to distribute APIs which are not final or completed to get feedback from the developers. You should include the -add-module Java option to add the module to the class path of the project.
