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:
1
**
2
* A LogBox configuration data object
3
*/
4
component{
5
​
6
    function configure(){
7
        logBox={
8
​
9
        };
10
    }
11
}

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
1
logBox = {
2
    // Appenders
3
    appenders = {
4
        appenderName = {
5
            class="class.to.appender",
6
            layout="class.to.layout",
7
            levelMin=0,
8
            levelMax=4,
9
            properties={
10
                name  = value,
11
                prop2 = value 2
12
            }
13
    },
14
    // Root Logger
15
    root = { levelMin="FATAL", levelMax="DEBUG", appenders="*" },
16
    // Granualr Categories
17
    categories={
18
        "coldbox.system" = { levelMin="FATAL", levelMax="INFO", appenders="*" },
19
        "model.security" = { levelMax="DEBUG", appenders="console" }
20
    }
21
    // Implicit categories
22
    debug = [ "coldbox.system.interceptors"  ],
23
    info  = [ "model.class", "model2.class2" ],
24
    warn  = [ "model.class", "model2.class2" ],
25
    error = [ "model.class", "model2.class2" ],
26
    fatal = [ "model.class", "model2.class2" ],
27
    off   = [ "model.class", "model2.class2" ]
28
};

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:
1
init([CFCConfig,CFCConfigPath])
Copied!
CFCConfig : The object instance that has the logbox configuration data
CFCConfigPath : The instantiation path of the object that has the logbox configuration data
1
// Using config path
2
config = createObject( "component", "logbox.system.logging.config.LogBoxConfig" )
3
    .init( CFCConfigPath="my.path.LogBoxConfig" );
4
logBox = createObject( "component", "logbox.system.logging.LogBox" ).init( config );
5
​
6
// Using config object
7
data = createObject( "component", "my.data.CFC" );
8
config = createObject( "component", "logbox.system.logging.config.LogBoxConfig" ).init( data );
9
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.
