Hi All:
Is there a way in tk that I can use say a gif or bmp file as my
background to frame or canvas.
I would like to create a chart that has the company logo in the
backgroung, The chart ofcourse is automated where bunch of items/tags
are generated and plotted against an (X,Y) scale on-top of the gif file.
I hope I did not confuse anyone

I was speaking colloquially, using "CGI" as a shortened form of "CGI

Subject: compiling perl5.003 under BSDI 3.0
Message-Id: <33665589.41C67EA6@23.com>
I've been trying all morning to get perl5.003 compiled with gdbm
support on a box running BSDI 3.0. From reading a thousand FAQs I've
gathered that there are well known problems with BSDI's take on
dynamic linking, so I've tried to do everything statically, and gotten
myself into trouble doing that. Now I'm doing the configuration like
this:
sh configure -Dcc=gcc -Uusedl
...to tell make to ignore dynamic loading. Everything's cool until
I get to the Socket extension (which I'm assuming I need for network
applications... is this correct?), and then I get this:

Subject: Die problem
Message-Id: <5k5n0d$2ju19@hpbs1500.boi.hp.com>
I'm running Perl 5.001m. I wrote a small (very!) Perl program
to simply replace LF with LF/CR on each line of the input file,
and to save the original as <filename>.old. The original program,
listed below, works fine:
#!/usr/local/bin/perl -pi.old
s/\n/\n\r/g;
Once I had this working, I handed it off to the user that requested
the program. A few days later he came back, admitted he'd forgotten
how to use it, and asked how to use it. I explained how, and decided
to put a usage clue in there for anyone else that wanted to use it,
(or this user if he forgot again). That's when my problems started.
I added the die line as shown below, and then found out several
things:
#!/usr/local/bin/perl -pi.old
die "Usage: cradd <filename>\n" if @ARGV < 1;
s/\n/\n\r/g;
If it matters, there's a blank line between each line in the real
file.
My problem was that with the die line, the above would essentially
hang. That is, it wouldn't come back to the prompt, wouldn't run.
I found out that if I remove the -pi.old, then it would properly
prompt the user with how to use it, and quit if he didn't provide
a file name. BUT it wouldn't execute the last line if he did
provide a file name as a parameter. If I remove just the i.old,
leaving the -p, then it just hangs as when I'd first added the
die line. If I just remove the p, leaving -i.old, then again it
does nothing but does return. No changes to the file, no file with
the .old extension.
I've been to http://www.perl.com/perl and gone thru the FAQs, I've
got the O'Reilly "Programming perl" book (Purple Camel?) and have
gone thru that. I've been digging around in the man pages. I admit
it. I'm missing something somewhere in all this documentation.
What's going wrong here? What am I missing?

You're not checking whether your attempt to open the file succeeded. If
it didn't, it will produce exactly the symptom you described. Change
that to:
open(IN_FILE,"<test.txt") or die "Can't open input file: $!\n";
and check your error log after running your script. Probably your server
doesn't have permission to open the file, but why speculate?

Currently, to update my webserver's Apache password file (.passwordfile)

My problem is: how in Perl would I execute htpasswd on a username and

This is not a site, it's a newsgroup, and given that you're asking people

No, I think it still does. I installed the patch and this is one line
from the test output:
#ifndef YYDEBUG
But judging from the readme, this is a very cool patch. Thanks Jake! The
output of the version I hacked up is nearly identical to the C output,
as nearly as possible. I had ideas for making it more useful for perl5
than the raw output was, but didn't have time to implement them.
Just glancing at the code, it looks like the only real change to the
action scanning was making it handle perl comments (correct me if I'm
wrong.) I had problems with clashes between perl notation and yacc
notation. And the C-based scanning doesn't work on many common perl
constructs, for example:
s/\}//;
wouldn't work (but should on mine). @x = qw({ } }) would not work on
either system.
I also added symbol interpolation inside strings -- eg, this would work:
expr : expr '+' expr { $$ = "$1+$2"; }
And last, his is based on a 1992 version of byacc, mine on a 1996
version of bison (but no, I don't know what the differences are.)
So unfortunately, it looks like you can't have both at once now. Use
mine if you need better scanning or more recent bison features. Use
Jake's otherwise, since its output is much nicer. Or really do it right,
and take the two and integrate them. Rewrite the scanning, while you're
at it -- it's written as one big glob of C scanning code, rather than
being generated by flex (for example). Which means it's a pain to add a
new language to it, and it's brittle too.
Maybe someday I'll get around to merging the two myself. Unless Jake or
somebody else would prefer to do it... :)

I am sorry to hear that, Tom. I have read news for 12 years and this
refrain is painful to hear again. If it helps, I class your work with
posts from folks like:
Henry Spencer
Chris Torek
Doug Gwyn
Larry Wall
Dennis Ritchie
Strange - I don't see posts from many of these people anymore.
I suppose even carborundum wears down sooner or later.
Your posts have been always been very helpful, and you have done
more for the Perl community than anyone but Larry.

The same effect would be achieved by making the submission address for
the new group the same as that for comp.infosystems.www.authoring.cgi.
But as I've said before, IMO that would never get past the news.groups
crowd and would most likely be rejected by tale. I'm sure Russ Allbery
will correct me if I'm wrong.

One way to eliminate the problem would be to forbid x-posting between
clp.misc and the new groups. I can see the advantages, but wonder if this
is a bit drastic. I'm all ears if anyone has opinions they would like to
voice about this issue.

I found this refreshingly interesting. It is a java game based on a
regex class (for java), but it is very applicable to perl. And the page is
comedic to boot! (check out the garbage collection pun)

This book will be much more fun _and_ interesting, should you master this
game. :)

Subject: script producing HTML to interact with netscape
Message-Id: <01bc5546$cc179320$274d04c7@josephn.mcoe.k12.ca.us>
I have written several applications using perl to produce HTML under
Explorer.
Now I have a project that requires Netscape upload feature. The problem is:
None of my background colors showup. My background stays grey. Also no
background gifs either. Under explorer, everything functions just fine.
Any suggestions would be most appreciated. joseph.

I'd suggest starting with
perl -wc helloWorld.pl
where -w enables many useful warnings and -c checks syntax. You should
also probably look into the 'strict' and 'diagnostics' pragmas which
will further help you avoid shooting yourself in the foot. Check out
the fine documentation that comes with perl for details.

Subject: unexec'd Perl program dumps core
Message-Id: <pyenbz8i1g.fsf.1@cambridge.simoco.com>
The following message is a courtesy copy of an article
that has been posted as well.
This is a bug report for perl
from tim.wilson@cambridge.simoco.comm [remove final m],
generated with the help of perlbug 1.13 running under perl 5.003.
I have compiled perl with unexelf.c from emacs 19.34.1.
After calling dump, the resulting executables work fine most of the time,
but on the large Perl program (a compiler, about 40000 SLOC) whose
start-up time I wish to reduce,
1. firstly the program runs fine for some time
2. then Perl prints the message
Corrupt malloc ptr 0x4a9 at 0x117b800
3. then dumps core.
I do not have a small example -- my small examples all work fine :-(
Any hints, patches, or other help welcomed!
Tim

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.
