perl-MooseX-Attribute-ENV


Set default of an attribute to a value from %ENV


Development/Libraries/Perl

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.
