Posting Guidelines for comp.lang.perl.misc ($Revision: 1.8 $)
This newsgroup, commonly called clpmisc, is a technical newsgroup
intended to be used for discussion of Perl related issues (except job
postings), whether it be comments or questions.
As you would expect, clpmisc discussions are usually very technical in
nature and there are conventions for conduct in technical newsgroups
going somewhat beyond those in non-technical newsgroups.
The article at:
http://www.catb.org/~esr/faqs/smart-questions.html
describes how to get answers from technical people in general.
This article describes things that you should, and should not, do to
increase your chances of getting an answer to your Perl question. It is
available in POD, HTML and plain text formats at:
http://www.rehabitation.com/clpmisc.shtml
For more information about netiquette in general, see the "Netiquette
Guidelines" at:
http://andrew2.andrew.cmu.edu/rfc/rfc1855.html
A note to newsgroup "regulars":
Do not use these guidelines as a "license to flame" or other
meanness. It is possible that a poster is unaware of things
discussed here. Give them the benefit of the doubt, and just
help them learn how to post, rather than assume that they do
know and are being the "bad kind" of Lazy.
A note about technical terms used here:
In this document, we use words like "must" and "should" as
they're used in technical conversation (such as you will
encounter in this newsgroup). When we say that you *must* do
something, we mean that if you don't do that something, then
it's unlikely that you will benefit much from this group.
We're not bossing you around; we're making the point without
lots of words.
Do *NOT* send email to the maintainer of these guidelines. It will be
discarded unread. The guidelines belong to the newsgroup so all
discussion should appear in the newsgroup. I am just the secretary that
writes down the consensus of the group.
Before posting to comp.lang.perl.misc
Must
This section describes things that you *must* do before posting to
clpmisc, in order to maximize your chances of getting meaningful replies
to your inquiry and to avoid getting flamed for being lazy and trying to
have others do your work.
The perl distribution includes documentation that is copied to your hard
drive when you install perl. Also installed is a program for looking
things up in that (and other) documentation named 'perldoc'.
You should either find out where the docs got installed on your system,
or use perldoc to find them for you. Type "perldoc perldoc" to learn how
to use perldoc itself. Type "perldoc perl" to start reading Perl's
standard documentation.
Check the Perl Frequently Asked Questions (FAQ)
Checking the FAQ before posting is required in Big 8 newsgroups in
general, there is nothing clpmisc-specific about this requirement.
You are expected to do this in nearly all newsgroups.
You can use the "-q" switch with perldoc to do a word search of the
questions in the Perl FAQs.
Check the other standard Perl docs (*.pod)
The perl distribution comes with much more documentation than is
available for most other newsgroups, so in clpmisc you should also
see if you can find an answer in the other (non-FAQ) standard docs
before posting.
It is *not* required, or even expected, that you actually *read* all of
Perl's standard docs, only that you spend a few minutes searching them
before posting.
Try doing a word-search in the standard docs for some words/phrases
taken from your problem statement or from your very carefully worded
"Subject:" header.
Really Really Should
This section describes things that you *really should* do before posting
to clpmisc.
Lurk for a while before posting
This is very important and expected in all newsgroups. Lurking means
to monitor a newsgroup for a period to become familiar with local
customs. Each newsgroup has specific customs and rituals. Knowing
these before you participate will help avoid embarrassing social
situations. Consider yourself to be a foreigner at first!
Search a Usenet archive
There are tens of thousands of Perl programmers. It is very likely
that your question has already been asked (and answered). See if you
can find where it has already been answered.
One such searchable archive is:
http://groups.google.com/advanced_group_search
If You Like
This section describes things that you *can* do before posting to
clpmisc.
Check Other Resources
You may want to check in books or on web sites to see if you can
find the answer to your question.
But you need to consider the source of such information: there are a
lot of very poor Perl books and web sites, and several good ones
too, of course.
Posting to comp.lang.perl.misc
There can be 200 messages in clpmisc in a single day. Nobody is going to
read every article. They must decide somehow which articles they are
going to read, and which they will skip.
Your post is in competition with 199 other posts. You need to "win"
before a person who can help you will even read your question.
These sections describe how you can help keep your article from being
one of the "skipped" ones.
Is there a better place to ask your question?
