commands

commands

dead simple command handler & registerer.

getting started

package main

import (
	"codeberg.org/Yonle/irc/commands"
)

var cmds commands.Commands = make(commands.Commands)

in another code file:

package main

import (
	"codeberg.org/Yonle/irc"
	"codeberg.org/Yonle/irc/commands"
)

// assuming this code is for "ping" command

func init() {
	cmds.RegisterCommand("ping", func (conn io.Writer, user irc.User, to, _ string) {
		irc.Chat(conn, to, user.Nick + ": Pong!")
	})
}

then, let the helper listen to messages in your scanner:

var cmds commands.Commands
for s.Scan() {
	// ...
	user, cmd, flags, fullmsg := irc.ParseLine(line)
	if cmd == "PRIVMSG" {
		msg, hasPrefix := strings.CutPrefix(fullmsg, "!") // assuming ! is your bot's prefix
		if !hasPrefix {
			continue // ignore message that has no bot prefix
		}

		to := flags[0]

		if to == botnick {
			to = user.Nick // this is PM
		}

		invalid := cmds.ReadMessage(conn, user, to, msg)
		if invalid {
			irc.Chat(conn, to, fmt.Sprintf("%s: Unknown command", user.Nick))
		}
	}
}

finally, boot up your bot, and send !ping. it should replies.

<Anon> !ping
<ircbot> Anon: Pong!
