Now *that's* funny.. I can see how, it *is* repetitive, but then so
is the original too.. And there isn't really much common code in the
statements to factor out, which is IMHO a key criteria for spaghetti.
It may be just that your aesthetic sense is offended by the ", last",
while mine is more offended by the elsif and the one-statement blocks.
(Shouldn't it have been ", next"? Depends on context, really..)
Of course, I guess I might've written it like:
barf "You omitted your age!" if param('age') eq "";
barf "Your age should be a number!" if param('age') =~ /\D/;
..and surrounded the whole thing in an eval {} to catch the exception
thrown in the subroutine 'barf'. Or something.

Yes. For some reason I like it. It's.. less noisy, for one thing.
And it lets me factor common statement parts out of the conditional,
something even statement modifiers can't do.

Oops. Silly me. Though it's not really obvious which behaviour is
more desirable in reality -- yours would print an empty chapter with
no title. That's probably why I missed it in the first place.
>I think the difference in our styles might be summarized: I like

I really dislike ", next" too, but I prefer it over the alternatives.
Actually, if I know the preceding expression, like push(), will always
be true, I'll frequently write "and next" instead.
A keyword like "then" as a low-precedence scalar comma would be nice.

Due to what limitation of XML::DOM? Because it has no support for xml
namespaces? If so, will this change? Is there any work on a Perl
implementation of the DOM Level 2?

I'd like to avoid the use of XQL.

*** Third North American YAPC: First Call for Participation ***
Yet Another Society
calls for your participation in
YAPC 2001
the Third North American
Yet Another Perl Conference
http://yapc.org/America/
McGill University,
Montreal, Quebec
Wednesday through Friday
June 13-15, 2001
YAPC is a place for people to meet and talk about Perl -- where
people who've done interesting things, people who are working
on the language itself, people who are using it daily,
and people who are looking to learn about it are all within
arm's reach. Some of the great authors and coders in the field
will be on hand to discuss their work, as well as the nature
and direction of Perl itself.
Please join us for three days of listening and talking about
Perl in Montreal.
** Conference registration will be available by Feb. 1, 2001 at
http://na-register.yapc.org/
Dorm rooms will be available at the University (rates TBA); the dorm
request information will be on the website and registration
form.
Registration Cost: CAD$125 (about USD$85)
** We are looking for sponsors. Please contact Kevin Lenzo
(lenzo@yapc.org) for information about how you can help
support the Yet Another society and YAPC. Much of the
necessary funding for YAPC comes from the generous donations
of our sponsors.
** Submitted papers: Submission Deadline: May 1, 2001
All topics are welcome. Here is a short list of subjects that
might be presented:
XML, CGI/Web, Interprocess Communication, GUIs (GTk, Tk),
Natural Language Processing, Interactive Perl, Agents,
Perl as Glue, Object-Oriented Perl, Scientific Applications,
Guts, Internals, JAPHs, Perl Poetry, System Administration,
DBI/DBD, Non-UNIX Perl, Security, Peer-to-Peer Communication,
Your Favourite Topic.
Please submit your abstracts to <na-author@yapc.org>. Authors
are requested to limit their abstracts to one or two paragraphs
for Lightning Talks, and to 300 words for other talks.
This year we will accept a number of types of talks:
* Lightning: 5 minutes
The lightning talks were instigated by Mark-Jason Dominus
last year in Pittsburgh, and were replicated with great
success at the European YAPC in London.
Participants speak for no more than five minutes, with the use
of conventional transparencies. Any use of data projector,
etc, is discouraged, but allowed as long as the five minute
time limit is maintained (set-up will be done as the clock
ticks). The talk ends at the five-minute mark, regardless of
whether or not the speaker has finished.
Any topic is allowed, and some have been fantastically
humourous. Lightning talks are an excellent forum for
first-time speakers.
* Standard: 20 minutes
A 'standard' talk is the preferred format. This is enough
time to start a topic, introduce it with some pithy slides,
and open up to later conversation.
* Long and Extra-Long: 45 minutes, 90 minutes
Long talks are reserved for experienced speakers covering
large topics. If you have an in-depth topic you would like
to present in some detail, perhaps with considerable
discussion, a Long or Extra-Long talk may be the format of
choice.
* Tutorial: 3 hours + break (possibly in two sets)
Half-day (or possibly full-day) tutorials.
** Please submit your abstracts to <na-author@yapc.org>! **
Thank you; we hope you will participate. If you have any questions,
please mail <na-help@yapc.org>.

