NAME

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

VERSION

       version 2.021

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).

NAME

       Config::Model::TreeSearcher - Search tree for match in value, description...

VERSION

       version 2.021

SYNOPSIS

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

	# define configuration tree object
	my $model = Config::Model->new ;
	$model ->create_config_class (
	   name => "MyClass",
	   element => [
	       [qw/foo bar/] => {
		   type => 'leaf',
		   value_type => 'string'
	       },
	       baz => {
		   type => 'hash',
		   index_type => 'string' ,
		   cargo => {
		       type => 'leaf',
		       value_type => 'string',
		   },
	       },

	   ],
	) ;

	my $inst = $model->instance(root_class_name => 'MyClass' );

	my $root = $inst->config_root ;

	my $step = 'baz:fr=bonjour baz:hr="dobar dan" foo="journalled"';
	$root->load( step => $step ) ;

	my @result = $root->tree_searcher(type => 'value')->search('jour');
	print join("
",@result),"
" ;
	# print
	#  baz:fr
	#  foo

DESCRIPTION

       This class provides a way to search the content of a configuration tree.  Given a keyword or a pattern, the search method will scan the
       tree to find a value, a description or anything that match the given pattern (or keyword).

Constructor
   new (type => [ value | description ... ] )
       Creates a new searcher object. The "type" parameter can be:

       element
       value
       key
       summary
       description
       help
       all Search in all the items above

Methods
   search(keyword)
       Search the keyword or pattern in the tree. The search is done in a case insensitive manner. Returns a list of path pointing to the matching
       tree element. See "grab(...)" in Config::Model::AnyThing for details on the path syntax.

BUGS

       Creating a class with just one search method may be overkill. OTOH, it may be extended later to provide iterative search.
