=head1 NAME

Config::Model::TermUI - Interactive command line interface for cme

=head1 VERSION

version 2.117

=head1 SYNOPSIS

 use Config::Model;
 use Config::Model::TermUI ;

 # 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::TermUI->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 C<my_test.pl>, you can achieve the
same interactions as with C<Config::Model::SimpleUI>. Except that you can use
TAB completion:

 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
C<bar> value can be found in there:

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

=head1 DESCRIPTION

This module provides a helper to construct pure ASCII user interface
on top of L<Term::ReadLine>. To get better interaction you must
install either L<Term::ReadLine::Gnu> or L<Term::ReadLine::Perl>.

Depending on your installation, either L<Term::ReadLine::Gnu> or
L<Term::ReadLine::Perl> is used. See L<Term::ReadLine> to
override default choice.

=head1 Dependencies

This module is optional and depends on L<Term::ReadLine> to work. To
reduce the dependency list of L<Config::Model>, C<Term::ReadLine> is
only recommended. L<cme> gracefully degrades to
L<Config::Model::SimpleUI> when necessary.

=head1 USER COMMAND SYNTAX

See L<Config::Model::SimpleUI/"USER COMMAND SYNTAX">.

=head1 CONSTRUCTOR

=head2 parameters

=over

=item root

Root node of the configuration tree

=item title

UI title

=item prompt

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

=back

=head1 Methods

=head2 run_loop()

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

=head1 BUGS

=over

=item *

Auto-completion is not complete.

=item *

Auto-completion provides wrong choice when you try to C<cd> in a hash
where the index contains a white space. I.e. the correct command is
C<cd foo:"a b"> instead of C<cd foo: "a b"> as proposed by auto
completion.
