README

What is content branch

This fork is simple and very helpful if you develop big and complex projects. The main goal is to manage bot's content easily – texts, buttons, keyboards etc. Also this package contains some patches and fixes by me that is still not accepted in original tucnak/telebot repository.

Feel free to use, contribute and ask questions!

Examples

@EmojiTextBot
  • YAML configuration
  • Common project structure
@FindYoutubeBot
  • JSON configuration
  • Simple project structure

How to use

package main

import tb "github.com/demget/telebot"

func main() {

	tmpl := &tb.TemplateText{
		// your message templates directory
		Dir: "data",

		// custom functions that you can use later in your template
		// example: `${ upper "some string" }` = `SOME STRING`
		Funcs: template.FuncMap{
			"upper": strings.ToUpper,
		},

		// custom delimiters for valid YAML parsing
		DelimLeft:  "${",
		DelimRight: "}",
	}

	// "bot.json" is your config file
	// "tmpl" is your template engine
	pref, err := tb.NewSettings("bot.json", tmpl)
	// if you chose yaml as a config language:
	pref, err := tb.NewSettingsYAML("bot.yml", tmpl)
	if err != nil {
		log.Fatalln(err)
	}

	// you also can store token in config
	pref.Token = os.Getenv("TOKEN") 
	pref.Reporter = report

	b, err := tb.NewBot(pref)
	if err != nil {
		log.Fatalln(err)
	}

	b.Handle("/start", handler.OnStart)
	b.Handle("/item", handler.OnItem)
	b.Handle(b.InlineButton("refresh"), handler.OnRefresh)
	b.Handle(b.InlineButton("remove"), handler.OnRemove)

	b.Start()
}

Texts

Put all messages' texts in another folder, e.g. data. Each message is *.tmpl file that will be parsed and executed by text/template engine or by aymerick/raymond. You can select between them:

  • tb.TemplateText implements the text/template library
  • tb.TemplateHandlebars implements the aymerick/raymond library
Example
func OnStart(m *tb.Message) {
	b.Send(m.Sender, b.Text("hello", m.Sender), tb.ModeMarkdown)
}

Hi, *{{.FirstName}}*! → Hi, Pavel!

Hi, {{if .Username}}@{{.Username}}{{else}}*{{.FirstName}}*{{end}}! → Hi, @durov!

Vars

{
	"vars": {
		"secret": "qz_BuGo2",
		"admins": [],
		"limits": {
			"max_requests_per_user": 20
		}
	}
}

vars:
  secret: qz_BuGo2
  admins:
    - 1654231
    - 2465232
  limits:
    max_requests_per_user: 20

package app

type Config struct {
	Secret string `json:"secret"`
	Admins []int  `json:"admins"`
	Limits struct {
		MaxRequestsPerUser int `json:"max_requests_per_user"`
	}
}

var conf app.Config
if err := b.Vars(&conf); err != nil {
	log.Fatalln(err)
}

// now you can use your variables:
	conf.Secret
	conf.Admins
	conf.Limits

Reply keyboards

{
	"buttons": {
		"help": "❓ Help",
		"settings": "⚙️ Settings"
	},
	"keyboards": {
		"menu": [["help", "settings"]]
	}
}

buttons:
  help: "❓ Help"
  settings: "⚙️ Settings"
keyboards:
  menu:
  - - help
    - settings

func OnStart(m *tb.Message) {
	b.Send(m.Sender, 
		b.Text("hello", m.Sender), 
		b.Markup("menu"),
		tb.ModeMarkdown)
}

Inline keyboards + Strings

{
	"strings": {
		"removed": "Removed successfully!"
	},
	"inline_buttons": {
		"refresh": {
			"unique": "refresh",
			"callback_data": "{{.ID}}",
			"text": "🔄 Refresh"
		},
		"remove": {
			"unique": "remove",
			"callback_data": "{{.ID}}",
			"text": "🛑 Remove"
		}
	},
	"inline_keyboards": {
		"item": [["refresh"], ["remove"]]
	}
}

strings:
  removed: "Removed successfully!"

inline_buttons:
  refresh:
    unique: refresh
    callback_data: ${.ID}
    text: "🔄 Refresh"
  remove:
    unique: remove
    callback_data: ${.ID}
    text: "🛑 Remove"

inline_keyboards:
  item:
  - - refresh
    - remove

package handler

func OnItem(m *tb.Message) {
	b.Send(m.Sender, 
		b.Text("item", item), 
		b.InlineMarkup("item", item),
		tb.ModeMarkdown)
}

func OnRefresh(c *tb.Callback) {
	defer b.Respond(c)
	/* refresh */
}

func OnRemove(c *tb.Callback) {
	/* remove */

	b.Respond(c, &tb.CallbackResponse{
		Text:      b.String("removed"),
		ShowAlert: true,
	})
}

