version 2.031

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:

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

• ~/.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)
