This isn't strictly speaking, true. Perl doesn't actually localize the
match variables so much as play some interesting tricks with data
structues attached to the optree. (Try playing with regexes and recursive
subroutines and you'll see what I mean) It acts like you have a local copy
most of the time, but not always.
It's best to snag your match memory variables as soon as possible and not
count on $1 and friends maintaining useful data for very long.

Subject: Activeware Perl and Windows 2000
Message-Id: <8io22d$f1j$1@mawar.singnet.com.sg>
Hello,
I used to run my perl scripts Win95's command prompt to check out that they
work before I upload them to my server. A typical query would probably be:
C:\Scripts>perl main.cgi domain=www.here.com idnum=4278
With Win95, my script will be able to get the variables, either directly
from the $ENV or via one of the parsing routines.......
However, this doesn't work on Win2k! the variables don't seem to show up in
Win2k.
If I upload the script to the web server, it works. Is this something to do
with Win2k's command prompt? It's cmd.exe, not command.com.......
I'm running the latest download of activeware's perl 5.6, on windows 2000.
Thanks for any assistance!

A wise tactic.

Sounds as if you're using the CGI module. Good!

Sounds as if Win2k changed its way of doing this. But if you're using the
CGI module, you should be able to type the name=value pairs, when
prompted, at the console. Doesn't this work as documented?

Could be. Perhaps you should search for the docs, FAQs, and newsgroups
about that program or your system.
Good luck with it!

That would be the null filter. Of course, that's especialy weak
encryption. (I'm poking fun at your request. Do you see why? :-)
I recommend hiring a real cryptographer. Else you'll likely end up with
snake oil.

Not per se, not at all. Per se might imply to some that HTML

How a file looks is not the determining factor where programming
language or not programming language is concerned. HTML
(Hypertext _markup_ language) is a simple formatting method.
It is just like adding nroff/troff markups to a plain text file
that will output pretty text with silly typeface. It is not,
however, programming.

You need to study what a web browser does just a bit more.
Its not pretty clear to me that a browser is directed by
an HTML file.

Right. But if you can get a core dump, you can use a debugger like gdb to
see whether you were in a blocking system call (like flock), at least. And
if you have a debugging version of perl (compiled with -DDEBUGGING), there
may be other options available to you. There ought to be a way of finding
your current file and line number, but I can't see what it is.

That ought to be possible as well, but I can't say whether it is or not.
One thought worth persuing: Could you have a "neverending" regular
expression, by chance? See Friedl's book "Mastering Regular Expressions".
Here's a possible debugging tactic: Have your program append "got here"
messages to a logfile, including their current line number and anything
else you might wish to know. When one hangs, you can read the last message
to learn where it was last seen alive.
Good luck!

Since -s uses stat() internally, that's not surprising. :-) It's "merely"
more convenient syntax. I put "merely" in quotes because it's much more
easy to read, write, debug, and maintain. If you use a slice on stat(),
your maintenance programmer is more likely to have to look up the stat
docs to see which item you're using. But -s is more likely to be in their
memory.

Someone deleted the file or directory before you got to it. There are too
many symbolic links leading up to the file or directory. The file or
directory is on a no-longer-mounted filesystem. See your system's stat(2)
manpage for more.

Let me step in at this point, and point top MJD's module and article:
http://www.plover.com/~mjd/perl/Identity/index.html
It is based upon the fact that code in a hash or an array index, even
inside a string, is always executed.
%word = ( 1 => 'one', 2 => 'two', 3 => 'three');
print "The sum of $word{1} and $word{2} is $word{1+2}.\n";
Ergo, make a tied hash which applies a funtion to it's "key", returning
a string, and you can calculate inside a string -- even preformat the
result. Oops, I've spoiled it. That was the whole secret. ;-)

I hope I did this correctly. The reason I tried to answer your timing
question when Mr. Rosler did not is that I'm trying to learn how to use
the benchmark.pm that Larry so nicely pointed out.
If I've blown it, I'd be happy to have somebody point out how I should
have done it.
It looks like your first (index, substr) method is faster than your
second (sprintf).
--------------------begin code--------------------
use benchmark
$s1 = '$_ = ${\substr ($string, 0, (index ($string, ".") + 3))}';
$s2 = '$_ = ${\sprintf \'%.2f\' => $string}';
$string = "1234.56789";
Benchmark::cmpthese(400000, {'n1' => $s1, 'n2' => $s2});
--------------------end code--------------------

Perhaps the ExtUtils::F77 module might be of help here - it
tries (depending on the system) to figure out how to link
C programs with fortran subroutines. See, for example,
http://theoryx5.uwinnipeg.ca/CPAN/data/ExtUtils-0577/F77.html.

