NAME

Wiki::Toolkit::Formatter::Multiple - Allows a Wiki::Toolkit wiki to use more than one formatter.

DESCRIPTION

A "dummy" formatter for Wiki::Toolkit. Passes methods through to other Wiki::Toolkit formatters, depending on supplied metadata.

SYNOPSIS

  use Wiki::Toolkit::Formatter::Multiple;
  use Wiki::Toolkit::Formatter::Pod;
  use Wiki::Toolkit::Formatter::UseMod;

  my $pod_fmtr = Wiki::Toolkit::Formatter::Pod->new(
      node_prefix => "wiki.cgi?node=",
  );

  my $usemod_fmtr = Wiki::Toolkit::Formatter::UseMod->new(
      node_prefix    => "wiki.cgi?node=",
      extended_links => 1,
      allowed_tags   => [ qw( p b i div br ) ],
  );

  my $formatter = Wiki::Toolkit::Formatter::Multiple->new(
      documentation => $pod_fmtr,
      discussion    => $usemod_fmtr,
      _DEFAULT      => $usemod_fmtr,
  );

  my $wiki = Wiki::Toolkit->new( store     => ...,
                                 formatter => $formatter );
  my $output = $wiki->format( "This is some discussion.",
                              { formatter => "discussion" } );
  

METHODS

new

  my $formatter = Wiki::Toolkit::Formatter::Multiple->new(
      label_1  => Formatter1->new( ... ),
      label_2  => Formatter2->new( ... ),
      _DEFAULT => Wiki::Toolkit::Formatter::Default->new,
  );

You may supply as many formatter objects as you wish. They don't have to be of different classes; you may just wish to, for example, permit different HTML tags to be used on different types of pages.

The "labels" supplied as the keys of the parameter hash should be unique. When you write a node, you should store a key-value pair in its metadata where the key is formatter and the value is the label of the formatter that should be used to render that node.

The _DEFAULT label is special - it defines the formatter that will be used for any node that does not have a formatter stored in its metadata. The _DEFAULT formatter, if not supplied to ->new, will default to the very basic Wiki::Toolkit::Formatter::Default.

format( $raw, \%metadata )

    my $output = $formatter->format( "Here is some text.", undef,
                                     { formatter => "discussion" } );

Uses the value of formatter given in the metadata to decide which of the formatter objects passed on instantiation to use, then uses it to format the provided rawwikitext.

The undef second element of the parameter array in the example is there because when this is called from a Wiki::Toolkit object, the wiki object passes itself in as the second parameter.
