DiscordCoreAPI

Codacy Badge Discord Commit Activity Lines of Code

Hello, and welcome to DiscordCoreAPI! This is a Discord bot library, written in C++, that leverages custom asynchronous CoRoutines, as well as a home-brew set of Https, WebSocket, and Datagram socket clients - all to deliver the utmost performance and efficiency for your bot. It uses roughly 0.1% of an Intel i7 9750h CPU to stream audio in high quality (Opus @ 48Khz, 16-bit) to a single server.

Features

Convert Snowflakes Into Data

  • Using the discord_core_api::snowflake::toEntity() function of the snowflake class allows for converting the entity's id directly into the data structure represented by it.
discord_core_api::snowflake someChannelId{};
discord_core_api::channel_data newChannel = someChannelId.toEntity<discord_core_api::channel_data>();
std::cout << "CHANNEL NAME: " + newChannel.name << std::endl;

Performant

Audio-Bridge

  • Connect multiple voice-channels to one-another using the StreamInfo member of the VoiceConnectInitData structure, with the VoiceConnection class.

CPU Efficient

  • It only uses about 0.1% of an Intel i7 9750h to stream audio in high quality (Opus 48Khz 16-bit Stereo) to a single server.

Entire Discord API Covered

  • All of the Discord API endpoints are covered in this library, including voice communication.

Concurrent Discord API Access

Advanced Rate-Limiting System

  • Guarantees that the order in which HTTPS requests are executed is the same that they were submitted in - despite being launched across different threads, while never infracting on any of the Discord API's rate-limits and while running concurrently across all of the endpoints.

Slash Commands and Buttons

Select Menus

User Commands

Message Commands

Modal Text Inputs

A Unified "Input-Event" System

  • User interactions (Application Commands, Message Commands, User Commands) are accepted via the event_manager::onInputEventCreation event.
  • They can all be responded to using the input_events::respondToInputEventAsync() function.
  • Alternatively you can implement your own input-event handling by using the raw event_manager::onInteractionCreation or event_manager::onMessageCreation events.
EmbedData newEmbed{};
newEmbed.setAuthor(args.eventData.getUserName(), args.eventData.getAvatarURL());
newEmbed.setDescription("------\\n__**Sorry, but there's already something play
ing!**__\\n------");
newEmbed.setTimeStamp(getTimeAndDate());
newEmbed.setTitle("__**Playing Issue:**__");
newEmbed.setColor(discordGuild.data.borderColor);
RespondToInputEventData dataPackage{ args.eventData };
dataPackage.addMessageEmbed(newEmbed);
dataPackage.setResponseType(InputEventResponseType::Ephemeral_Interaction_Response);
InputEventData newEvent = input_events::respondToInputEvent(dataPackage);
input_events::deleteInputEventResponseAsync(newEvent, 20000).get();

Build Instructions (Full-Vcpkg)

  • Install vcpkg, if need be.
  • Make sure to run vcpkg integrate install.
  • Enter within a terminal vcpkg install discordcoreapi:x64-windows_OR_linux.
  • Set up a console project in your IDE and make sure to set the C++ standard to C++20 or later - and include discordcoreapi/Index.hpp.
  • Build and run!

Dependencies

  • CMake (Version 3.20 or greater)
  • NOTE: I installed these using the vcpkg installer.
  • DiscordCoreAPI (.\vcpkg install jsonifier:x64-windows_OR_linux)
  • OpenSSL (.\vcpkg install openssl:x64-windows_OR_linux)
  • Opus (.\vcpkg install opus:x64-windows_OR_linux)
  • Sodium (.\vcpkg install libsodium:x64-windows_OR_linux)

Build Instructions (Non-Vcpkg) - The Library

  • Install the dependencies.
  • Clone this git repository into a folder.
  • Set, in CMakeLists.txt, the _VCPKG_ROOT_DIR, or the Opus_DIR, unofficial-sodium_DIR paths to wherever each of the respective dependency files are located and they are as follows:
    • Opus_DIR # Set this one to the folder location of the file "OpusConfig.cmake".
    • unofficial-sodium_DIR # Set this one to the folder location of the file "unofficial-sodiumConfig.cmake".
    • OPENSSL_ROOT_DIR # Set this one to the folder location of the include folder and library folders of OpenSSL.
  • Open a terminal inside the git repo's folder.
  • Run cmake -S . --preset Linux_OR_Windows-Debug_OR_Release.
  • Then run cmake --build --preset Linux_OR_Windows-Debug_OR_Release.
  • Run within the same terminal and folder cmake --install ./Build/Debug_OR_Release.
  • The default installation paths are: Windows = "ROOT_DRIVE:/Users/USERNAME/CMake/DiscordCoreAPI", Linux = "/home/USERNAME/CMake/DiscordCoreAPI"

The CMAKE Package

  • By running cmake --install ./Build/Debug_OR_Release, you will be given a cmake package, which can be used to build from this library, using other cmake projects.
  • It is used by setting DiscordCoreAPI_DIR to wherever the DiscordCoreAPIConfig.cmake file would have been installed on your system by having run the cmake --install command, and then using find_package() on DiscordCoreAPI.
  • When found, you will be granted the following cmake "variables"; DiscordCoreAPI - this is the library target which can be linked to from other targets in cmake, and on Windows; $<TARGET_RUNTIME_DLLS:DiscordCoreAPI-Bot> - which is a list of dll files to be copied into your executable's final location after building. As well as RELEASE_PDB_FILE_PATH, DEBUG_PDB_FILE_PATH, RELEASE_PDB_FILE_NAME, and DEBUG_PDB_FILE_NAME, which are full file/directory paths/filenames to the library's PDB files.
  • Here and here is an example of building an executable from this library with this method.

Build Instructions (Non-Vcpkg) - The Executable

  • Download the bot template or create your own with the same imports, and set within it either the VCPKG_ROOT_DIR, or the CMAKE_CONFIG_FILE_DIR, Opus_DIR, and unofficial-sodium_DIR paths to wherever each of the respective dependency files are located and they are as follows:
    • CMAKE_CONFIG_FILE_DIR # Set this one to the folder location of the DiscordCoreAPIConfig.cmake generated while running CMake --install.
    • Opus_DIR # Set this one to the folder location of the file "OpusConfig.cmake".
    • unofficial-sodium_DIR # Set this one to the folder location of the file "unofficial-sodiumConfig.cmake".
    • OPENSSL_ROOT_DIR # Set this one to the folder location of the include folder and library folders of OpenSSL.
  • Set up a main.cpp like this one, including the header discordcoreapi/Index.hpp.
  • Run in a terminal from within the same folder as the top-level CMakeLists.txt, cmake -S . --preset Linux_OR_Windows-Debug_OR_Release.
  • Then run cmake --build --preset Linux_OR_Windows-Debug_OR_Release.
  • Run within the same terminal and folder cmake --install ./Build/Debug_OR_Release.
  • The default installation paths are: Windows = "ROOT_DRIVE:/Users/USERNAME/CMake/Bot-Template-For-DiscordCoreAPI", Linux = "/home/USERNAME/CMake/Bot-Template-For-DiscordCoreAPI"

Roadmap

I am currently working on getting this thing to be used by people like you! So, if you have any suggestions for the library that would make it more usable - don't hesitate to let me know! I can be easily found on the Discord server that is linked to above! Cheers and thanks for your time.
