ActiveObject [WIP]

A Ruby library that provides dynamic method generation and array operations for hash-like objects.

Features

• Dynamic method generation for hash keys
• Array operations for array values:
  • first_* - Get first element
  • last_* - Get last element
  • average_* - Calculate average
  • min_* - Find minimum value
  • max_* - Find maximum value
  • *_at - Access element by index
  • sum_* - Calculate sum
  • sort_* - Sort array
  • count_* - Count elements

Usage

require 'active_object'
require 'active_support/inflector'

# Create an ActiveObject with hash data
data = {
  name: "Cormen's algorithm book - 2nd edition",
  authors: ['Maria', 'John', 'Jeff'],
  recommended_prices: [100.0, 80.0, 59.5, 120.0]
}

book = ActiveObject.new(data)

# Access attributes directly
book.name                    # => "Cormen's algorithm book - 2nd edition"
book.authors                 # => ['Maria', 'John', 'Jeff']

# Array operations
book.first_author           # => "Maria"
book.last_author            # => "Jeff"
book.author_at(1)           # => "John"
book.count_authors          # => 3
book.sum_recommended_prices # => 359.5
book.sort_recommended_prices # => [59.5, 80.0, 100.0, 120.0]
book.average_recommended_price # => 89.875
book.max_recommended_price  # => 120.0
book.min_recommended_price  # => 59.5

Requirements

• Ruby
• ActiveSupport (for string inflection)
