Hey, guess what: everyone's right. There are degrees, though.
I'd say that the ST is scarey because it's a non-obvious idiom,
implemented using highly generic operations (map, mainly),
not because of the magic involved in the implementation.
Different languages have different fundamentals, and you get
to understand them. In Perl, sort's $a and $b or regexps' $1
aren't much more magical than +, because they're so common.
The ST is a little dodgy, because it's quite large - if you're reading
someone else's code, you'd have to check that it *does* do ST, rather
than saying "map...sort..map..uh, ST" - the maps could be there for
other purposes. For that reason, I'd say "comment it". Say it's an ST,
and what it's sorting on, and give some pointer or explanation for the
ST itself. But that's not a reason for dumbing it down.

Subject: ADVICE NEEDED: timelocal() prints wrong result
Message-Id: <E7J8zv.HI@syd.csa.com.au>
Hello,
I admit I might be over-streched atd exhausted at the present time. I hope
I am not asking a question that has obvious answer. I have done a search
through FAQs, Manuals and Perl books. Alas, I am still looking for a solution.
I have written a Perl5 script (I am running Solaris 2.5.1 with Perl 5.003) which calculates differences between certain dates. It all works fine, except that the
results are wrong when timelocal() is used on dates that start in different months.
Here is a piece of code that demonstates the problem:
#!/opt/local/bin/perl
use Time::Local;
$AAA = timelocal(37, 53, 04, 1, Mar, 97);
$BBB = timelocal(37, 53, 22, 27, Feb, 97);
$CCC = ($AAA - $BBB) > 0 ? ($AAA - $BBB) : abs($AAA - $BBB);
$DDD = $CCC / 3600;
printf("%d - %d = %d (%s hours)\n", $AAA, $BBB, $CCC, $DDD);
exit(0);
As a result I get:
852054817 - 854366017 = 2311200 (642 hours)
Totally wrong! Of course, if I specify two dates within the same month, it works
properly.
I am aware of other Perl5 date manipulation modules. At this stage, I would like
to "stick" to standard Perl5 (if possible). Is there something I can do to make
sure that timelocal() always returns the corect answer (even for dates in different
months).
Thank you in advance for any comment (I hope my "crazy" problem

Yes, I know how Pascal works. (In this specific instance, I know the
format for Pascal identifiers, but also in general, I know how Pascal
works.) I know how I just don't see why he needs to have case
inconsistancy for the same identifier to suit the his stated goal "I
don't know about others but I find mixed case greatly improves script
readability."
He can use mixed case. He just needs to keep consistant when refering
to the same variable. I don't see why he is complaining he can't.
Again, I don't feel strongly enough about case sensitive identifiers
to defend why the language _must_ have them, but on the other hand, I
have never thought of them being a problem to complain about.

Hello,
I'm in need of doing a casting in Perl but I don't know how.
Suppose I've got a class A, with methods M1 and M2, and M1 calling
M2.
Now, I create a class B which inherits from A, also with methods M1 and
M2 which override M1 and M2 from A. In method M1 I have to call
A->M1. The problem is that M1 from A will call M2 from B where it is
supposed to call M2 from A!!
Is there a way to avoid this??
Thanks

Just call M2 explicitly as a subroutine, i.e. instead of
$obj->M2(@args):
write
A::M2($obj, @args);

