Message-Id: <6io492$q2$1@news.nyu.edu>
Hey Guys. Pardon my Perl ignorance - I hail from the land of TCL/Tk, GUI
design.
In TCL/Tk you can avoid explicitly writing:
#!/usr/bin/wish
by doing:
#!/bin/sh
# The next line is executed by /bin/sh, but not tcl \
exec wish $0 ${1+"$@"}
Is the same trick possible in Perl? How do I write it? I'm about to
distribute a large program with a small piece of Perl and I need to
disociate my perl program form any path assumptions.
Thanks!

man perlrun has this to say:
Typically this is used to emulate #! startup on
platforms that don't support #!. This example works on
many platforms that have a shell compatible with Bourne
shell:
#!/usr/bin/perl
eval 'exec perl -S $0 ${1+"$@"}'
if $running_under_some_shell;
If you change #!/usr/bin/perl to #!/bin/sh it should work just about
anywhere provided that perl is on the user's path.

Unless I am mistaken, this is comp.lang.perl.MISC. Anyway, I do find it
relevant on other grounds other than the fact that it has to do with Perl;
that is, we have working proof that the Perl community does a pretty good
job of moderating itself, despite some people worrying to the contrary.

Right. It's a newsgroup for talking about a programming language. This
is not about a programming language. This is about IRC. It happens to be
metadiscussion about a forum for discussing the same programming language
on a completely different medium.
That doesn't make it on-topic here.
I ran an IRC channel for about two years. I've seen more of these things
than I can possibly count, and they are without exception exercises in
utter futility started by whiners and perpetuated because the channel ops
aren't willing to just let it drop. The only reason why I actually use
#perl at all, after having given up completely on IRC some time ago, is
that because unlike the rest of IRC most of the people on that channel
have a brain and are reasonably good at ignoring the ones who don't.
Ignoring doesn't mean perpetuating their threads on clpm.
Please let's not start the precedent of attempting some sort of rational
discussion over IRC logs. IRC logs do not produce rational discussion.
Arguments over IRC transcripts and rationality are, in fact, mutually
exclusive concepts.

I guess this shows my age. I still remember when USENET wasn't
officially allowed on the internet because of acceptable use policies.
Back when people didn't automatically assume that you had internet
access just because you could post. Now if it isn't "internet", it's
"smoke signal".

Please don't do this. Usenet is a plain text medium. vcards have no

Depends on the contents of the variables. But it's really a
meaningless question. You use eq if you want to compare the things as
strings. You use == if you want to compare them as numbers.

But you were asking us to look specifically at your code and tell you

i'm not trying to rub salt into your wounds, but doing a syntax check
is often helpful:
perl -cw my_script
it will tell you where you messed up, and often how.
additionally, the
use strict;
pragma builds good habits and keeps you from hanging yourself (most
of the time). takes a little while to get use to it, but it's worth
it.
good luck :)

Subject: Converting binary to Ascii.
Message-Id: <354FA74B.9BA32D67@ceng.metu.edu.tr>
Greetings all,
In my project, there is a part that I need to translate some binary
characters into text characters. I am using tr for that. But it seems
that it is not always working. What I am doing is this:
$_=~tr/v/O/;
$_=~tr/V/O/;
$_=~tr/|/U/;
$_=~tr/\/U/;
$_=~tr/g/C/;
$_=~tr/G/C/;
$_=~tr/p/G/;
$_=~tr/P/G/;
$_=~tr/}/I/;
$_=~tr/]/I/;
But sometimes, I get an unpredicted result (long words, etc..). Is
there a way to do the conversion with numbers? For example like using:
tr/\ascii_no_of_\/U/;
etc..?
Thanks for your help in advance!

from the perlop man page (to which `perldoc -f tr` points you)
tr [\200-\377]
[\000-\177]; # delete 8th bit
from that you should be able to figure out what you need to do.
good luck :)

Hi everyone,
I'm attempting to convince my Uni Unix administrators that I really need
a good Oracle DBI instead of the crappy one they wrote themselves. I
originally went for MsqlPerl but that fell through the floor, so I'm
wondering if there is a good Perl DBI for Oracle (other than OraPerl) which
doesn't require a million changes to a University server and which can be
implemented painlessly and quickly.
Does anyone know of such a DBI or am I really away with the pixies?

i'm wondering if you know about the DBI module and it's drivers (DBD::*).
perhaps you jsut meant "DBI" in general...
anyway, see CPAN for modules called DBI.

You could also assign all but the first 20000 entries to an array by
using an array slice [20000..$#array]. Better make sure $#array is
large enough first though.

A -s test and renaming of the old file at a certain size would do
nicely.

I know that. You know that. The original poster obviously didn't. My
lengthy response was designed to point him to the documentation, to
show him that he could have found a plethora of information about perl
and perl functions, if he was only willing to read a bit, instead of
just ask. One doesn't learn programming by asking other people to
solve one's problems. One learns by trying, and reading, and trying
again. One learns by example. In this specific case, the question was
so basic and well covered by the documentation as well as a lot of
answers to other questions in this group, that I didn't think it
deserved another example.
Besides that, his question wasn't clear enough.

I suppose that this is what you call a 'line continuation character'?
Why do you think you need one? Just leave it off. You're allowed to
split stuff over multiple lines without any special characters.

The file INSTALL has lots of tips. You can check the file in the hints

That is odd. I have built perl 5.004_04 on both Solaris 2.5.1 and
2.6... Which are you using? Did the whole configuration go right? What
is the C compiler you use? What platform did you tell configure to
use? Have you tried letting configure do its own work with sh Configue
-des?

