Hotfix release

Although Scala CLI 1.5.4 includes a few updates and improvements, it is primarily a hotfix release for versions 1.5.2 and 1.5.3, which due to technical limitations weren't available on some of our distribution channels.

Extra context:

The main list of enhancements and fixes is listed in the release notes for 1.5.2.

Support for Scala Native 0.5.6

This Scala CLI version switches the default Scala Native version to 0.5.6.

v1.5.3

This is a hotfix release, which makes all the fixes and enhancements of Scala CLI 1.5.2 available through most standard distribution channels (rather than just Maven Central).

For the main release notes, please refer to the v1.5.2 ones.

Distribution limitations

Due to technical difficulties within our release pipeline, Scala CLI 1.5.3 is not available via the following channels:

  • yum (on RedHat/Cent OS/Fedora)
  • SDKMAN!

We will follow up with a 1.5.4 hotfix release to address this issue.

Hot-fixes

  • Tag failing native packager tests as flaky by @Gedochao in #3270
  • Make publishing depend on all integration tests & docs tests by @Gedochao in #3272

Pre-release

Scala CLI 1.5.2 will only be available on the JVM

Due to technical difficulties with our release pipeline, Scala CLI 1.5.2 was only released as a JVM launcher on Maven Central. While it can be used as such, we will follow it up with a hotfix 1.5.3 release, which should be available through all standard distribution channels.

scala-cli --cli-version 1.5.2 version
# Scala CLI version: 1.5.2
# Scala version (default): 3.5.2

--source is now deprecated and scheduled for removal in Scala CLI v1.6.x

Due to how easy it is to confuse --source (the command line option for producing source JARs with the package sub-command) and -source (the Scala compiler option, which can also be passed as --source in recent Scala 3 versions), using the former is now deprecated, and will likely be removed in Scala CLI v1.6.x.

scala-cli --power package --source .                       
# [warn] The --source option alias has been deprecated and may be removed in a future version.
# (...)

Do note that the deprecation (and future removal) only affects the option alias.
The feature of packaging source JARs remains unchanged.
It is now recommended to switch to using the --src alias instead.

scala-cli --power package --src .

Added by @Gedochao in #3257.

Support for Scala 3.5.2

This Scala CLI version switches the default Scala version to 3.5.2.

scala-cli version
# Scala CLI version: 1.5.2
# Scala version (default): 3.5.2

Added by @Gedochao in #3230

Initial support for emitting Wasm with a command line option and a directive

It is now possible to emit Wasm via Scala.js with the //> using jsEmitWasm directive:

//> using platform js
//> using jsEmitWasm
//> using jsModuleKind es
//> using jsModuleSplitStyleStr fewestmodules
println("Hello")

Or with the --js-emit-wasm command line option:

scala-cli --power package wasm.sc --js --js-emit-wasm
# The `--js-emit-wasm` option is experimental
# Please bear in mind that non-ideal user experience should be expected.
# If you encounter any bugs or have feedback to share, make sure to reach out to the maintenance team at https://github.com/VirtusLab/scala-cli
# Compiling project (Scala 3.5.2, Scala.js 1.17.0)
# Compiled project (Scala 3.5.2, Scala.js 1.17.0)
# Wrote ~/wasm/wasm.js/main.js, run it with
#   node ./wasm.js/main.js
tree wasm.js
# wasm.js
# ├── __loader.js
# ├── main.js
# └── main.wasm
# 
# 1 directory, 3 files

For more information about Wasm (WebAssembly) support via Scala.js, refer here.

Added by @Quafadas in #3255.

Features

  • Add a --js-emit-wasm option and a corresponding using directive by @Quafadas in #3255

Deprecations

  • Deprecate the --source command line option for the package sub-command by @Gedochao in #3257

Fixes

  • Fix --watch to work correctly with changing using directives & sources requiring code generation (scripts, markdown, etc) by @Gedochao in #3218
  • Ensure resource directories passed via a using directive aren't ignored in --watch mode by @Gedochao in #3221
  • Ensure consecutive -Wconf:* flags are not ignored by @Gedochao in #3245

Documentation changes

  • Mention the Fix command in the Using directives guide by @dabrowski-adam in #3239
  • Back port of documentation changes to main by @github-actions in #3242

