Support for Scala Native 0.5.1

This Scala CLI version adds support for Scala Native 0.5.1. All native platform builds will now use 0.5.1 as the default version.

scala-cli -e 'println("Hello, Scala Native!")' --native
# Compiling project (Scala 3.4.1, Scala Native 0.5.1)

# Hello, Scala Native!

Note that not all the tools Scala CLI integrates with support Scala Native 0.5.x just yet.
When such an integration is being used, the default Scala Native version will get downgraded to 0.4.17.

scala-cli -e 'println("Hello, Scala Native!")' --native --toolkit default
# [warn] Scala Toolkit does not support Scala Native 0.5.1, 0.4.17 should be used instead.
# [warn] Scala Native default version 0.5.1 is not supported in this build. Using 0.4.17 instead.

# [info] Total (4812 ms)
# Hello, Scala Native!

Efforts for supporting Scala Native 0.5.x are ongoing, we expect the downgrade to 0.4.17 in such cases to be a temporary solution.
If you know for a fact that 0.5.x support has been delivered for a tool, you can always pass the --native-version option explicitly, which will prevent the downgrade.

Scala 3.3.3, 3.4.0, 2.13.13 & 2.12.19 support

This version of Scala CLI adds support for a whooping 4 new Scala versions, it's been busy these past few days!
The default version used when using the CLI will from now on be the Scala 3 Next version (3.4.0 as of this release).
Using the lts tag will now point to Scala 3.3.3.
The LTS is also the version used for building the internals of Scala CLI (although we now also cross-compile with 3.4.0).

scala-cli version
# Scala CLI version: 1.2.0
# Scala version (default): 3.4.0

Added by @Gedochao in #2772, #2736, #2755, #2753 and #2752

Remapping EsModule imports at link time with Scala.js

Given the following importMap.json file:

{
  "imports": {
    "@stdlib/linspace": "https://cdn.skypack.dev/@stdlib/linspace"
  }
}

It is now possible to remap the imports at link time with the jsEsModuleImportMap directive.

//> using jsEsModuleImportMap importMap.json
//> using jsModuleKind es
//> using jsMode fastLinkJS
//> using platform js

import scala.scalajs.js
import scala.scalajs.js.annotation.JSImport
import scala.scalajs.js.typedarray.Float64Array

object Foo {
  def main(args: Array[String]): Unit = {
    println(Array(-10.0, 10.0, 10).mkString(", "))
    println(linspace(0, 10, 10).mkString(", "))
  }
}

@js.native
@JSImport("@stdlib/linspace", JSImport.Default)
object linspace extends js.Object {
  def apply(start: Double, stop: Double, num: Int): Float64Array = js.native
}

The same can be achieved with the --js-es-module-import-map command line option.

scala-cli --power package RemappingEsModuleImports.scala --js --js-module-kind ESModule -o main.js --js-es-module-import-map importMap.json

Support for LTS Scala version aliases

It is now possible to use lts and 3.lts as Scala version aliases in Scala CLI.
They refer to the latest LTS version of Scala (the 3.3.x line at the time of this release).

scala-cli run -S lts --with-compiler -e 'println(dotty.tools.dotc.config.Properties.simpleVersionString)'
# Compiling project (Scala 3.3.1, JVM (17))
# Compiled project (Scala 3.3.1, JVM (17))
# 3.3.1

Using the 2.lts, 2.13.lts & 2.12.lts aliases returns a meaningful error, too.

scala-cli run -S 2.lts -e 'println(scala.util.Properties.versionString)'                                 
# [error]  Invalid Scala version: 2.lts. There is no official LTS version for Scala 2.
# You can only choose one of the 3.x, 2.13.x, and 2.12.x. versions.
# The latest supported stable versions are 2.12.18, 2.13.12, 3.3.1.
# In addition, you can request compilation with the last nightly versions of Scala,
# by passing the 2.nightly, 2.12.nightly, 2.13.nightly, or 3.nightly arguments.
# Specific Scala 2 or Scala 3 nightly versions are also accepted.
# You can also request the latest Scala 3 LTS by passing lts or 3.lts.

Added by @kasiaMarek in #2710

--semanticdb-targetroot and --semanticdb-sourceroot options

It is now possible to set the SemanticDB target root and source root directories with unified syntax, independent of the target Scala and/or Java versions.

scala-cli compile src/semanticdb-example.sc --semanticdb-targetroot ./targetRootDir --semanticdb-sourceroot .

