Config::Model::TermUI(3) Interactive command line interface for cme

VERSION

version 2.087

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 "my_test.pl", you can achieve the same interactions as with "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 "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 helper to construct pure ASCII user interface on top of Term::ReadLine. To get better interaction you must install either Term::ReadLine::Gnu or Term::ReadLine::Perl.

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

Dependencies

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

USER COMMAND SYNTAX

See ``USER COMMAND SYNTAX'' in Config::Model::SimpleUI.

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).

BUGS

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