Hello, and welcome to DiscordCoreAPI! This is a Discord bot library, written in C++, that leverages custom asynchronous [CoRoutines](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/CoRoutine.hpp), as well as a home-brew set of [Https](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/Utilities/HttpsClient.hpp#L241),
[WebSocket](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/Utilities/WebSocketClient.hpp#L175), and [Datagram](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/VoiceConnection.hpp#L272) 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.
-
```cpp
discord_core_api::snowflake someChannelId{};
discord_core_api::channel_data newChannel = someChannelId.toEntity();
std::cout << "CHANNEL NAME: " + newChannel.name << std::endl;
```
## Performant
----
- Thanks to utilizing [Erlang Text Format](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/Utilities/Etf.hpp) for websocket transfer, and a pool of [kept-alive HTTPS connections](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/Utilities/HttpsClient.hpp#L213) - this library offers the snappiest responses to your interactions and user input.
## 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
----
- As a result of using [custom asynchronous coroutines](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/CoRoutine.hpp) along with a [thread pool](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/Include/discordcoreapi/Utilities/CoRoutineThreadPool.hpp#L70), this library has the ability to make fully asynchronous/concurrent requests to the Discord API.
## 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.
```cpp
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](https://vcpkg.io/en/getting-started.html), 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](https://cmake.org/) (Version 3.20 or greater)
- NOTE: I installed these using the [vcpkg](https://github.com/microsoft/vcpkg) installer.
- [DiscordCoreAPI](https://github.com/RealTimeChris/DiscordCoreAPI) (.\\vcpkg install jsonifier:x64-windows_OR_linux)
- [OpenSSL](https://github.com/openssl/openssl) (.\\vcpkg install openssl:x64-windows_OR_linux)
- [Opus](https://github.com/xiph/opus) (.\\vcpkg install opus:x64-windows_OR_linux)
- [Sodium](https://github.com/jedisct1/libsodium) (.\\vcpkg install libsodium:x64-windows_OR_linux)
# Build Instructions (Non-Vcpkg) - The Library
----
- Install the [dependencies](https://github.com/RealTimeChris/DiscordCoreAPI/blob/main/ReadMe.md#dependencies).
- Clone [this](https://github.com/RealTimeChris/DiscordCoreAPI) 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; `$` - 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](https://github.com/RealTimeChris/Bot-Template-for-DiscordCoreAPI/blob/main/CMakeLists.txt) and [here](https://github.com/RealTimeChris/Bot-Template-for-DiscordCoreAPI/blob/main/Executable/CMakeLists.txt) is an example of building an executable from this library with this method.
# Build Instructions (Non-Vcpkg) - The Executable
----
- Download the [bot template](https://github.com/RealTimeChris/Bot-Template-for-DiscordCoreAPI) or create your own with the same [imports](https://github.com/RealTimeChris/Bot-Template-For-DiscordCoreAPI/blob/main/CMakeLists.txt#L49), 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](https://github.com/RealTimeChris/Bot-Template-for-DiscordCoreAPI/blob/main/main.cpp), 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.
