I was looking for a really simple factory gem, such as factory_girl, but without any magic to use with rails. I was incompetent at that, so I built this really simple factory called IceCream.

The Idea

The central idea is to have a very simple file to describe what you want to fabricate. When I say simple, I mean SIMPLE. The file is just a "file.flavor" (plain text) with two collums: variable and default value.

This gem goes to the factory directory and for each ".flavor" file, it creates a class (with the given file name) and fills this class with instance variables for each one of the values declared.

Imagine a file called chocolate.flavor that has the following content:

name = "Chocolate"
colour = :brown
calories = 150
price = 15.5

After that, you can call the IceCream factory using the following commands:

$ IceCream.flavor :chocolate

and it is going to return a Chocolate (class) object called chocolate, with a string, a symbol, a float and an integer. Easy ;)

It works in your non-Rails Ruby project as well. It's just Ruby code, and there is not a single dependency (so far).

Installing

Terminal

$ gem install icecream

Gemfile

$ gem 'icecream'

Using

You can have different folders (fridges) with different factories definitions as exemplified bellow:

$ require 'icecream'
$ creamy_flavors = IceCream::Icecream.new "/path/to/flavors"
$ cheap_chocolate = creamy_flavors.flavor :chocolate
$ cheap_chocolate.name= "whathever you want :)"
# You can have as many "factories" as you need
$ diet_flavors = IceCream::Icecream.new "/path/to/Diet/flavors"
$ zero_sugar_chocolate = diet_flavors.flavor :chocolate

You can also, define an object from nowhere, creating it with a single line!

$ IceCream::IceCream.flavor :Orange, "[name = 'orange', color = :orange, price = 35.5, calories = 3]"

If you are working with big sets of data, you can update information of an object with the information of another object using merge. For instance:

$ chocolate = @fridge.flavor :chocolate
# it has: name => "chocolate", color => :brown, price => 15.5 and calories => 150.

$ update = IceCream::IceCream.flavor :Update_chocolate, "[name = 'Dark Chocolate', price = 55.5]"
# you created a new object with part of the data that chocolate has

$ IceCream::IceCream.merge chocolate, update
$ chocolate
# returns: name => "Dark Chocolate", color => :brown, price => 55.5 and calories => 150.

Have fun!
