VERSION

SYNOPSIS

12           # taken from send_file:
13           use Dancer2::Core::Error;
14
15           my $error = Dancer2::Core::Error->new(
16               status    => 404,
17               message => "No such file: `$path'"
18           );
19
20           Dancer2::Core::Response->set($error->render);
21

DESCRIPTION

23       With Dancer2::Core::Error you can throw reasonable-looking errors to
24       the user instead of crashing the application and filling up the logs.
25
26       This is usually used in debugging environments, and it's what Dancer2
27       uses as well under debugging to catch errors and show them on screen.
28

31   charset
32   type
33       The error type.
34
35   title
36       The title of the error page.
37
38       This is only an attribute getter, you'll have to set it at "new".
39
40   status
41       The status that caused the error.
42
43       This is only an attribute getter, you'll have to set it at "new".
44

47

METHODS

49   my $error=new Dancer2::Core::Error(status    => 404, message => "No such
50       file: `$path'");
51       Create a new Dancer2::Core::Error object. For available arguments see
52       ATTRIBUTES.
53
54   supported_hooks ();
55   throw($response)
56       Populates the content of the response with the error's information.  If
57       $response is not given, acts on the app attribute's response.
58
59   backtrace
60       Show the surrounding lines of context at the line where the error was
61       thrown.
62
63       This method tries to find out where the error appeared according to the
64       actual error message (using the "message" attribute) and tries to parse
65       it (supporting the regular/default Perl warning or error pattern and
66       the Devel::SimpleTrace output) and then returns an error-highlighted
67       "message".
68
69   environment
70       A main function to render environment information: the caller (using
71       "get_caller"), the settings and environment (using "dumper") and more.
72
73   get_caller
74       Creates a stack trace of callers.
75

FUNCTIONS

77   _censor
78       An private function that tries to censor out content which should be
79       protected.
80
81       "dumper" calls this method to censor things like passwords and such.
82
83   my $string=_html_encode ($string);
84       Private function that replaces illegal entities in (X)HTML with their
85       escaped representations.
86
87       html_encode() doesn't do any UTF black magic.
88
89   dumper
90       This uses Data::Dumper to create nice content output with a few
91       predefined options.
