How do I declare/create a structure?

Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

In general, you don't ``declare'' a structure. Just use a (probably anonymous) hash reference. See the perlref manpage and the perldsc manpage for details. Here's an example:

    $person = {};                   # new anonymous hash
    $person->{AGE}  = 24;           # set field AGE to 24
    $person->{NAME} = "Nat";        # set field NAME to "Nat"

If you're looking for something a bit more rigorous, try the perltoot manpage.

[shmem]: Discipulus: while (readdir DIR) works fine
[Discipulus]: Eataly vs World(coffe) ;=)
[Discipulus]: shemem i wrote it directly.. but when i tested it i got a lot of 'undefined value..'
[Corion]: Oh, poor Trump can't get a break. Even the Vatican only sends the second in command to greet him...
[shmem]: Discipulus: readdir has the same semantics as readline (a.k.a <>). Have another coffee ☕ ;-)
[Discipulus]: ah! just with my old system perl (5.8.8) was needed
[Corion]: Has anybody toyed around with Mastodon? There is a Perl module for it, but I'm not sure that it's a yak worth chasing
[Corion]: On the upside, maybe running that for my family would be interesting, or at least for myself
