Arguments

Commands can accept arguments. Just define a class field and slap the @arg decorator on top:

@command("reverse")
export class ReverseCommand extends SlashCommand {
  @arg()
  text: string;

  async execute() {
    const reversed = this.text.split("").reverse().join("");
    await this.reply(reversed);
  }
}

For example, if a user types "/reverse hello", the text field will be set to "hello".
