If the proposed moderation is at all effective at
weeding out obvious FAQ's and preventing mis-posted
CGI questions and long threads about scheme vs tcl,
then I wonder if there will be any added value in
splitting up the moderated version of the group
into 4 separate groups.
I, for one, would be quite happy with a single moderated
group, as I don't think the traffic would be too much to
handle (again, given effective moderation). I'm just guessing
but I figure most interested parties would likely subscribe
to all four groups anyway. At the least, if possible, it would
be nice if all posts to any of the proposed groups were automatically
cross-posted to the comp.lang.perl.programmer general group
so that one could simply subscribe to a single group and
still take part in all of the discussions on various topics.
(it would still allow those only interested in say, data-
structures, to just follow those specialized discussions).
But, I'm all for a moderated perl group (or groups) in
whatever form it (they) develop.

And what about the even simpler
@array
in a scalar context?
I have code that uses things like
if (@Newsgroups > 2) {
blahblahblah;
}
If you need to force it into a scalar context, use
scalar(@array)

Subject: bootstrapping prob w/mod_perl
Message-Id: <5kbes1$cbr@chemistry.ohio-state.edu>
I have just installed mod_perl-0.97 and CGI.pm-2.35 on Digital Unix.
modperl passes all of it's tests.
When I use CGI.pm normally, it works fine. However, when I attempt to
use mod_perl with it, it complains with:
Can't locate object method "bootstrap" via package "Apache" at
/usr/local/lib/perl5/site_perl/Apache.pm line 11.
BEGIN failed--compilation aborted at
/usr/local/lib/perl5/site_perl/CGI/Apache.pm line 2.
And, all what line 2 is doing is running the command:
use Apache ();
and line 11 from the other module runs:
bootstrap Apache $VERSION;
Any ideas for what I'm missing?
Thanks,
john

This is not a Perl question; this is a CGI question. Your question
concerns what information is provided to CGI scripts by the protocol and
what information is set by a browser under the HTTP protocol. Please ask

well, if you want an entire routine you'll need to shop somewhere else
because i'm too lazy:
perl -pi.bak -e 's/\x0D(\x0D\x0A)/$1/g;' file.txt
that works with a glob as well, although you may not want to create
hundreds of *.bak files :)

Yes. You learn how to program in Perl and modify the script such that it
will do this.
If you have a specific programming question we would be happy to help you,
but this question is hopelessly vague and essentially amounts to you
asking someone else to do your work for you. Please do not do that. Try
to make the modification yourself and then ask specific questions when you

That depends on what platform (DOS, Unix, ...?) you're using, and

You can use system() to run arbitrary Unix commands, such as a compiler
and the compiled program. Is that what you're looking for?

ICL used an Algol 68 dialect for their systems programming language, S3,
which is what the whole of their VME operating system is written in. SCL
has a vaguely similar syntax but a far simpler type system; it's still a
very nice scripting language with an efficient compiler and some useful
high-level primitives. (This is from distant memory, it's years since I
wrote any SCL, but it came as a breath of sanity after the macro-based model
of Unix shell scripts).

I am the editor of an e-mail newsletter, and am currently looking for a
cgi program that will alow people to subscribe/unsubscribe from my
webpage and then collect the address into a file that can be imported in
my e-mail program (I guess this might mean that the program will have to
insert a comma between each address).
I am currently using webcom for my web isp and they have such a program,
however, they have limited cgi capabilities so I would like to switch.
If anyone know of a program for purchase or freeware, please let me
know. The only one that I know of is from Selena Sol but it won't allow
my subscribers to unsubscribe.
Thanks a lot,

Message-Id: <33693920.67D7@cybersource.com>
I was mocked for posting to comp.lang.perl, and so, I repost here...
I'm sending mail from a perl program with the following code:
$from = 'sender@cybersource.com';
$to = 'bogus@cybersource.com';
(open(MAIL, "|/usr/bin/mail $to")) || (exit(0));
print MAIL "Errors-To: $from\n";

print MAIL "To: $to\n";
print MAIL "Subject: mail testing\n\n";
print MAIL "test with Errors-To: -> From: -> To: -> Subject:\n";
close(MAIL);
which works when $to is a valid address, but when $to can't be
delivered because it doesn't exist or such, the error mail isn't
delivered to $from, instead it goes to "jesse@cybersource.com"?!
I've tried undefing any environment variables that might identify
"jesse", but with no luck.
Anyone got any ideas on this?

It goes to the envelope sender. Important point worth shouting.
NEVER SEND MAIL FROM A PERL SCRIPT USING /usr/bin/mail!
It has tons of security problems, doesn't generally do what you want, and
causes things like this. Instead, try the following:
$from = 'sender@cybersource.com';
$to = 'bogus@cybersource.com';
open (MAIL, '|/usr/lib/sendmail -t -oi -oem') or die "fork failed: $!";
print MAIL <<"EOM";
From: $from
To: $to
Subject: mail testing
test with From, To, Subject
EOM

My assumption is that "in the Internet syntax" refers to RFC 822, which
allows (as I recall) BITNET and UUCP addresses. Son-of-1036 has already
been modified to specifically detail this and list BITNET and UUCP as
exceptions.

Of course not. I have absolutely no problem with e-mail setups which
selectively bounce messages depending on header contents. That address is
still deliverable in general.

I have no idea what internet BITNET addresses look like, but no, RFC822
does not allow UUCP addresses, unless they are in "local-part", which
can be almost anything.
The point still is, even if the address is in the right "format", that
format does not guarantee that there is a path to the recipient. For
UUCP, that means that host!user must be represented as user@host.UUCP,
but even if host is in the UUCP maps, there doesn't have to be a path to
it.

This last bit doesn't have anything to do with header contents of the
mail. It means that it will be possible and likely that some Internet
users will not be able to send mail to others because there is no
common connection. Your machine tries to connect to Joe's, but the
packets get dropped by the Big Network Company routers.

Exactly. They are two different objects with the same value.
Whether or not that is an easy concept to live with seems to depend

Depends. Often computer programs are set up to model an approximation of
the real world, with some selected attributes of the real world objects
used in the description. Depending on what you model, it might be useful
to distinguish between different objects that are identical in all selected
criteria, if only to answer the question "how many different identical
looking objects do I get with this attribute selection".

This problem was posted here about a month ago.
The htmlized docs pointed to by perlfunc.html are missing in
PerlDoc-5.004beta-html.tar.gz .
Please update. These pages are a great help to learing Perl.
Thanks, Charlie

see substr() in the perlfunc man page. you might want to scan through
the man page a couple of times to get an idea of what functions are
available. :)

Typo in your post, or is that the problem?

if you have lynx installed on your UNIX box, try:
lynx -dump <your_html_file>
or check out HTML::Parser. It's a perl module. If you would like
some assistance in your code you may want to consider posting the code
you are having problems with. You are just looking for assistance
right? You aren't actually asking if people will write all this code
for you? And not even offer any beer? That would be kind of rude.
it sure would be nice to have some beer,

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.