Subject: easy money
Message-Id: <01bc025d$ad8dd9a0$24aa2299@arlen>
Taking 5 minutes to read what follows could be one of the best decisions
you have ever made.
READ THIS!!!!
I saw an article in an internet newsgroup telling me that I could make
$50,000 within a month for an investment of only $5.
I thought it was a huge joke. I spoke to my attorney, friends and family
about it, and they all agreed it was some kind of scam. I can't stand
scams, because usually someone gets burned, and I didn't want it it to be
me. After rejecting the idea at first, I realized all I had to lose was
the $5 in my wallet. I figured what the heck, and decided to give it a
shot.
A friend told me that he invested $5 and two weeks later he began receiving
money in the mail! Soon, hundreds, and then thousands of dollars began to
roll in. Within 4 weeks, he had received a total of $32,445! It came from
everywhere in the world.
If you follow the three steps below, there is no reason why the same
shouldn't happen to you! This is a legitimate investment opportunity. You
invest $5, and you receive a return on your investment. So does the next
investor.
NOT ILLEGAL, NOT A CHAIN LETTER - PERFECTLY LEGITIMATE.
If you are not interested, then don't participate, but please print this
article and pass it on to someone who may be interested, so they can take
advantage.
The procedure is simple:
1) Write your name, address, and country on 5 sheets of paper. Below
that, write the words, "Please add me to your mailing list." This creates a
service out of this money making system and thus making it completely
legal. You are not just randomly sending a dollar to someone, you are
paying one dollar for a legitimate service. You should use thick dark
paper to discourage mail theft. Fold a $1 bill in each piece of paper, (no
checks or money orders). The folding of the paper around the bill will
insure its arrival to its recipient.
THIS STEP IS IMPORTANT!! and mail them to the following 5 addresses:
1. Binti Jua Hayes
616 NW 22nd St.
Wilton Manors, FL 33311
2. Iffat Ara Sadique
183-11, Hillside Ave., Apt 6K
Jamaica Estates, NY 11432
3. Adam Gross
4730 Pond Creek Road
Alexandria, KY 41001-9766
4. Roger. Romero
7121B Dakota Ave.
Fairchild AFB, WA 99011
5. Susan Walther
910 Waybourne Way
Lake Mary, FL 32746
2) Now remove the top name from the list, and move the other four names
up. In other words, #5 becomes #4 and so on. Put your name as the fifth
one on the list. You can do this by simply retyping the article or
reposting it to other newsgroups with the edited addresses.
3) Post the article to at least 200 newsgroups. There are 19,000, so it
shouldn't be hard to find that many.
LET'S ALL TAKE CARE OF EACH OTHER BY BEING HONEST AND BY PUTTING FORTH 120
PERCENT INTO THIS PROFITABLE & AMAZING SYSTEM!!! You'll reap the benefits,
believe me!!!
If you can UUE encode the file when uploading, that will make it easier
for the people to receive it and have it downloaded to their hard drive.
That way they get a copy of the article right on their computer without
hassles of viewing and then saving the article from the File menu. Don't
alter the file type, leave it as an MS-DOS Text file. The best test is to
be able to view this file using Microsoft's
Notepad for Windows 3.x or WordPad for Windows '95. If the margins look
right without making the screen slide left or right when at the ends of the
sentences, you're in business!
You are now in the mail order investment business, and should start seeing
returns within a week or two. Of course, the more newgroups you post to,
the greater your return will be. If you wish to remain anonymous, you may
use a psuedonym, but make sure your address is correct.
Now, here is why the system works:
The internet is growing at a tremendous rate - it doubles in size every 4
months. Think about it. You see those 'Make Money Fast' posts more and
more. All that growth means profits for everyone who participates. There
are no losers.
Of every 200 posts I made, I received 5 responses. Yes, only 5. You make
$5 for every 200 posts with your name at #5.
Each person who sent you $1 now also makes 200 additional postings with
your name at #4. ie. 1000 postings. On average therefore, 50 people will
send you $1 with your name at #4. $50.
Your 50 new agents make 200 postings each with your name at #3 or 10,000
postings. Average return 500 people=$500. They make 200 postings each
with your name at #2=100,000 postings=5000 return at $1 each=$5000.
Finally, 5,000 people make 200 postings with your name at #1 and you get a
return of $50,000 before your name drops off the list. AND THATS IF
EVERYONE DOWN THE LINE MAKES ONLY 200 POSTINGS! Total income in one cycle
= $55,000.
>From time to time, when you see your name no longer on the list, you take
the latest posting that appears in the newsgroups, and send out another $5,
and put your name at #5, and start posting again. Remember, 200 postings
is only a guideline. The more you post, the greater the return.
Lets review why you should do this. THE ONLY COST IS $5, AND 5 STAMPS, AND
5 ENVELOPES. Anyone can afford $5 for such an effortless investment with
such SPECTACULAR RETURNS.
Some people have said to me, "what happens if the scheme is played out and
no one sends me any money?" Big Deal, so you lose $5 - but what are the
chances of that happening??
There are millions of internet users, and millions of new net surfers every
month.
Remember - read the instructions carefully, and play fairly. That's the
only way this will work. Get a printout so you can refer back to this
article easily.
Try to keep a list of everyone that sends you money and always keep an eye
on the postings to make sure everyone is playing fairly. You know where
your name should be.
REMEMBER - HONESTY IS THE BEST POLICY.
WHAT ARE 5 DOLLARS TO YOU?
YOU DO NOT NEED TO CHEAT THIS IDEA TO MAKE MONEY!!! This is the easiest
way that you can make a buck. Think how excited you'll be to open up your
mailbox day after day! Will it be $49? $122? Start making your plans,
because it can happen to you.

