NAME
Config::Model::Backend::Dpkg - Read and write config as plain file
SYNOPSIS
use Config::Model;
use Log::Log4perl qw(:easy);
Log::Log4perl->easy_init($WARN);
my $model = Config::Model->new;
my $inst = $model->create_config_class(
name => "WithDpkg",
element => [
[qw/source new/] => { qw/type leaf value_type uniline/ },
],
read_config => [
{
backend => 'plain_file',
config_dir => '/tmp',
},
],
);
my $inst = $model->instance(root_class_name => 'WithDpkg' );
my $root = $inst->config_root ;
$root->load('source=foo new=yes' );
$inst->write_back ;
Now "/tmp" directory will contain 2 files: "source" and "new" with "foo" and "yes" inside.
DESCRIPTION
This module is used directly by Config::Model to read or write the content of a configuration tree written in several files. Each element of the node is written in a plain file.
This module supports currently only leaf and list elements. In the case of "list" element, each line of the file is a value of the list.
CONSTRUCTOR
new ( node => $node_obj, name => 'plain_file' ) ;
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.
