Hi Joshua,
I took out the call_hooks because it was a woefully underpowered abstraction.
I replaced with an amazing abstraction called Spoon::Hooks that allows you to
add pre/post hook methods to any method in Kwiki.
There are several plugins that already make use of this facility. Use them as
examples. To get started, just do something like this:
package KwikiEmailDiffThingy;
use Kwiki::Plugin -Base;
const class_id => 'kwiki_email_diff_thingy';
sub register {
my $r = shift;
$r->add(hook => 'page:store', pre => 'my_hook_sub');
}
sub my_hook_sub {
$self = $self->hub->kwiki_email_diff_thingy;
my $hook = pop;
...
# $hook->cancel; # if you want to stop the original call...
...
}
I think you'll agree that Spoon::Hooks gives you the power you need.
Cheers, Brian
