NAME
Handel::ConfigReader - Read in Handel configuration settings
SYNOPSIS
use Handel::ConfigReader;
my $cfg = Handel::ConfigReader-new();
my $setting = $cfg->get('HandelMaxQuantity');VERSION
$Id: ConfigReader.pm 285 2005-03-04 02:29:22Z claco $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
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 |.
