SYNOPSIS

use Config::Model;
my $model = Config::Model->new;
$model->create_config_class (
name => "MyClass",
element => [
[qw/foo bar/] => {qw/type leaf value_type string/}
],
read_config => [
{
backend => 'ShellVar',
config_dir => '/tmp',
file => 'foo.conf',
auto_create => 1,
}
],
);
my $inst = $model->instance(root_class_name => 'MyClass' );
my $root = $inst->config_root ;
$root->load('foo=FOO1 bar=BAR1' );
$inst->write_back ;

File "foo.conf" now contains:

 ## This file was written by Config::Model
 ## You may modify the content of this file. Configuration 
 ## modifications will be preserved. Modifications in
 ## comments may be mangled.
 ##
 foo="FOO1"
 bar="BAR1"

DESCRIPTION

This module is used directly by Config::Model to read or write the content of a configuration tree written with "SHELLVAR" syntax in "Config::Model" configuration tree.

Note that undefined values are skipped for list element. I.e. if a list element contains "('a',undef,'b')", the data structure contains 'a','b'.

CONSTRUCTOR

new ( node => $node_obj, name => 'shellvar' ) ;

Inherited from Config::Model::Backend::Any. The constructor is called by Config::Model::BackendMgr.

read ( io_handle => ... )

Of all parameters passed to this read call-back, only "io_handle" is used. This parameter must be IO::File object already opened for read.

It can also be undef. In which case "read()" returns 0.

When a file is read, "read()" returns 1.

write ( io_handle => ... )

Of all parameters passed to this write call-back, only "io_handle" is used. This parameter must be IO::File object already opened for write.

"write()" returns 1.
