NAME
Config::Model::Backend::Debian::Dpkg - 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 => "WithDebian::Dpkg", 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 => 'WithDebian::Dpkg' ); 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. CONSTRUCTOR
new ( node => $node_obj, name => 'plain_file' ) ; 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. AUTHOR

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
