Bornika is a lightweight, secure, pure-Rust background Input Method Editor (IME) for Linux. Designed natively for modern desktop systems (like Fedora running Wayland and GNOME), it allows typing Bangla phonetically using a standard QWERTY layout.

By connecting directly to the IBus (Intelligent Input Bus) framework over the system's private D-Bus socket, Bornika runs entirely in user space without requiring root privileges or installing heavy C development libraries.

• Complete Avro Phonetic Support: Fully supports all standard phonetic combinations (e.g., kotha $\rightarrow$ কথা, kOtha $\rightarrow$ কোথা, rri $\rightarrow$ ঋ, S $\rightarrow$ শ, Sh $\rightarrow$ ষ, borrd $\rightarrow$ বর্ড).
• Wayland & X11 Native: Native compatibility across all window servers by leveraging the IBus system service.
• Pure Rust Architecture: Built using tokio and zbus to connect directly over D-Bus. No dynamic link bindings (libibus-devel, glib2-devel) are required to compile.
• On-the-Fly Toggle: Press Super + Space within any active text input to toggle between English and Bangla phonetic modes.
• Real-time Composition Styling: Displays uncommitted text inline with a composition underline, guaranteeing native visual feedback in modern editors (like VS Code, Chrome, Firefox, and GTK text fields).
• Shortcut & Control Pass-through: Standard layout operations (like Ctrl + C, Ctrl + V, Ctrl + A, Space, Enter) bypass phonetic interception automatically.

Bornika follows the standard Avro phonetic transliteration guidelines:

• Fedora (or any Linux distribution running IBus).

To download and install the latest pre-built release of Bornika directly on your system, run:

curl -fsSL https://raw.githubusercontent.com/itsfuad/Bornika/main/install.sh | sh

This script automatically:

1. Downloads the latest pre-built bornika-daemon binary from GitHub Releases.
2. Deploys the background binary to ~/.local/bin/bornika-daemon.
3. Registers the Bornika engine template at /usr/share/ibus/component/bornika.xml (requires one-time sudo authentication to copy to the system directory).
4. Restarts the active IBus daemon session to load the engine.

If you prefer to compile and install Bornika from source, you will need the Rust toolchain (Cargo & Rustc) installed. Clone the repository and run:

./build.sh

Once installed, register Bornika as an active Input Source in your desktop environment:

1. Open your system's Settings (e.g. GNOME Settings).
2. Navigate to Keyboard $\rightarrow$ Input Sources.
3. Click the + (Add) button.
4. Select Bengali $\rightarrow$ Bengali (Bornika) and click Add.
5. Switch to the Bornika input source from your top-bar menu or press Super + Space.
