You can do this with the LWP module, from CPAN. Hope this helps!

To make his way work, just make it a bitwise and instead of a logical one...
print $number & 1....
instead of
print $number && 1....

You can get the words from those strings by using split. Is that what you
need? Hope this helps!

You want to "split", but Perl's "split" isn't appropriate in this
case ... what you need is simple pattern matching:
($var1,$var2) = ( $var =~ /(\d\d\d)(\d\d\d)/ );

I haven't tested this code, but maybe it will work for you.
@sorted_dates = sort by_date @dates;
sub by_date {
$b->kissing <=> $a->kissing or
$b->cuddliness <=> $a->cuddliness or
$b->cuteness <=> $a->cuteness or
$a->neediness <=> $b->neediness or
$b->intelligence <=> $a->intelligence or
$a cmp $b
}
Then again, maybe you should use a Date module from CPAN. Good luck!

as an exercise, have your junior programmers write their own URLEncode
and URLDecode routines, based on what they know (or even what they can
divine from the RFC's). i think you'll find some get it right, some
come close, and other simply don't know where to begin.
or do you think that this is not an integral part of CGI programming.
oh sure, it's been done over and over to get the fastest, most generic,
most terse yet readable snippet possible, but without it you have
CGI-programming-minus-URL(En|De)coding. you have merely given your
programmers a subset of CGI programming.
furthermore, do they know the difference between a GET and a POST,
or has that already been taken care of for them:
CGI-programming-minus-URL(En|De)coding-minus-GET-minus-POST
do they form their own, non-parsed headers:
CGI-programming-minus-URL(En|De)coding-minus-GET-minus-POST-minus-HTTP-Headers
boy this list is getting long, and the subset is getting small.
so here is a venn diagram representing what i see from your
statement.
/---------------------------------------------------------\
| |
| CGI programming |
| |
| /-----------------\ |
| | what your jp's do | |
| \-----------------/ |
| |
\---------------------------------------------------------/
maybe they even do things outside of CGI programming, but
to make the claim that "CGI scripting is trivial" based
on what your junior programmers do is obviously not correct.
hope this doesn't come off as too aggressive, i am just
attempting to vigorously defend my job as non-trivial, and
yes i do refer to my job position as a CGI programmer. i
spend my days working on a CGI application which interfaces
with an oracle backend, and consists of over 200 separate
scripts, which can be called in a multitude of different
ways. there's a need to keep state to avoid hitting the
database on every transaction, there's customization for
different clients with only one master script, there's
dynamic question creation and verification based on
database results and much much more.
and, to give the original poster a useful answer, i normally
charge $50/hr for "advanced PERL CGI scripting".
thank you for your time,

I think i'm stuck in the middle on deciding which is theft and which is
good corporate procedure :-)
I'm in highschool and have known perl and its internals quite well in the
last 5 years. I find it quite... distasteful... that some of my peers are
taking "jobs" to write html pages and get paid $20+/hour. That's a rip-off
to the companies fuck... it's only worth minimum wages. I also have several
friends who "know" perl. But their scripts are unwieldy, large, and cost
more to maintain then to actually use. So, from this point of view, i do
realize that writing professional code (as i make every attempt to do)
is worth the large price to the company. But i don't charge it.
I have ANOTHER set of friends who choose to do the "to-your-home-pc-fixing"
and they charge like $50 a shot sometimes and all they do is run one of
several anti-virus programs... or use a boot disk and change config.sys...
wow... check out those skills :-) Yes... for the home pc user who doesn't
want to think they they goofed up, so by paying someone big bucks to fix
their computer they have an excuse for not being able to fix it themselves.
(The computer was _really_ screwed, so i paid a professional $50 - Yeah right)
But what is a professional? If the only reason costs are so high is because
of all the amateurs in existance.... and the amateurs all claim to be
professionals and ask for the money... hehehe it's a no win scenario for
the companies so they just take a shot and ditch out the money. I find
this almost as close to theft as say... bulk e-mailers stealing network
bandwidth.

Hello all,
I've been searching around quite a bit for cflow (preferrably) and/or

code that can be removed.
Does anyone have, or know of, tools like this for perl5??

Subject: Postgres and Perl/Pg: How to get a hash of all elements of a tuple
Message-Id: <pem-2511970956140001@ganges.lit.cwru.edu>
I am bringing up a system in Postgres SQL and interfacing with a Perl
script using the Pg library. One of the things I'd like to do is create a
hash for a tuple where the key is the column name and the value is the
data value. This seems to be a common enough thing to want, but all of
the documentation for Pg seems to lead to only one-at-a-time access to
columns. So something like this is required (assuming I have the result
of an exec() in $result):
my($tuple_num);
for ($tuple_num = 0; $tuple_num < $result->ntuples; $tuple_num++) {
my($field_num, %record);
for ($field_num = 0; $field_num < $result->nfields; $field_num++) {
$record{$result->fname($field_num)} = $result->getvalue($tuple_num,
$field_num);
}
##
## Do something with %record
##
}
This doesn't seem very efficient -- especially if the library has to send
a request to the database for each field value. Is this the only way to
do it? ... or am I missing something in the documentation?
Thanks in advance.

Hello it's me again
I originally posted this question under anothers email address because I

What I don't understand is why I was pointed toward another newsgroup when I
asked how to do some client stuff in perl.....granted I didn't pepper my
post with references to perl, but that was because I figured that if I post
to comp.lang.perl.misc...............it would be understood that I was doing
this in perl.
Is it that no one has done this? Is it that no one has done this in perl?
Is it that that other newsgroup can answer the question in perl as well?
I really really hope I wasn't pointed away because I didn't mention perl in
my post some minimum number of times.

use File::Copy;
and you can copy 'foo' to 'bar' with
copy('foo', 'bar');

No. Making a module which can do this will almost certainly earn a place

You're referencing the global arrays @a and @b here; that's not what you
want. I think you mean to use arrows, to use references: $a->[1], for
example, instead of $a[1]. Hope this helps!

You may have a perl that doesn't allow dynamic loading of modules. I was
just bit by this yesterday. Try this to see if you have the same
problem:
perl -we 'use IO::Socket;'

Subject: Variable Pattern Options
Message-Id: <347B403A.500F@gsao.med.ge.com>
In a Perl script, I'd like to have the following statement:
@matches = ($lines =~ /$pattern/$options);
However, the compiler will not allow me to use the $options variable.
I am using Perl version 5.004_01. It has no problem with using
a variable for the pattern, but chokes on the variable for the
options. Why can't I do this? I'm trying to write a UNIX script
to perform grep-like things in Perl, and need to have dynamic
options in pattern matching.
Thanks,
Greg

Administrivia:
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.
