v0.1.16

This release consists mainly of updates, fixes, and various enhancements of existing features.

Enhancements

Specifying javac options via using directives

javac options can now be added via using directives, like

//> using javacOpt "source", "1.8", "target", "1.8"

Added by @lwronski in #1438

Pressing enter in watch mode proceeds to run / compile / test / … again

In watch mode (using the -w or --watch option), pressing Enter when Scala CLI is watching for changes makes it run again what it's supposed to be doing (compiling, running, running tests, or packaging, etc.) This is inspired by Mill's behaviour in watch mode, which supports the same feature.

Installation via Scoop on Windows

Scala CLI can now be installed via Scoop on Windows, with a command such as

scoop install scala-cli

Added by @nightscape in #1416, thanks to him!

Actionable diagnostics in Metals

Scala CLI should now send text edit suggestions with some of its diagnostics, via BSP, so that editors
can suggest those edits to users. This should work in upcoming versions of Metals in particular.

Added by @lwronski in #1448

Fixes

Fixes in Scala Native binaries caching

When running a sequence of commands such as

$ scala-cli run --native .
$ scala-cli package --native . -o my-app

Scala CLI should cache a Scala Native binary during the first command, so that the second command can just re-use it, rather than generating a binary again. This also fixes the re-use of compilation artifacts between both commands, so that the Scala CLI project isn't re-compiled during the second command either.

Fixed by @alexarchambault in #1406

Accept more scalac options without escaping

Scala CLI now accepts options such as -release, -encoding, -color, -feature, -deprecation and -nowarn, without requiring them to be escaped by -O. It also accepts --scalac-verbose, which is equivalent to -O -verbose (increases scalac verbosity). Lastly, it warns when -release and / or -target:<target> are inconsistent with --jvm.

Fixed by @Gedochao in #1413

Fix --java-option and --javac-option handling in package sub-command

--java-option and --javac-option should now be accepted and handled properly in the package sub-command.

Fixed by @lwronski in #1434

Fix wrong file name when publising Scala.js artifacts locally

The publish local sub-command used to publish Scala.js artifacts with a malformed suffix. This is now fixed.

Fixed by @lwronski in #1443

Fix spurious stack traces in the publish and publish local sub-commands

The publish and publish local commands could print spurious stack traces when run with non-default locales, using native Scala CLI binaries. This is now fixed.

Fixed by @romanowski in #1423

Make run --python --native work from Python virtualenv

Using both --native and --python in the run sub-command should work fine from Python virtualenv.

Fixed by @kiendang in #1399, thanks to him!
