motion_coercible
A RubyMotion port of solnic's coercible library.
Installation
Add this line to your application's Gemfile:
gem 'motion_coercible'
And then execute:
$ bundle
Or install it yourself as:
$ gem install motion_coercible
Usage
Coercible gives you access to coercer objects where each object is responsible for coercing only one type into other types. For example a string coercer knows only how to coerce string objects, integer coercer knows only how to coerce integers etc.
Here's the most basic example:
coercer = Coercible::Coercer.new
# coerce a string to a date
coercer[String].to_date('2012/12/25') # => #<Date: 4912573/2,0,2299161>
# coerce a string to a boolean value
coercer[String].to_boolean('yes') # => true
# you got the idea :)
For more control you can configure your coercer like that:
# build coercer instance
coercer = Coercible::Coercer.new do |config|
config.string.boolean_map = { 'yup' => true, 'nope' => false }
end
# coerce a string to boolean
coercer[String].to_boolean('yup') # => true
coercer[String].to_boolean('nope') # => false
Note that at the moment only Integer and String are configurable. More configurable coercers will be added later whenever we find good usecases.
