org.jline.terminal.impl.Diag

public class Diag
extends Object

Diagnostic utility for JLine terminals.

The Diag class provides diagnostic tools for analyzing and troubleshooting JLine terminal configurations. It can be used to gather information about the current environment, available terminal providers, system properties, and other details relevant to terminal operation.

This class can be run as a standalone application to generate a diagnostic report, which is useful for debugging terminal-related issues. The report includes information such as:

• Java version and system properties
• Operating system details
• Available terminal providers
• Terminal capabilities and attributes
• Console and TTY information

The diagnostic information can help identify configuration issues, missing dependencies, or platform-specific problems that might affect terminal functionality.
