Works by running a small program in the background that creates a named pipe \\.\pipe\discord-ipc-0 inside the prefix and forwards all data to the pipe /run/user/1000/discord-ipc-0.

This bridge takes advantage of the Windows service implementation in Wine, eliminating the need to manually run any programs.

Discord RPC Bridge for Wine

Installation & Usage

Installation will place bridge.exe to C:\bridge.exe (if it's not already there) and create a Windows service. This service will automatically start when the prefix is used.

If you prefer not to use the service for any reason, please refer to the Run without installing the service section.

Installing inside a prefix

Wine (~/.wine)

Open terminal in build
Run $ wine cmd and C:\> install.bat
To remove, run C:\> remove.bat
Note: Copying files are not required here.

Lutris

Right click on the game and select Browse files
Copy contents of build to the game's prefix drive_c
To install open the console
And run C:\> install.bat (make sure you are in C:\!)

Steam

Open Protontricks and select the game you want to install the bridge to
Select Select the default wineprefix
Select Browse files and copy contents of build to the game's prefix drive_c
Select Run a Wine cmd shell and run C:\> install.bat
- If you are not in C:\, type c: and press enter

If you use Flatpak

If you are running Steam, Lutris, etc. in a Flatpak, you will need to allow the bridge to access the /run/user/1000/discord-ipc-0 file.
- By using Flatseal
  - Add xdg-run/discord-ipc-0 under Filesystems category
- By using the terminal
  - Per application
    - flatpak override --filesystem=xdg-run/discord-ipc-0 <flatpak app name>
  - Globally
    - flatpak override --user --filesystem=xdg-run/discord-ipc-0

Run without installing the service

If you prefer not to use the service, you can manually run bridge.exe within the Wine prefix. This method is compatible with both Wine and Lutris.

In Lutris, you can achieve this by adding the path to bridge.exe in the Executable field under Game options. In Arguments field, be sure to include the Windows path to the game's executable. Example:

Without bridge:
- Executable /mnt/games/lutris/league-of-legends/drive_c/Riot Games/League of Legends/LeagueClient.exe
- Arguments --locale=en_US --launch-product=league_of_legends --launch-patchline=live
With bridge:
- Executable /mnt/games/lutris/league-of-legends/drive_c/bridge.exe
- Arguments "C:\Riot Games\League of Legends\LeagueClient.exe" --locale=en_US --launch-product=league_of_legends --launch-patchline=live

In Wine, all you need to do is run bridge.exe.

When running the program manually without providing any arguments, it will simply initiate the bridge and wait indefinitely until it's closed.

About macOS

The bridge works similarly on macOS as it does on Linux, but it can't be registered as a service due to TMPDIR limitations. macOS users must manually run bridge.exe when needed.

To run bridge.exe on macOS, navigate to its directory in the terminal and execute wine bridge.exe. (or double click it in the Finder)

Compiling from source

Install the wine, x86_64-w64-mingw32-gcc and make packages.
Open a terminal in the directory that contains this file and run make.
The compiled executable will be located in build/bridge.exe.

Command line arguments

--install - Installs the service
--remove - Removes the service
--service - Reserved for the service
[Target Executable] - Starts the bridge and the game
- Example: bridge.exe "C:\Riot Games\League of Legends\LeagueClient.exe" --locale=en_US --launch-product=league_of_legends --launch-patchline=live
- Note: The game executable must be enclosed in quotes. The rest of the arguments are passed to the target executable.

Debugging

The bridge will write the logs in C:\bridge.log.
