dissmatch v0.0.1

#Dissmatch negatively match objects (note: this documentation is in a very rough state. Many parts are illegible.) ##About It is often infiesable to match entire objects. Dissmatch does not try to match the whole object. Instead, it matches a given object agains a pattern and returns a value only when there is a violation of the pattern. If there are parts of the object that are not defined in the pattern, dismatch simply ignores them.

##Installation In your project's directory on the command line:

npm install --save dissmatch

In your project file:

var dissmatch = require('dissmatch');
//work your magic here...

##API

###dissmatch is a single function:

/**
*
*@param subject - Object
*@param pattern - Object
*/
var dissmatch = function(subject, pattern,[pattern2, pattern3...])

###subject subject can be any javascript object

###Pattern pattern is a specifically designed javascript object. Multiple patterns can be included and will be matched sequentially.

var matchErrors =
  dissmatch(subject, pattern1) ||
  dissmatch(subject, pattern2) ||
  dissmatch(subject, pattern3);

is equivalent to

var matchErrors =
  dissmatch(
    subject, pattern1, pattern2, pattern3);

####Types Each key within a pattern points to an object. The type of object determines how it matches against the value at the same key in the original subject.

#####Boolean Booleans define presence

• true -- return an error only if the key DOES NOT exist
• false -- return an error only if the key DOES exist

#####RegExp Regular Expressions will return an error only if the value in the subject DOES NOT match.

#####Array Expect an error only if the original value is not equal (===) to at least one of the values in the array. Functions take two arguments, the value and the subject (value, subject) => :Error?

#####Function Functions can define complex behavior and should be used with caution. Other Types can be simulated/extended using functions. Functions SHOULD be designed to evaluate a value and return a error only if the value fails evaluation. Functions take two arguments, the value and the subject (value, subject) => :Error?

#####Object Nesting patterns within objects allows the testing of nested subjects.
