Subject: /bin/sh -x output for perl?
Message-Id: <6t878h$9s6$1@nnrp1.dejanews.com>
Hiya,
I'm a perl newbie. I have just came across some perl code and I need to
understand how it works without actually running the code.
I know in the Bourne shell, there is this command -x. This command will
actually run the script but not execute the commands. So, I can see the output
and trace through the code to understand what each part is doing.
Is there a similar switch in perl that I can use?
I have tried the -w switch as recommened in the FAQ but it just checks the
syntax and does not give the running output.
TIA
yee koon

education purposes based around an 8051 microcontroller using the Keil C
Compiler. In addition. I have taken part in group IC design and embedded
system design projects.
Details of my final year project can be found at:

The first parameter to 'split' is a regular expression. Read up on regular
expressions ('perldoc perlre' is a good start) until you can work one out that
matches various numbers of spaces.

Subject: Need help from users of Mail::*
Message-Id: <Ez27tF.1sn@oce.nl>
I want to create a gizmo that allows one to post replies to archived mail
articles grabbed from HTML archives. The idea is that the user starts from
the URL of an HTML file generated by 'hypermail'; out of it I get the
archived article in HTML form, something like:

<!-- nextthread="start" -->
</ul>
and post the requesting user a mail message to which (s)he does a "reply to
all" to post a follow-up to the original thread.
In need someone's experience with Mail::* to give me some hints (OK, I can
RTFM, but I want a kickstart; call me lazy if you wish -- anyway I'm not a
RFC822/sendmail/SMTP expert) towards the required Perl code to send the mail
with the proper headers (massaging the message _body_ should be a
nobrainer).
I'm somewhat lucky: hypermail preserves the original header fields in the
form of HTML comments!
TIA for any help.

I have had success with the Storable module, doing exactly what you
want. Unfortunatly i do not have access to RPC on the remote site, so
i have written a modules that does RPC through a httpdaemon passing
objects back and forth.
My next step is to implement encryption and authentication on the
protocol (using multiple types, so you can have SSL or some other
algorithm at will).
I will be looking into making a Java class for serializing /
deserializing data encoded by Storable, so I can exchange objects
between Java & Perl (Corba doesn't exchange objects, just
references!).

No it doesn't.
It comes from the verb "to hack", as it "to cut with rough blows" or
"to chop or mangle". Ie. to set about something in a rough-and-ready
fashion.

Is the page with the script the only page in the secure area? i mean, if
not, a user could bookmark a different page than the one you want him to go
to and never have his access count decreased. maybe you could set a session
cookie and include an ssi execcgi in every page. store the cookie value in
the DB with session count and decrement when the cookie changes.

I placed the less than 1k gif files in the cgi directory as well as
the default directory of the web site. The program is called from
various subdirectories of the site. I think the problem also has to
do with my placing the images within one of the separate form tables
generated, not directly on the background page. Will try putting the
images on the background page generated too. Not as effective but,
perhaps the easy way to do this.

Subject: problem with recursion in perl
Message-Id: <6t8apa$a2r$1@plug.news.pipex.net>
I'm pretty new to perl (in fact this is the first script I've written - and
I already have problems!!). The script below is a cut down version of the
one I've written, it's designed to recursively go through a directory
structure and print out whether it's a directory or a file (the real version
creates html based on this information to create a directory structure that
can be navigated on the browser).
It starts out OK but on the way out of the recursion it seems to lose the
ability to tell if a file is a directory or file.
I've tried it on NT and unix.
Is this a known problem? Am I trying to do things I shouldn't? and does
anyone have a way around it?
Any help would be very much appreciated.
The script:
print "Content-type: text/html\n\n";
&printdir("/home/gevans");
sub printdir {
if (chdir $_[0]){
foreach (<*>){
if (-d $_){
print "$_ is a directory\n";
&printdir($_[0] . "/" . $_);
}else{
print "$_ is a file\n";
}
}
}else{
print "error changing directory";
}
return;
}

use Sybase::DBlib;
This falls over with:
Can't locate Sybase/DBlib.pm in @INC (@INC contains: /usr/local/lib/perl5
/usr/local/lib/perl5 /usr/local/lib/perl5 .) at ...
I have created a softlink to some of the sybperl pm modules etc in
/usr/local/lib/perl5 where my perl modules are but this is not mentioned in
the sybperl installation guide and really doesn't seem right to me. Should I
be doing this?
My questions are thus:
1. Do I have to recompile the perl binary after installing sybperl?
2. What environment variables must be set for sybperl?
3. Does the sybperl installation try to link itself to perl when installing
sybperl?
4. What exactly is happening with the sybperl installation?
thanx
Malcolm

Subject: uniq
Message-Id: <6t7rqe$b9v$1@news.tdl.com>
is there a (good) way to do uniq entirely within perl (no exec of the
utillity)?
I really even need the uniq'd list, just a count of the uniq lines in a list.
(this is then uniq -n [print all lines once only], or in some versions that
do not have -n, uniq -du)
E-mail replies preferred.
Thanks!

there are several methods for getting the unique elements of an
array (list) in perlfaq4:
perlfaq4.pod:=head2 How can I extract just the unique elements of an array?
perhaps one of them might be of some help in your situation.

Subject: What version does the CPAN doc document?
Message-Id: <6t7vbi$hl2@janus.ocegr.fr>
In my recent woes with Perl patterns I tried to use '\z' (yes, lowercase)
because the perlre.html I found on CPAN mentioned it. As several people
mentioned, it doesn't exist; and I indeed can't find it when I do 'man
perlre' on my Solaris 2 5.004_1 setup.
Is this a 5.005 feature? If yes, where is this kind of addition documented
(in a detailed "whatsnew for 5.005" kind of doc, maybe?) If not, what does
this perlre.html refer to?
TIA

If you're on NT, get 4NT. For Win9x stick with 4DOS. They're at

Or if you want a nice Unixy environment, get the cygwin32 package. It
includes the bash shell, most of the commonly used Unix utilities, and
gcc. http://www.cygnus.com/misc/gnu-win32

Subject: Special: Digest Administrivia (Last modified: 12 Mar 98)
Message-Id: <null>
Administrivia:
Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
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.
