LogBox DSL

In order to create a simple data CFC, just create a CFC with one required method on it called configure where you will define the logging configuration data:

**
* A LogBox configuration data object
*/
component{

    function configure(){
        logBox={

        };
    }
}

Base Config

Once you have this shell, you will create a logBox variable in the variables scope that must be a structure with the following keys:

Key	Description
appenders	A structure where you will define appenders
root	A structure where you will configure the root logger
categories	A structure where you can define granular categories (OPTIONAL)
DEBUG	An array that will hold all the category names to place under the DEBUG logging level (OPTIONAL)
INFO	An array that will hold all the category names to place under the INFO logging level (OPTIONAL)
WARN	An array that will hold all the category names to place under the WARN logging level (OPTIONAL)
ERROR	An array that will hold all the category names to place under the ERROR logging level (OPTIONAL)
FATAL	An array that will hold all the category names to place under the FATAL logging level (OPTIONAL)
OFF	An array that will hold all the category names to not log at all (OPTIONAL)

Appenders

To define an appender you must define a struct with a key value which is the internal name of the appender. Each appender name must be unique. You configure each appender with the following keys:

Key	Description
class	The class path of the appender
properties	The properties struct for the appender (OPTIONAL)
layout	The layout class path of the layout object to use (OPTIONAL)
levelMin	The numerical or English word of the minimal logging level (OPTIONAL, defaults to 0 [FATAL])
levelMax	The numerical or English word of the maximum logging level (OPTIONAL, defaults to 4 [DEBUG])

Root Logger

To configure the root logger use the following keys:

Key	Description
levelMin	The numerical or English word of the minimal logging level (OPTIONAL, defaults to 0 [FATAL])
levelMax	The numerical or English word of the maximum logging level (OPTIONAL, defaults to 4 [DEBUG])
appenders	A string list of the appenders to use for logging

Categories

To define categories you must define a struct with a key value which is the internal name of the category. Each category name must be unique. You configure each category with the following keys:

Key	Description
levelMin	The numerical or English word of the minimal logging level (OPTIONAL, defaults to 0 [FATAL])
levelMax	The numerical or English word of the maximum logging level (OPTIONAL, defaults to 4 [DEBUG])
appenders	A string list of the appenders to use for logging (OPTIONAL, defaults to *)

As you might notice the name of the keys on all the structures match 100% to the programmatic methods you can also use to configure logBox. So when in doubt, refer back to the argument names.

Example Configuration

logBox = {
    // Appenders
    appenders = {
        appenderName = {
            class="class.to.appender",
            layout="class.to.layout",
            levelMin=0,
            levelMax=4,
            properties={
                name  = value,
                prop2 = value 2
            }
    },
    // Root Logger
    root = { levelMin="FATAL", levelMax="DEBUG", appenders="*" },
    // Granualr Categories
    categories={
        "coldbox.system" = { levelMin="FATAL", levelMax="INFO", appenders="*" },
        "model.security" = { levelMax="DEBUG", appenders="console" }
    }
    // Implicit categories
    debug = [ "coldbox.system.interceptors"  ],
    info  = [ "model.class", "model2.class2" ],
    warn  = [ "model.class", "model2.class2" ],
    error = [ "model.class", "model2.class2" ],
    fatal = [ "model.class", "model2.class2" ],
    off   = [ "model.class", "model2.class2" ]
};

Instantiation

Once you have defined the configuration data in this object you can now use the same LogBox Config object to either instantiate it for you or you can pass a reference of it by using the init() method of the LogBoxConfig object:

init([CFCConfig,CFCConfigPath])

• CFCConfig : The object instance that has the logbox configuration data

• CFCConfigPath : The instantiation path of the object that has the logbox configuration data

// Using config path
config = createObject( "component", "logbox.system.logging.config.LogBoxConfig" )
    .init( CFCConfigPath="my.path.LogBoxConfig" );
logBox = createObject( "component", "logbox.system.logging.LogBox" ).init( config );

// Using config object
data = createObject( "component", "my.data.CFC" );
config = createObject( "component", "logbox.system.logging.config.LogBoxConfig" ).init( data );
logBox = createObject( "component", "logbox.system.logging.LogBox" ).init( config );

That's it! Using this DSL approach, your configurations are much more portable now and can even be shared in ANY framework, ColdBox or ColdFusion application. So now let's explore how to bypass this data CFC and use the LogBoxConfig object directly. It is important to understand these methods as they are called for you when you define your LogBox DSL data.
