tgbot-cpp

C++ library for Telegram bot API.

Documentation is located here.

Library compilation

Firstly you need to install some dependencies such as Boost and build tools such as CMake. On Debian-based distibutives you can do it with these commands:

sudo apt-get install g++ make binutils cmake libssl-dev libboost-system-dev libboost-iostreams-dev

To compile the library execute this commands:

cd /path/where/you/have/cloned/the/library/repository
cmake .
make -j4
sudo make install

Bot compilation

With CMake

Example CMakeLists.txt

Without CMake

g++ telegram_bot.cpp -o telegram_bot --std=c++11 -I/usr/local/include -lTgBot -lboost_system -lboost_iostreams -lssl -lcrypto -lpthread

You can use Docker to build and run your bot. Set the base image of your's Dockerfile to reo7sp/tgbot-cpp.

Samples

Simple echo bot which sends everything it receives:

#include <stdio.h>
#include <tgbot/tgbot.h>

int main() {
    TgBot::Bot bot("PLACE YOUR TOKEN HERE");
    bot.getEvents().onCommand("start", [&bot](TgBot::Message::Ptr message) {
        bot.getApi().sendMessage(message->chat->id, "Hi!");
    });
    bot.getEvents().onAnyMessage([&bot](TgBot::Message::Ptr message) {
        printf("User wrote %s\n", message->text.c_str());
        if (StringTools::startsWith(message->text, "/start")) {
            return;
        }
        bot.getApi().sendMessage(message->chat->id, "Your message is: " + message->text);
    });
    try {
        printf("Bot username: %s\n", bot.getApi().getMe()->username.c_str());
        TgBot::TgLongPoll longPoll(bot);
        while (true) {
            printf("Long poll started\n");
            longPoll.start();
        }
    } catch (TgBot::TgException& e) {
        printf("error: %s\n", e.what());
    }
    return 0;
}
