[dancer-users] Again: Scope of 'hook before'

[Rick Westerman]

Still looking for an answer as to the scope of a 'hook before'. Does it 
affect all of the routes or just the routes within a 'prefix'.   My 
understanding is that Dancer2 does away with the globals found in Dancer 
thus I would expect that a 'hook before' within a 'prefix' would remain 
within the scope of the 'prefix' and not flow outside of it into the 
other routes.  But this is not what I find thus I am curious as to if I 
am doing something wrong or have my concept wrong.

Thanks,

Hello.  New Dancer2 user here.  I am having problems with the scope of a 
'hook before' while using 'prefix'.  I am not sure if I am doing 
something dumb or if this is simply not possible or something else is 
going on.

Using the prefix example from the Cookbook I have two modules

package myapp;
use Dancer2;
use myapp::admin;

prefix undef;
get '/' => sub { return 'main ' . dancer_version };
1;

And

package myapp::admin;
use Dancer2 appname => 'myapp';

prefix '/admin';

hook 'before' => sub {
     if (dancer_app->environment ne 'rick') {
         return halt;
     }
};

get '/' => sub { return 'admin' };
1;

As expected when running with environment 'rick' then the following 
output is produced:

/        ==> main 0.166001
/admin/  ==> admin

But, unexpectedly to me, using the default 'development' environment has 
the app just halting as it, I presume, hits the 'hook before'.    I 
would have expected '/' to return with 'main 0.166001' while '/admin/' 
to halt.   In other words I would expect that the 'hook before' is kept 
within the scope of the prefix '/admin' and not bleed over to the undef 
prefix.

Any ideas on what is happening?

Thanks,
