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.

NAME

       Config::Model::Backend::Yaml - Read and write config as a YAML data structure

VERSION

       version 2.021

SYNOPSIS

	use Config::Model ;
	use Log::Log4perl qw(:easy) ;
	use Data::Dumper ;

	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',
		   },
	       },
	   ],
	 read_config  => [
			   { backend => 'yaml' ,
			     config_dir => '/tmp',
			     file  => 'foo.yml',
			     auto_create => 1,
			   }
			 ],
	) ;

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

	my $root = $inst->config_root ;

	my $step = 'foo=yada bar="bla bla" baz:en=hello
		    baz:fr=bonjour baz:hr="dobar dan"';
	$root->load( step => $step ) ;
	$inst->write_back ;

       Now, "/tmp/foo.yml" contains:

	---
	bar: bla bla
	baz:
	  en: hello
	  fr: bonjour
	  hr: dobar dan
	foo: yada

DESCRIPTION

       This module is used directly by Config::Model to read or write the content of a configuration tree written with YAML syntax in
       "Config::Model" configuration tree.

       Note that undefined values are skipped for list element. I.e. if a list element contains "('a',undef,'b')", the data structure will contain
       'a','b'.

CONSTRUCTOR

   new ( node => $node_obj, name => 'yaml' ) ;
       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.
