I think that people look at DBM::Deep and go "It can't be that simple, so it's got to be really hard cause I don't understand it." This is your code, with the changes needed to make it DBM::Deep'ed.
# First script, to populate the db file:
use DBM::Deep;
our %services;
tie %services, 'DBM::Deep', 'file.db';
%services = (
1 => {
name => "service1",
host => { host1 => 1 },
},
2 => {
name => "service2",
host => { host0 => 2, host5 => 2 },
},
);
######################
# Second script, to print the services.
our %services;
tie %services, 'DBM::Deep', 'file.db';
print "----------------Menu-----------------------------------------\n
+";
print "Please enter the number of the service and press return\n";
print "-------------------------------------------------------------\n
+";
for $row (sort keys %services){
my $service=$services{$row};
print "$row\t $service->{ name }\n";
}
print "Please enter number -->";
That's it. Note that your usage of %services doesn't change at all.
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
