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

       This module provides a pure ASCII user interface using STDIN and STDOUT.

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.

       set elt=value
           Set a leaf value.

       set elt:key=value
           Set a leaf value locate in a hash or list element.

       clear elt
           Clear leaf value (set to "undef") or removed all elements of hash or list.

       delete elt
           Delete leaf value.

       delete elt:key
           Delete a list or hash element

       display node_name elt:key
           Display a value

       ls [ pattern ]
           Show elements of current node. Can be used with a shell pattern.

       ll [-nz] [-v] [ pattern ... ]
           Describe elements of current node. Can be used with shell patterns or element names.
           Skip empty element with "-nz" option. Display more information with "-v" option

       tree
           Show configuration tree from current node.

       help
           Show available commands.

       desc[ription]
           Show class description of current node.

       desc(elt)
           Show description of element from current node.

       desc(value)
           Show effect of value (for enum)

       changes
           Show unsaved changes

       check
           Without parameter, show warnings starting from current node. With an element name as
           parameter, do the same on the element.

       fix Try to fix warning starting from current node. With an element name as parameter, do
           the same on the element. With ""!"" as parameter, try to fix warnings starting from
           root node by calling apply_fixes there.

       exit
           Exit shell

CONSTRUCTOR

   parameters
       root
           Root node of the configuration tree

       title
           UI title

       prompt
           UI prompt. The prompt will be completed with the location of the current node.

Methods

   run_loop()
       Engage in user interaction until user enters '^D' (CTRL-D).
