Hanging out here

Hello All,

I have been here for a long time, but I just read stuff. I have not mustered
enough energy to really check what Perl is all about until yesterday.
Write-only, cowboy language or something pretty cool. I spent few hours
going through learn.perl site stuff. I was really impressed. To me this is
indeed a cool language.

However, I noticed that among beginners here their concerns are mainly file
manipulation, string manipulation and hash table. Shouldn't someone make a
note with simple examples and put it on the internet? And I would want to
see codes from experts here once in a while with their design's reasons.

I have my own issues, and the most confusing part of Perl to me is this
thing called context. Why do we have it in Perl? What is its gain to be
language ? And another thing I am having issue to figure out is when it is
really needed is \&hoom, when hoom is a sub. I know from C , that if one is
to use function as a parameter that it should be in the form of address.

Apart from context, are there other hidden gems I need to know?

I would want to also thank the author of Learning Perl the Hard Way (Allen
B. Downey). I would want that book to be called Learning Perl the Soft Way.

Finally , this group is awesome ... with kind experts and mentors. I really
appreciate you help and time.

Regards,
Emeka

Aside from learn.perl.org which is under-maintained and incomplete, I've been
maintaining an alternative Perl beginners site on http://perl-begin.org/ ,
which is much better. Check it out too.

We're covering file manipulation, string manipulation and hash tables
extensively on the various resources of http://perl-begin.org/ . However, often
newcomers come with unique problems which require understanding of the
programming primitives provided by Perl and how to combine them to produce a
greater solution. This is something that cannot be taught from examples, and if
you desire examples you can look at:

http://rosettacode.org/

What kind of codes from experts? Experts here often give code as answer to
questions. Isn't it good enough?

See:

http://perl-begin.org/tutorials/modern-perl/xhtml/chapter_01 .html#context_philosophy

\&subroutine_name takes a reference to an existing package-scope subroutine
called "subroutine_name":

[CODE]
sub subroutine_name
{
# Do something
}

..
..
..
# later on:
my $sub_ref = \&subroutine_name;

# Silly example:
$sub_ref->(1,2,3);
[/CODE]

If you omit the "\&" you have a bareword, that may be considered a string
without strict/warnings or may be a subroutine call with trailing parenthesis.

I recall a presentation by Reuven Lerner about 5 things every Perl programmer
should know. Also see:

http://perl-begin.org/tutorials/bad-elements/

Ah, I've heard a few bad things about that book, but I'm not sure they are
substantiated. There's also "Impatient Perl":

Sorry but most will only reply to code with code. If you don't supply
code with your questions, you will get answers (and references to look
up) but usually not code. That's because it's difficult to supply an
exact answer without seeing the details of what exactly is going on.

And if you're going to post code, try to isolate the problem. This
makes it clearer what you are asking and you are likely to get an answer
quicker.

Goke,

I based in Port-Harcourt. But I would very much like to be part of your
meetup. Could you give me details and your schedule?
