New Modules and Exports!

For this release, we have added two enormous features to the language, modules and exports. Yes, these improvements will allow you to not only create modules containing public and private properties accessible from the outside of a module or within the same source code file.

Replace seq([exp1, exp2]) with { exp1; exp2 }
Blocks have their own scopes as well, and returns the value of the last expression in the sequence.

Installation

Windows

Download the rsc.zip or rsc-2.3.0.msi file and follow the instructions in README.md.

MacOS and Linux

Download the rsc.jar file and run as usual with java -jar rsc.jar

New

• Added Modules.
• Added Exports and Imports.
• Added Code Blocks, returning the value of the last expression.
• GlobalScope holding exported variables. This was made possible by thunneling the evaluated expression results using a new Atom.UnitBox back to PublicExpr which then could add the values to the export list if it is in the GlobalScope.
• Added support for relative paths when importing exported props from another file.
• Added REPL commands for moving around in the file system, and import from files.

New extensive CLI tool!

RustScript now comes pre-packaged inside the recently developed CLI tool rsc.
This is a command you can run to directly execute your script files, interact with the playful REPL or in upcoming releases, lint or even compile your scripts into other programming languages.

> java -jar rsc.jar
RustScript CLI version 0.1.0.
A simple command line interface tool for the RustScript language.

Usage: rsc (options) (files)

Options:
        -h, --help
                Prints this help message.
        -v, --version
                Prints the version of the program.
        -r, --repl
                Starts the REPL mode.
        -c, --compile [files]          (Not implemented)
                Compiles the given files.
        -l, --lint [files]             (Not implemented)
