NAME

       Dancer2::Core::Error - Class representing fatal errors

VERSION

       version 0.166001

SYNOPSIS

           # taken from send_file:
           use Dancer2::Core::Error;

           my $error = Dancer2::Core::Error->new(
               status    => 404,
               message => "No such file: `$path'"
           );

           Dancer2::Core::Response->set($error->render);

DESCRIPTION

       With Dancer2::Core::Error you can throw reasonable-looking errors to the user instead of
       crashing the application and filling up the logs.

       This is usually used in debugging environments, and it's what Dancer2 uses as well under
       debugging to catch errors and show them on screen.

ATTRIBUTES

   show_errors
   charset
   type
       The error type.

   title
       The title of the error page.

       This is only an attribute getter, you'll have to set it at "new".

   status
       The status that caused the error.

       This is only an attribute getter, you'll have to set it at "new".

   message
       The message of the error page.

METHODS

   my $error=new Dancer2::Core::Error(status    => 404, message => "No such file: `$path'");
       Create a new Dancer2::Core::Error object. For available arguments see ATTRIBUTES.

   supported_hooks ();
   throw($response)
       Populates the content of the response with the error's information.  If $response is not
       given, acts on the app attribute's response.

   backtrace
       Create a backtrace of the code where the error is caused.

       This method tries to find out where the error appeared according to the actual error
       message (using the "message" attribute) and tries to parse it (supporting the
       regular/default Perl warning or error pattern and the Devel::SimpleTrace output) and then
       returns an error-highlighted "message".

   tabulate
       Small subroutine to help output nicer.

   environment
       A main function to render environment information: the caller (using "get_caller"), the
       settings and environment (using "dumper") and more.

   get_caller
       Creates a stack trace of callers.

FUNCTIONS

   _censor
       An private function that tries to censor out content which should be protected.

       "dumper" calls this method to censor things like passwords and such.

   my $string=_html_encode ($string);
       Private function that replaces illegal entities in (X)HTML with their escaped
       representations.

       html_encode() doesn't do any UTF black magic.

   dumper
       This uses Data::Dumper to create nice content output with a few predefined options.
