Config::Model::Itself 0.102 (Default branch)
Image Config::Model::Itself provides a configuration model for Config::Model. In other words, the structure of a model specification is described in Config::Model::Itself so you can use the same user interface to edit configuration data (for instance Xorg configuration data from xorg.conf) and Xorg model (if you need to add new parameters in Xorg model). You can also create your own configuration model to get a configuration tool for your own application. License: GNU Lesser General Public License (LGPL) Changes:
This release adds a graphical interface to config-model-edit, so you can update configuration models (like Xorg) with a graphical interface instead of editing the Perl data structure.Image

Config::Model::Backend::ShellVar(3pm)			User Contributed Perl Documentation		     Config::Model::Backend::ShellVar(3pm)

NAME

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

VERSION

       version 2.021

SYNOPSIS

	use Config::Model;
	use Log::Log4perl qw(:easy);
	Log::Log4perl->easy_init($WARN);

	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 will contain
       'a','b'.

CONSTRUCTOR

   new ( node => $node_obj, name => 'shellvar' ) ;
       Inherited from Config::Model::Backend::Any. The constructor will be called by Config::Model::AutoRead.

   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 this case, "read()" will return 0.

       When a file is read,  "read()" will return 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()" will return 1.
