Acme::JavaTrace - Module for using Java-like stack traces
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";
<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.
This is achieved by modifying the functions
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
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 can be set at import time using:
use Devel::SimpleTrace qw(option1 option2);
Available options are:
Using this option will tell
Devel::SimpleTraceto stringify objects and references passed in argument to
die(). This option is disabled by default in order to leave objects and references untouched.
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.
This module is currently not compatible with other modules that also work by overriding
Java, for its unhelpful kilometre-long stack traces.
