12 # taken from send_file:
13 use Dancer::Error;
14
15 my $error = Dancer::Error->new(
16 code => 404,
17 message => "No such file: `$path'"
18 );
19
20 $error->render;
21
23 With Dancer::Error you can throw reasonable-looking errors to the user
24 instead of crashing the application and filling up the logs.
25
26 This is usually used in debugging environments, and it's what Dancer
27 uses as well under debugging to catch errors and show them on screen.
28
30 code
31 The code that caused the error.
32
33 This is only an attribute getter, you'll have to set it at "new".
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 message
41 The message of the error page.
42
43 This is only an attribute getter, you'll have to set it at "new".
44
45 exception
46 The exception that caused the error. If the error was not caused by an
47 exception, returns undef. Exceptions are usually objects that inherit
48 from Dancer::Exception.
49
50 This is only an attribute getter, you'll have to set it at "new".
51
53 new
54 Create a new Dancer::Error object.
55
56 title
57
58 The title of the error page.
59
60 type
61
62 What type of error this is.
63
64 code
65
66 The code that caused the error.
67
68 message
69
70 The message that will appear to the user.
71
72 exception
73
74 The exception that will be useable by the rendering.
75
76 backtrace
77 Create a backtrace of the code where the error is caused.
78
79 This method tries to find out where the error appeared according to the
80 actual error message (using the "message" attribute) and tries to parse
81 it (supporting the regular/default Perl warning or error pattern and
82 the Devel::SimpleTrace output) and then returns an error-highlighted
83 "message".
84
85 tabulate
86 Small subroutine to help output nicer.
87
88 dumper
89 This uses Data::Dumper to create nice content output with a few
90 predefined options.
91
92 render
93 Renders a response using Dancer::Response.
94
95 environment
96 A main function to render environment information: the caller (using
97 "get_caller"), the settings and environment (using "dumper") and more.
98
99 get_caller
100 Creates a stack trace of callers.
101
102 _censor
103 An internal method that tries to censor out content which should be
104 protected.
105
106 "dumper" calls this method to censor things like passwords and such.
107
108 _html_encode
109 Internal method to encode entities that are illegal in (X)HTML. We
110 output as UTF-8, so no need to encode all non-ASCII characters or use a
111 module. FIXME : this is not true any more, output can be any charset.
112 Need fixing.
