NAME

Config::Model::Backend::PlainFile - Read and write config as plain file

VERSION

version 2.046

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 => "WithPlainFile",
    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 => 'WithPlainFile' );
 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.

Methods

read_leaf (obj,elt,check,file,args);

Called by read method to read the file of a leaf element. args contains the arguments passed to read method.

read_hash (obj,elt,check,file,args);

Like read_leaf for hash elements.

read_list (obj,elt,check,file,args);

Like read_leaf for list elements.

write ( )

write() will write a file for each element of the calling class. Works only for leaf and list elements. Other element type are skipped. Always return 1 (unless it died before).