Yet Another Society
vous invite à participer à
YAPC 2001
La troisième
Yet Another Perl Conference
en Amérique du Nord
http://yapc.org/America/
Université McGill,
Montréal, Québec
Du mercredi au vendredi
13 au 15 juin, 2001
YAPC est un endroit où se rencontrer et parler de Perl; où sont réunis
des gens qui ont fait des choses intéressantes, qui travaillent sur le
langage lui-même, qui utilisent ce langage tous les jours et qui
veulent en apprendre plus. Quelques uns des meilleurs auteurs et
codeurs dans le domaine seront présents pour discuter de leur travail,
ainsi que de la nature et de l'avenir du langage Perl lui-même.
Joignez-vous donc à nous à Montréal pendant trois jours pour parler et
entendre parler de Perl.
** Inscrivez-vous à la conférence dès le 1er février:
http://na-register.yapc.org/
Des résidences étudiantes pour les participants seront disponibles
sur le campus de l'université (les tarifs seront annoncés plus
tard); le formulaire d'inscription donnera toutes les informations
nécessaires à ce sujet.
Frais d'inscription à la conférence: 125$CDN (environ 85$US).
** Nous sommes à la recherche de commanditaires. Veuillez contacter
Kevin Lenzo (lenzo@yapc.org) pour savoir comment vous pouvez
encourager la Yet Another Society et YAPC. Une grande partie des
fonds nécessaires à YAPC proviennent en effet des généreuses
contributions de nos commanditaires.
** Date de tombée pour la soumission des communications: 1er mai 2001
Tous les sujets sont bienvenus. Voici une liste non-exhaustive de
sujets possibles:
XML, CGI/web, communication inter-processus, GUIs (Gtk, Tk),
traitement du langage naturel, Perl interactif, agents, Perl
comme langage-"colle", Perl orienté-objet, applications
scientifiques, entrailles, JAPHs, poésie Perl, administration de
systèmes, DBI/DBD, Perl non-Unix, sécurité, communication
'peer-to-peer', ...
Veuillez soumettre les résumés de vos communiations à
<na-author@yapc.org>. Les auteurs sont priés de limiter leurs
résumés à un ou deux paragraphes pour les communications éclair, et
à 300 mots pour les autres communications.
Cette année, nous acceptons plusieurs sortes de communications:
* Communications éclair: 5 minutes
Les communications éclair ont été introduites l'été dernier à
Pittsburgh par Mark-Jason Dominus et ont été reprises avec
beaucoup de succès au YAPC européen à Londres.
Les participants disposent d'un maximum de cinq minutes pour
présenter leur communication, habituellement à l'aide d'un
rétroprojecteur. Tout autre mécanisme de présentation est
déconseillé, mais permis dans la mesure où la limite de temps
est respectée (l'installation se fait pendant que le temps
s'écoule). La communication se termine au bout de cinq minutes,
que le présentateur ait terminé ou non.
Tout sujet est accepté, ce qui a donné lieu dans le passé à
quelques communications hautement humoristiques. Les
communications éclair constituent un excellent forum pour des
gens qui en sont à leurs premières présentations.
* Standard: 20 minutes
La communication standard constitue le format préféré. Il y a
suffisamment de temps pour introduire le sujet, présenter
quelques transparents bien choisis et permettre la discussion.
* Longue et extra-longue: 45 minutes, 90 minutes
Ces communications sont réservées aux présentateurs
expérimentés et elles couvrent des sujets plus vastes. Si vous
désirez présenter un sujet et le discuter en détail, ce format
pourrait s'avérer le plus approprié.
* Tutoriel: 3 heures + une pause
Tutoriels d'une demi-journée et possiblement d'une journée
complète.
** Veuillez soumettre vos résumés à <na-author@yapc.org> **
Nous vous remercions et nous espérons que vous participerez en grand
nombre. Si vous avez des questions, communiquez avec
<na-help@yapc.org>.

