Kernel.js - Command Line Process Manager

Kernel.js is a command-line process manager written in JavaScript. It simulates a basic operating system environment, allowing users to manage processes within virtual folders. Users can start processes, list them, and stop them using simple commands, all through a command-line interface embedded in a web application.

🚀 Features

• Start Processes: Launch processes inside virtual folders.
• List Processes: View all running processes within a specific folder.
• Stop Processes: Stop a process by its unique ID.
• Command-Line Interface: A terminal-like interface for interacting with the system.

🛠️ Installation

Prerequisites

Before you begin, make sure you have the following installed:

• Node.js (v16.x or higher)
• npm (Node Package Manager)

Setup Instructions

1. Clone the repository:

   git clone https://github.com/pawvan/kernel.js.git
   cd kernel.js

2. Install dependencies: If your project requires any dependencies, install them using:

   npm install

3. Run the application: Open the src/markup/index.html file in your web browser. This will load the UI and allow you to interact with the command-line interface.

4. Test the setup: Run the kernel.js script to check if everything is working:

   node src/scripts/kernel.js

⚙️ Usage

Available Commands

• Start a Process:

  start /folder_name process_name

  Example:

  start /folder1 process1

  This command starts a process named process1 in the /folder1 folder.

• List Running Processes in a Folder:

  list /folder_name

  Example:

  list /folder1

  This will display all processes currently running in /folder1.

• Stop a Process by ID:

  stop /folder_name process_id

  Example:

  stop /folder1 1234567890

  This will stop the process with ID 1234567890 in the /folder1 folder.

Example Commands:

1. Start a process:

   start /folder1 process1

2. List processes:

   list /folder1

3. Stop a process by ID:

   stop /folder1 1234567890

📈 Testing

To ensure that the core functionality works as expected, unit tests are provided in the /test directory.

Running the Tests

Run the tests by executing the following command:

npm test

Example Test:

import { kernel } from '../src/scripts/kernel.js';

test('Starting, listing, and stopping processes', () => {
  let result = kernel.handleCommand('start /folder1 process1');
  expect(result).toContain('Started process: process1');

  result = kernel.handleCommand('list /folder1');
  expect(result).toContain('process1');

  const processId = kernel.folders['/folder1'][0].id;
  result = kernel.handleCommand(`stop /folder1 ${processId}`);
  expect(result).toContain('Stopped process');
});

🎯 Roadmap

1. Add Decoding: Implement the decoding functionality to convert byte sequences back into the original string (coming soon).
2. Expand Process Management: Implement features such as pausing and resuming processes.
3. Enhance User Interface: Improve the UI for better user interaction and visual feedback.
4. Cross-platform Support: Ensure the command-line interface works on all major operating systems (Windows, macOS, Linux).
