go-tdlib

Golang Telegram TdLib JSON bindings

Introduction

Telegram Tdlib is a complete library for creating telegram clients, it laso has a simple tdjson ready-to-use library to ease the integration with different programming languages and platforms.

go-tdlib is a complete tdlib-tdjson binding package to help you create your own Telegram clients.

NOTE: basic tdjson-golang binding is inspired from this package: go-tdjson

All the classes and functions declared in Tdlib TypeLanguage schema file have been exported using the autogenerate tool tl-parser. So you can use every single type and method in Tdlib.

Key features:

Autogenerated golang structs and methods of tdlib .tl schema
Custom event receivers defined by user (e.g. get only text messages from a specific user)
Supports all tdjson functions: Send(), Execute(), Receive(), Destroy(), SetFilePath(), SetLogVerbosityLevel()
Supports all tdlib functions and types

Installation

First of all you need to clone the Tdlib repo and build it:

git clone git@github.com:tdlib/td.git
cd td
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build . -- -j5
make install

# -j5 refers to number of your cpu cores + 1 for multi-threaded build.

If hit any build errors, refer to Tdlib build instructions I'm using static linking against tdlib so it won't require to build the whole tdlib source files.

Docker

You can use prebuilt tdlib with following Docker image:

Windows:

docker pull mihaildemidoff/tdlib-go

Example

Here is a simple example for authorization and fetching updates:

package main

import (
	"fmt"

	"github.com/Arman92/go-tdlib"
)

func main() {
	tdlib.SetLogVerbosityLevel(1)
	tdlib.SetFilePath("./errors.txt")

	// Create new instance of client
	client := tdlib.NewClient(tdlib.Config{
		APIID:               "187786",
		APIHash:             "e782045df67ba48e441ccb105da8fc85",
		SystemLanguageCode:  "en",
		DeviceModel:         "Server",
		SystemVersion:       "1.0.0",
		ApplicationVersion:  "1.0.0",
		UseMessageDatabase:  true,
		UseFileDatabase:     true,
		UseChatInfoDatabase: true,
		UseTestDataCenter:   false,
		DatabaseDirectory:   "./tdlib-db",
		FileDirectory:       "./tdlib-files",
		IgnoreFileNames:     false,
	})

	for {
		currentState, _ := client.Authorize()
		if currentState.GetAuthorizationStateEnum() == tdlib.AuthorizationStateWaitPhoneNumberType {
			fmt.Print("Enter phone: ")
			var number string
			fmt.Scanln(&number)
			_, err := client.SendPhoneNumber(number)
			if err != nil {
				fmt.Printf("Error sending phone number: %v", err)
			}
		} else if currentState.GetAuthorizationStateEnum() == tdlib.AuthorizationStateWaitCodeType {
			fmt.Print("Enter code: ")
			var code string
			fmt.Scanln(&code)
			_, err := client.SendAuthCode(code)
			if err != nil {
				fmt.Printf("Error sending auth code : %v", err)
			}
		} else if currentState.GetAuthorizationStateEnum() == tdlib.AuthorizationStateWaitPasswordType {
			fmt.Print("Enter Password: ")
			var password string
			fmt.Scanln(&password)
			_, err := client.SendAuthPassword(password)
			if err != nil {
				fmt.Printf("Error sending auth password: %v", err)
			}
		} else if currentState.GetAuthorizationStateEnum() == tdlib.AuthorizationStateReadyType {
			fmt.Println("Authorization Ready! Let's rock")
			break
		}
	}

	// Main loop
	for update := range client.RawUpdates {
		// Show all updates
		fmt.Println(update.Data)
		fmt.Print("\n\n")
	}

}
