Layout Fixer

A native GNOME extension designed for Wayland that instantly corrects text typed in the wrong keyboard layout (EN ↔ UA).

✨ Features

• Native Wayland Support: Uses Clutter.VirtualDevice to emit keystrokes. No uinput or root privileges required.
• Clipboard Protection: Automatically saves and restores your previous clipboard content after reclacing the text.
• GUI Configuration: Easily bind a custom shortcut (default is Alt+A) via the built-in preferences using an interactive key recorder.
• Zero Dependencies: Built using pure GJS and GNOME APIs.

📦 Compatibility

• GNOME Shell: 50
• Session: Wayland (X11 is supported but optimized for Wayland architecture).

🛠️ Installation

Manual Installation

1. Clone the repository:

   git clone https://github.com/git-hntr/layout-fixer.git

2. Create the extension directory:

   mkdir -p ~/.local/share/gnome-shell/extensions/layout-fixer@hntr

3. Copy the files:

   cp -r layout-fixer/* ~/.local/share/gnome-shell/extensions/layout-fixer@hntr/

4. Compile the GSettings schemas:

   glib-compile-schemas ~/.local/share/gnome-shell/extensions/layout-fixer@hntr/schemas/

5. Log out and log back in. (Crucial step for GNOME on Wayland to detect new local extensions).
6. Enable the extension using the Extension Manager app or via terminal:

   gnome-extensions enable layout-fixer@hntr

⚙️ How It Works (Under the Hood)

Due to Wayland's strict security model, applications cannot inject text into other windows directly. This extension runs with compositor privileges and performs the following micro-operations in less than half a second:

1. Reads and backs up the current St.Clipboard state.
2. Emits a synthetic Ctrl+C event via Clutter.VirtualDevice to capture the selected text.
3. Analyzes the string and performs EN ↔ UA transliteration.
4. Writes the corrected text to the clipboard and emits Ctrl+V.
5. Restores the original clipboard content after a brief delay.

🔧 Configuration

1. Open Extension Manager.
2. Click the gear icon (⚙️) next to Layout Fixer.
3. Click "Record" and press your desired key combination. Changes apply instantly.