program. I want it to open the files and serch through them and rename
any links to reflect the changes. I tried a global subistitution using
a regular expression, but to no avail. Maybe I am going about it
wrong. How would you guys aproach this problem? Any advice is

Subject: Info-Zip Extraction Options
Message-Id: <24382-3A5F6142-46@storefull-244.iap.bryant.webtv.net>
I'm using `gtar -xvzf $file` to extract a tarfile on FreeBSD.
1. Is there a way to get Info-Zip to make a list of files without the
first directory name? For example, say it extracts to "Alias-1.9" with
all the extracted files inside of the Alias-1.9 folder. Can I extract
all of the files without the 'first' directory name of "Alias-1.9"?
(Note: any subsequent directories I want to keep)
2. Similarly, is there a way to get gtar to give a list of file names
without having to splice, pop, or join? I tried -t --list, etc. (I'm
trying to get a list of the extracted files to use for uploading.)
I've studied man tar and tar --help and can't figure out how to do the
above from those docs.
Thanks,
Dennis

True, scanning the group could be a lot of work for one person.
But it's better that they do a lot of work to find someone than to
make all of us do a little bit of work to chastise them and explain
why.

If I were explicitly available, I would mention it in my .sig for
all to read. I'm not explicitly available right now, but for the
right money I could entertain offers. :)

[snip]
I'm sure many people would mind unsolicited job offers. I don't
when I mention availability in my .sig, as I have before. I do
get upset when someone sends unsolicited job offers to my office
email where my boss might see it over my shoulder. :)

Amen. Filling positions here would be a blessing too.

Randal Schwartz lists himself as a consultant, as does Tad McClellan,
but I doubt we could afford their services as consultants and
I'm sure we couldn't afford to hire them full-time. Besides, if Randal
worked here he'd be bored and I'd be bored doing nothing but
administering servers. The same would probably be true of Tad or
Anno or many of the other posters here.

Almost everyone is potentially available for the right work conditions
and the right pay. Location isn't a factor for companies that have
embraced the idea of shifting bits from home. Whether or not they
would welcome a job offer at random is another story. The Perl jobs
mailing list, the job search sites, and the jobs NGs are still the
place to deal with this sort of thing, I agree. It's just that many
recruiters will give the excuse that they post here because this is
where the experts are and this is where they can better get a feel
for who has what level of expertise, so I thought I'd mention how
I would use the information found here from their point of view if
I were actually wanting to justify using this group for recruiting.
> has always seen 'location' as a big obstacle for Usenet job postings
This isn't necessarily true, although it often would be the case.
I know most companies want someone at least close enough for an
occaisional meeting at the company site even if they work from
home most of the time, and rightfully so. The Open Source projects
that have proven that collaboration over distance is feasible may
start to change some of these perceptions and requirements.
Anyway, this non-technical thread is becomeing one of the longer
ones in the newsgroup. :( I'll go ahead and end this post now,
because I don't take pride in posting one of the longest posts
in a thread of this nature, although I'm sure people have noticed
before I can be rather voluminous in my responses.

Mine too - I suspect this is a slightly dusty corner of Perl whose
implementation wasn't considered too carefully, and the context
in which the expressions were evaluated just fell out from some
natural implementation of the operator.

