Abaddon

---

Alternative Discord client made in C++ with GTK

Current features:

• Not Electron
• Handles most types of chat messages including embeds, images, and replies
• Completely styleable/customizable with CSS (if you have a system GTK theme it won't really use it though)
• Identifies to Discord as the web client unlike other clients so less likely to be falsely flagged as spam¹
• Set status
• Start new DMs and group DMs
• View user profiles (notes, mutual servers, mutual friends)
• Kick, ban, and unban members
• Modify roles and modify members' roles
• Manage invites
• Manage emojis
• View audit log
• Emojis²
• Thread support³
• Animated avatars, server icons, emojis (can be turned off)

1 - Abaddon tries its best to make Discord think it's a legitimate web client. Some of the things done to do this include: using a browser user agent, sending the same IDENTIFY message that the official web client does, using API v9 endpoints in all cases, and not using endpoints the web client does not normally use. There are still a few smaller inconsistencies, however. For example the web client sends lots of telemetry via the /science endpoint (uBlock origin stops this) as well as in the headers of all requests. In any case, you should use an official client for joining servers, sending new DMs, or managing your friends list if you are afraid of being caught in Discord's spam filters (unlikely).

2 - Unicode emojis are substituted manually as opposed to rendered by GTK on non-Windows platforms. This can be changed with the stock_emojis setting as shown at the bottom of this README. A CBDT-based font using Twemoji is provided to allow GTK to render emojis natively on Windows.

3 - There are some inconsistencies with thread state that might be encountered in some more uncommon cases, but they are the result of fundamental issues with Discord's thread implementation.

Building manually (recommended if not on Windows):

Windows:

1. git clone https://github.com/uowuo/abaddon && cd abaddon
2. vcpkg install gtkmm:x64-windows nlohmann-json:x64-windows ixwebsocket:x64-windows zlib:x64-windows sqlite3:x64-windows openssl:x64-windows curl:x64-windows
3. mkdir build && cd build
4. cmake -G"Visual Studio 16 2019" -A x64 -DCMAKE_TOOLCHAIN_FILE=c:\path\to\vcpkg\scripts\buildsystems\vcpkg.cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DVCPKG_TARGET_TRIPLET=x64-windows ..
5. Build with Visual Studio

Or, do steps 1 and 2, and open CMakeLists.txt in Visual Studio if vcpkg integrate install was run

Mac:

1. git clone https://github.com/uowuo/abaddon && cd abaddon
2. brew install gtkmm3 nlohmann-json
3. mkdir build && cd build
4. cmake ..
5. make

Linux:

1. Install dependencies: libgtkmm-3.0-dev, libcurl4-gnutls-dev, and nlohmann-json
2. git clone https://github.com/uowuo/abaddon && cd abaddon
3. mkdir build && cd build
4. cmake ..
5. make

Latest release version: https://github.com/uowuo/abaddon/releases/latest

CI:

• Windows: here
• MacOS: here unsigned, unpackaged, requires gtkmm3 (e.g. from homebrew)
• Linux: here unpackaged (for now), requires gtkmm3. built on Ubuntu 18.04 + gcc9

⚠️ If you use Windows, make sure to start from the directory containing css and res

On Linux, css and res can also be loaded from ~/.local/share/abaddon or /usr/share/abaddon

abaddon.ini will also be automatically used if located at ~/.config/abaddon/abaddon.ini and there is no abaddon.ini in the working directory

Settings

Settings are configured (for now) by editing abaddon.ini
The format is similar to the standard Windows ini format except:

• # is used to begin comments as opposed to ;
• Section and key names are case-sensitive

You should edit these while the client is closed even though there's an option to reload while running
This listing is organized by section.
