Re: Learning how to use the Error module by example

[broquaint]

Here's a little script I knocked up to test the capabilities of Error

use Error qw( :try );

sub foo {
  warn "calling bar()\n";
  bar();
}

sub bar {
  throw Error::Simple("test error");
}

sub evaltest {
  require Blah::Blah::Blah;
  Blah::Blah::Blah->new();
}

sub run {
  warn "TEST 1\n";
  try {
    warn "calling foo()\n";
    foo();
    warn "foo called()\n";
  } catch Error::Simple with {
    my $E = shift;
    warn "Caught error: $E";
  };
  
  warn "TEST 2\n";

  try {
    warn "calling evaltest()\n";
    evaltest();
  } catch Error::Simple with {
    warn "Caught error: $_[0]\n";
  };

  try {
    throw Error::Simple("except me");
  } except {
    return {
      Error => sub { warn "whoa: $_[0]\n" },
      'Error::Simple' => sub { warn "wah: $_[0]" },
    };
  };

  warn "\nTesting done\n";
}

main->run();

Essentially it'll catch anything that an eval block will and I've generally found it'll DTRT :)
