       CGI::Application::Plugin::DevPopup - Runtime cgiapp info in a popup window


       version 1.08


   End user information
       This module provides a plugin framework for displaying runtime information about your
       CGI::Application app in a popup window. A sample Timing plugin is provided to show how it

           BEGIN { $ENV{'CAP_DEVPOPUP_EXEC'} = 1; } # turn it on for real
           use CGI::Application::Plugin::DevPopup;
           use CGI::Application::Plugin::DevPopup::Timing;

           The rest of your application follows

       Now whenever you access a runmode, a window pops up over your content, showing information
       about how long the various stages have taken. Adding other CAP::DevPopup plugins will get
       you more information. A HTML::Tidy plugin showing you how your document conforms to W3C
       standards is available: see CGI::Application::Plugin::HtmlTidy.

       The output consists of a Table of Contents, and a bunch of reports. A rough translation
       into plain text could look like this:

           Devpopup report for My::App -> add_timing

           * Timings - Total runtime: 3.1178 sec.

           | Timings                                                               |
           | Application started at: Thu Sep 22 02:55:35 2005                      |
           | From                       To                         Time taken      |
           | init                       prerun                     0.107513 sec.   |
           | prerun                     before expensive operation 0.000371 sec.   |

           | after expensive operation  load_tmpl(dp.html)         0.000379 sec.   |
           | load_tmpl(dp.html)         postrun                    0.002849 sec.   |

       The reports expand and collapse by clicking on the ToC entry or the report header.

   Developer information
       Creating a new plugin for DevPopup is fairly simple. CAP::DevPopup registers a new
       callback point (named "devpopup_report"),  which it uses to collect output from your
       plugin. You can add a callback to that point, and return your formatted output from there.
       The callback has this signature:

           sub callback($cgiapp_class, $outputref)

       You pass your output to the devpopup object by calling

                       title   => $title,
                       summary => $summary,
                       report  => $body,

       You are receiving $outputref, because DevPopup wants to be the last one to be called in
       the postrun callback. If you had wanted to act at postrun time, then please do so with
       this variable, and not through a callback at postrun.

   The "on" switch
       Since this is primarily a development plugin, and you wouldn't want it to run in your
       production code, an environment variable named CAP_DEVPOPUP_EXEC has to be set to 1 for
       this module to function, and it must be present at compile time. This means you should
       place it in a BEGIN{} block, or use SetEnv or PerlSetEnv (remember to set those before any
       PerlRequire or PerlModule lines).

       Absence of the environment variable turns this module into a no-op: while the plugin and
       its plugins are still loaded, they won't modify your output.

       ·   devpopup

           This method is the only one exported into your module, and can be used to access the
           underlying DevPopup object. See below for the methods that this object exposes.


       ·   add_report( %fields )

           Adds a new report about the current run of the application. The following fields are

           ·       title

                   A short title for your report

           ·       summary

                   An optional one- or two-line summary of your findings

           ·       report

                   Your full output

           ·       severity

                   An optional value specifying the importance of your report. Accepted values
                   are qw/debug info warning error fatal/. This value is used to color-code the
                   report headers.

           ·       script

                   If you have custom javascript, then please pass it in through this field.
                   Otherwise if it's embedded in your report, it will break the popup window. I
                   will take care of the surrounding "<script"> tags, so just the code body is
