1. Go to a command prompt. Type 'perl -v<return>'. You should get a
version report.
2. Write a file containing:
#perl -w
use strict;
print "Hello, world!\n";
>From the command line, type 'perl your_file<return>'. It should speak
back to you.
3. From the Start menu, go to the ActivePerl group, click on 'Online
Documentation', and 'have the appropriate amount of fun!'

A disturbingly astute observation, Greg. Maybe we all should take the
lesson that the signal-to-noise ratio of the newsgroup would be improved
three-to-one if flamers simply ... didn't.

Subject: bareface ratio
Message-Id: <37543D13.109FD1C8@xli.com>
just an interesting phenomenon I've noticed
on newsgroups in general.
bareface ratio:
the number of people who respond
to tell you your information is wrong
versus
the number of people who respond
to your requests for information
on the same topic.
this seems to be about 3 (or more) to 1,
depending on the topic.
so, if you have a question, and no one
is responding, you can still get the
answer, all you have to do is make something
up first (bareface it), and the
corrections will flood in.

From: Greg Bartels <gbartels@xli.com>
Subject: definition of public domain
Message-Id: <37543974.B1DC9BB5@xli.com>
the following definition is taken from
O'Reilly's book, "Open Sources"
(asterisks added by me.)
Public Domain
A common misconception is that much free software
is public-domain. This happens simply because the
idea of free software or Open Source is confusing
to many people, and they mistakenly describe these
programs as public-domain because that's the closest
concept that they understand. The programs, however,
are clearly copyrighted and covered by a license,
just a license that gives people more rights
than they are used to.
A public-domain program is one upon which the author
has deliberately surrendered his copyright rights.
It can't really be said to come with a license; it's
your personal property to use as you see fit.
Because you can treat it as your personal property,
you can do what you want with a public-domain program.
You can even re-license a public-domain program,
removing that version from the public domain, or
you can remove the author's name and treat it as
your own work.
If you are doing a lot of work on a public-domain
program, consider applying your own copyright to
the program and re-licensing it. For example, if
you don't want a third party to make their own
modifications that they then keep private, apply
the GPL or a similar license to your version of
the program. ***The version that you started with will
still be in the public domain, but your version will
be under a license that others must heed if they use
it or derive from it.***
You can easily take a public-domain program private,
by declaring a copyright and applying your own license
to it or simply declaring "All Rights Reserved."

but s2 is expecting an array ref so it fails here. passing @foo works
since the prototype can convert a named array to an array ref at compile
time. (1,2,3) is a list and is passed as a list of values. where can
perl deduce that it should be a single array ref or multiple array refs?
what if the values were:
([1], [2], [3])
should that be converted to
[ [1], [2], [3] ]
or passed as 3 array refs like it is now?
so you must get the difference between a named array argument and a
plain list. they are not the same with prototypes as the are not the
same with push, pop, @foo in scalar context, etc. named arrays are
compile time objects, lists are not.

again, how can you tell what the caller means when passing those two

No, you can't. The method proposed is deceptive, and not just due to
real machines. You're forgetting proxies (sometimes second-level caches
and chaining, too) and browser-level caching. Better to plead guaranteed
ignorance than to believe a facile lie.
Consider this not uncommon situation: I have more something handful and
a half of random machines scattered across four different subnets, a
couple dozen or so random users, an aggressively caching proxy with a big
filesystem to fill up, and per-client caches as well. The Mac tends be
communal. I refuse to provide cookies, referrer, or browser information.
So these all look the same by the most common method, thus proving how
truly inaccurate this is, and why it's an idiotic vanity device to waste
your life on "hit counters".
Professionals don't need hit counters.

Yes, and initial ignorance is specific to neither Unix nor Perl
as well. My point was lost somewhere in there, I'm afraid.

I am new to Perl, and I'm working on a program to parse fairly simple HTML
files and convert their content to plain text files for use by another system.
I posted an earlier question regarding the use of the .* characters in a
substitution command. While reading more info, however, I saw several
references to a package called HTML::Parser.
What is this? Is it freeware/shareware? How do I get and use it? Is there a
URL where I can find out more about this? It sounds like something that has

Message-Id: <Pine.SOL.3.96.990601153426.8576A-100000@ux13.cso.uiuc.edu>
I'm working on a script to create a html page from a (.csv) file and
update several index pages. Right now, i have the pages looking the way i
want them to, but i can't come up with a good algorithm to keep the
indexed resources alphabetized while adding a new link to it.
Basically i'm wondering if something already exists in perl (a function)
that alphabetizes.. if not, what is my approach? comparing strings from
each line and formatting accordingly.. (sounds rather complicated, i think
there's something out there) so i'm looking around..
thanks for any help,
m-andric@uiuc.edu

How hard are you looking? Perl would be a pathetic general-purpose
programming language if it didn't have a facility that alphabetized,
wouldn't it?
perldoc -f sort

If you're storing your data in an array or hash, then all you
need to do is to look up the function sort() in your perlfunc
section (via man, perldoc, a browser if you have the HTML also,
...) You might also want to look in the FAQ for the question:
"How do I sort an array by (anything)?" as well as the URL:
http://www.perl.com/CPAN/doc/FMTEYEWTK/sort.html .
If you're not storing your data as above, then you need to give
us more information, so we can give you some adequate advice.
Perhaps a 10 or 20 line program that encapsulates your issues.
HTH,
David

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.
]From: Russ Allbery <rra@stanford.edu>

]Subject: comp.lang.perl.moderated available via e-mail
]
]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.
