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 gateway 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
• Animated avatars, server icons, emojis (can be turned off)

1 - Other third-party clients send the IDENTIFY message that bots use which makes Discord more likely to think you are selfbotting or spamming. However, Discord still loves to ban people's accounts for no good reason, even users of the official clients. If you want to be really careful avoid joining servers really fast or cold DMing people.
2 - Getting emojis to function properly on GTK is still something I've yet to figure out (#5). Unicode emojis are manually searched for and replaced in several places as opposed to allowing GTK to figure it out since GTK's way of doing it doesn't work very well.

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 simpleini: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

1. git clone https://github.com/uowuo/abaddon && cd abaddon
2. brew install gtkmm3 nlohmann-json

2. git clone https://github.com/uowuo/abaddon && cd abaddon
3. mkdir build && cd build
4. cmake ..
5. make

Settings

Settings are configured (for now) by editing abaddon.ini
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.
For example, memory_db would be set by adding memory_db = true under the line [discord]

discord

• memory_db (true or false, default false) - if true, Discord data will be kept in memory as opposed to on disk
• token (string) - Discord token used to login, this can be set from the menu
• prefetch (true or false, default false) - if true, new messages will cause the avatar and image attachments to be automatically downloaded

http

• user_agent (string) - sets the user-agent to use in HTTP requests to the Discord API (not including media/images)
• concurrent (int, default 10) - how many images can be concurrently retrieved

gui

• member_list_discriminator (true or false, default true) - show user discriminators in the member list
• emojis (true or false, default true) - resolve unicode and custom emojis to images. this needs to be false to allow GTK to render emojis by itself
• css (string) - path to the main CSS file
• animations (true or false, default true) - use animated images where available (e.g. server icons, emojis, avatars). false means static images will be used
• owner_crown (true or false, default true) - show a crown next to the owner
