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 simply 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). Ideally something like this would be implemented in wine itself, it should be possible to add some sort of "mapped named pipe" feature where wineserver will serve handles to unix sockets instead pseudo-handles to named pipes, but I don't know how to approach something like that.

Compiling

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

Usage

Run make install to install the bridge as a service that runs automatically. You can change the wine binary and wineprefix of the installation by setting the WINE and WINEPREFIX variables respectively.

For example, to install the bridge under the default Proton 5.0 prefix:

make install WINE=~/.steam/root/steamapps/common/Proton\ 5.0/dist/bin/wine \
  WINEPREFIX=~/.steam/root/steamapps/common/Proton\ 5.0/dist/share/default_pfx

You can uninstall the service by running make uninstall. You must use the same WINE and WINEPREFIX variables you used to install it.

Disclaimer

This has only been tested under a 32-bit wineprefix.
