NAME

Acme::JavaTrace - Module for using Java-like stack traces

VERSION

Version 0.07

SYNOPSIS

On the command-line: 
     perl -wMAcme::JavaTrace program_with_strange_errors.pl

Inside a module:

     use Acme::JavaTrace;
     warn "some kind of non-fatal exception occured";
     die "some kind of fatal exception occured";

DESCRIPTION

"<buzzword>"This module tries to improves the Perl programmer experience by porting the Java paradigm to print stack traces, which is more professional than Perl's way. "</buzzword>"

This is achieved by modifying the functions "warn()" and "die()" in order to replace the standard messages by complete stack traces that precisely indicates how and where the error or warning occurred. Other than this, their use should stay unchanged, even when using "die()" inside "eval()".

For a explanation of why I wrote this module, you can read the slides of my lightning talk Entreprise Perl, available here: <http://maddingue.org/conferences/yapc-eu-2004/entreprise-perl/>

OPTIONS

Options can be set at import time using: 
     perl -wMDevel::SimpleTrace=option1,option2

or

     use Devel::SimpleTrace qw(option1 option2);

Available options are:

"showrefs"
Using this option will tell "Devel::SimpleTrace" to stringify objects and references passed in argument to "die()". This option is disabled by default in order to leave objects and references untouched.

EXAMPLE

Here is an example of stack trace produced by "Acme::JavaTrace" using a fictional Perl program: 
     Exception: event not implemented
             at MyEvents::generic_event_handler(workshop/events.pl:26)
             at MyEvents::__ANON__(workshop/events.pl:11)
             at MyEvents::dispatch_event(workshop/events.pl:22)
             at MyEvents::call_event(workshop/events.pl:17)
             at main::(workshop/events.pl:30)

Please note that even the professionnal indentation present in the Java environment is included in the trace.

DIAGNOSTICS

Unknown option: %s
(W) This warning occurs if you try to set an unknown option.

CAVEATS

This module is currently not compatible with other modules that also work by overriding "die()" and "warn()", like "CGI::Carp".

BLAME

Java, for its unhelpful kilometre-long stack traces.
