NAME

Handel::ConfigReader - Read in Handel configuration settings

SYNOPSIS

use Handel::ConfigReader;

my $cfg = Handel::ConfigReader-new();
my $setting = $cfg->get('HandelMaxQuantity');

DESCRIPTION

Handel::ConfigReader is a generic wrapper to get various configuration values. As some point this will probably get worked into XS/custom httpd.conf directives.

Starting in version 0.11, each instance is also a tied hash. The two usages are the same:

my $cfg = Handel::ConfigReader->new();

my $setting = $cfg->get('Setting');
my $setting = $cfg->{'Setting'};

Thie latter is the preferred usage in anticipation of als integrating Apache::ModuleConfig and custom directives which use the same hash syntax.

CONSTRUCTOR

new

Returns a new Handel::ConfigReader object.

my $cfg = Handel::ConfigReader->new();

METHODS

get($key [, $default])

Returns the configured value for the key specified. You can use this as an instance method or as a simpleton:

my $setting = Handel::ConfigReader->get('HandelMaxQuantity');

my $cfg = Handel::ConfigReader->new();
my $setting = $cfg->get('HandelMaxQuantity');

You can also pass a default value as the second parameter. If no value is loaded for the key specified, the default value will be returned instead.

CONFIGURATION

Various Handel runtime options can be set via %ENV variables, or using PerlSetVar when running under mod_perl.

HandelMaxQuantity

PerlSetVar  HandelMaxQuantity   32
...
$ENV{HandelMaxQuantity} = 32;

If defined, this sets the maximum quantity allowed for each Handel::Cart::Item in the shopping cart. By default, when the user request more than HandelMaxQuantity, quantity is reset to HandelMaxQuantity. If you would rather raise an Handel::Exception::Constraint instead, see HandelMaxQuantityAction below.

HandelMaxQuantityAction (Adjust|Exception)

This option defines what action should be taken when a cart items quantity is being set to something above HandelMaxQuantity. When set to Adjust the quantity qill simple be reset to HandelMaxQuantity and no exception will be raised. This is the default action.

When set to <Exception> and the quantity requested is greater than HandelMaxQuantity, a Handel::Exception::Constraint exception is thrown.

HandelCurrencyCode

This sets the default currency code used when no code is passed into format. See Locale::Currency::Format for all available currency codes. The default code is USD.

HandelCurrencyFormat

This sets the default options used to format the price. See Locale::Currency::Format for all available currency codes. The default format used is FMT_STANDARD. Just like in Locale::Currency::Format, you can combine options using |.

HandelDBIDriver

The name of the DBD driver. Defaults to mysql.

HandelDBIHost

The name of the database server. Defaults to localhost.

HandelDBIPort

The port of the database server. Defaults to 3306.

HandelDBIName

The name of the database. Defaults to commerce.

HandelDBIUser

The user name used to connect to the server. Defaults to commerce.

HandelDBIPassword

The password used to connect to the server. Defaults to commerce.

HandelPluginPaths

This resets the checkout plugin search path to a namespace of your choosing, The default plugin search path is Handel::Checkout::Plugin::*

PerlSetVar HandelPluginPaths MyApp::Plugins

In the example above, the checkout plugin search path will load all plugins in the MyApp::Plugins::* namespace (but not MyApp::Plugin itself). Any plugins in Handel::Checkout::Plugin::* will be ignored.

You can also pass a comma or space seperate list of namespaces.

PerlSetVar HandelPluginPaths 'MyApp::Plugins, OtherApp::Plugins'

Any plugin found in the search path that isn't a subclass of Handel::Checkout::Plugin will be ignored.

HandelAddPluginPaths

This adds an additional plugin search paths. This can be a comma or space seperated list of namespaces.

PerlSetVar HandelAddPluginPaths  'MyApp::Plugins, OtherApp::Plugins'

In the example above, when a checkout process is loaded, it will load all plugins in the Handel::Checkout::Plugin::*, MyApp::Plugins::*, and OtherApp::Plugins namespaces.
