they do the same thing. But if you plan to re-use the app1 package in another application, you don't want to have "prefix" hardcoded in the package, and you will prefer to do a "load_app 'app1', prefix => '/whatever'". but you're right, we should update the cookbook to explain why this solution is better :) On Sat, Oct 2, 2010 at 8:28 PM, P Kishor <punk.kish@gmail.com> wrote:

Hi

...

I was using the following idiom, and everything was working fine

---- package app; use Dancer ':syntax'; use Dancer::Plugin::Ajax;

load_app "app::app1", prefix => "/app1"; load_app "app::app2", prefix => "/app2";

..

true; ----

package app::app1; use Dancer ':syntax';

..

true; ----

package app::app2; use Dancer ':syntax';

..

true; ----

The above was a holdover from earlier versions of Dancer, but, as I noted above, it was working fine. Today I noticed that the Dancer::Cookbook has a different suggestion, so I implemented that and ran into a problem. My new implementation is

---- package app; use Dancer ':syntax'; use Dancer::Plugin::Ajax;

use app::app1; use app::app2;

prefix undef;

..

true; ----

package app::app1; use Dancer ':syntax'; prefix 'app1'; ..

true; ----

package app::app2; use Dancer ':syntax'; prefix 'app2'; ..

true; ----

I get the following error

Error while loading /Users/punkish/Sites/app/app.pl: unable to load application app : not a valid prefix: `app', must start with a / at /usr/local/lib/perl5/site_perl/5.12.1/Dancer/App.pm line 32., referer: http://app.local/app1/

What gives?

a prefix must start with '/', if the '/' is missing in the cookbook, it's an error, and that will be fixed right away.

Yes, it is missing in the cookbook.

...

However, I prefer your first solution :) (load_app "app::app1", prefix => "/app1";)

Hmmm.... then shouldn't the cookbook show the preferred solution -- I am assuming you know way more than I do about Dancer, and if you prefer a particular solution, that *should* be the preferred solution, no? ;-)
