VERSION

version 0.160003

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.
