SYNOPSIS

package Plack::Middleware::Debug::YourPanel;
use parent qw(Plack::Middleware::Debug::Base);
sub run {
my($self, $env, $panel) = @_;
# Do something before the application runs
return sub {
my $res = shift;
# Do something after the application returns
};
}

DESCRIPTION

This is the base class for panels.

METHODS

"run"

This method is called when a request has arrived, before the main application runs. The parameters are $env, the PSGI environment hash reference and $panel, a Plack::Middleware::Debug::Panel object.

If your panel needs to do some response munging, you should return a callback that takes $res the response object. Because you can return a closure, the response filter can also use $env and $panel easily.
