tgbot-cpp

C++ library for Telegram bot API.

NOTE: Library is under massive reconstruction. Expect backwards-incompatible changes!

API support

• Bot API 2.3.1
• Bot API 3.0 (everything except payments)
• Bot API 3.1
• Bot API 3.2
• Bot API 3.3
• Bot API 3.4

Requirements

• CMake 3.2+
• Boost 1.59+ system compomnent for library; regex, iostreams, unit_test_framework for tests.
• OpenSSL

Following should be enough on Debian-based distros:

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

Compilaton

git clone https://github.com/foxcpp/tgbot-cpp
cd tgbot-cpp
mkdir build; cd build
cmake ..
make

Bot compilation

System library

find_package(tgbot-cpp REQUIRED)

add_executable(bot-exe-name file.cpp)
target_link_libraries(bot-exe-name tgbot)

Submodule

add_subdirectory(tgbot-cpp/) # Make sure it points to directory where you placed tgbot-cpp

add_executable(bot-exe-name files.cpp)
target_link_libraries(bot-exe-name tgbot)

Examples

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;
}
