NAME

MouseX::SimpleConfig - A Mouse role for setting attributes from a simple configfile

VERSION

version 0.11

SYNOPSIS

  ## A YAML configfile named /etc/my_app.yaml:
  foo: bar
  baz: 123
  ## In your class
  package My::App;
  use Mouse;
  with 'MouseX::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 MouseX::Getopt:
  ## In your class
  package My::App;
  use Mouse;
  with 'MouseX::SimpleConfig';
  with 'MouseX::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 MouseX::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 MouseX::ConfigFromFile -derived configfile loaders, this module is automatically supported by the MouseX::Getopt role as well, which allows specifying "-configfile" on the commandline.

ATTRIBUTES

configfile

Provided by the base role MouseX::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.

METHODS

new_with_config

Class method provided by the base role MouseX::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

Class method called internally by either "new_with_config" or MouseX::Getopt's "new_with_options". Invokes Config::Any to parse "configfile".
