Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

How can I capture an Error from a perl module in a perl script?

I have a perl script using a module, and when the module encounters an error it dies and prints an error to the screen. I need to capture this output it, manipulate it, and then print it out.

Any ideas?

    Use eval.

    use SomeModule;
my $foo = SomeModule->new;
eval { $foo->die_die_die };
if ($@) {
    print "There was a problem, but we didn't die: $@";
}
else {
    print "Not a problem.";
}

    As the code above suggests, eval will (usually) prevent the module from dieing and $@ will contain the error.
