/* Note [Engine And Launcher Version]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 * Currently both Engine and Launcher versions are tied to each other - each new
 * releases contains the Engine and the Launcher and thus the version number is
 * shared. If the version numbers ever diverge, make sure to update the build
 * scripts at .github/workflows accordingly.
 */

/* Note [Default Editions]
 * ~~~~~~~~~~~~~~~~~~~~~~~
 * Currently, the default edition to use is inferred based on the engine
 * version. Each Enso version has an associated default edition name and the
 * `currentEdition` field specifies the default edition name for the upcoming
 * release.
 *
 * Thus the `library-manager` needs to depend on the `version-output` to get
 * this defaults from the build metadata.
 *
 * In the future we may automate generating this edition number when cutting a
 * release.
 */

/* Note [Standard Library Version]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 * Currently the Standard library version is fixed at 0.1.0.
 *
 * Once the library repository is up and we start releasing the libraries, this
 * version will need to be bumped, so for now the best way to achieve that will
 * be to keep it in-sync with the engine version. However this will require
 * creating a tool which will bump these version numbers in all standard library
 * packages.

/* Note [Classpath Separation]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~
 * Projects using the language runtime do not depend on it directly, but instead
 * the language runtime is put on the Truffle classpath, rather than the
 * standard classpath. This is the recommended way of handling this and we
 * strive to use such structure everywhere.
 * See
 * https://www.graalvm.org/docs/graalvm-as-a-platform/implement-language#graalvm
 *
 * Currently the only exception to this are the tests of the runtime project
 * which have classpath separation disabled, because they need direct access to
 * the runtime's instruments.
 *
 * To ensure correct handling of dependencies by sbt, the classpath appended to
 * Java options, should be based on `(runtime / Compile / fullClasspath).value`
 * wherever possible. Using a key from the runtime project enables sbt to see
 * the dependency.
 *
 * Assembly tasks that build JAR files which need `runtime.jar` to run should
 * also add a dependency on `runtime / assembly`.

/* Note [Unmanaged Classpath]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~
 * As the definition of the core primitives in `core_definition` is achieved
 * entirely using the graph macros, this means that the IDE experience for those
 * using these primitives is very poor.
 *
 * To get around this, we want to treat the core definition as a .jar dependency
 * to force the IDE to depend on bytecode for its diagnostics, rather than the
 * source code (as this means it sees the macros expanded). A standard workflow
 * with local publishing would not recompile the definition automatically on
 * changes, so the `unmanagedClasspath` route allows us to get automatic
 * recompilation but still convince the IDE that it is a .jar dependency.

/* Note [Native Image Workaround for GraalVM 20.2]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 * In GraalVM 20.2 the Native Image build of even simple Scala programs has
 * started to fail on a call to `Statics.releaseFence`. It has been reported as
 * a bug in the GraalVM repository: https://github.com/oracle/graal/issues/2770
 *
 * A proposed workaround for this bug is to substitute the original function
 * with a different implementation that does not use the problematic
 * MethodHandle. This is implemented in class
 * `org.enso.launcher.workarounds.ReplacementStatics` using
 * `org.enso.launcher.workarounds.Unsafe` which gives access to
 * `sun.misc.Unsafe` which contains a low-level function corresponding to the
 * required "release fence".
 *
 * To allow for that substitution, the launcher code requires annotations from
 * the `svm` module and that is why this additional dependency is needed as long
 * as that workaround is in-place. The dependency is marked as "provided"
 * because it is included within the native-image build.
 */

/* Note [WSLoggerManager Shutdown Hook]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 * As the WSLoggerManager registers a shutdown hook when its initialized to
 * ensure that logs are not lost in case of logging service initialization
 * failure, it has to be initialized at runtime, as otherwise if the
 * initialization was done at build time, the shutdown hook would actually also
 * run at build time and have no effect at runtime.
