Releases: VirtusLab/scala-cli
v1.5.4
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.

Full Changelog: v1.5.3...v1.5.4
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

v1.5.2
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 .
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
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

(⚡️ 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

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 torun
, 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
andexport
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.

Full Changelog: v1.4.1...v1.4.2
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)

v1.4.0
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))
# Compiled project (test, Scala 3.4.2, JVM (17))
# Welcome to Scala 3.4.2 (17, Java OpenJDK 64-Bit Server VM).
# Type in expressions for evaluation. Or try :help.
#
# scala> example.ReplTestScopeExample.message
# val res0: String = calling test scope from repl
#
# scala>
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-cli -e 'println("Hello, Scala Native!")' --native

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

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.

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.
scala-cli -e 'println(os.pwd)' --toolkit default --native --native-version 0.4.17