That might get you the directory where the perl script
itself lives and it might not. Moreover, that's not
the working directory.
I suspect, however, that what you want is, indeed, the
directory wherein the perl script lives since you probably
have your module in that same place. In which case you
want FindBin:
use FindBin qw($Bin);
use lib "$Bin/../lib";
# Or, in your case, perhaps
use lib $Bin;
See the docs for more details.

Except when taint checking is enabled, '.' is already included in the @INC
search. When taint checking is enabled, relative paths like '.' are
disallowed. So I don't think this line of code is useful, except in the
rare case that there's an archname subdirectory to the current directory.
Am I missing something?

Sounds like you want BSD::Resource.

I'm sending you a copy of a posted message. But, in general, you shouldn't
post to a newsgroup you don't read. And there are Usenet archiving
services (like www.deja.com) which can let you read replies to your
message quite easily - although Deja hasn't been itself lately.
Cheers!

Message-Id: <8ins7d$6vb$1@nnrp1.deja.com>
Hello, I'm fairly new to this whole Usenet thing, so if I commit some
grave travesty of Usenet etiquette, please forgive me. Oh yeah, and I
want to apologize for the little advertisement that will probably
appear at the end of this post.
I need to get better at Perl. My situation at work is that I am the
only Perl developer, whilst everyone else is using all this jsp and ejb
stuff. It's very hard for me to confirm my work, because there's no
one at my workplace who knows a lot of Perl, and I don't know a lot
myself.
Suggestions for books I should read, or seminars I should attend (in
the Boston area), or if you are willing to tutor (again, in the Boston
area), then please respond to this post.
Thank you,
Ohako

You have made several bad decisions. The first was posting before
lurking. It is always wise to read posts for some many weeks before
making your first post. This will help you get a handle on the way
that the group works. You should also check the newusers newsgroups,
such as news.newusers.questions.

Best bet is to read. Perl comes with lots and lots and lots _and lots_
of documentation. If you haven't read it yet, do so now.
$ perldoc perldoc
When you have a need for assistance, check on something like Deja
to see if somone has already had the same problem, and see what the
solution was. If you don't see a solution posted, a polite email to
the poster asking how s/he solved the problem might do the trick.
After you have exhausted all available resources, and still not
found the solution, boil your code down to the smallest bit that
displays the problem, and post here. In situations like that,
you are sure to get help.

I think we can forgive that but it isnt really a very good news client.

Read this group. Read Uri's page <http://www.sysarch.com/cgi-bin/perl_books>.
Read <http://www.perl.com>, read the enormous set of documentation that comes
with Perl.

You are a very lucky man. The Boston Perl mongers are near you. Check out
<http://boston.pm.org> for more. No I dont know what the graphic is all
about either but hey they're 2500 miles away from me why should I care ;-}

Get "Learning Perl" to learn the language, and get "Programming Perl"
and "The Perl Cookbook" for reference. Avoid this newsgroup; it's a
very poor place to get help. Very few people here will take the time
to help you, unless you consider admonitions to RTFM helpful.

1. Reading the manual is the best place for help. You accomplish
2 things: You solve your own problem _and_ you learn how to
solve future problems.
2. If this group is so _un_helpfull_, why are ya here? It must have
at least one good point, eh?

I used to get this message all the time when building software. Turns out it
was an issue with NFS. The filesystem I was building on was NFS-mounted from
another system, and the clocks were out of sync. Try building the module in
a local filesystem (try /tmp) and see if that solves the problem. If it
doesn't, then at least you've eliminated one potential solution. :-)

So it's only shite programmers who publish their code and useful
scripts for free on the many good resource-sites throughout the
Internet? ;-)
Personally, I'd give 5 stars to those quality programmers who do so.
By sharing code, you share knowledge.

True.
