Description

Utility methods for accessor-related meta-programming.

Summary

Extends String and Symbol instances with variable/accessor methods, provides swizzling helpers, provides accessor-related math for transforming :accessor, :reader, :writer.

AccessorUtilities::AccessorMath

Given attribute accessor types :accessor, :reader, :writer:

:status_plus_other_status

• status_plus_other_status( :accessor, :reader ) = :accessor
• status_plus_other_status( :accessor, :writer ) = :accessor
• status_plus_other_status( :reader, :writer ) = :accessor
• status_plus_other_status( :reader, :reader ) = :reader

:status_minus_other_status

• status_minus_other_status( :accessor, :reader ) = :writer
• status_minus_other_status( :accessor, :writer ) = :reader
• status_minus_other_status( :reader, :writer ) = :reader
• status_minus_other_status( :reader, :reader ) = nil

AccessorUtilities::Swizzle

Given a class with a method defined:

class ExampleClass

  def some_method
    return :first_value
  end

end

Swizzle methods within the present context:

class ExampleClass

  include AccessorUtilities::Swizzle

  swizzle_method( :some_method ) do
    :second_value
  end

end

Result is method call invokes block used to swizzle method:

class ExampleClass

  self.some_method
  # => :second_value

end

AccessorUtilities::StringInstance and AccessorUtilities::SymbolInstance

• is_variable_name?
• variable_name
• accessor_name
• write_accessor_name
• swizzle_name

Install

• sudo gem install accessor-utilities
