Hi, I'm trying to have my Dancer Plugin FlashMessage work with Dancer2. However, this plugin tries to installs a hook on before_template_render. This doesn't work in Dancer2 because the 'hook' keyword does : $self->app->add_hook(...), so it adds the hook on the app instance. However this app instance only supports these hooks : qw/before after before_request after_request/ (see Dancer::Core::App::supported_hooks ). To be able to add a before_template_render, I should access to a template instance that consumes the Dancer::Core::Role::Template role. So, basically, the code of 'hook()' in Dancer::Core::DSL should call add_hook on the app, it should find out which instance the hook should be added to, and call add_hook on it. Now that brings up some questions. An easy way would be that there is a central point that lists all the possible hooks, and which instance (either the app, or the template engine) ->add_hook should be called upon. But that breaks the encapsulation (each role advertise which hooks it supports). And loading every engines to find out which one supports a given hook seems a bit heavy to me, and prevent the "load only when needed" practice. So, any idea ?