I'm not either, but I'm documenting it for a course, and I'd
like to have a decent explanation - for now, your piece of
code will do in the unlikely event that any asks about it.

I agree with the intuition of both of you. So why does Perl do it in
another way? Well: most likely, because that offers the most
flexibility. You can FORCE evaluation of the right hand side of the '||'
expression into scalar context. So nothing's lost here. But, if it
always would have been evaluated in scalar context, there's no way you
could have gotten the result of evaluation in list context back.
So, passing the context of the outside of the expression to the right
hand side of the offers you the most possibilities, including all of
those the "intuitive behaviour" would have offered us (Just say "scalar"
;-). So that's what Perl does. Well, I think that's why.

Still a perl novice but learning...
I'm trying to use the Net:POP3 module to interact with my POP3 mail
server. I've managed to make the connection by issuing the following
code:
my $webfile = Net::POP3->new('localhost', Port => 110, Timeout => 60)
or die "Cannot open mail server $!";
Now, I'd like to retrieve the number of messages so I tried the
following:
my $nummsgs = $webfile.login('my_user', 'my_password')
or die "Error retrieving number of messages $!";
I get the error: Undefined subroutine &main::login called at lclmail.pl
line 11.
What I really need is some documentation on how to use the module as the
author has provided no examples of how to use the methods besides the
constructor.

Try $webfile->login('my_user', 'my_password')

That is because those instructions would not be specific to that module.
Your confusion is in how to call methods off of an object. You may find
the results of the following code surprising...
my $a = "hello, world!";
print $a.localtime(time);
The perltoot and perlobj manpages talk about objects in Perl, but are
pretty detailed and seem to be intended for object programmers.

Wow, that's odd... I really remember having read this somewhere. Too
[much|less] coffee. :)
And by the way, I'm still out of it when I say:
chdir(<FROM>); # evil!
This is not working. In fact, it brings me back to my home dir.
Oh well..

What is the syntax internal to the suffixlist? Must the values
there be separated by commas? Must it be a scalar? Perhaps
maybe it could be a scalar with mulitple values, separated by
spaces?
I'm not familiar with the tools you are using, but these could
be issues leading to your crash if they are important to the
package.

Please say the book gives a description of what should be in
suffixlist. It could be that it needs to be a "list" of values,
but not given in Perl's list context (for example, a scalar, a
comma-separated list of multiple scalars, or a scalar containing
comma-separated values).
See if any of these work for basename:
$work = basename($file, '.xml', '.csv', '.ini');
my @suff = ('.xml', '.csv', '.ini');
$work = basename($file, join(',', @suff) );
my $suffixes = ('.xml', '.csv', '.ini');
$work = basename($file, $suffixes);

I have very rarely found a case in which Perl had a problem with
memory alignment causing a crash or saving me from one. As a matter
of fact, I'm not sure I've ever found a problem caused by this that
didn't already have severe errors in my code. When I say severe, I
mean really hideous things that only get done in the dawning hours
after all the coffee is gone. Perl, being handled by a system
somewhere between pure interpretation and pure compilation but not
quite "jit", protects you from a lot of the intricacies of memory
problems. A high-level language should. (If you consider C high-level,
then you should realize that I make the previous statement considering
C to be mid-level. I don't think anythign breaks cleanly into two
parts, especially high-level vs. low-level languages.)
I'm not sure what you are doing is a workaround. It may be simply
more correct for the tools you are using. It may be a working
workaround that is no more technically correct. It may not even
be a complete workaround, as under stress or in production many
"workarounds" fail to work around things. My bet is, though, that
you've found one of possibly many ways to not just alleviate your
problem, but to eradicate it. There may be other ways which work
as well, but maybe not. I wish I knew more about your particular
dilemma so I could offer advice that is more helpful.

Yes, I'd expect most system admins have written things like this.

Image::Magick should be able to do this.
