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.
CONFIGURATION
Configuration is optional and is specified in
MyApp->config->{stacktrace}.
context
The number of context lines of code to display on either side of the
stack frame line. Defaults to 3.
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.
