SYNOPSIS

12        use Config::Model;
13        use Config::Model::TermUI ;
14
15        # define configuration tree object
16        my $model = Config::Model->new;
17         $model->create_config_class(
18           name    => "Foo",
19           element => [
20               [qw/foo bar/] => {
21                   type       => 'leaf',
22                   value_type => 'string'
23               },
24           ]
25        );
26        $model ->create_config_class (
27           name => "MyClass",
28
29           element => [
30
31               [qw/foo bar/] => {
32                   type       => 'leaf',
33                   value_type => 'string'
34               },
35               hash_of_nodes => {
36                   type       => 'hash',     # hash id
37                   index_type => 'string',
38                   cargo      => {
39                       type              => 'node',
40                       config_class_name => 'Foo'
41                   },
42               },
43           ],
44        ) ;
45
46        my $inst = $model->instance(root_class_name => 'MyClass' );
47
48        my $root = $inst->config_root ;
49
50        # put data
51        my $steps = 'foo=FOO hash_of_nodes:fr foo=bonjour -
52          hash_of_nodes:en foo=hello ';
53        $root->load( steps => $steps );
54
55        my $ui = Config::Model::TermUI->new(
56            root => $root ,
57            title => 'My class ui',
58            prompt => 'class ui',
59        );
60
61        # engage in user interaction
62        $ui -> run_loop ;
63
64        print $root->dump_tree ;
65
66       Once the synopsis above has been saved in "my_test.pl", you can achieve
67       the same interactions as with "Config::Model::SimpleUI". Except that
68       you can use TAB completion:
69
70        class ui:$ ls
71        foo  bar  hash_of_nodes
72        class ui:$ ll hash_of_nodes
73        name         value        type         comment
74        hash_of_nodes <Foo>        node hash    keys: "en" "fr"
75
76        class ui:$ cd hash_of_nodes:en
77        class ui: hash_of_nodes:en $ ll
78        name         value        type         comment
79        foo          hello        string
80        bar          [undef]      string
81
82        class ui: hash_of_nodes:en $ set bar=bonjour
83        class ui: hash_of_nodes:en $ ll
84        name         value        type         comment
85        foo          hello        string
86        bar          bonjour      string
87
88        class ui: hash_of_nodes:en $ ^D
89
90       At the end, the test script dumps the configuration tree. The modified
91       "bar" value can be found in there:
92
93        foo=FOO
94        hash_of_nodes:en
95          foo=hello
96          bar=bonjour -
97        hash_of_nodes:fr
98          foo=bonjour - -

DESCRIPTION

101       This module provides a helper to construct pure ASCII user interface on
102       top of Term::ReadLine. To get better interaction you must install
103       either Term::ReadLine::Gnu or Term::ReadLine::Perl.
104
105       Depending on your installation, either Term::ReadLine::Gnu or
106       Term::ReadLine::Perl is used. See Term::ReadLine to override default
107       choice.
108

Dependencies

110       This module is optional and depends on Term::ReadLine to work. To
111       reduce the dependency list of Config::Model, "Term::ReadLine" is only
112       recommended. cme gracefully degrades to Config::Model::SimpleUI when
113       necessary.
114

USER COMMAND SYNTAX

116       See "USER COMMAND SYNTAX" in Config::Model::SimpleUI.
117

CONSTRUCTOR

119   parameters
120       root
121           Root node of the configuration tree
122
123       title
124           UI title
125
126       prompt
127           UI prompt. The prompt will be completed with the location of the
128           current node.
129

Methods

131   run_loop
132       Engage in user interaction until user enters '^D' (CTRL-D).
133

BUGS

135       ·   Auto-completion is not complete.
136
137       ·   Auto-completion provides wrong choice when you try to "cd" in a
138           hash where the index contains a white space. I.e. the correct
139           command is "cd foo:"a b"" instead of "cd foo: "a b"" as proposed by
140           auto completion.
