Re^4: Dancer2 hook

Correct. Here you go:

package Dancer2::Plugin::TestHook
use Dancer2;
use Dancer2::Core::Error;

hook after_error => sub {
   my $content = shift;
   $content->{content} .= "hello world";
}

1;

This hook works fine, but it doesn't get called when I use the module (Dancer::Plugin::TestHook) somewhere else. That's the problem.

Still incomplete. Where is the app that triggers an error?	[reply]

Hi That doesn't compile Also, it is still incomplete Still, if I go ahead and fill in the blanks by copying `dancer2 -a HookTest` I think I see what you see You should read https://metacpan.org/pod/Dancer2::Plugin#Writing-the-plugin This triggers package TestHook; use Dancer2::Plugin; sub BUILD { my( $plugin ) = @_; $plugin->app->add_route( method => 'get', regexp => '/die', code => sub { die "get '/die' => sub { " }, ); $plugin->app->add_route( method => 'get', regexp => '/ride', code => sub { 'ride' }, ); $plugin->app->add_hook( Dancer2::Core::Hook->new( name => 'after_error', #~ code => sub { $_[0]->content( $_[0]->content . " ... please +?" ) } code => sub { my $content = shift; warn ' From TestHook From TestHook From TestHo +ok From TestHook From TestHook '; $content->{content} .= " hello world From TestHook + "; } )); } 1; __END__ [download]	[reply] [d/l] [select]
