About OPNsense Configuration Processor¶

Project Overview¶

The OPNsense Configuration Processor is a command-line tool designed to bridge the gap between complex XML configuration files and human-readable documentation. Built specifically for network operators and administrators working with OPNsense firewalls, this tool transforms cryptic XML configurations into clear, structured markdown documentation.

Why This Tool Exists¶

Network administrators often need to:

Understand complex configurations quickly during troubleshooting
Document network setups for compliance and knowledge sharing
Review configuration changes in a human-readable format
Work in offline environments where web-based tools aren't available

Traditional approaches involve manually parsing XML files or using web-based converters that require internet connectivity. This tool solves these problems by providing a fast, offline, command-line solution.

Core Principles¶

Operator-Focused Design¶

Every feature is designed with the network operator in mind. Commands are intuitive, output is clear, and workflows match real-world operational needs.

Offline-First Architecture¶

The tool functions completely offline, making it suitable for secure, airgapped environments where many network operations take place.

Structured Data Philosophy¶

All output is structured, versioned, and portable, enabling automated processing and reliable documentation workflows.

Framework-First Development¶

Rather than reinventing the wheel, the tool leverages established Go libraries and follows proven architectural patterns.
