VERSION

version 2.017

SYNOPSIS

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

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

    element => [ 

        [qw/foo bar/] => {
            type       => 'leaf',
            value_type => 'string'
        },
        hash_of_nodes => {
            type       => 'hash',     # hash id
            index_type => 'string',
            cargo      => {
                type              => 'node',
                config_class_name => 'Foo'
            },
        },
    ],
 ) ;

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

 my $root = $inst->config_root ;

 # put data
 my $step = 'foo=FOO hash_of_nodes:fr foo=bonjour -
   hash_of_nodes:en foo=hello ';
 $root->load( step => $step );

 my $ui = Config::Model::SimpleUI->new( root => $root ,
                                        title => 'My class ui',
                                        prompt => 'class ui',
                                      );

 # engage in user interaction
 $ui -> run_loop ;

 print $root->dump_tree ;

Once the synopsis above has been saved in my_test.pl, you can do:

 $ perl my_test.pl
 class ui:$ ls
 foo  bar  hash_of_nodes
 class ui:$ ll hash_of_nodes
 name         value        type         comment                            
 hash_of_nodes <Foo>        node hash    keys: "en" "fr"                    
 
 class ui:$ cd hash_of_nodes:en
 
 class ui: hash_of_nodes:en $ ll
 name         value        type         comment                            
 foo          hello        string                                          
 bar          [undef]      string                                          
 
 class ui: hash_of_nodes:en $ set bar=bonjour
 
 class ui: hash_of_nodes:en $  ll
 name         value        type         comment                            
 foo          hello        string                                          
 bar          bonjour      string                                          
 
 class ui: hash_of_nodes:en $ ^D

At the end, the test script will dump the configuration tree. The modified bar value can be found in there:

 foo=FOO
 hash_of_nodes:en
   foo=hello
   bar=bonjour -
 hash_of_nodes:fr
   foo=bonjour - -
