NAME MooseX::SimpleConfig - A Moose role for setting attributes from a simple configfile 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 configfiles to set object attributes. It is based on the abstract role MooseX::ConfigFromFile, and uses Config::Any to load your configfile. 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. Like all MooseX::ConfigFromFile -derived configfile loaders, this module is automatically supported by the MooseX::Getopt role as well, which allows specifying "-configfile" on the commandline. ATTRIBUTES configfile Provided by the base role MooseX::ConfigFromFile. You can provide a default configfile 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 configfile from which to load other attributes. Explicit arguments to "new_with_config" will override anything loaded from the configfile. get_config_from_file Called internally by either "new_with_config" or MooseX::Getopt's "new_with_options". Invokes Config::Any to parse "configfile". AUTHOR Brandon L.
