NAME

Wiki::Toolkit::Plugin - A base class for Wiki::Toolkit plugins.

DESCRIPTION

Provides methods for accessing the backend store, search and formatter objects of the Wiki::Toolkit object that a plugin instance is registered with.

SYNOPSIS

  package Wiki::Toolkit::Plugin::Foo;
  use base qw( Wiki::Toolkit::Plugin);

  # And then in your script:
  my $wiki = Wiki::Toolkit->new( ... );
  my $plugin = Wiki::Toolkit::Plugin::Foo->new;
  $wiki->register_plugin( plugin => $plugin );
  my $node = $plugin->datastore->retrieve_node( "Home" );

POSSIBLE METHODS

pre_moderate

  Called before moderation is performed.
  Allows changes to the parameters used in moderation.

  my %args = @_;
  my ($name_ref,$version_ref) = @args{ qw( node version ) };
  $$name_ref =~ s/\s/_/g;
  return 0;

post_moderate

  Called after moderation has been performed.
  Allows additional actions to occur after node moderation.

  my %args = @_;
  my ($node,$node_id,$version) = 
     @args{ qw( node node_id version ) };
  &update_pending_list($node,$version);

pre_rename

  Called before a rename is performed.
  Allows changes to the parameters used by rename.

  my %args = @_;
  my ($old_name_ref,$new_name_ref,$create_new_versions_ref) = 
     @args{ qw( old_name new_name create_new_versions ) };
  $$old_name_ref =~ s/\s/_/g;
  $$new_name_ref =~ s/\s/_/g;
  return 0;

post_rename

  Called after a rename has been performed.
  Allows additional actions to occur after node renames.

  my %args = @_;
  my ($old_name,$new_name,$node_id) =
     @args{ qw( old_name new_name node_id ) };
  &recalculate_category_listings();

pre_retrieve

  Called before a retrieve is performed.
  Allows changes to the parameters used by retrieve.

  my %args = @_;
  my ($name_ref,$version_ref) = @args{ qw( node version ) };
  return &check_retrive_allowed($$name_ref);

  TODO: Allow declining of the read.

pre_write

  Called before a write is performed.
  Allows changes to the parameters used by the write;

  my %args = @_;
  my ($node_ref,$content_ref,$metadata_ref) = 
      @args{ qw( node content metadata ) };
  $$content_ref =~ s/\bpub\b/Pub/g;
  return 1;

post_write

  Called after a write has been performed.
  Allows additional actions to occur after node writes.

  my %args = @_;
  my ($node,$node_id,$version,$content,$metadata) =
     @args{ qw( node node_id version content metadata ) };
  &log_node_write($node,gmtime);

post_delete

  Called after a delete has been performed.
  Allows additional actions to occur after node deletions.

  my %args = @_;
  my ($node,$node_id,$version) = 
     @args{ qw( node node_id version ) };
  &log_node_delete($node,gmtime);

DECLINING ACTIONS FROM PRE_ METHODS

  Note: This functionality is missing for pre_retrieve

  It is possible for the pre_ methods (eg C<pre_write>) to
  decline the action. This could be due to an authentication
  check done by the plugin, due to the content, or whatever else
  the plugin fancies. There are three possible return values from
  a pre_ plugin:

  C<-1> - Deny this action
  C<0> or C<undef> - I have no opinion
  C<1> - Allow this action

  If you have only zeros, the action will be allowed. If you have ones
  and zeros, it will also be allowed.

  If you have minus ones and zeros, it will be denied. If you have minus
  ones, ones and zeros, the sum will be used to decide. 

  For default deny, have one plugin return -1, and another only return 1 
  if the action is explicity allowed)

METHODS

new

  sub new {
      my $class = shift;
      my $self = bless {}, $class;
      $self->_init if $self->can("_init");
      return $self;
  }

Generic contructor, just returns a blessed object.

wiki

Returns the Wiki::Toolkit object, or undef if the register_plugin method hasn't been called on a Wiki::Toolkit object yet.

datastore

Returns the backend store object, or undef if the register_plugin method hasn't been called on a Wiki::Toolkit object yet.

indexer

Returns the backend search object, or undef if the register_plugin method hasn't been called on a Wiki::Toolkit object yet, or if the wiki object had no search object defined.

formatter

Returns the backend formatter object, or undef if the register_plugin method hasn't been called on a Wiki::Toolkit object yet.
