pykeepalive 0.1.1

Keep your system awake by simulating mouse activity

pykeepalive

A simple Python tool that keeps your system awake by making tiny periodic mouse movements.

Description

pykeepalive prevents your computer from going to sleep by simulating user activity through small, random mouse movements. It's useful for:

• Preventing screensaver activation
• Avoiding system sleep during long-running tasks
• Keeping remote sessions active
• Testing scenarios that require system activity

Installation

Prerequisites

• Python 3.12 or higher

Install from PyPI

pip install pykeepalive

Install from source

git clone <repository-url>
cd pykeepalive
uv sync

Usage

Basic Usage

Run the tool to keep your system awake indefinitely:

uv run pykeepalive

The tool will start moving your mouse cursor slightly every 20-60 seconds. Press Ctrl+C to stop.

Command Line Options

• --min-interval INTEGER: Minimum interval between movements in seconds (default: 20)
• --max-interval INTEGER: Maximum interval between movements in seconds (default: 60)
• --duration INTEGER: Run for this many seconds, then stop automatically (useful for testing)

Examples

Run with custom intervals:

uv run pykeepalive --min-interval 10 --max-interval 30

Test for 10 seconds:

uv run pykeepalive --duration 10

How It Works

The tool uses the pynput library to control the mouse cursor. Every random interval (between min and max seconds), it moves the cursor by a small random amount (-2 to +2 pixels in both x and y directions). This tiny movement is usually imperceptible but prevents the system from detecting inactivity.

Testing

To verify the tool is working:

1. Visual Test: Run uv run pykeepalive --duration 10 and watch your mouse cursor - it should move slightly every few seconds.

2. Position Check: Use this Python snippet to monitor mouse position:

   from pynput.mouse import Controller
   import time
   
   mouse = Controller()
   print(f"Before: {mouse.position}")
   time.sleep(5)
   print(f"After: {mouse.position}")
   

3. System Sleep Test: Set your system to sleep after 1-2 minutes, run pykeepalive, and verify the system stays awake.

Requirements

• pynput>=1.8.1: For mouse control
• typer>=0.9.0: For command-line interface