Extra section:
HOW TO POST TO NEWSGROUPS FAST WITH YOUR WEB BROWSER:
If you have Netscape 3.0 do EXACTLY the following:
1) Click on any newsgroup like normal, THEN click on 'TO NEWS', which is
on the far left when you're in the newsgroups page. This will bring up a
box to type a message in.
2) Leave the newsgroup box like it is, CHANGE the subject box to something
flashy, like, "NEED CASH $$$ READ HERE $$$ or "FAST CASH"!!!
3) Tab once and you should be ready to type. Now, retype (only once) THIS
whole article WORD FOR WORD, except insert your name at #5, and remove #1
off the list, plus any other small changes you think you need to make.
Keep almost all of it the SAME!
4) When you're done typing the WHOLE article, click on FILE in THIS BOX,
RIGHT ABOVE SEND, NOT WHERE IT SAYS NETSCAPE NEWS ON THE FIRST BOX.
Click on SAVE AS when you're under FILE. Save your article as a text file
to your C: or A: drive. DO NOT SEND OR POST YOUR ARTICLE UNTIL YOU DO
THIS. Once saved, move on to number 5 below.
NOTE: If you don't want to type in the whole article by hand, AND you know
how to use a plain text editor (like Notepad), you can edit the file ahead
of time, then attach it as shown in step 6.
5) If you still have all of your text, send or post to this newsgroup now
by just clicking send, which is right below FILE, and right above Cc:
6) Here's where you're going to post all 200. OK, click on any newsgroup
then click on 'TO NEWS', again in the top left corner. Leave the
NEWSGROUPS BOX alone again, put a flashy subject title in the SUBJECT BOX,
hit TAB once you're in the body of the message.
Click on ATTACHMENTS, which is below the SUBJECT BOX. You will get another
box to come up. Click on ATTACH FILE, then find YOUR file that if you did
this right, you should see your file name in the attachments box, and it
will be shaded green.
NOTE: If you don't want to type in the whole article and you know how to
use a plain text editor (Notepad), you can edit the file ahead of time,
then attach it.
IF YOU USE IE EXPLORER IT'S JUST AS EASY...HOLDING DOWN THE LEFT MOUSE
BUTTON, highlight this article. Then press the "ctrl" key and the "c" key
at the same time to copy this article. Then print this article for your
records, to have the names of those you will be sending $1 bills to.
2) Go to the news groups and press "post an article". A window will
open. Type in your headline in the subject area and then click in the
large window below. Press "ctrl" and then "v" and the article will be
placed in the window.
If you want to edit the article, do so and then highlight and copy it
again. Now every time you post the article in a new newsgroup all you have
to repeat is "ctrl" and "v" and press post.
3) That's it. Each time you do this, all you have to do is type in a
different newsgroup, so that way it posts to 200 DIFFERENT newsgroups, or
more.
You see? Now you just have 199 to go!! (Don't worry, each one takes about
30 seconds, once you get used to it. REMEMBER 200 IS THE MINIMUM. The
more you post the more money you will receive.
AND THAT'S IT!! THEY ARE ONLY STEPS!!!