(⚡️ experimental) Support for exporting to a Maven project

It is now possible to export a Scala CLI project to Maven.

scala-cli export --script-snippet 'println("No need to create the pom.xml yourself!")' --mvn --power -o mvn-demo
# Some utilized features are marked as experimental:
#  - `export` sub-command
#  - `--mvn` option
# Please bear in mind that non-ideal user experience should be expected.
# If you encounter any bugs or have feedback to share, make sure to reach out to the maintenance team at https://github.com/VirtusLab/scala-cli
# Exporting to a maven project...
# Exported to: ~/scala-cli-tests/mvn-demo
cd mvn-demo
mvn scala:run -DmainClass=snippet_sc
# (...)
# No need to create the pom.xml yourself!
# [INFO] ------------------------------------------------------------------------
# [INFO] BUILD SUCCESS
# [INFO] ------------------------------------------------------------------------

# [INFO] Finished at: 2024-08-22T12:08:36+02:00
# [INFO] ------------------------------------------------------------------------

Added by @yadavan88 in #3003.

Support for launching apps from dependencies without other inputs

It is now possible to launch an app by just specifying its dependency, without the need to provide any source files.
In such a case the build server will not be started, as there's no compilation to be done.
There's also no need to specify the main class, as it's now being detected automatically in dependencies as well.
Do note that explicitly calling the run sub-command is necessary here, as otherwise Scala CLI will default to the REPL.

scala-cli run --dep io.get-coursier:coursier-cli_2.13:2.1.10 -- version
# 2.1.10

This can be used similarly to Coursier's cs launch.

Added by @kasiaMarek in #3079.

(⚡️ experimental) JMH available in various commands and via using directives

Some improvements have been done to the experimental support for JMH (Java Microbenchmark Harness).

The --jmh and --jmh-version options can now be passed to a number of commands:

  • run, as it was before (note that when --jmh is passed to run, the project's main class will default to running the benchmarks rather than the project's default main method; this behaviour is likely to be changed in future versions).
  • compile, so that a Scala CLI project with benchmarking can be compiled separately from being run;
  • package, although the resulting artifacts will run the project as normal for now, rather than benchmarks;
  • setup-ide, so that benchmarking projects can be imported to your IDE of choice;
  • test and export will now also no longer fail with --jmh, although no specific implementations for benchmarking are in place there yet.

It is now also possible to control JMH with using directives:

  • //> using jmh allows to enable JMH for the project, being the equivalent of the --jmh option.
  • //> using jmhVersion <version> allows to set the JMH version to use, being the equivalent of the --jmh-version option.
//> using jmh
//> using jmhVersion 1.37
package bench

import org.openjdk.jmh.annotations.*
import java.util.concurrent.TimeUnit

@BenchmarkMode(Array(Mode.AverageTime))
@OutputTimeUnit(TimeUnit.NANOSECONDS)
@Warmup(iterations = 1, time = 100, timeUnit = TimeUnit.MILLISECONDS)
@Measurement(iterations = 10, time = 100, timeUnit = TimeUnit.MILLISECONDS)
@Fork(0)
class Benchmarks {
  @Benchmark
  def foo(): Unit = {
    (1L to 1000L).sum
  }
}

Expect more improvements in this area in the future.
Also, do play with it and give us feedback about the current implementation!

Added by @Gedochao in #3091 and #3118.

Support for auto-completions in fish

We now have command line auto-completions for the fish shell.

Added by @KristianLentino99 in #3104.

--js-es-module-import-map no longer requires --power mode

A bit of a minor thing, but you can now use the --js-es-module-import-map option without enabling --power mode.

Added by @Gedochao in #3086.

Environment variable help with --env-help

You can now list environment variables used internally with the --envs-help flag.
This does include some environment variable used by Scala CLI's dependencies (like Coursier, Bloop, etc.), but should not be treated as an exhaustive list.

scala-cli --env-help --power

v1.4.1

Pass compiler args as an @argument file

You can shorten or simplify a Scala CLI command by using an @argument file to specify a text file that contains compiler arguments.