And very simple handling:

b.Handle("/item", handler.OnItem)
b.Handle(b.InlineButton("refresh"), handler.OnRefresh)
b.Handle(b.InlineButton("remove"), handler.OnRemove)

Inline query results

{
	"inline_results": {
		"item": {
			"type": "article",
			"id": "{{.ID}}",
			"title": "{{jsq .Title}}",
			"description": "{{jsq .Description}}",
			"thumb_url": "{{.ThumbnailURL}}"
		}
	}
}

inline_results:
  item:
    type: article
    id: ${.ID}
    title: ${jsq .Title}
    description: ${jsq .Description}
    thumb_url: ${.ThumbnailURL}

package handler

func OnQuery(q *tb.OnQuery) {
	var results tb.Results
	for _, item := range items {
		result := b.InlineResult("item", item)
		if result == nil { // something went wrong
			continue
		}

		result.SetContent(&tb.InputTextMessageContent{
			Text:      b.Text("item", item),
			ParseMode: tb.ModeHTML,
		})

		result.SetReplyMarkup(b.InlineMarkup("item", item))
		results = append(results, result)
	}

	b.Answer(q, &tb.QueryResponse{
		Results:   results,
		CacheTime: 300,
	})
}

Additional and custom template functions

There are some additional template functions which are accessible in any text template and config. Some simple things, that standard template package still not do. Check template.go for all pre-defined functions. The list will be extended in the future.

Examples:

{{add .N 4}} → 9

{{sub .N 4}} → 1

{{jsq `Some \weird json-incompatible "title"`}} → Some \\weird json-incompatible \"title\"

Documentation

Overview

Package telebot is a framework for Telegram bots.

Example: 

package main

import (
	"time"
	tb "gopkg.in/tucnak/telebot.v2"
)

func main() {
	b, err := tb.NewBot(tb.Settings{
		Token: "TOKEN_HERE",
		Poller: &tb.LongPoller{Timeout: 10 * time.Second},
	})

	if err != nil {
		return
	}

	b.Handle(tb.OnText, func(m *tb.Message) {
		b.Send(m.Sender, "hello world")
	})

	b.Start()
}

	ResultBase

	// A valid URL for the voice recording.
	URL string `json:"voice_url"`

	// Optional. Send Markdown or HTML, if you want Telegram apps to show
	// bold, italic, fixed-width text or inline URLs in the media caption.
	ParseMode ParseMode `json:"parse_mode,omitempty"`

	// If Cache != "", it'll be used instead

type Webhook 

type Webhook struct {
	Listen         string   `json:"url"`
	MaxConnections int      `json:"max_connections"`
	AllowedUpdates []string `json:"allowed_updates"`

	// (WebhookInfo)
	HasCustomCert  bool   `json:"has_custom_certificate"`
	PendingUpdates int    `json:"pending_update_count"`
	ErrorUnixtime  int64  `json:"last_error_date"`
	ErrorMessage   string `json:"last_error_message"`

	TLS      *WebhookTLS
	Endpoint *WebhookEndpoint
	// contains filtered or unexported fields
}

A Webhook configures the poller for webhooks. It opens a port on the given listen address. If TLS is filled, the listener will use the key and cert to open a secure port. Otherwise it will use plain HTTP.

If you have a loadbalancer ore other infrastructure in front of your service, you must fill the Endpoint structure so this poller will send this data to telegram. If you leave these values empty, your local address will be sent to telegram which is mostly not what you want (at least while developing). If you have a single instance of your bot you should consider to use the LongPoller instead of a WebHook.

You can also leave the Listen field empty. In this case it is up to the caller to add the Webhook to a http-mux.

func (*Webhook) Poll 

func (h *Webhook) Poll(b *Bot, dest chan Update, stop chan struct{})

func (*Webhook) ServeHTTP 

func (h *Webhook) ServeHTTP(w http.ResponseWriter, r *http.Request)

The handler simply reads the update from the body of the requests and writes them to the update channel.

type WebhookEndpoint 

type WebhookEndpoint struct {
	PublicURL string
	Cert      string
}

A WebhookEndpoint describes the endpoint to which telegram will send its requests. This must be a public URL and can be a loadbalancer or something similar. If the endpoint uses TLS and the certificate is self-signed you have to add the certificate path of this certificate so telegram will trust it. This field can be ignored if you have a trusted certificate (letsencrypt, ...).

type WebhookTLS 

type WebhookTLS struct {
	Key  string
	Cert string
}

A WebhookTLS specifies the path to a key and a cert so the poller can open a TLS listener