That not what I need. An example:
package Math::Fraction
sub add {
$frac1 = shift;
$frac2 = shift;
...
}
now when I call it with a method (or using overloads) $frac1 is garentied
to be an object of Math::Fraction but $frac2 is not. I need to be able
to tell what $frac2 is, and simply testing if it is a reference will not
due as $frac2 could be something like Math::BigInt or Math::BigFloat for
example.

CGI & PERL are different animals. CGI is a standard method by which web
browsers and web servers can interact. Basically, CGI is a defined set
of environmental variables that can be accessed by your back-end server
script/program/whathaveyou. PERL scripts are frequently used for
interpreting, parsing--which is separating name/value pairs into the
appropriate parts, etc. PERL just happens to be very good at handling
CGI variables. CGI-capable scripts can be written in almost any
language, though. DOS batch files, Java, Visual Basic, Unix shells,
Lisp, Basic, Pascal--choose your poison.
As with everything else in life, there's more to it than this, but
this'll getcha your answer.

This is a very keen observation; CPAN has lots of nice stuff, a one-stop
place for Perl programmers. The Makefile.PL is used by MakeMaker,
which does not run on the ActiveWare port of Perl. This is probably not
so much the fault of the ActiveWare porters so much as the fact that
Windows 95 and Windows NT do not have the same rich store of development
tools as Unix. MakeMaker depends (minimally) on a working make, and
most likely also won't be happy without a shell and lots of the standard
fileutils. I wish this weren't the case, since I use Win32 quite a bit.
Also, some modules, like CGI.pm can be installed by hand; I believe they
come with instructions to this effect. CGI.pm can be installed into the LIB
directory under your Perl for Win32 installation. However, you should
examine the docs, since I think there's some other steps you must take.
I'm sure there are many modules that will install this way, but anything
with a C extension will certainly not install without porting.
Hopefully, this won't be the case for long, as some employees of Cygnus
Support have been working on a port of the GNU toolchain to Windows NT and
95. They are pretty far along, and you can find out more info on:
http://www.cygnus.com/misc/gnu-win32
When this is done, you should be able to build Perl and any extension
under Win32.
Instead of waiting for this project to stabilize, which could take some
time (especially because it's so ambitious), remember that any computer
capable of running Win95 will run Linux even more efficiently. Even if
you're low on disk space, you can cram a working development installation
into about 120 megs or less. If you just want to experiment and don't want
to repartition your drive, you can simply perform a UMSDOS installation,
which will install Linux in a pseudo-Unix filesystem under a VFAT/FAT
directory, such as C:\LINUX.
Hope this helps,

Subject: Module or script of data checking routines?
Message-Id: <5h53ab$pt2@shell3.ba.best.com>
I'm handling incoming data and different lines have to be checked in
different ways: some have to have a certain number of digits on the
line, others can't have more than a certain number of letters, etc.
I was wondering if there was a module or file of subroutines available
that had routines where I could pass the data to &checkdigits with
the range of allowable digits, and other routines with similiar
functions? I looked through the modules on CPAN but didn't see
what I was looking for.
Thanks.
later, david

You should consider reading the perlform manpage. It describes how to
use formats. Using sprintf() in conjunction with write() should do
what you need.
Hope this helps.

Exactly.

But if it was your problem and in a time-critical situation, perhaps you'd
like to be able to have some idea about which is which? Of course,
benchmarking with your own data is The Way To Go, but FWIW, I'd bet
that the [^:]: method will be substantially faster than the .*?: method,
although it won't matter much unless it's the bulk of a big loop.

How about letting perl find the paragraph boundaries for you?
perl -w00 -e 'print join "<p>", <>'

When I try it, it correctly reports the error on line 5, on all versions
of perl from 5.002 to the present. So I suspect he is running some
very old version of Perl.

I might have mentioned this before, but I'll dare it again:
Finding any reference to the ... operator in the book is close to
hopeless. I had to grep for \.\.\. in the manuals before finding it
in the book. Also, the ... operator is absent from all operator
tables, precedence tables, index etc. I almost thought I had dreamed it
(I too dream in perl sometimes) before it finally appeared in that
grep.
