NAME
Config::Role - Moose config attribute loaded from file in home dir
VERSION
version 0.0.1
SYNOPSIS
package My::Class;
use Moose;
# Read configuration from ~/.my_class.ini, available in $self->config
has 'config_filename' => ( is => 'ro', isa => 'Str', lazy_build => 1 );
sub _build_config_filename { '.my_class.ini' }
with 'Config::Role';
# Fetch a value from the configuration, allow constructor override
has 'username' => ( is => 'ro', isa => 'Str', lazy_build => 1 );
sub _build_username { return (shift)->config->{'username'}; }
sub make_request {
my ($self) = @_;
my $response = My::Class::Request->make(
username => $self->username,
...
);
...
}
DESCRIPTION
Config::Role is a very basic role you can add to your Moose class that
allows it to take configuration data from a file located in your home
directory instead of always requiring parameters to be specified in the
constructor.
The synopsis shows how you can read the value of "username" from the
file ".my_class.ini" located in the home directory of the current user.
The location of the file is determined by whatever
"File::HomeDir->my_data" returns for your particular platform.
The config file is loaded by using Config::Any's "load_files()" method.
It will load the files specified in the "config_files" attribute. By
default this is an array reference that contains the filename from the
"config_file" attribute. If you specify multiple files which both
contain the same configuration key, the value is loaded from the first
file. That is, the most significant file should be first in the array.
The "Config::Any->load_files()" flag "use_ext" is set to a true value,
so you can use any configuration file format supported by Config::Any by
just specifying the common filename extension for the format.
ATTRIBUTES

A hash reference that holds the compiled configuration read from the
