Subject: A Newbie needs HELP!
Message-Id: <7j3dlh$5buk$1@newssvr04-int.news.prodigy.com>
I have to admit that I know nothing at all about Perl or other programming
languages. However, I've come to realize that to accomplish certain things
in HTML, you really have to use a script like Perl. So I fully intend to
begin learning Perl, but meanwhile I'm stuck with this problem.
Rather than include the HTML in this message, I've posted a page on the web
which is an example of what I'm trying to do. You can look at it, and view
the HTML source at:
http://members.aol.com/bayvideos/example.html
What I want to do is to arrange all the listings on the page alphabetically
by (in this case) the name of the auction. The problem is that each auction
has a description, and I have to make sure when the HTML is rearranged, that
the matching description and anchor are moved together with the name. I've
got about 300 HTML files arranged exactly like this one (and many of them
much longer), so you can see why I don't want to do it manually!
I don't know if this is difficult to do with Perl, or if it's a breeze for
someone who knows the language, but I sure would appreciate any
help/suggestions/advice you can offer.
Many thanks in advance,
JJ

Subject: Re: system() question
There are a lot of reasons, many of which get repeated over and
over again, many of which don't. Some of the reasons you hear a lot
are: Questions are incoherently phrased. Questions have the form `my
code doesn't work' and don't include the code. Questions include the
code, and it's 200 lines long, and comp.lang.perl is not a debugging
service. Nobody knows the answer to the question. The question is so
badly punctuated that nobody can bear to read it. Questions aer
written by a non-native speaker of English and the native speakers who
are trying to understand it can't. (That's a shame, but it does
happen. I often wish that these people would post in their native
languages. I'd love to see more discussion in languages other than
English. Some Dutch guy tried posting all his comp.lang.c articles in
Dutch a few years ago, and all the Americans flamed him. How
humiliating for me!)
Apart from these oft-mentioned reasons are many others that are
not so often discussed, because anyone who tries to bring them up gets
flamed. But it's the truth: I know the reason I don't answer more
questions is because so many of them questions are so damn stupid.
They're stupid in a lot of different ways, but they're still stupid.
I don't want to suggest that that's why your questions go unanswered.
I don't know what you're asking. No doubt the reason your questions
go unanswered is because they're so deep and interesting that nobody
really knows the answer.
The most common stupid question is the one from someone who has
some high-level problem that they need solved. They have an idea that
they'd like to do it in perl, and they don't really know perl. So
instead of learning perl, they post to comp.lang.perl.misc.
Now don't get me wrong. I don't have any problems answering the
questions of someone who's trying to learn perl. I love THOSE
qusetions. But these people don't seem to be asking useful questions
for that.
Today, for example, I saw a question from a guy who wants to get a
list of hostnames out of nslookup. `How do I do that?' he says. And
it's hard to know what to make of that. What does he mean? Does he
not know how to open a pipe? Is his `open' command failing? What's
going on here? I can't give a useful answer without understanding the
problem. Having your `open' fail is a problem. Wanting to list
hostnames is not a problem; it's a desire.
Here are some similar questions that would have made more sense to me:
1. ``I'm a lazy asshole and I can't be bothered to learn to
program myself, but I know if I post here you'll give me
something for free.''
(OK, fair enough. At least I can send him a rate card.)
2. ``I'm trying to use `open' to talk to nslookup, but...
...here's my code; what's wrong?''
(Good question.)
3. ``I know perl has a `system' command for running programs,
but I can't see how to get my commands into nslookup
once I have run it.''
(Good question.)
4. ``I'm trying to use `getprotobynumber' to talk to nslookup...''
(Good question.)
See, I'm not just biting people's heads off, here. #4 is a good
question, because it gives me something to work with. OK, he has a
very weird idea about interprocess communication, but that's
ignorance, and that's what we're here to correct. He doesn't know
about `open'; I can refer him to the manual.
Here's another example: Some guy wants to assemble a list of email
addresses . ``How do I do that?'' he wants to know. Well, duh. Get a
big pad of paper and read news for a couple days and write down all
the addresses you see. Problem solved. What's it doing in
