Class Main

java.lang.Object
ch.turic.cli.Main
public class Main extends Object
The Main class serves as the entry point of the application. It processes command-line arguments, configures program settings, and executes the specified actions, such as displaying version information, starting a REPL environment, or compiling and running the program files.

The application supports the following command-line options: - -version: Displays the current application version and build time. - -help: Prints the usage information and available options. - -APPIA=<import path>: Specifies import directories. - -compile: Compiles the input program file to a `.turc` format. - -REPL: Launches the REPL (Read-Eval-Print Loop) environment.

It expects a file with one of the following extensions for program execution: - .turi: The source code to be compiled and executed. - .turc: A pre-compiled bytecode file to be executed.

Behavior: - If no valid program file is provided, an IllegalArgumentException is thrown. - If the file has an unrecognized extension, an error message is displayed. - Compilation is optional and can be triggered with the -compile flag.

Handles unhandled exceptions by printing the stack trace to the standard error stream and exiting with a non-zero status.
