Subject: Chdir (cwd) of shell with perl Script
Message-Id: <373D8E51.5E63B335@rbg.informatik.tu-darmstadt.de>
Hi,
I'm trying to write a perl script, that I call from my csh with a
abreviation
for a deep nested directory as parameter, and after termination the csh
current
working dir should be the meant directory.
The problem with this simple task seems to be that changes done with
chdir or system "cd " are only temporary while the execution of my
script.
Is there a possibilty to impinge on the cwd of the shell that calls the
script using a perl command line option or something else?
Thanks a lot for your time spent answering my question

That's the theory behind having all the READMEs extracted as plain text.
The trouble is that most modules don't have much useful information in
their READMEs.

: Can you add a function (a complement to exists() ) that does it?
I assume you mean "complement" in the sense of opposite?
If so, then such a function is not related to exists() that way.
The proposed function is about a hash (the aggregate).
The exists() function is about a key in a hash
(a part of the aggregate).
Anyway, such a function does exist, but it is spelled with
two keywords, as shown in the referenced FAQ:

No you wouldn't.
You would have to look at one of the places where you *said*
you would look, "part of books that talk about associative arrays".
The books you have selected are your business. If they have errors
or omissions, you contact the author or publisher, not the newsgroup.
The standard Perl docs are shipped with the perl distribution. If
they have errors or omissions, you contact the newsgroup. Or even
file a bug report against the defective docs (but you better do
a _thorough_ search of the existing docs to make sure that what you
want added isn't really already there).
Changing Perl (and perl) is a big deal.
It might break something else.
It might take lots of coding to accomodate other features.
It will consume some of the precious volunteer time available
for changing stuff, taking time away from adding new things
rather than just a new way to do something that can already
be done.
Suggesting changes to Perl/perl should not be taken lightly.
There is a pretty easy trail through the Perl docs just as they
stand for finding the answer (2 answers actually) to your original
question.
"How do I find out the number of elements in a hash array?"
1) search for "hash" in the questions in the perlfaq*.pod files:
perl -ne 'print "$ARGV: $_" if /^=.*hash/i' perlfaq*.pod
2) read the 17 questions that are found. Notice the one that
was quoted in this thread. Read that FAQ.
3) since that FAQ mentions the keys function, you read about keys.
4) answer #1 is in the second sentence.
How long would that take?
Maybe 5-10 minutes?
How long did it take to get the answer by posting to Usenet?
You are not being sufficiently lazy and impatient :-)
Or, you go read about hashes as you said you would.
Perl's data types are discussed in the aptly named perldata.pod :-)
wherein it says:
"If you evaluate a hash in a scalar context, it returns a
value that is true if and only if the hash contains any
key/value pairs."
So you can write your own entries() function 2 ways, and not
give up more useful things that p5p could spend their time on.
-------------
sub entries1 {
my %h = @_; # better and faster to pass a ref to hash instead...
return scalar keys %h;
}
sub entries2 {
my %h = @_; # better and faster to pass a ref to hash instead...
return scalar %h;
}

Message-Id: <7hjvsn$9gh$1@news1.cableinet.co.uk>
Hi,
My goal:
Instead of passing a file name to a program for it to parse and execute, i
have a program work
in the same fashion as the shell:
#!/usr/bin/ksh (however ksh would be my own program)
I'm not trying to rewrite a shell, just a simple program to handle the input
from the
remainder of the file. As you know, the #! instructs the shell you are
using to
pass the remainder of the statements (lines) that follow to your
interpruter.
Does anyone know how the shell interacts with a program in 'C'?
for example, how do i have myprog pick up what's being passed... i've tried
pipes and even stdin.
eg:
#!/usr/local/bin/myprog
directive 1
directive 2
Neil.

I am pretty sure that shebang lines are a feature of the

>From another viewpoint, what Tom is doing is "push" delivery as opposed to
"pull". For me as a MacPerl aficionado it's valuable - the MacPerl
distribution is static, and while a new release is expected, the current
one has been around for a while. Updates to docs frequently are stll
relevant, even though the current MacPerl base is 5.004, and not 5.005_x.
When he puts the stuff out there, "in my face", I not infrequently read
it, and think "Ah hah, this is new".
Case in point - I am also a CPAN tester, and I port and build modules for
MacPerl (see http://pudge.net/mmp). If it wasn't for updated docs coming
out, I might not be aware of the qr// regexp operator in 5.005, and how
that can pose problems in trying to make modules available for a 5.004
system. (This is a bit of a strained example, as I also run the latest
5.005_x stable release on MkLinux, and so I knew about this particular
feature by reading the Changes files, but hopefully you get my point).
Yes, I could get the new docs in an active way. But this is "in my face",
as I say. It helps this developer.

Not such a good idea, I think. The 'diagnostics' module is large and
rather slow to load. The information it provides is identical to that
produced by
perldoc perldiag
You forgot to send the browser the HTTP header that tells it what to do
with the data it receives.
print "Content-Type: text/plain\n\n";
> my $input_file = "text.txt";
> open(INPUT_FILE,"<$input_file") or die "Can't open file $input_file:

Keeping in mind that this diagnostic will go to STDERR, which may not be
accessible to the programmer or the user.
I prefer to write such diagnostics directly to STDOUT, while others
recommend this module:
use CGI::Carp 'fatalsToBrowser';

Or whatever behaviour one might consider appropriate - if you had even
spent a few seconds looking at Perl code you would have known this.
But of course it is a prerequisite of the troll that they have no

#!/usr/bin/perl
use IO;
$i=1;
print "Content-type: text/html\n\n";
print "<html><head><title>Test Running CGI...</title><head><body>\n";
while ($i<=10) {
sleep(1);
print "This is Line number $i <br><script>self.scrollBy(0,100)</script>\n";
$i++;
STDOUT->flush;
}

Why is this a troll?
I think the man is in uncharted waters when he states that an object
should be able to consist of more than just a reference, since everything
is a reference when it comes right down to it.
But a fixed name for an object constructor ('new') is a feature of C++ and
Java, for example. Why should Perl be defiantly different?
More to the point, what's wrong with having a discussion over the issue?
Just to put my 1.5 CAN cents on the table, I like the ability to call a
constructor anything, because sometimes "new" is not intuitive. But that's
just me.

You mean that there are still people without this-

Also the position as Defender of Usenet. :-)

killfiles (although people would probably complain at my

Subject: using emacs with perl for win32
Message-Id: <373d9ea4@news.together.net>
Hello,
I will first admit that I am a novice to perl / emacs in case you didn't
realize that from my questions.
I am using Gnu Emacs 20.3.9.1 along with perl for win32 on a win98 machine.
I'd like to use Emacs as a text editor (does anyone recommend any other good
editor that's free?) for perl. I'd like to have a split screen where I can
type at the top and then compile the script at the bottom. If there are any
errors in the script, it should report them in the bottom, otherwise it
should prompt for input (if there needs to be any) and run the script in the
bottom half. I'd also like emacs to color my text according to perl
constructs (I know it can do it for c, but what do I need to do to make it
work for perl?). I'm pretty sure this stuff can be accomplished, because
I've done it before for c and lisp programs back in college.
Thanks,
-Peter

]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.