comp.lang.perl?
Oh, you wanted to do it in perl. Well, I guess I'd open a socket
to the NNTP server and send it some XHDR commands for the `From'
lines. But that's not Perl; you could do that in any language. I
could do it in Bourne Shell for you if I'm allowed to use a little
external thingie to handle the socket parts for me. What's it doing
in comp.lang.perl?
Oh, you wanted us to write the program for you? Wait, let me send
you my rate card.
Someone posted yesterday asking how to get the data from a file
where the start and end of the data is marked by keywords. Same thing
going on here. ``Well, here's how you solve your problem: First you
go take an introductory class in programming and learn to write
programs in some language. Then you go to the bookstore and buy this
book by Wall and Schwartz, it's really good. Read the book carefully
and try out the examples. Then if you still have general questions
like `How do I do this' instead of `I thought that this code would do
X but instead it does Y' you hire a professional to write your program
for you. Or you could just skip right to step 3. Want my rate
card?''
The worst stupid questions are the ones that come from people who
have no business asking them. The most perfect example of this that I
could have imagined was in comp.unix.questions a couple of years ago.
Some guy came and asked how you could tell if a file is a hard link.
My jaw flapped open and it's stayed open since then. I couldn't have
been any more stumped if he'd asked why Bodhidharma came from the
West. What do you say to this guy? Do you tell him the truth, that
all files are hard links, that even symbolic links are hard links?
He's not going to understand you; you might as well keep your mouth
shut. Do you tell him the truth, that the answer won't do him any
good because he doesn't know what a hard link is, so why did he bother
asking in the first place? No, that'll just make him mad. I followed
that message for the next couple weeks, and nobody said anything.
What could you say? The guy had no business asking the question and
no use for the answer. Maybe the right answer would have been to cut
off his finger or something. I dunno.
Some questions get ignored because they're boring. Someone asked
today how to compare two variables (I assumme he means the contents of
those variables) to see if they're exactly the same. You've gotta be
in an awfully good mood to take the time to answer that. Maybe
someone will. Maybe I will.
If I answer that one today, maybe he'll be back tomorrow asking
how to check to see if two variables contain different values. Maybe
I won't. What I find incredible is that if you tell these people to
go read the manual and come back in two weeks, you sometimes get
jumped on for not being helpful to beginners. Bah. If everyone told
these people to go read the manual, they'd eventually figure out that
that's what you have to do ,and then I wouldn't have to spend so much
of my life dealing with incompetent programmers.
Some questions are logically nonsensical because the querent
thinks they know more than they do. A lot of these have the form
``How do I use X to accomplish Y?'' There's nothing wrong with this,
except that sometimes X is a chocolate-covered banana and Y is the
integration of European currency systems. I always get stuck on
these, probably because I can't get rid of the idea that the person
really has a good reason for wanting to use X. I know a half-dozen
easy simple ways to accomplish Y, but I can't imagine what X has to do
with it. This is a problem for me in my day job, too. Clients are
always saying to me ``We want to use product X to do multimedia
development on the world-wide web,'' and all I can think is ``Well,
gee, what would you want to go and do that for?'' Sometimes it turns
out that they want to do it because they want to impress the
manufacturers of X, and I don't work on those jobs.
The flip side of this is a questions like ``I want to accomplish
X, but I don't want to use Y. What can I use instead?'' Which,
again, is sometimes reasonable, and then sometimes X is closing a
filehandle and Y is the `close' function.
The questions I like the best are the ones that go like this:
``I want to accomplish X.
I thought that the following code fragment would do it:
...
But instead it does Y.
Why is that?''
This one is also pretty good:
``I want to accomplish X.
I thought I might be able to use facility Y.
But Y doesn't seem like it's quite right,
because of Z.
What should I use instead of Y, or how can I overcome Z?''
When I ignore these, it's usually because I don't know the answer.
There were an awful lot of them today. It makes me very happy.
There you go; a 160-line dissertation on why questions go unanswered.
Now don't let me hear you saying nobody ever answers your questions.