Deprecate Scala Toolkit latest version in favour of default

Using toolkits with the latest version is now deprecated and will cause a warning.
It will likely be removed completely in a future release.

scala-cli --toolkit latest -e 'println(os.pwd)'
# Using 'latest' for toolkit is deprecated, use 'default' to get more stable behaviour:
#  --toolkit default
# Compiling project (Scala 3.3.1, JVM (17))
# Compiled project (Scala 3.3.1, JVM (17))
# /home

It is now advised to either use an explicit toolkit version or rely on the new default alias.

scala-cli --toolkit default -e 'println(os.pwd)'
# Compiling project (Scala 3.3.1, JVM (17))
# Compiled project (Scala 3.3.1, JVM (17))
# /home

The default version for toolkits is tied to a particular Scala CLI version.
You can check which version is used by referring to Scala CLI help.

scala-cli version                 
# Scala CLI version: 1.1.1
# Scala version (default): 3.3.1
scala-cli run -h|grep toolkit         
#   --toolkit, --with-toolkit version|default  Add toolkit to classPath (not supported in Scala 2.12), 'default' version for Scala toolkit: 0.2.1, 'default' version for typelevel toolkit: 0.1.20

Breaking update to Scala 2 scripts

Keep in mind that it ONLY applies to Scala 2! Scala 3 script wrappers are not affected!

Scala CLI now uses a different kind of script wrappers for Scala 2 by default, which support running background threads.
This has been introduces as an answer to the issue #2470, where a running a script in Scala 2 would end up in a deadlock due to background threads being run.
Also the change makes the Scala 2 scripts run significantly faster, as the code can be optimized due to not residing in the object's initialization clause.

However, the new solution brings some incompatibilities with the old behaviour:

  • main classes are now named the same as the file they are defined in, they do not have the '_sc' suffix anymore, so any calls like:
scala-cli foo.sc bar.sc --main-class foo_sc

should be replaced with

scala-cli foo.sc bar.sc --main-class foo
  • it is impossible to access the contents of a script named main.sc from another script, any references to the script object main will result in a compilation error.
println(main.somethingDefinedInMainScript)

Will result in the following compilation error:

[error] ./foo.sc:2:11
[error] missing argument list for method main in trait App
[error] Unapplied methods are only converted to functions when a function type is expected.
[error] You can make this conversion explicit by writing `main _` or `main(_)` instead of `main`.

When main.sc is passed as argument together with other scripts, a warning will be displayed:

[warn]  Script file named 'main.sc' detected, keep in mind that accessing it from other scripts is impossible due to a clash of `main` symbols

Added by @MaciejG604 in #2556

"Drive relative" paths on Windows

Scala CLI now correctly recognizes "drive relative" paths on Windows, so paths like /foo/bar will be treated as relative from the root of the current drive - e.g. C:\foo\bar.
This allows for compatibility of programs referencing paths with e.g. //> using file /foo/bar with Windows.

Added by @philwalk in #2516

UX improvements

v1.0.6

Scala CLI won't default to the system JVM if it's not supported anymore

If your JAVA_HOME environment variable has been pointing to a JVM that is no longer supported by Scala CLI (so anything below 17, really), you may have run into an error like this one with Scala CLI v1.0.5:

scala-cli --power bloop exit 
# Stopped Bloop server.  
export JAVA_HOME=$(cs java-home --jvm zulu:8)
scala-cli -e 'println(System.getProperty("java.version"))'                
# Starting compilation server
# Error: bloop.rifle.FailedToStartServerExitCodeException: Server failed with exit code 1
# For more details, please see '/var/folders/5n/_ggj7kk93czdt_n0jzrk8s780000gn/T/1343202731019130640/.scala-build/stacktraces/1699527280-9858975811713766588.log'
# Running
#   scala-cli --power bloop output
# might give more details.

This is because we no longer support JVM <17 with Scala CLI v1.0.5, but we still have been defaulting to whatever JVM was defined in JAVA_HOME. As a result, Bloop has been failing to start when running with, say, JAVA_HOME pointing to Java 8.

This is no longer the case. Scala CLI will now automatically download Java 17 for Bloop in such a situation (and still use the JVM from JAVA_HOME for running the code, while Bloop runs on 17).

scala-cli --power bloop exit 
# Stopped Bloop server.  
export JAVA_HOME=$(cs java-home --jvm zulu:8)
scala-cli -e 'println(System.getProperty("java.version"))'                
# Starting compilation server
