# input-remapper-switcher

Automatically switches [input-remapper](https://github.com/sezanzeb/input-remapper) presets on a per-game (or per-app) basis when used with the **Hyprland** window manager.

## How It Works

1. Connects to the Hyprland socket (`.socket2.sock`) and listens for `activewindowv2` events.
2. On each window change, it grabs the focused window's **class** and **title** via `hyprctl activewindow -j | jq`.
3. If either value matches a configured entry in the `PROFILES` associative array, it activates the corresponding input-remapper preset on your device.
4. When an unknown window is focused, it deactivates the last active preset.

> Uses `input-remapper-control` under the hood to start/stop presets.

## Adding a Game Profile

1. Find the window class or title of your game:
   - Run `hyprctl clients` and locate the game in the output (class and title are listed for each window)
2. Get the exact name of your input device:
   - `sudo input-remapper-control --list-devices`
3. Edit `input-remapper-switcher.sh` and add an entry to the `PROFILES` array (line 6):

```bash
declare -A PROFILES=(
    ["Grand Theft Auto V"]="GTA"
    ["steam_app_1151340"]="Fallout"
    ["steam_app_1203620"]="Enshrouded"
    # Add yours here:
    ["Your Window Class or Title"]="Your Preset Name"
)
```

4. If your device is different, update `DEVICE_NAME` on line 13:
```bash
DEVICE_NAME="Your Device Name"
```

## Usage

Run the script manually or launch it at Hyprland startup (e.g., in `hyprland.conf`):

```conf
exec-once = ~/.config/hypr/scripts/input-remapper-switcher.sh
```

The script runs in the foreground listening for events — it does not daemonize on its own.
