rs-uinput-kb 0.1.0

A Python wrapper for Linux /dev/uinput keystroke simulation

rs_uinput

rs_uinput is a Python library backed by Rust that types text through Linux's uinput subsystem.

Instead of injecting keystrokes into a specific application, it creates a virtual keyboard device and sends real keyboard events through the Linux input stack.

Example

import rs_uinput

rs_uinput.type_text(
    text="Hello, world!",
    min_delay=0.05,
    max_delay=0.15
)

How It Works

1. Python calls the Rust extension through PyO3.
2. Rust creates a virtual keyboard using /dev/uinput.
3. Each character is converted into the corresponding Linux key code.
4. Key press and key release events are sent through the kernel.
5. A random delay is applied between characters.

How It Differs From pynput

pynput typically relies on higher-level desktop APIs (X11, Wayland compatibility layers, platform-specific event injection APIs, etc.).

rs_uinput operates at the Linux input-device layer by creating a virtual keyboard device.

Because it acts as an input device, applications receive the events through the normal Linux input pipeline rather than through a specific GUI automation API.

How It Differs From Selenium

Selenium does not generate system-wide keyboard input.

Instead, Selenium controls a web browser through the browser's automation interface:

This means Selenium can only interact with browser content that it controls.

rs_uinput generates keyboard events at the operating-system level, allowing text to be entered into any focused application that accepts keyboard input.
