Valuedate

Validates values using a schema.

Source | RDoc | Metrics

Usage

schema = Valuedate.schema do
value.is_a(String).equals("test")
end

schema.validate("test") # => true
schema.validate("fail") # => false
schema.validate(23) # => false

deep = Valuedate.schema do
value.hash(
  :type => value.is_a(String),
  :value => value.hash(
    :src => value.is_a(String),
    :height => optional_value.is_a(Fixnum),
    :width => optional_value.is_a(Fixnum)
  )
)
end

deep.validate(
:type => "image",
:value => {
  :src => "/bold.gif",
  :height => 80,
  :width => 80
}
) # => true

# :height and width are optional
deep.validate(:type => "image", :value => { :src => "/bold.gif" }) # => true

Matchers

Following matchers are defined:

• is_a(Class)
• equals(expected)
• any(list of validators)
• in(range, array or anything that responds_to #include?)
• is { |value| boolean }
• not { |value| boolean }

Missing matchers?

Use #is and #not:

schema = Valuedate.schema do
value.hash(
  :array  => value.not { |value| value.empty? },
  :rgb    => value.is { |value| value.size == 3 }
)
end

schema.validate(:array => [1], :rgb => [1,2,3]) # => true
schema.validate(:array => [1], :rgb => [1,2]) # => false

Defining matchers

Valuedate.matcher(:equals) { |value, expected| value == expected }
