SYNOPSIS

 use Config::Model;
 use Config::Model::SimpleUI ;

 # 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 $steps = 'foo=FOO hash_of_nodes:fr foo=bonjour -
   hash_of_nodes:en foo=hello ';
 $root->load( steps => $steps );

 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 dumps 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 - -

DESCRIPTION

USER COMMAND SYNTAX

cd ...

Jump into node or value element. You can use "cd <element>", "cd <elt:key>" or "cd -" to go up one node or "cd !" to go to configuration root.

clear elt

delete elt

Delete leaf value.

delete elt:key

Delete a list or hash element

display node_name elt:key

Display a value

ls [path] [ pattern ]

Show elements of current node or of a node pointed by path. Elements can be filtered with a shell pattern. See inline help for more details.

ll [-nz] [-v] [ pattern ... ]
