Hmm, looks good but I want to use it in script not from commandline. Can you
rewrite it like this:
#!/usr/bin/perl
use strict;
my ($month, $year) = map .... ;

I stand corrected. Other than eval and do 'slurp' does everything in the
above idiom.

Really ? I have not heard of it in 10+ years in being in s/w industry.
I need no JAPH signature. Advicing on signature is probably going a little
too far ;-) [ No flames please :-) ]

the signature is a usenet thing and predates perl, japhs and your short

Subject: Perl Best Practices - Code Formatting.
Message-Id: <1182402088.951116@sj-nntpcache-2.cisco.com>
I was reading Perl Best Practices by Respected Damian Conway
and he rather strongly advices using K&R style of code format as opposed to
BSD style or GNU style.
[ In Amazon reviews this advice was not very well received ]
For reference:
K&R style below
============
for my $item ( @list ) {
.......
.......
}
BSD style below
============
for my $item ( @list )
{
....
....
}
OTOH in Damian Conway's classic "Object Oriented Perl", he chooses to use
BSD style in the book.
Change of heart Mr. Conway ?
I know people feel strongly about code layout/format and "bracing
technology" - I would like to know
what folks are using in their scripts and modules.
I am talking about production scripts and modules ( possibly multiple people
team ) with sufficient complexity.
( Several thousand Perl line count at the minimum )
Which style appeals to you more and which one do you use ?
Regards.
Asim Suter
PS: It does not matter - but I find BSD style more appealing.

And your position is that the 1st is more painful than the 2nd?
Personally, I'd say repeatedly typing the same thing is a pain...

Neither of them cause errors.

Actually, though Emacs is the epitome of extensibility, the "E" stands
for "Editor." "EMACS" is simply short for Editor MACroS, and was
originally implemented as a set of TECO macros.
There's also the joke that EMACS stands for Esc Meta Alt Ctrl Shift,
due to it's (often overwhelmingly) large and sometimes complex set of
keystroke combinations used to invoke various editing functions. This
view is usually put forth by the vi camp during editor wars.
Speaking of which, vi is a piece of wombat do. ;-)

Windows text editors are not normal: most are devoid of all but the most
primitive functions and are further hampered by having an interface that
required frequent time wasting hand transfers from keyboard to mouse
because, if they provide keyboard equivalents at all, these are
remarkably unmemorable and/or undocumented.
Ask anybody who used early versions of Word and you'll hear just how
much faster Word for DOS 5 was than any of its Windows incarnations.
This was because all commands were keystrokes so a skilled typist could
keep both hands on the keyboard all the time. WinWord's interface is a
clunker by comparison.
As for documentation, lets look at vi. Not a great editor, but every
*nix variation has it installed and any fool can learn to use it in
about 2 hours flat and it does at least have good pattern matching.
Can't find its documentation? Never heard of manpages ("man vi") or
apropos ("apropos vi")? My copy of vi understands ":help" and tells you
so if you start it without any arguments.
Amongst its benefits are that you can do anything its capable of by
using only a standard QUERTY keyboard plus ESC - no function keys, etc
are needed - which can save your bacon if somebody misconfigured your
console or the computer is dieing. Beyond that it has user-configurable
KEY BINDINGS so you can also set it up to suit both yourself and that
fancy keyboard in front of you.

You mean that Alt-Esc or Windows-e aren't weird? How long is it since
you tried to use Windows with a dead mouse? There are a set of arcane
keystrokes to replace anything you can do with a mouse but I bet 99% of
windows users don't know any of them apart from TAB and CTRL-ALT-DEL.

If you can't learn enough vi to get by with in half a morning you're
probably well out of your depth here on comp.lang.java.programmer.
Oh, I forgot: you don't read manuals so you ARE out of your depth.

"Catch 22" is the right phrase here: just catch Emacs 22 and get
started. Its out-of-the-box configuration is quite sensible.

It has not occured to you that actually thousands of people read those
postings? And they are heavily crossposted to boot (redirecting
followup to comp.emacs, I would suggest everybody else do the same).
And you have really nothing worthwhile to contribute. So if there is
some rating system (I don't use Google Groups so can't tell) in place,
your postings would certainly be good candidates for downrating.
Not that this posting of mine is much better, and actually the
followup-to comp.emacs would indicate that this is about Emacs.
However, you have still not given any information about what, if any,
version of Emacs your very vaguely expressed experiences are supposed
to have come from.

Uh, is there some monetary compensation for star ratings? Or what's
the deal? Really, if somebody can come up with a better group for
followups, feel free to direct there.

Ok, I'm trying to learn perl for a potential position.
I would consider myself a very experienced php programmer with a
little exposure to perl.
As far as syntax goes, perl seems pretty easy (some things I even like
a lot). I have an ubuntu feistry server that I've setup with
mod_perl. It works great for parsing simple stuff but now I'm ready
to extend the functionality a bit and want to connect to postgresql,
etc.
Admittedly this is more a systems things than a programming thing but
I need to get things in place so I can program and learn. First of
all, how does mod perl work with the cpan packages? When I install
something using cpan should I be able to use that module (ie "use
module::module") immediately after? So far that has not been my
experience. Furthermore, can I use the cgi stuff in cpan when I'm
using mod_perl, like cgi::ajax?? I've just never had to deal with all
this with php so it's feeling very overwhelming in how it all works
together (I'm trying to read books and have been googling for hours to
make sense of it).
Finally, and most frustrating is getting error or warning feedback.
Where do I go? I currently am trying to connect to my db with:
$dbh = DBI->connect("dbi:Pg:dbname=ecommerce;host=127.0.0.1",
"cendrizzi", "************", {AutoCommit => 0});
I then try to do stuff with $dbh and nothing happens but I don't get
errors either. I have no idea what is going on or if I can even
successfully connect to the db?! In PHP you can turn on errors and
warnings to display them in the page, I'm sure Perl is just
different. How can I troubleshoot this stuff?
Thanks for any help you can provide me with.
