CGI::Application::Plugin::Phrasebook - A CGI::Application plugin for Data::Phrasebook

SYNOPSIS

Top

  package MyCGIApp;

  use base 'CGI::Application';
  use CGI::Application::Plugin::Phrasebook;

  sub cgiapp_prerun {
      my $self = shift;
      $self->config_phrasebook(
          class  => 'Plain',
          loader => 'YAML',
          file   => 'conf/my_phrasebook.yml',        
      ); 
      # ... do other stuff here ...
  }

  sub some_run_mode {
      my $self = shift;
      # grab the phrasebook instance 
      # and fetch a keyword from it
      return $self->phrasebook->fetch('a_phrasebook_keyword');
  }

DESCRIPTION

Top

This is a very simple plugin which provides access to an instance (or instances) of Data::Phrasebook inside your CGI::Application. I could have just stuffed this in with param, but this way is much nicer (and easier to type).

METHODS

Top

config_phrasebook (@phrasebook_args|\%multiple_phrasebooks)

Given an array of arguments, this configures your Data::Phrasebook instance by simply passing any arguments onto Data::Phrasebook::new. It then stashes it into the CGI::Application instance.

If given a HASH reference, this will configure multiple Data::Phrasebook instances, one for each hash key. Here is an example, of how that would be used.

  package MyCGIApp;

  use base 'CGI::Application';
  use CGI::Application::Plugin::Phrasebook;

  sub cgiapp_prerun {
      my $self = shift;
      $self->config_phrasebook({
          my_yaml_phrasebook => { 
              class  => 'Plain',
              loader => 'YAML',
              file   => 'conf/my_phrasebook.yml',        
          },
          my_txt_phrasebook => {
              class  => 'Plain',
              loader => 'Text',
              file   => 'conf/my_phrasebook.txt',            
          }
      }); 
      # ... do other stuff here ...
  }

  sub some_run_mode {
      my $self = shift;
      return $self->phrasebook('my_yaml_phrasebook')->fetch('a_phrasebook_keyword');
  }

  sub some_other_run_mode {
      my $self = shift;
      return $self->phrasebook('my_txt_phrasebook')->fetch('a_phrasebook_keyword');
  }

You can also assign one of the hash keys to the string __DEFAULT__, and it will be used as the default phrasebook. But this behavior is optional.

phrasebook (?$phrasebook_name)

This will return the Data::Phrasebook instance, or undef if one has not yet been configured.

If the plugin has been configured with multiple phrasebooks, you can specify the particular $phrasebook_name, if one is not specified, it will attempt to use the phrasebook called __DEFAULT__. If the phrasebook is not found, undef is returned.
