This is a Nix flake that installs and configures xremap.

Flake allows running xremap as a system-wide service and as a user service (controlled by services.xremap.serviceMode option).

Flake implements xremap features that allow specifying per-application remapping. Following combinations are tested:

✔️ – tested, works ✖️ – not implemented ❓ – not tested

*: Sway system mode requires restarting the system service after user logs in for the service to pick up the Sway socket.

**: Hyprland feature can be enabled, but the service cannot find a socket

1. Add following to your flake.nix:

   {
       inputs.xremap-flake.url = "github:xremap/nix-flake";
   }

2. Import the xremap-flake.nixosModules.default module.

3. Configure the module options

Alternatively, flake application can be nix run to launch xremap without features.

Following services.xremap options are exposed:

• serviceMode – whether to run as user or system
• withSway – whether to enable Sway support
• withGnome – whether to enable Gnome support
• withX11 – whether to enable X11 support
• package – which package for xremap to use
• config – configuration for xremap defined as Nix attribute set. See original repo for examples.
• userId – user under which Sway IPC socket runs
• userName – Name of user logging into graphical session
• deviceName – the name of the device to be used. To find out the name, you can check /proc/bus/input/devices
• watch – whether to watch for new devices

See examples in nixosConfigurations inside flake.nix.

The nix flake comes with a few VM presets that can be used to test some of the combinations. To run a specific VM:

nix run '.#nixosConfigurations.hyprland-user-dev.config.system.build.vm

where hyprland-user-dev is the name of the nixosConfiguration you want to launch
