Sanity clause is a data validation/contract library.  You might use it for configuration data, validating an api response, or documents from a datastore.  In a dynamically typed language, it helps you define clearly defined areas of doubt and uncertainty.  We should love our users, but we should never blindly trust their inputs.

To make use of it, you define schemas, which can be property lists with keys and instances of :class:`sanity-clause.field:field` subclasses as values (eg. :class:`sanity-clause.field:integer-field`, :class:`sanity-clause.field:string-field`, &c.) or using the class-based interface via :class:`sanity-clause.schema:validated-metaclass`.  For example::

   (list :name (make-field :string) :age (make-field :integer))

You can load these sorts of schemas from a file by writing them as sexps with keywords, like this::

  schema.sexp

  (:key (:string :validator (:not-empty) :default "potato")
   :key2 (:integer :validator ((:int :min 0)) :default 2))

and then loading them using :function:`sanity-clause.loadable-schema:load-schema` to load them.


To use class-based schemas using :class:`sanity-clause:validated-metaclass` you can do things like::

   (defclass person ()
        ((favorite-dog :type symbol
                       :field-type :member
                       :members (:wedge :walter)
                       :required t)
         (age :type (integer 0)
              :required t)
         (potato :type string
                 :required t))
        (:metaclass sanity-clause:validated-metaclass))

which will validate their initargs when you instantiate them (**BUT NOT WHEN YOU SET SLOTS**).  Hopefully, that will be added eventually, perhaps as an optional feature.
