NAME

       App::Info::Handler::Prompt - Prompting App::Info event handler

SYNOPSIS

         use App::Info::Category::FooApp;
         use App::Info::Handler::Print;

         my $prompter = App::Info::Handler::Print->new;
         my $app = App::Info::Category::FooApp->new( on_unknown => $prompter );

         # Or...
         my $app = App::Info::Category::FooApp->new( on_confirm => 'prompt' );

DESCRIPTION

       App::Info::Handler::Prompt objects handle App::Info events by printing their messages to
       "STDOUT" and then accepting a new value from "STDIN". The new value is validated by any
       callback supplied by the App::Info concrete subclass that triggered the event. If the
       value is valid, App::Info::Handler::Prompt assigns the new value to the event request. If
       it isn't it prints the error message associated with the event request, and then prompts
       for the data again.

       Although designed with unknown and confirm events in mind, App::Info::Handler::Prompt
       handles info and error events as well. It will simply print info event messages to
       "STDOUT" and print error event messages to "STDERR". For more interesting info and error
       event handling, see App::Info::Handler::Print and App::Info::Handler::Carp.

       Upon loading, App::Info::Handler::Print registers itself with App::Info::Handler, setting
       up a single string, "prompt", that can be passed to an App::Info concrete subclass
       constructor. This string is a shortcut that tells App::Info how to create an
       App::Info::Handler::Print object for handling events.
