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


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 the Data::Phrasebook manpage 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

the Data::Phrasebook::Loader::Text manpage inherits from the base class the Data::Phrasebook::Loader::Base manpage. 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 the Data::Phrasebook::Generic manpage'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.
