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.

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.
