Data::Phrasebook::Loader::Text(3)

NAME
Data::Phrasebook::Loader::Text - Absract your phrases with plain text files.

SYNOPSIS
    use Data::Phrasebook;

    my $q = Data::Phrasebook->new(
        class  => 'Fnerk',
        loader => 'Text',
        file   => 'phrases.txt',
    );

    # use default delimiters (:variable)
    my $phrase = $q->fetch($keyword,{variable => 'substitute'});

    # use Template Toolkit style delimiters
    $q->delimiters( qr{ \[% \s* (\w+) \s* %\] }x );
    my $phrase = $q->fetch($keyword,{variable => 'substitute'});

DESCRIPTION
This loader plugin implements phrasebook patterns using plain text files.

Phrases can be contained within one or more dictionaries, with each phrase accessible via a unique key. Phrases may contain placeholders, please see Data::Phrasebook for an explanation of how to use these. Groups of phrases are kept in a dictionary. In this implementation a single file is one complete dictionary.

An example plain text file:

  foo=Welcome to :my world. It is a nice :place.

Within the phrase text placeholders can be used, which are then replaced with the appropriate values once the get() method is called. The default style of placeholders can be altered using the delimiters() method.

INHERITANCE
Data::Phrasebook::Loader::Text inherits from the base class Data::Phrasebook::Loader::Base. See that module for other available methods and documentation.

METHODS

  load
Given a "file", load it. "file" must contain a valid phrase map.

   my $file = 'english.txt';
   $loader->load( $file );

This method is used internally by Data::Phrasebook::Generic's "data" method, to initialise the data store.

To utilise the dictionary framework for a Plain Text phrasebook, the idea is to use a directory of files, where the directory is passed via the "file" argument and the dictionary, the specific name of the file, is passed via the "dictionary" argument.

   my $file = '/tmp/phrasebooks';
   my $dictionary = 'english.txt';
   $loader->load( $file, $dictionary );

  get
Returns the phrase stored in the phrasebook, for a given keyword.

   my $value = $loader->get( $key );

  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 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 "file" and "dict" attributes as required, the object can return a list of the current keywords available as:

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

  my @keywords = $pb->keywords;

or

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

Note that $path can either be the directory path, where $dict must be the specific file name of the dictionary, or the full path of the dictionary file.

In the second instance, the function will not load a dictionary, but can be used to interrogate the contents of a known dictionary.
