I've stumbled upon the MooseX::Declare documentation, and I have to say "WOW!". That looks really nice! I think it's the cleanest OOP syntax Perl has. use MooseX::Declare; class BankAccount { has 'balance' => ( isa => 'Num', is => 'rw', default => 0 ); method deposit (Num $amount) { $self->balance( $self->balance + $a...
Summary I've got a table of items that go in pairs. I'd like to self-join it so I can retrieve both sides of the pair in a single query. It's valid SQL (I think), the SQLite engine actually does accept it, but I'm having trouble getting DBIx::Class to bite the bullet. Minimal example package Schema; use parent 'DBIx::Class::Schema';...

I have a long-ish Perl script that runs just fine, but always gives this warning: Can't find string terminator '"' anywhere before EOF at -e line 1 I've read elsewhere online that this is because of a misuse of single or double quotes and the error generally stops the script from running, but mine works. I'm pretty sure I've used my ...

I'm still relatively new to Perl Programming, but I know how Perl 5 OO basically works. However, I have never created any project with Perl 5 OO, so I'm quite sure I will run into many pitfalls.

I'm writing a complex script that takes the XML backup of a Blogger blog and converts it to InDesign Tagged Text to be laid out in a book.

I have a Perl program that has a GTK2 GUI (via the Gtk2 package). This program also opens a network socket (actually via LWP) in another thread, and continuously makes a request for a certain URL, waiting for an event to happen.
