NAME

VERSION

SYNOPSIS

12        # Itself constructor returns an object to read or write the data
13        # structure containing the model to be edited
14        my $meta_model = Config::Model::Itself -> new( ) ;
15
16        # now load the model to be edited
17        $meta_model -> read_all( ) ;
18
19        # For Curses UI prepare a call-back to write model
20        my $wr_back = sub { $meta_model->write_all(); }
21
22        # create Curses user interface
23        my $dialog = Config::Model::CursesUI-> new (
24             store => $wr_back,
25        ) ;
26
27        # start Curses dialog to edit the mode
28        $dialog->start( $meta_model->config_root )  ;
29
30        # that's it. When user quits curses interface, Curses will call
31        # $wr_back sub ref to write the modified model.

DESCRIPTION

34       Config::Itself module and its model files provide a model of
35       Config:Model (hence the Itself name).
36
37       Let's step back a little to explain. Any configuration data is, in
38       essence, structured data. A configuration model is a way to describe
39       the structure and relation of all items of a configuration data set.
40
41       This configuration model is also expressed as structured data. This
42       structure data follows a set of rules which are described for humans in
43       Config::Model.
44
45       The structure and rules documented in Config::Model are also expressed
46       in a model in the files provided with "Config::Model::Itself".
47
48       Hence the possibity to verify, modify configuration data provided by
49       Config::Model can also be applied on configuration models. Using the
50       same user interface.
51
52       From a Perl point of view, Config::Model::Itself provides a class
53       dedicated to read and write a set of model files.
54

Constructor

56   new ( [ cm_lib_dir => ... ] )
57       Creates a new read/write handler. If no model_object is passed, the
58       required objects are created. "cm_lib_dir" specifies where are the
59       model files (defaults to "./lib/Config/Model".
60
61       "cm_lib_dir" is either a "Path::Tiny" object or a string.
62
63       By default, this constructor will create all necessary "Config::Model*"
64       objects.  If needed, you can pass already created object with options
65       "config_model" (Config::Model object), "meta_instance"
66       (Config::Model::Instance object) or "meta_root" (Config::Model::Node
67       object).
68
69   Methods

read_all ( [ root_model => ... ], [ force_load => 1 ] )

71       Load all the model files contained in "model_dir" and all its
72       subdirectories. "root_model" is used to filter the classes read.
73
74       Use "force_load" if you are trying to load a model containing errors.
75
76       "read_all" returns a hash ref containing ( class_name => file_name ,
77       ...)
78
79   write_all
80       Will write back configuration model in the specified directory. The
81       structure of the read directory is respected.
82
83   write_model_plugin( plugin_dir => foo, plugin_name => bar )
84       Write plugin models in the  passed "plugin_dir" directory. The written
85       file is path is made of plugin name and class names. E.g. a plugin
86       named "bar" for class "Foo::Bar" is written in "bar/Foo/Bar.pl" file.
87       This file is to be used by augment_config_class '...', class_data )">
88
89   read_model_plugin( plugin_dir => foo, plugin_name => bar.pl )
90       This method searched recursively "$plugin_dir/$plugin_name" and load
91       all "*.pl" files found there.
92
93   list_class_element
94       Returns a string listing all the class and elements. Useful for
95       debugging your configuration model.
96
97   get_dot_diagram
98       Returns a graphviz dot file that represents the structure of the
99       configuration model:
100
101       •   "include" relations are represented by solid lines
102
103       •   Class usage (i.e. "config_class_name" parameter) is represented by
104           dashed lines. The name of the element is attached to the dashed
105           line.
106

BUGS

108       Test menu entries are created from the content of "application" model
109       parameter.  Unfortunately, there's no way to build the menu
110       dynamically. So user cme must be restarted to change the menu if the
111       application list is changed.