You will need to build a Perl which will support dynamic loading - however
because you dont make it clear what actual version of SCO you have I
cant tell you whether it is possible :
jns [pigment] $ uname -X
System = SCO_SV
Node = pigment
Release = 3.2v5.0.4
KernelID = 97/05/07
Machine = Pentium
BusType = ISA
Serial = 4EL020857
Users = 5-user
OEM# = 0
Origin# = 1
NumCPU = 1
That one will build a dynamic ELF binary
sys0001 [figment] $ uname -X
System = figment
Node = figment
Release = 3.2v4.2
KernelID = 93/04/28
Machine = i80486
BusType = ISA
Serial = ltd001605
Users = unlim
OEM# = 0
Origin# = 1
NumCPU = 1
That one wont ;-{
I beleive that for those versions of SCO that do support dynamic loading
the 5.005.03 release of Perl has an updated hints file that will aloow
this. Alternatively you could check out :
<http://www.sco.com/skunkware/src/htdocs/perl5.004.04.html>
Which has details of how to build an earlier version - I have actually
got this to work with 5.005.02 as well and succesfully built DBI from
these instructions.

Actually, the problem was more that you've been using quotes within quotes.
In theory you should use quotes in hashes, like in $forms{"stuff"}, because
otherwise
perl complains it found a bareword that could be used for future keywords
(or something),
but in hashes it would assume you meant a literal. So $forms{"stuff"} is
really the same as
$forms{stuff}, and is correct perl...

You cant just install a module like GD like that. It has binary elements
that need to be compiled.
However all is not last. You can install GD simply by typing:
ppm install GD
at your command prompt (assuming you have a network connection and a
half way recent ActiveState Perl).
If you need more information about PPM then you will be able to find
more in the documentation it installed in your start menu.

If $afile is actually a filename I wouldnt expect the prepare to do
anything. I would also expect that you would have to extract your
results first then write them to a file in the standard way, independent
of the DBI interface.

1) Add -oi command line option to sendmail invocation.
2) Check exit code returned by sendmail (close exit code)

It disables special treatment of single dot lines
- single dot line usually means end of message,
(all lines starting with a dot are also rewritten)

($returncode=close(MAIL))
die "sendmail exit code: $returncode" if $returncode;
die "undefined exit code" unless defined($returncode);
Some sendmail installations return exit code 75 when the message
is queuened (to be delivered later)
Another option is to run sendmail in verbose mode (-v)
and capture the output (stderr I think)

Subject: scalar question: how can you tell the difference between numbers and strings?
Message-Id: <7j3dvj$9c8$1@flotsam.uits.indiana.edu>
I can't find the answer to this question anywhere. Can you help?
I have an array that contains a bunch of integers and strings. I want to
iterate over the array and find particular integers and strings. If I'm
looking for a string I have to use 'eq' - but if I'm looking for a number I
have to use "==". What do I do if I don't know what 'type' one of the
arguments is?
I've noticed that if I read a line from a file and then split the line into
an array, that numbers in the file "become" numbers and non-numbers "become"
strings. For example, if I read the string "57" in from a file, it becomes
the number 57 instead of the string "57". Am I missing something here? Is
there a way to know the type? Is there a way to "force" the type?
Any light you can shed would be appreciated!

Correct.

No you don't...
Did you ever try using 'eq' with numbers?

How can you tell that "57" becomes the number 57?
Usually perl knows how it should treat strings/numbers (let's call them
scalars). For example,
consider following code snippet:
$a='57';
$b=$a.2; # Gives $b=572; $a treated as a string
$c=$b+2; # Gives $c=574; $b treated as a number
$d=$c.2; # Gives $d=5742; $c treated as a string

Subject: Using DLL functions in Perl
Message-Id: <375524ae@news.uk.ibm.net>
How can I call a DLL function in Perl?
I don't have any source code from the dll (it's an encryption/decryption
algorithm that has to stay secret, even from me :-( ), but
I know the arguments to pass to the function.
I'm using a Win32 platform.
Any suggestions?
Thanks,
Vincent

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.
]From: Russ Allbery <rra@stanford.edu>
]Date: 21 Sep 1998 19:53:43 -0700
]Subject: comp.lang.perl.moderated available via e-mail
]
]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
