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

"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.
