Sympa::Message::Plugin(3Sympa)

NAME
Sympa::Message::Plugin - process hooks

SYNOPSIS
    Sympa::Message::Plugin::execute('post_archive', $message);

DESCRIPTION
Sympa::Message::Plugin provides hook mechanism to intervene in processing by Sympa. Each hook may modify objects (messages and so on) or may break ordinary processing.

Notice: Hook mechanism is experimental. Module names and interfaces may be changed in the future.

  Methods

execute ( HOOK_NAME, MESSAGE, [ KEY => VAL, ... ] )
    Process message hook.

  Hooks
Currently, following hooks are supported:

pre_distribute
    Message hook. Message had been approved distribution (by scenario or by moderator), however, it has not been decorated (adding custom subject etc.) nor archived yet.

post_archive
    Message hook. Message had been archived, however, it has not been distributed to users including digest spool; message has not been signed nor encrypted (if necessary).

  How to add a hook to your Sympa
First, write your hook module:

  package My::Hook;

  use constant gettext_id => 'My message hook';

  sub post_archive {
      my $module  = shift;    # module name: "My::Hook"
      my $name    = shift;    # handler name: "post_archive"
      my $message = shift;    # Message object
      my %options = @_;

      # Processing, possiblly changing $message...

      # Return suitable result.
      # If unrecoverable error occurred, you may return undef or simply die.
      return 1;
  }

  1;

Then activate hook handler in your list config:

  message_hook
    post_archive My::Hook
