wumpgoctl gen

wumpgoctl gen is a go:generate tool for generating wumpgo.dev/wumpgo/router commands from comments instead of writing the interface implementations yourself.

Usage

package main

import (
	"context"
	"flag"
	"fmt"
	"net/http"
	"strings"

	"wumpgo.dev/wumpgo/interactions"
	"wumpgo.dev/wumpgo/objects"
	"wumpgo.dev/wumpgo/rest"
	"wumpgo.dev/wumpgo/router"
)

// go:generate wumpgoctl gen

// Echo godoc
// @Description Echos the message you type back to you
type Echo struct {
	Message string `discord:"message,description:Message to echo back"`
}

// EchoCaps godoc
// @Description Echos the message you type back to you, but in all uppercase
// @Option.Message.Name.es_MX mensaje
type EchoCaps struct {
	Message string `discord:"message,description:Message to echo back"`
}

// Log godoc
// @Description Tests a channel argument
type Log struct {
	Channel *objects.Channel `discord:",channelTypes:0"`
}

// MyCommand godoc
// @Name testcommand
// @Description Test base command
// @Name.en_US testcommand
// @Name.es_MX commandodepreueba
// @Type ChatInput
type MyCommand struct {
	Echo
	EchoCaps
	Log
}
