Commands adding:

For example let's implement ping command.

• Create new branch and checkout
• Go to commands package
• Create new ping package inside
• Create class PingCommand

  @Component
  class PingCommand(val messageBuilder: PingMessage) : Command {
    override val caller: String = "ping" //NOTE! val caller is representing how will you call command (e.g. !ping)
    override val description: String = "Ping command description"
    override lateinit var event: GuildMessageReceivedEvent
    
    /*
      args - are everything you pass after your command
      e.g. !ping kek lol
      where 
        args[0] == kek
        args[1] == lol
    */
    override fun invoke(args: List<String>) {
      // Calculating latency.
      messageBuilder.latency(latency).send(event)
    }
  }

• Create object PingMessage

  @Component
  final object PingMessage : MessageBuilder() {
  
     /*
       Use your property you want to pass to message.
     */
    private var latency = 0L
    fun latency(latency: Long) = apply { this.latency = latency }
  
    override fun send(event: GuildMessageReceivedEvent) {
      event.channel.sendMessage(createMessage()).queue()
    }
  
     /*
       Inside this method you can customize your message.
       Example below.
     */
    override fun createMessage(): MessageEmbed {
      return super
        .setTitle("$latency ms")
        .setDescription("Pong-pong")
        .setColor(GREEN)
        .build()
    }
  }
