attr_combined_accessor

Combined reader/writer accessors in Ruby, ideal for chaining or DSLs.

You can install this gem via RubyGems:

gem install attr_combined_accessor

Sometimes you really need to be able to set and get without the limitations of Ruby's default accessors and the equals sign. This is where attr_combined_accessor comes in!

require 'attr_combined_accessor'

class MyAmazingClass
  attr_combined_accessor :foo, :bar
end

And now you can use them:

my_amazing_class = MyAmazingClass.new
my_amazing_class.foo # => nil
my_amazing_class.foo('foo')
my_amazing_class.foo # => 'foo'

The attr_combined_accessor gem returns self from the accessor, which makes chaining setters possible:

my_amazing_class = MyAmazingClass.new
my_amazing_class.foo('foo').bar('bar')
my_amazing_class.foo # => 'foo'
my_amazing_class.bar # => 'bar'

It also creates the standard attr_writer for the places where you want readability and don't need the DSL or chaining style:

my_amazing_class = MyAmazingClass.new
my_amazing_class.foo = 'foo'
my_amazing_class.foo # => 'foo'
my_amazing_class.foo('notfoo!')
my_amazing_class.foo # => 'notfoo!'
