Config::Model::Backend::PlainFile(3) Read and write config as plain file


version 2.087


use Config::Model;
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 contains 2 files: "source" and "new" with "foo" and "yes" inside.


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.


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()" writes 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).
