Using component interactions (select menus)

This example demonstrates receiving select menu clicks and sending response messages.

#include <dpp/dpp.h>
 
using json = nlohmann::json;
 
int main()
{
 
    dpp::cluster bot("token");
 
    /* Message handler to look for a command called !select */
    bot.on_message_create([&bot](const dpp::message_create_t & event) {
        if (event.msg.content == "!select") {
            /* Create a message containing an action row, and a select menu within the action row. */
            dpp::message m(event.msg.channel_id, "this text has a select menu");
            m.add_component(
                dpp::component().add_component(
                    dpp::component().set_type(dpp::cot_selectmenu).
                    set_placeholder("Pick something").
                    add_select_option(dpp::select_option("label1","value1","description1").set_emoji(u8"😄")).
                    add_select_option(dpp::select_option("label2","value2","description2").set_emoji(u8"🙂")).
                    set_id("myselid")
                )
            );
            bot.message_create(m);
        }
    });
    /* When a user clicks your select menu , the on_select_click event will fire,
     * containing the custom_id you defined in your select menu.
     */
    bot.on_select_click([&bot](const dpp::select_click_t & event) {
        /* Select clicks are still interactions, and must be replied to in some form to
         * prevent the "this interaction has failed" message from Discord to the user.
         */
        event.reply(dpp::ir_channel_message_with_source, "You clicked " + event.custom_id + " and chose: " + event.values[0]);
    });
 
    bot.on_log([](const dpp::log_t & event) {
        if (event.severity > dpp::ll_trace) {
            std::cout << event.message << "\n";
        }
    });
 
    bot.start(false);
 
    return 0;
}
