NAME

       Data::Phrasebook::Generic - Base class for Phrasebook Models

SYNOPSIS

           use Data::Phrasebook;

           my $q = Data::Phrasebook->new(
               class  => 'Fnerk',
               loader => 'XML',
               file   => 'phrases.xml',
               dict   => 'English',
           );

DESCRIPTION

       This module provides a base class for phrasebook implementations.

CONSTRUCTOR

   new
       "new" takes an optional hash of arguments. Each value in the hash is given as an argument
       to a method of the same name as the key.

       This constructor should never need to be called directly as Phrasebook creation should go
       through the Data::Phrasebook factory.

       Subclasses should provide at least an accessor method to retrieve values for a named key.
       Further methods can be overloaded, but must retain a standard API to the overloaded
       method.

       All, or at least most, phrasebook implementations should inherit from this class.

METHODS

   loader
       Set, or get, the loader class. Uses a default if none have been specified. See
       Data::Phrasebook::Loader.

   unload
       Called by the file() and dict() methods when a fresh file or dictionary is specified, and
       reloading is required.

   loaded
       Accessor to determine whether the current dictionary has been loaded

   file
       A description of a file that is passed to the loader. In most cases, this is a file. A
       loader that gets its data from a database could conceivably have this as a hash like thus:

          $q->file( {
              dsn => "dbi:SQLite:dbname=bookdb",
              table => 'phrases',
          } );

       That is, which loader you use determines what your "file" looks like.

       The default loader takes just an ordinary filename.

   dict
       Accessor to store the dictionary to be used.

   dicts
       Having instantiated the "Data::Phrasebook" object class, and using the "file" attribute as
       a directory path, the object can return a list of the current dictionaries available
       (provided the plugin supports it) as:

         my $pb = Data::Phrasebook->new(
           loader => 'Text',
           file   => '/tmp/phrasebooks',
         );

         my @dicts = $pb->dicts;

       or

         my @dicts = $pb->dicts( $path );

   keywords
       Having instantiated the "Data::Phrasebook" object class, using the "dict" attribute as
       required, the object can return a list of the current keywords available (provided the
       plugin supports it) as:

         my $pb = Data::Phrasebook->new(
           loader => 'Text',
           file   => '/tmp/phrasebooks',
           dict   => 'TEST',
         );

         my @keywords = $pb->keywords;

       or

         my @keywords = $pb->keywords( $dict );

       Note the list will be a combination of the default and any named dictionary.  However, not
       all Loader plugins may support the second usage.

   data
       Loads the data source, if not already loaded, and returns the data block associated with
       the given key.

           my $data = $self->data($key);

       This is typically only used internally by implementations, not the end user.

   delimiters
       Returns or sets the current delimiters for substitution variables. Must be a regular
       expression with at least one capture group.

       The example below shows the default ':variable' style regex.

          $q->delimiters( qr{ :(\w+) }x );

       The example below shows a Template Toolkit style regex.

          $q->delimiters( qr{ \[% \s* (\w+) \s* %\] }x );

       In addition to the delimiter pattern, an optional setting to suppress missing value errors
       can be passed after the pattern. If set to a true value, will turn any unmatched delimiter
       patterns to an empty string.
