NAME

       Dancer::Error - class for representing fatal errors

SYNOPSIS

           # taken from send_file:
           use Dancer::Error;

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

           $error->render;

DESCRIPTION

       With Dancer::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 Dancer
       uses as well under debugging to catch errors and show them on screen.

ATTRIBUTES

   code
       The code that caused the error.

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

   title
       The title of the error page.

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

   message
       The message of the error page.

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

   exception
       The exception that caused the error. If the error was not caused by an
       exception, returns undef. Exceptions are usually objects that inherits
       of Dancer::Exception.

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

METHODS/SUBROUTINES

   new
       Create a new Dancer::Error object.

       title

       The title of the error page.

       type

       What type of error this is.

       code

       The code that caused the error.

       message

       The message that will appear to the user.

       exception

       The exception that will be useable by the rendering.

   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.

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

   render
       Renders a response using Dancer::Response.

   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.

   _censor
       An internal method that tries to censor out content which should be
       protected.

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

   _html_encode
       Internal method to encode entities that are illegal in (X)HTML. We
       output as UTF-8, so no need to encode all non-ASCII characters or use a
       module.  FIXME : this is not true anymore, output can be any charset.
       Need fixing.
