Dancer2 hook

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Oh holy monks,

I have a question regarding Dancer2 and hooks. I would like use a specific hook from Dancer::Core::Error. It's the hook after_error. And what I am trying to do is have this hook applied to all errors in my application. But I want it applied from a module that I use. In other words, if the someone uses the module, then the hook gets applied to any errors.

Anyway, I can't seem to "export" the hook from the module to the application. I read the docs, but I am still can't get it to work. Any ideas?

We need a Short, Self-Contained, Correct Example here. What is the code you are using? I realize you posted this anonymously, so you will need to post the code that is not working in a reply. Maybe someone will be able to help you.	[reply]

Thanks for the reply. The hook works fine. But it's the implementation that I am having trouble with. By implementation, I mean, putting the hook in a module that I can then use when I want the hook to be applied to errors. So the code part is real simple: `hook after_error => sub { my $response = shift; };` [download] The problem is that this code is not catching errors from the application that uses the module. Get it?	[reply] [d/l]

That is not demonstrative self contained code	[reply]

Huh? Does this not work? `hook after_error => sub { my $response = shift; };` [download] https://metacpan.org/pod/Dancer2::Core::Hook	[reply] [d/l]

It doesn't work when I put it in a module that gets used. Do you understand? The hook works, yes. But it's the implementation that I am having trouble with.	[reply]
