| Summary : Set default of an attribute to a value from %ENV
|
Description :
This is a Moose attribute trait that you use when you want the default
value for an attribute to be populated from the %ENV hash. So, for example
if you have set the environment variable USERNAME = \'John\' you can do:
package MyApp::MyClass;
use Moose;
use MooseX::Attribute::ENV;
has \'username\' => (is=>\'ro\', traits=>[\'ENV\']);
package main;
my $myclass = MyApp::MyClass->new();
print $myclass->username; # STDOUT => \'John\';
This is basically similar functionality to something like:
has \'attr\' => (
is=>\'ro\',
default=> sub {
$ENV{uc \'attr\'};
},
);
but this module has a few other features that offer merit, as well as being
a simple enough attribute trait that I hope it can serve as a learning
tool.
If the named key isn\'t found in %ENV, then defaults will execute as normal.
