NAME

       Config::Model::FuseUI - Fuse virtual file interface for Config::Model

VERSION

       version 2.021

SYNOPSIS

	# command line
	mkdir fuse_dir
	config-edit -application popcon -ui fuse -fuse_dir fusedir
	ll fuse_dir
	fusermount -u fuse_dir

	# programmatic
	use Config::Model ;
	use Config::Model::FuseUI ;
	use Log::Log4perl qw(:easy) ;

	Log::Log4perl->easy_init($WARN);
	my $model = Config::Model -> new;
	my $root = $model -> instance (root_class_name => "PopCon") -> config_root ;
	my $ui = Config::Model::FuseUI->new( root => $root, mountpoint => "fuse_dir" );
	$ui -> run_loop ;  # blocking call

	# explore fuse_dir in another terminal then umount fuse_dir directory

DESCRIPTION

       This module provides a virtual file system interface for you configuration data. Each possible parameter of your configuration file is
       mapped to a file.

Example
	$ perl -Ilib config-edit -ui fuse -fuse_dir fused -appli popcon
	Mounting config on fused in background.
	Use command 'fusermount -u fused' to unmount
	$ ll fused

BUGS

       For some configuration, mapping each parameter to a file may lead to a high number of files.

constructor
new (...)
       parameters are:

       model
	   Config::Model object

       root
	   Root of the configuration tree ("Config::Model::Node" object )

       mountpoint

Methods
   run_loop( fork_in_loop => 1|0, debug => 1|0)
       Mount the file system either in the current process or fork a new process before mounting the file system.  In the former case, the call is
       blocking. In the latter, the call will return after forking a process that will perform the mount. Debug parameter is passed to Fuse system
       to get Fuse traces.

   fuse_mount
       Mount the fuse file system. This method will block until the file system is unmounted (with "fusermount -u mount_point" command)

NAME

       Config::Model::Backend::ShellVar - Read and write config as a "SHELLVAR" data structure

VERSION

       version 2.021

SYNOPSIS

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

	my $model = Config::Model->new;
	$model->create_config_class (
	   name    => "MyClass",
	   element => [
	       [qw/foo bar/] => {qw/type leaf value_type string/}
	   ],

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

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

	$root->load('foo=FOO1 bar=BAR1' );

	$inst->write_back ;

       File "foo.conf" now contains:

	## This file was written by Config::Model
	## You may modify the content of this file. Configuration
	## modifications will be preserved. Modifications in
	## comments may be mangled.
	##
	foo="FOO1"

	bar="BAR1"

DESCRIPTION

       This module is used directly by Config::Model to read or write the content of a configuration tree written with "SHELLVAR" 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 => 'shellvar' ) ;
       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.
