NAME
Dancer::Core::Error - Class representing fatal errors
VERSION
version 1.9999_02
SYNOPSIS
# taken from send_file:
use Dancer::Error;
my $error = Dancer::Error->new(
status => 404,
message => "No such file: `$path'"
);
Dancer::Response->set($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
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 $error=new Dancer::Core::Error(status => 404, message => "No such file: `$path'");
Create a new Dancer::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 context 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-higlighted 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 strack 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.
