Wine Discord IPC Bridge

This program enables other programs which are running under Wine to send Rich Presence data to a Linux Discord client.

This is mainly a proof-of-concept, demonstrating that this is possible, the code itself is a mish-mash of copy-paste from Microsoft docs and linux-discord-rpc.dll.

The way it works is simply by bridging the gap between Windows named pipes (\\.\pipe\discord-ipc-0) and Unix domain sockets (/run/user/{userid}/discord-ipc-0).

Compiling

i686-w64-mingw32-gcc -masm=intel main.c -o winediscordipcbridge

Usage (Wine)

Start the bridge first, wait for it to start listening to the pipe, and then launch your program/game. The two programs need to be running under the same wineprefix.

Usage (Steam Proton)

1. Download winediscordipcbridge-steam.sh and place it in the same directory as winediscordipcbridge.exe. Use chmod +x to make it executable if necessary.

2. In the game's settings on Steam, edit "Launch Options" to /path/to/winediscordipcbridge-steam.sh %command%. You will have to do this for every game that supports Rich Presence.

This currently starts the bridge in the background to act as a 'debugger' before the game starts and opens up the folder the Linux Discord socket lives in to be read/write. This worked for Deep Rock Galactic, hopefully the timing of the bridge works correctly for other games.

The bridge should automatically stop once the connecting program terminates, although it'll keep running if nothing ever connects.

I've personally tested this with osu! on both 32-bit and 64-bit wineprefixes, and Muse Dash using the script to launch from Steam with Proton Experimental.
