Joe Bot - Redis Memory

Integrating Joe with Redis. https://github.com/go-joe/joe

This repository contains a module for the Joe Bot library.

THIS SOFTWARE IS STILL IN ALPHA AND THERE ARE NO GUARANTEES REGARDING API STABILITY YET.

Getting Started

This library is packaged using the new Go modules. You can get it via:

go get github.com/go-joe/redis-memory

Example usage

In order to connect your bot to Redis you can simply pass it as module when creating a new bot:

package main

import (
	"github.com/go-joe/joe"
	"github.com/go-joe/redis-memory"
	"github.com/pkg/errors"
)

type ExampleBot struct {
	*joe.Bot
}

func main() {
	b := &ExampleBot{
		Bot: joe.New("example",
			redis.Memory("localhost:6379"),
		),
	}

	b.Respond("remember (.+) is (.+)", b.Remember)
	b.Respond("what is (.+)", b.WhatIs)
	b.Respond("show keys", b.ShowKeys)

	err := b.Run()
	if err != nil {
		b.Logger.Fatal(err.Error())
	}
}

func (b *ExampleBot) Remember(msg joe.Message) error {
	key, value := msg.Matches[0], msg.Matches[1]
	msg.Respond("OK, I'll remember %s is %s", key, value)
	return b.Store.Set(key, value)
}

func (b *ExampleBot) WhatIs(msg joe.Message) error {
	key := msg.Matches[0]
	var value string
	ok, err := b.Store.Get(key, &value)
	if err != nil {
		return errors.Wrapf(err, "failed to retrieve key %q from brain", key)
	}

	if ok {
		msg.Respond("%s is %s", key, value)
	} else {
		msg.Respond("I do not remember %q", key)
	}

	return nil
}

func (b *ExampleBot) ShowKeys(msg joe.Message) error {
	keys, err := b.Store.Keys()
	if err != nil {
		return err
	}

	msg.Respond("I got %d keys:", len(keys))
	for i, k := range keys {
		msg.Respond("%d) %q", i+1, k)
	}
	return nil
}
