NAME

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

VERSION

       version 2.047

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).
