NAME

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

VERSION

       version 1.1.2

SYNOPSIS

           use Dancer2::Core::Error;

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

           $error->throw;

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_stacktrace
   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
       Show the surrounding lines of context at the line where the error was thrown.

       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".

   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.
