NAME

Config::Model::Backend::ShellVar - Read and write config as a SHELLVAR data structure

VERSION

version 2.145

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/}
   ],

  rw_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'.
