Nyxx commands

Nyxx commands is a framework for easily creating slash commands and text commands for Discord using the nyxx library.

Insipred by discord.py's commands extension.

Features

• Easy command creation
• Automatic compatibility with Discord slash commands
• Compatibility with the nyxx library
• Argument parsing

Quick start

Create a bot:

Bot bot = Bot(
  '<token>',
  GatewayIntents.allUnprivileged,
  prefix: '!',
  guild: Snowflake('<guild id>'), // Omit if you want commands to be registered globally
);

Create and register a simple command:

Command command = Command(
  'hi', // Command name
  'A simple command', // Command description
  (Context context, String name) async { // Command syntax and callback
    await context.respond(MessageBuilder.content('Hello, $name!'));
  },
);

bot.registerChild(command);

Use a custom type converter:

Command command = Command(
  'pet',
  'A command with a type converter',
  (Context context, bool hasCat  /* User input will automatically be converted */) async {
    if (hasCat) {
        await context.respond(MessageBuilder.content('I have a cat.'));
    } else {
        await context.respond(MessageBuilder.content('I do not have any pets.'));
    }
  },
);

Use an optional argument:

Command command = Command(
  'sayhi',
  'A command with an optional argument',
  (Context context, String name, [String? familyName /* This parameter is optional. Notice that optional parameters are *not* named parameters! */]) async {
      await context.respond(MessageBuilder.content('My name is $name ${familyName ?? ""}'));
  },
);

// Also notice how the name "familyName" was converted to "family-name" in the registered slash command,
// this is to ensure discord accepts the parameter name.

Use a command group:

Group group = Group(
  'say',
  'An example group',
  children: [
    Command(
      'hi',
      'Say hi',
      (Context context) async {
        await context.respond(MessageBuilder.content('Hi!'));
      },
    ),
    Command(
      'goodbye',
      'Say goodbye',
      (Context context) async {
        await context.respond(MessageBuilder.content('Goodbye :('));
      },
    )
  ],
);

// Register the group to the bot
bot.registerChild(group);
