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 .

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)
