Library — Arcjav-s

To provide an easy way to access the informative feature, we can create a command-line interface (CLI) using the picocli library:

// InfoCommand.java
package com.arcjav.info;
import picocli.CommandLine;
import picocli.CommandLine.Command;
@Command(name = "arcjav-info", mixinStandardHelpOptions = true, version = "1.0",
           description = "ARCJAV-s library informative feature")
public class InfoCommand implements Runnable 
    @Override
    public void run() 
        // Display overview
        System.out.println("ARCJAV-s library informative feature");
// Display usage examples
        UsageExamples usageExamples = new UsageExamples();
        usageExamples.main(null);
// Display configuration options
        ConfigOptions configOptions = new ConfigOptions();
        System.out.println("Configuration options:");
        // Display options
// Display changelog and version information
        Changelog changelog = new Changelog();
        System.out.println("Changelog:");
        System.out.println(changelog.getChangelog());
public static void main(String[] args) 
        int exitCode = new CommandLine(new InfoCommand()).execute(args);
        System.exit(exitCode);

To include a changelog and version information, we can create a Changelog class that reads from a Markdown file: ARCJAV-s Library

// Changelog.java
package com.arcjav.info;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class Changelog 
    public static String getChangelog() 
        File file = new File("changelog.md");
        Scanner scanner = new Scanner(file);
        StringBuilder changelog = new StringBuilder();
        while (scanner.hasNextLine()) 
            changelog.append(scanner.nextLine()).append("\n");
scanner.close();
        return changelog.toString();

To provide usage examples, we can create a UsageExamples class that contains code snippets and explanations: To provide an easy way to access the

// UsageExamples.java
package com.arcjav.info;
public class UsageExamples 
    public static void main(String[] args) 
        // Example 1: Basic usage
        System.out.println("Basic usage example:");
        // Code snippet
// Example 2: Advanced usage
        System.out.println("Advanced usage example:");
        // Code snippet
