Advanced Command Creation

Overview

Advanced commands combine option schemas, context-menu types, categories, validation, permissions, cooldowns, and middleware. The router keeps these policies close to the command definition.

Quick Start

package main
import (
    "errors"
    "time"
    "github.com/discord-go/discord.go/bot"
    "github.com/discord-go/discord.go/interactions"
    "github.com/discord-go/discord.go/permissions"
)
func register(r *bot.Router) {
    r.Command("lookup", "Look up a user", func(c *bot.InteractionContext) { _ = c.Reply(c.GetUserID("user").String()) }, interactions.ApplicationCommandOption{Type: interactions.ApplicationCommandOptionTypeUser, Name: "user", Description: "Target", Required: true}).RequirePermissions(permissions.ManageGuild).Cooldown(time.Second).Use(bot.Validate(func(c *bot.InteractionContext) error { if !c.InGuild() { return errors.New("guild only") }; return nil }))
}

Common Patterns

Use ContextCommand, UserCommand, and MessageCommand for context menus. Use InCategory for help systems and RangeCommands to build deterministic command indexes.

Common Mistakes

Do not hide required options in handler code. Put requiredness and descriptions in ApplicationCommandOption so Discord validates input before invocation.
