Is there something like an AbilityExtension, but for Replies?

[MRiabov]

Hey, it's obvious for me that it's a bad idea to have all the replies and replyFlows in one "extends AbilityBot" class. I didn't find anything like that in the manual. Perhaps there is something that can hide all those loads of replies?

Thanks in advance!

You're right—keeping all replies and replyFlows within a single AbilityBot class can quickly become unwieldy and hard to manage. To improve the structure of your bot and make it more maintainable, you can use several strategies to organize and modularize your code. Here’s how you can achieve that:

1. Separate Abilities into Different Classes

Instead of putting all abilities into one AbilityBot class, create separate classes for different functionalities or commands. Each class can then focus on a specific aspect of your bot.

Example:

public class MyBot extends AbilityBot {

    public MyBot(String botToken, String botUsername) {
        super(botToken, botUsername);
    }

    @Override
    public int creatorId() {
        return YOUR_CREATOR_ID;
    }

    // Methods to handle general bot setup
}

Abilities:

public class GreetingAbility {

    public Ability greet() {
        return Ability.builder()
            .name("greet")
            .info("Sends a greeting message")
            .locality(Ability.Locality.CHAT)
            .privacy(Ability.Privacy.PUBLIC)
            .action(ctx -> ctx.reply("Hello! How can I help you today?"))
            .build();
    }
}

public class InlineQueryAbility {

    public Ability handleInlineQuery() {
        return Ability.builder()
            .name("inlineQuery")
            .info("Handles inline queries")
            .locality(Ability.Locality.GROUP)
            .privacy(Ability.Privacy.PUBLIC)
            .action(ctx -> {
                // Inline query handling logic
            })
            .build();
    }
}

Using Abilities:

public class BotApplication {

    public static void main(String[] args) {
        MyBot bot = new MyBot("YOUR_BOT_TOKEN", "YOUR_BOT_USERNAME");

        bot.addAbility(new GreetingAbility().greet());
        bot.addAbility(new InlineQueryAbility().handleInlineQuery());

        bot.start();
    }
}

2. Use Dependency Injection

To manage dependencies and keep your code clean, consider using a dependency injection framework like Spring. This way, you can inject different components (e.g., services or handlers) into your bot class, keeping your code modular and easier to test.

Example with Spring:

import org.springframework.stereotype.Component;

@Component
public class GreetingService {

    public String getGreeting() {
        return "Hello! How can I help you today?";
    }
}

@Component
public class MyBot extends AbilityBot {

    private final GreetingService greetingService;

    public MyBot(String botToken, String botUsername, GreetingService greetingService) {
        super(botToken, botUsername);
        this.greetingService = greetingService;
    }

    @Override
    public int creatorId() {
        return YOUR_CREATOR_ID;
    }

    public void initialize() {
        this.addAbility(Ability.builder()
            .name("greet")
            .info("Sends a greeting message")
            .locality(Ability.Locality.CHAT)
            .privacy(Ability.Privacy.PUBLIC)
            .action(ctx -> ctx.reply(greetingService.getGreeting()))
            .build());
    }
}

3. Organize Replies and Handlers in Separate Files

Create separate files or classes for replies and handlers. This way, you can organize different functionalities or commands in their own files, making the codebase easier to navigate.

Example:

GreetingHandler.java:

public class GreetingHandler {

    public void handleGreeting(Update update) {
        // Implementation for handling greeting messages
    }
}

InlineQueryHandler.java:

public class InlineQueryHandler {

    public void handleInlineQuery(InlineQuery inlineQuery) {
        // Implementation for handling inline queries
    }
}

In your main bot class:

public class MyBot extends AbilityBot {

    private final GreetingHandler greetingHandler;
    private final InlineQueryHandler inlineQueryHandler;

    public MyBot(String botToken, String botUsername, GreetingHandler greetingHandler, InlineQueryHandler inlineQueryHandler) {
        super(botToken, botUsername);
        this.greetingHandler = greetingHandler;
        this.inlineQueryHandler = inlineQueryHandler;
    }

    @Override
    public int creatorId() {
        return YOUR_CREATOR_ID;
    }

    @Override
    public void onUpdateReceived(Update update) {
        if (update.hasMessage()) {
            greetingHandler.handleGreeting(update);
        } else if (update.hasInlineQuery()) {
            inlineQueryHandler.handleInlineQuery(update.getInlineQuery());
        }
        // Handle other update types
    }
}

4. Modularize with Packages

Group related classes into packages to keep your project organized. For instance, you could have packages like handlers, services, models, etc.

Example Structure:

src
|-- main
    |-- java
        |-- com
            |-- yourcompany
                |-- bot
                    |-- MyBot.java
                    |-- commands
                        |-- GreetingCommand.java
                        |-- InlineQueryCommand.java
                    |-- handlers
                        |-- GreetingHandler.java
                        |-- InlineQueryHandler.java
                    |-- services
                        |-- GreetingService.java
