Config::Model::Itself 1.208 (Default branch)
Image Config::Model::Itself provides a configuration model for Config::Model. In other words, the structure of a model specification is described in Config::Model::Itself so you can use the same user interface to edit configuration data (for instance Xorg configuration data from xorg.conf) and Xorg model (if you need to add new parameters in Xorg model). You can also create your own configuration model to get a configuration tool for your own application. License: GNU Lesser General Public License (LGPL) Changes:
The allow_empty parameter was added. This way, a model designer can specify whether configuration can be created from scratch or not. In some cases (e.g. OpenSSH), creating a configuration from scratch should not be allowed because directories and files may require specific permissions. Minor corrections related to Augeas integration were made. Image

Config::Model::Annotation(3pm)				User Contributed Perl Documentation			    Config::Model::Annotation(3pm)

NAME

       Config::Model::Annotation - Read and write configuration annotations

VERSION

       version 2.021

SYNOPSIS

	use Config::Model ;
	use Log::Log4perl qw(:easy) ;
	Log::Log4perl->easy_init($WARN);

	# define configuration tree object
	my $model = Config::Model->new ;
	$model ->create_config_class (
	   name => "MyClass",
	   element => [
	       [qw/foo bar/] => {
		   type => 'leaf',
		   value_type => 'string'
	       },
	       baz => {
		   type => 'hash',
		   index_type => 'string' ,
		   cargo => {
		       type => 'leaf',
		       value_type => 'string',
		   },
	       },

	   ],
	) ;

	my $inst = $model->instance(root_class_name => 'MyClass' );

	my $root = $inst->config_root ;

	# put some data in config tree the hard way
	$root->fetch_element('foo')->store('yada') ;
	$root->fetch_element('baz')->fetch_with_id('en')->store('hello') ;

	# put annotation the hard way
	$root->fetch_element('foo')->annotation('english') ;
	$root->fetch_element('baz')->fetch_with_id('en')->annotation('also english') ;

	# put more data the easy way
	my $step = 'baz:fr=bonjour#french baz:hr="dobar dan"#croatian';
	$root->load( step => $step ) ;

	# dump resulting tree with annotations
	print $root->dump_tree;

	# save annotations
	my $annotate_saver = Config::Model::Annotation
	 -> new (
		 config_class_name => 'MyClass',
		 instance => $inst ,
		 root_dir => '/tmp/', # for test
		) ;
	$annotate_saver->save ;

	# now check content of /tmp/config-model/MyClass-note.pl

DESCRIPTION

       This module provides an object that read and write annotations (a bit like comments) to and from a configuration tree and save them in a
       file (not configuration file)

       Depending on the effective id of the process, the annotation will be saved in:

       o   "/var/lib/config-model/<model_name>-note.yml" for root (EUID == 0)

       o   "~/.config-model/<model_name>-note.yml" for normal user (EUID > 0)

CONSTRUCTOR

       Quite standard. The constructor is passed a Config::Model::Instance object.

METHODS

   save()
       Save annotations in a file (See DESCRIPTION)

   load()
       Loads annotations from a file (See DESCRIPTION)
