13 End user information
14 This module provides a plugin framework for displaying runtime
15 information about your CGI::Application app in a popup window. A sample
16 Timing plugin is provided to show how it works:
17 BEGIN { $ENV{'CAP_DEVPOPUP_EXEC'} = 1; } # turn it on for real
19 use CGI::Application::Plugin::DevPopup;
20 use CGI::Application::Plugin::DevPopup::Timing;
21 The rest of your application follows
23 ...
24 Now whenever you access a runmode, a window pops up over your content,
26 showing information about how long the various stages have taken.
27 Adding other CAP::DevPopup plugins will get you more information. A
28 HTML::Tidy plugin showing you how your document conforms to W3C
29 standards is available: see CGI::Application::Plugin::HtmlTidy.
30 The output consists of a Table of Contents, and a bunch of reports. A
32 rough translation into plain text could look like this:
33 Devpopup report for My::App -> add_timing
35 * Timings - Total runtime: 3.1178 sec.

50 The reports expand and collapse by clicking on the ToC entry or the
52 report header.
53 Developer information
55 Creating a new plugin for DevPopup is fairly simple. CAP::DevPopup
56 registers a new callback point (named "devpopup_report"), which it
57 uses to collect output from your plugin. You can add a callback to that
58 point, and return your formatted output from there. The callback has
59 this signature:
60 sub callback($cgiapp_class, $outputref)
62 You pass your output to the devpopup object by calling
64 $cgiapp_class->devpopup->add_report(
66 title => $title,
67 summary => $summary,
68 report => $body,
69 );
70 You are receiving $outputref, because DevPopup wants to be the last one
72 to be called in the postrun callback. If you had wanted to act at
73 postrun time, then please do so with this variable, and not through a
74 callback at postrun.
75 The "on" switch
77 Since this is primarily a development plugin, and you wouldn't want it
78 to run in your production code, an environment variable named
79 CAP_DEVPOPUP_EXEC has to be set to 1 for this module to function, and
80 it must be present at compile time. This means you should place it in a
81 BEGIN{} block, or use SetEnv or PerlSetEnv (remember to set those
82 before any PerlRequire or PerlModule lines).
83 Absence of the environment variable turns this module into a no-op:
85 while the plugin and its plugins are still loaded, they won't modify
86 your output.

89 o CGI::Application::Plugin::DevPopup::Timing,
90 CGI::Application::Plugin::DevPopup::Log and
91 CGI::Application::Plugin::DevPopup::HTTPHeaders are bundled with this
92 distribution.
93 o CGI::Application::Plugin::HtmlTidy integrates with this module.
94 o CGI::Application::Plugin::TT integrates with this module.

97 • devpopup
98 This method is the only one exported into your module, and can be
100 used to access the underlying DevPopup object. See below for the
101 methods that this object exposes.
102
104 • add_report( %fields )
105 Adds a new report about the current run of the application. The
107 following fields are supported:
108 • title
110 A short title for your report
112 • summary
114 An optional one- or two-line summary of your findings
116 • report
118 Your full output
120 • severity
122 An optional value specifying the importance of your report.
124 Accepted values are qw/debug info warning error fatal/.
125 This value is used to color-code the report headers.
126 • script
128 If you have custom javascript, then please pass it in
130 through this field. Otherwise if it's embedded in your
131 report, it will break the popup window. I will take care of
132 the surrounding "<script"> tags, so just the code body is
133 needed.
