D++ Extremely Lightweight C++ Discord Library

Overview

D++

An incredibly lightweight C++ Discord library

This project is in alpha stages of development.

Completed so far:

  • Websocket connection with heartbeat keepalive and connection resuming
  • Caching system for guilds, channels, guild members, roles, users
  • Event dispatcher - currently only dispatches a subset of messages including e.g. on_message_create and on_guild_create
  • Ability to attach handlers to events
  • REST HTTPS call system using cpp-httplib
  • Message send (dpp::cluster::message_create())
  • Embeds
  • Ratelimit system
  • Windows support

To do:

  • Add the rest of the discord events
  • Add the REST of the HTTP calls (pun intended)
  • Ability to receive raw json strings to event handlers
  • Shard manager
  • Cluster management
  • File uploading

Want to help? Drop me a line or send me a PR. I'll be choosy about what PRs i accept whilst the library is in such a heavy state of development.

It is my intention to get this stable enough to use on my production bot, TriviaBot.

Documentation

Documentation will be here in the project wiki when the project is more complete.

Supported OSes

The library runs best on Linux. Windows is supported via cmake and Visual Studio 2019 but not encouraged for production use. The library may work fine in other operating systems too, but with no access to these we cannot support them.

Dependencies

External Dependencies (You must install these)

  • cmake (version 3.13+)
  • g++ (version 8+)
  • OpenSSL (whichever -dev package comes with your OS)

Included Dependencies (Packaged with the library)

Linux Setup

1. Build Source Code

mkdir build
cd build
cmake ..
make -j8

Replace the number after -j with a number suitable for your setup, usually the same as the number of cores on your machine. cmake will fetch any dependencies that are required for you and ensure they are compiled alongside the library.

2. Run test cases

run ./test for unit test cases.

3. Install to /usr/local/include and /usr/local/lib

make install coming soon!

    Any chance of a pre-compiled 32-bit version for Windows?

    My intended application to use D++ in, is currently built for 32-bit.

    I followed the build instructions in the Documentation and it defaults to x64 debug. My attempts at switching to 32-bit architecture haven't worked thus far, and using CMake-Gui to generate a solution (which deviates from the recommended build procedure) appears to cause some unresolved external symbol issues. Perhaps because the packaged libraries are all x64?

  • missing heartbeat handling?

    missing heartbeat handling?

    Describe the bug Instead of sending a heartbeat to the discord servers every ~40 seconds the connection is shutdown with code 1000 every minute (and immediately reconnected). After the connection is closed unexpectedly (eg. TCP error) the disconnect seems to be unhandled.

    To Reproduce I noticed the disconnect issue after I suspended my computer. After wakeup the bot was naturally disconnected from discord servers but the library never noticed or fixed this. All logs (even trace) stay empty.

    Expected behavior

    • According to Discord documentation: first heartbeat after a random duration <= heartbeat_interval, subsequently one haertbeat every heartbeat_interval milliseconds.
    • Automatic resume, on failure reconnect if the connection is closed without a terminating message by discord servers.

    System Details:

    • used commit 02cd5aa908cf614c9c6fe27aa3bff8ac9092f041 to test

    dpp::cluster::thread_create_in_forum() crashes the bot without a clear error when the bot has insufficient permissions

    Git commit reference d4b74dae5a3fd7d2f7e9f458c90c16c4fc4fa588

    Describe the bug When dpp::cluster::thread_create_in_forum() is used in a channel where the bot does not have the correct permissions to create a post, the bot crashes without any clear errors (see screenshot further down).

    Steps to reproduce the behavior: run dpp::cluster::thread_create_in_forum() on a channel the bot does not have the Create Posts permission for

    Expected behavior Something along the lines of what bot.message_create() would do in the case of missing permissions: Outputting an error code along with the API response to the terminal, showing that the bot does not have the correct permissions. And most importantly, not crash the bot in the process.

    Currently however, the bot just terminates with little information about the reason, see screenshot image

  • Audio artifacts when streaming uncompressed audio w/ send_audio_raw

    Audio artifacts when streaming uncompressed audio w/ send_audio_raw

    Running tip, 45c509fb763f0b6d34494d546c802986ac15d648.

    I'm trying to stream uncompressed PCM audio into DPP in this manner:

    const int kAudioBufferCount = 4; // length of the audio buffer chain in DPP
    
    bot.on_voice_buffer_send([&](const dpp::voice_buffer_send_t& event) {
    	int buffer_size = event.buffer_size;
    
    	while (buffer_size < kAudioBufferCount) {
    		// Get exactly 11520 bytes of 48khz, stereo, signed 16-bit PCM
    		PCM block = PopAudio();
    
    		event.voice_client->send_audio_raw((uint16_t*)block.data, block.size);
    
    		++buffer_size;
    	}
    });
    

    This nearly works - I hear the streamed sound from Discord Web - but there are frequent glitches.

    I added some code to measure the rate at which I'm passing samples into DPP and measuring ~47364 Hz, not 48k. I'm definitely not underflowing -- event.buffer_size doesn't drop below 3.

    The artifacts sound like skipped chunks waveform to me, not resampling.

    Any idea why DPP would be requesting at less than the full rate? Or is the above call pattern incorrect for a streaming use case?

    Package manager support

    Is your feature request related to a problem? Please describe. Vcpkg or conan support help alleviate the setup for multiple libraries in a project. They help to get started quickly with a framework while still allowing other libraries to be added quickly.

    Describe the solution you'd like Rather than premade build setups, I think that having vcpkg or conan support would enable more ambitious discord bots to be created faster.

    Describe alternatives you've considered