Maybe not so obviously :)
It looks like you might have misconfigured perl... Try running
configure with -des, as mentioned in the INSTALL file, and let it make
its own guesses. If that doesn't fix it, we can have a better look at
it.

More than possible. It's been done. LinkScan is a perl program
that does it. Don't recommend you writing it yourself. LinScan
has thousands of hours of development invested in it.
Our studies show that most websites have significant
problems. These include up to 30% of the external links
being broken, missing files, orphaned pages, and faulty
mailto addresses. Yet most webmasters are blissfully
unaware that they even have these problems. Why? Because
they don't regularly check their sites for these problems.
In fact, in many cases, they have never, ever checked for
these problems. The reason is it's too time consuming and
difficult to do manually.
The solution is to use a link validator to test every link
on your website. LinkScan is the most thorough and fastest
quality assuarance tool available. It runs on any Unix or
NT server and with virtually any browser on any platform.
LinkScan has worked successfully on websites with over 250,000
pages and more than 50,000 external links. It checks external
links at a rate exceeding 40,000 links per hour. LinkScan is
essential to a professionally managed web site, and to those
that want to just look like they are professionally managed.
And you don't need to know Unix to run it. It sets up all
directories and permissions and builds your configuation file
automatically. Most users have it running in minutes.
You can check your entire website today by downloading a
free evaluation copy of LinkScan. The file is less than
240 KBs so it will only take a few minutes.
Don't get caught with your links down. Don't let your visitors
think your site sucks! Fix those broken links today. Download
your free evaluation copy now at:

Thanks for the suggestion. I was debating whether to be more
specific, or not. I chose "not".

Not from what I can tell. There's TONS of information files,
sample programs, books, etc. And most of this stuff is useless when
the platform is Win32Perl. I'm spending more time wading through
stuff I can't use, than I am in doing my real job (writing
documentation for plasma etching equipment.)

Concurrency is not that important. The identifier data is being
submitted within the forms data. The sequential names are just to
prevent the script from overwriting an existing file before it's
parsed by the PC application.

It's not clear whether you expect the Perl users of Silicon Valley to
consider themselves part of your group or not, because you mention SF
by name, and the "bay area" is pretty big. I know that every time *I*
go to Silly Valley, *I* end up partying every night with a bunch of
crazed Perl hackers. So the informal groupings have already taken
shape.
So, are you 3 in the silicon valley area, or something that takes more
than an hour to drive from there (like The City)?

Subject: Telnet question
Message-Id: <354FAE86.C1E5398B@holly.colostate.edu>
Sorry to post this here, but I know the intelligence of the net is
in this group. :-) I made a "talk" server, which communicates with the
telnet program, using sockets. The problem is when people type, they
SEE what they type on their side (AKA Local echo) And this messes up the
formatting. ie:
John: Hi there!
What's up, John?
Bill: What's up John?
It gets worse.
So, since telnet is the interaction program, I can't do any magic
Perl on the client side. So my question is how do I turn off local echo
on their side? Telnet says it has a local echo toggle, but I can't get
it to do anything. (I should rephrase that, I CANT do anything from my
side, but I am trying to come up with INSTRUCTIONS for the user to turn
off their local echo...but I don't know how ;) )
Any help or insight would be greatly appreciated! Any Tori fans out
there? (You'll know what I mean!)

Message-Id: <354F9BB9.BE6691D3@fa.disney.com>
I cannot get Tk400.202 to build on AIX. When running the perl
Makefile.PL it just hangs. I have tracked it down to the following sym
link that is part of the distribution:
1 lrwxrwxr-x 1 cmihaly prodctn 35 May 5 15:51 Tix ->
/home/road10/free-sw/tcl/Tix4.0/src
This is in the distribution. It causes AIX to hang and to eventually
get NFS timeouts. Of course, we have no /home/road10.... TK400.202 was
supposedly the last official non beta release of TK. How do you fix
this link? Strangely,IRIX didn't complain about this even though the
bad link is there also :-)

I was about to blush and apologize, but then I checked
http://www.perl.com/CPAN-local/doc/FAQs/FAQ/PerlFAQ.html
which is my usual route into the Perl FAQs. Supposedly
this is one large HTML file of the FAQs, right, convenient for
searching.
Searching for FindBin finds nothing...
Searching for other likely things doesn't help.
And, yeah, I have read the entire FAQ, but I daresay I don't
remember it all.
I am sure that the information is in there somewhere, but I can't find it.
This reminds me more and more of LISP, or do I mean Adventure:
a maze of twisty little passages...
Joshing aside, *which* FAQ should I be reading?

Subject: Using perl Tk:: versus HTML forms for GUI front-end
Message-Id: <354FAC09.2902@flash.net>
I need to develop a light duty user interface for a perl-based
application, and am looking for comments on whether people would suggest
using Tk:: or HTML forms and cgi....
The application is not huge, and basic line input, select boxes, etc are
all I need. The interface is fairly procedural, and not too complex.
Initially it will run standalone on windows95 machines, but may used in
an intranet in a LAN, or eventually become a "real" web application.
I'd be interested hearing what people have to say about the complexity
of coding the TK interface versus building HTML-based forms for the GUI.
My first guess is that the interface is easy to build with HTML, but I
have to install local webservers to handle the cgi requests (even if
everything is local on a standalone machine) which looks like it might
get a bit "involved."
comments?
thanx,
Dan
