CERNY
The Cerny JavaScript library is shipped with solutions for validating JavaScript objects against a schema, pretty printing JSON, logging facilities, dependency management, function call interception and a dictionary mechanism.
Some conventions used:
If a current function or member is overwritten in a script, e.g. 'insertBefore', but will be referred to later, the new name of the member is composed of an underscore followed by the old name, e.g. '_insertBefore'.
If a simple name is not possible due to keyword restrictions, the name is proceeded by an underscore, e.g. '_delete'.
If a function takes arbitrarily many arguments, the documentation for these parameters must be called 'arguments'.
If the documentation for a function does not specify a return value, the function returns undefined.

Functions
object
Prototypal inheritance [DCP].
method
Attach a function as a method to an object. This allows to create arbitrarliy many functions around the actual function. It allows us to keep concerns separated. The interceptors are wrapped around the function starting with the last one. This allows a "natural order", when filling the array regarding dependency. So more basic interceptors (e.g. LogIndenter) are pushed first.
dump
Dump a value for logging purposes. Returns the value of the variable followed by it's type in braces. If the variable is a string, the value is enclosed by a single quote.
intercept
Instrument methods of an object for interception. Can be called multiple times with the same effect, only depending on CERNY.Configuration.Interception.active.
This function does not work on the window object in IE.
namespace
Create a namespace in CERNY. This function is inspired by the Yahoo! UI Library [YUI].
isPresent
Check whether an expression is present during runtime.
require
Check for the presence of expressions.
load
Load a script. This function is called in require. It has different implementations in various environments (browser, Rhino [RHI]).
Dictionary
Dictionary maker.
A dictionary is a mapping from terms to definitions. Definitions can contain nested terms. The process of evaluating a term is done by lookup.
lookup
Lookup a term in this dictionary.
