Config::Model::SimpleUI

NAME

Config::Model::SimpleUI - Simple interface for Config::Model

VERSION

version 2.152

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 ...

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 ... ]

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 [path]

Show configuration tree from current node or of a node pointed by path.

info [path]

Show debug information on current node or on the element pointed by path. The debug information may show model parametersm default or computed values.

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
