Overview

Abstract base class for all CLI commands.

Provides common functionality for loading fonts using FontLoader for automatic format detection. Works polymorphically with TrueTypeFont and OpenTypeFont instances.

Subclasses must implement the run method to define command-specific behavior.

Examples:

Creating a command subclass

class MyCommand < BaseCommand
  def run
    info = Models::FontInfo.new
    info.family_name = font.table("name").english_name(Tables::Name::FAMILY)
    info
  end
end
