echotron

Library for telegram bots written in pure go

Fetch with

go get -u github.com/NicoNex/echotron

Usage

A very simple implementation:

package main

import "github.com/NicoNex/echotron"

type bot struct {
    chatId int64
    echotron.Api
}

func newBot(api echotron.Api, chatId int64) echotron.Bot {
    return &bot{
        chatId,
        api,
    }
}

func (b *bot) Update(update *echotron.Update) {
    if update.Message.Text == "/start" {
        b.SendMessage("Hello world", b.chatId)
    }
}

func main() {
    dsp := echotron.NewDispatcher("TELEGRAM TOKEN", newBot)
    dsp.Run()
}

Also proof of concept with self destruction for low ram usage

package main

import "github.com/NicoNex/echotron"

type bot struct {
    chatId int64
    echotron.Api
}

var dsp echotron.Dispatcher

func newBot(api echotron.Api, chatId int64) echotron.Bot {
    var bot = &bot{
        chatId,
        api,
    }
    echotron.AddTimer(bot.chatId, "selfDestruct", bot.selfDestruct, 60)
    return bot
}

func (b *bot) selfDestruct() {
    b.SendMessage("goodbye", b.chatId)
    echotron.DelTimer(b.chatId, "selfDestruct")
    dsp.DelSession(b.chatId)
}

func (b *bot) Update(update *echotron.Update) {
    if update.Message.Text == "/start" {
        b.SendMessage("Hello world", b.chatId)
    }
}

func main() {
    dsp = echotron.NewDispatcher("TELEGRAM TOKEN", newBot)
    dsp.Run()
}
