NAME

       Catalyst::Plugin::StackTrace - Display a stack trace on the debug screen

SYNOPSIS

	   use Catalyst qw/-Debug StackTrace/;

DESCRIPTION

       This plugin will enhance the standard Catalyst debug screen by including a stack trace of your appliation up to the point where the error
       occurred.  Each stack frame is displayed along with the package name, line number, file name, and code context surrounding the line number.

       This plugin is only active in -Debug mode by default, but can be enabled by setting the "enable" config option.

CONFIGURATION

       Configuration is optional and is specified in MyApp->config->{stacktrace}.

   enable
       Allows you forcibly enable or disalbe this plugin, ignoring the current debug setting. If this option is defined, its value will be used.

   context
       The number of context lines of code to display on either side of the stack frame line.  Defaults to 3.

   reverse
       By default, the stack frames are shown in from "top" to "bottom" (newest to oldest). Enabling this option reverses the stack frames so they
       will be displayed "bottom" to "top", or from the callers perspective.

   verbose
       This option sets the amount of stack frames you want to see in the stack trace.	It defaults to 0, meaning only frames from your
       application's namespace are shown.  You can use levels 1 and 2 for deeper debugging.

       If set to 1, the stack trace will include frames from packages outside of your application's namespace, but not from most of the Catalyst
       internals.  Packages ignored at this level include:

	   Catalyst
	   Catalyst::Action
	   Catalyst::Base
	   Catalyst::Dispatcher
	   Catalyst::Engine::*
	   Catalyst::Plugin::StackTrace
	   Catalyst::Plugin::Static::Simple
	   NEXT
	   main

       If set to 2, the stack trace will include frames from everything except this module.

INTERNAL METHODS

       The following methods are extended by this plugin.

       execute
	   In execute, we create a local die handler to generate the stack trace.

       finalize_error
	   In finalize_error, we inject the stack trace HTML into the debug screen below the error message.

       setup
