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

NAME

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

SYNOPSIS

    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 sildes of my lightning talk Entreprise Perl, available here: http://maddingue.org/conferences/yapc-eu-2004/entreprise-perl/

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 Java traces is included in the trace.

BLAME

Java, for its unhelpful kilometre-long stack traces.
