MooseX::SimpleConfig(3) A Moose role for setting attributes from a simple configuration file

VERSION

version 0.11

SYNOPSIS


## A YAML configfile named /etc/my_app.yaml:
foo: bar
baz: 123
## In your class
package My::App;
use Moose;
with 'MooseX::SimpleConfig';
has 'foo' => (is => 'ro', isa => 'Str', required => 1);
has 'baz' => (is => 'rw', isa => 'Int', required => 1);
# ... rest of the class here
## in your script
#!/usr/bin/perl
use My::App;
my $app = My::App->new_with_config(configfile => '/etc/my_app.yaml');
# ... rest of the script here
####################
###### combined with MooseX::Getopt:
## In your class
package My::App;
use Moose;
with 'MooseX::SimpleConfig';
with 'MooseX::Getopt';
has 'foo' => (is => 'ro', isa => 'Str', required => 1);
has 'baz' => (is => 'rw', isa => 'Int', required => 1);
# ... rest of the class here
## in your script
#!/usr/bin/perl
use My::App;
my $app = My::App->new_with_options();
# ... rest of the script here
## on the command line
% perl my_app_script.pl -configfile /etc/my_app.yaml -otherthing 123

DESCRIPTION

This role loads simple files to set object attributes. It is based on the abstract role MooseX::ConfigFromFile, and uses Config::Any to load your configuration file. Config::Any will in turn support any of a variety of different config formats, detected by the file extension. See Config::Any for more details about supported formats.

To pass additional arguments to Config::Any you must provide a "config_any_args()" method, for example: 

  sub config_any_args {
    return {
      driver_args => { General => { '-InterPolateVars' => 1 } }
    };
  }

Like all MooseX::ConfigFromFile -derived file loaders, this module is automatically supported by the MooseX::Getopt role as well, which allows specifying "-configfile" on the command line.

ATTRIBUTES

configfile

Provided by the base role MooseX::ConfigFromFile. You can provide a default configuration file pathname like so: 

  has '+configfile' => ( default => '/etc/myapp.yaml' );

You can pass an array of filenames if you want, but as usual the array has to be wrapped in a sub ref. 

  has '+configfile' => ( default => sub { [ '/etc/myapp.yaml', '/etc/myapp_local.yml' ] } );

Config files are trivially merged at the top level, with the right-hand files taking precedence.

CLASS METHODS

new_with_config

Provided by the base role MooseX::ConfigFromFile. Acts just like regular "new()", but also accepts an argument "configfile" to specify the file from which to load other attributes. Explicit arguments to "new_with_config" will override anything loaded from the file.

get_config_from_file

Called internally by either "new_with_config" or MooseX::Getopt's "new_with_options". Invokes Config::Any to parse "configfile".
