📖 About the Project

Host Profiles Manager is a cross-platform desktop application that provides a modern and intuitive interface for managing your system's hosts file. It allows you to create, switch between, and manage multiple host profiles, making it easy to handle different network configurations (e.g., development, staging, production).

The application is built entirely in Rust using the Iced GUI framework and a SQLite database for persistent profile storage.

✨ Key Features

• Profile Management: Create, select, update, and delete multiple host profiles.
• Persistent Storage: All profiles and their host entries are saved to a SQLite database, ensuring your data is retained between sessions.
• DNS Lookup: Easily add new host entries by performing a DNS lookup for a given hostname.
• Manual Entry: Manually add or edit host entries with specific IP addresses and hostnames.
• Seamless Editing: Modify existing entries directly within the UI, with changes saved automatically to your profile and the hosts file.
• Import/Export Profiles: Share your host configurations by exporting profiles to a .json file and importing them on another machine.
• Cross-Platform Compatibility: The application is designed to work on Windows, macOS, and Linux. It correctly identifies the OS to manage the hosts file and application data paths.
• System Permissions Handling: The application requires administrative privileges to modify the hosts file, and it handles the required permissions gracefully on each platform.

🚀 Getting Started

Prerequisites

• Rust (latest stable version)
• Git

Building from Source

1. Clone the repository:

   git clone https://github.com/YOUR_USERNAME/YOUR_REPO_NAME.git
   cd YOUR_REPO_NAME

2. Build the application in release mode:

   cargo build --release

   The executable will be located in target/release/.

Running the Application

Since the application needs to modify the system hosts file, it must be run with administrative privileges.

• Linux/macOS:

  sudo ./target/release/hosts_manager

  You will be prompted for your password.

• Windows: Navigate to the target/release/ folder, right-click hosts_manager.exe, and select "Run as administrator".
