pipeline_symbols

With pipeline_symbols, you can pipeline ruby symbols as if they are callable (procs and methods).

Installation

Add this line to your application's Gemfile:

gem "pipeline_symbols"

And then execute:

$ bundle install

Or install it yourself as:

$ gem install pipeline_symbols

Usage

Just require pipeline_symobls (require "pipeline_symbols") and chain your symbols like no one is watching!

class User
  attr_reader :id, :name

  def with_default_name
    @name = "John Doe"
    self
  end

  def with_rand_id
    @id = rand(1000)
    self
  end
end

Now instead of writing:

[User.new, User.new].map(&:with_default_name).map(&:with_rand_id)

You can just pipeline the symbols:

[User.new, User.new].map(&:with_default_name >> :with_rand_id)

Chaining of other callable objects (procs and methods) is also supported:

[User.new, User.new].map(&:with_default_name >> :with_rand_id >> ->(user) { user.id })
=> [47, 820]
