Overview

Unified command dispatcher that routes commands to format-specific handlers

The dispatcher is responsible for:

  1. Detecting the format of input files (or using manual override)

  2. Selecting the appropriate format handler from the registry

  3. Delegating command execution to the handler

This class implements the Strategy pattern, where the format handler is the strategy selected based on the detected format.

Examples:

Using the dispatcher

dispatcher = CLI::CommandDispatcher.new(format: :cab, verbose: true)
dispatcher.dispatch(:list, "archive.cab")