-d
outputDirectory

The feature may help to work around the Windows command line character limit, among other things, making sure your scripts run on any operating system of your choice.

scala-cli run -e 'println("Hey, I am using an @args file!")' @args.txt

This works similarly to the command-line argument files feature of Java 9 and fixes backwards compatibility with the old scala runner (pre-Scala-3.5.0).

Added by @kasiaMarek in #3012

Explicitly enable or disable multithreading in Scala Native

It is now possible to explicitly enable or disable multithreading in Scala Native builds.
You can do it by setting the //> using nativeMultithreading directive:

//> using platform native
//> using nativeMultithreading
import scala.concurrent._
import scala.concurrent.duration._
import ExecutionContext.Implicits.global
val promise = Promise[Int]()
val thread = new Thread(new Runnable {
    def run(): Unit = {
      Thread.sleep(100)
      promise.success(42)
    }
  })
thread.start()
val result = Await.result(promise.future, 2.seconds)
println(result)

Or the --native-multithreading command line option:

scala-cli run native_multithreading.sc --native --native-multithreading

Added by @Gedochao in #3011.

Features

  • Add a command line option & directive for enabling/disabling Scala Native multithreading by @Gedochao in #3011
  • feat: allow to pass scalac options using files by @kasiaMarek in #3012

Running the REPL with the test scope included

It is now possible to start the Scala REPL with access to the test scope.
To do so, it's enough to pass the --test flag with the repl sub-command.

package example
object ReplTestScopeExample {
  def message: String = "calling test scope from repl"
}
scala-cli repl ReplTestScopeExample.test.scala --test
# Compiling project (test, Scala 3.4.2, JVM (17))

The using jvm directives are now always respected

Formerly, if the build server (Bloop) was running on an older JVM than the one specified in a using jvm directive, the directive wouldn't be respected. We now restart the build server based on both the directive and the respective command line option (--jvm).

//> using jvm 22
//> using javacOpt --enable-preview -Xlint:preview
//> using javaOpt --enable-preview
//> using mainClass Simple

void main() {
    System.out.println("Hello from Java 22");
}

Support for Scala Native 0.5.4

This Scala CLI version adds support for Scala Native 0.5.4.
Native platform builds will now use 0.5.4 as the default version.

Scala Toolkit 0.4.0 & 0.3.0 defaults

This Scala CLI version treats Scala Toolkit 0.4.0 as the default version under most circumstances.

//> using toolkit default
@main def main() = println(os.pwd)

This unlocks the Scala Toolkit to be used with Scala Native 0.5.x.

scala-cli -e 'println(os.pwd)' --toolkit default --native   
# Compiling project (Scala 3.4.2, Scala Native 0.5.4)
# Compiled project (Scala 3.4.2, Scala Native 0.5.4)

# [info] Multithreading was not explicitly enabled - initial class loading has not detected any usage of system threads. Multithreading support will be disabled to improve performance.
# [info] Linking (multithreadingEnabled=false) (543 ms)
# [info] Discovered 880 classes and 5417 methods after classloading
# [info] Checking intermediate code (quick) (15 ms)
# [info] Discovered 857 classes and 4238 methods after optimization

# [info] Linking native code (immix gc, none lto) (81 ms)
# [info] Postprocessing (0 ms)
# [info] Total (4542 ms)

Scala Native 0.4.x has been dropped in Scala Toolkit 0.4.0 and above, so the last version supporting it, 0.3.0 (and lower), will now make the build default to Scala Native 0.4.17.

scala-cli -e 'println(os.pwd)' --toolkit 0.3.0 --native                          
# [warn] Scala Toolkit Version(0.3.0) does not support Scala Native 0.5.3, 0.4.17 should be used instead.
# [warn] Scala Native default version 0.5.3 is not supported in this build. Using 0.4.17 instead.
# Compiling project (Scala 3.4.2, Scala Native 0.4.17)
# Compiled project (Scala 3.4.2, Scala Native 0.4.17)
# [info] Linking (900 ms)
# [info] Checking intermediate code (quick) (63 ms)

# [info] Total (4406 ms)
# ~/scala-cli-tests

The troublesome case is when Scala Native 0.4.x is passed explicitly, while the Scala Toolkit is set to the default.
Scala CLI does not currently support downgrading the Scala Toolkit in this case, and fails the build.