Question should be about Perl, not about the application area
It can be difficult to separate out where your problem really is,
but you should make a conscious effort to post to the most
applicable newsgroup. That is, after all, where you are the most
likely to find the people who know how to answer your question.
Being able to "partition" a problem is an essential skill for
effectively troubleshooting programming problems. If you don't get
that right, you end up looking for answers in the wrong places.
It should be understood that you may not know that the root of your
problem is not Perl-related (the two most frequent ones are CGI and
Operating System related), so off-topic postings will happen from
time to time. Be gracious when someone helps you find a better place
to ask your question by pointing you to a more applicable newsgroup.
How to participate (post) in the clpmisc community
Carefully choose the contents of your Subject header
You have 40 precious characters of Subject to win out and be one of
the posts that gets read. Don't waste them. Take care while
composing them, they are the key that opens the door to getting an
answer.
Spend them indicating what aspect of Perl others will find if they
should decide to read your article.
Do not spend them indicating "experience level" (guru, newbie...).
Do not spend them pleading (please read, urgent, help!...).
Do not spend them on non-Subjects (Perl question, one-word
Subject...)
For more information on choosing a Subject see "Choosing Good
Subject Lines":
http://www.cpan.org/authors/id/D/DM/DMR/subjects.post
Part of the beauty of newsgroup dynamics, is that you can contribute
to the community with your very first post! If your choice of
Subject leads a fellow Perler to find the thread you are starting,
then even asking a question helps us all.
Use an effective followup style
When composing a followup, quote only enough text to establish the
context for the comments that you will add. Always indicate who
wrote the quoted material. Never quote an entire article. Never
quote a .signature (unless that is what you are commenting on).
Intersperse your comments *following* each section of quoted text to
which they relate. Unappreciated followup styles are referred to as
"top-posting", "Jeopardy" (because the answer comes before the
question), or "TOFU" (Text Over, Fullquote Under).
Reversing the chronology of the dialog makes it much harder to
understand (some folks won't even read it if written in that style).
For more information on quoting style, see:
http://web.presby.edu/~nnqadmin/nnq/nquote.html
Speak Perl rather than English, when possible
Perl is much more precise than natural language. Saying it in Perl
instead will avoid misunderstanding your question or problem.
Do not say: I have variable with "foo\tbar" in it.
Instead say: I have $var = "foo\tbar", or I have $var = 'foo\tbar',
or I have $var = <DATA> (and show the data line).
Ask perl to help you
You can ask perl itself to help you find common programming mistakes
by doing two things: enable warnings (perldoc warnings) and enable
"strict"ures (perldoc strict).
You should not bother the hundreds/thousands of readers of the
newsgroup without first seeing if a machine can help you find your
problem. It is demeaning to be asked to do the work of a machine. It
will annoy the readers of your article.
You can look up any of the messages that perl might issue to find
out what the message means and how to resolve the potential mistake
(perldoc perldiag). If you would like perl to look them up for you,
you can put "use diagnostics;" near the top of your program.
Do not re-type Perl code
Use copy/paste or your editor's "import" function rather than
attempting to type in your code. If you make a typo you will get
followups about your typos instead of about the question you are
trying to get answered.
Provide enough information
If you do the things in this item, you will have an Extremely Good
chance of getting people to try and help you with your problem!
These features are a really big bonus toward your question winning
out over all of the other posts that you are competing with.
First make a short (less than 20-30 lines) and *complete* program
that illustrates the problem you are having. People should be able
to run your program by copy/pasting the code from your article. (You
will find that doing this step very often reveals your problem
directly. Leading to an answer much more quickly and reliably than
posting to Usenet.)
Describe *precisely* the input to your program. Also provide example
input data for your program. If you need to show file input, use the
__DATA__ token (perldata.pod) to provide the file contents inside of
your Perl program.
Show the output (including the verbatim text of any messages) of
your program.
Describe how you want the output to be different from what you are
getting.
If you have no idea at all of how to code up your situation, be sure
to at least describe the 2 things that you *do* know: input and
desired output.
Do not provide too much information
Do not just post your entire program for debugging. Most especially
do not post someone *else's* entire program.
Do not post binaries, HTML, or MIME
clpmisc is a text only newsgroup. If you have images or binaries
that explain your question, put them in a publically accessible
place (like a Web server) and provide a pointer to that location. If
you include code, cut and paste it directly in the message body.
Don't attach anything to the message. Don't post vcards or HTML.
Many people (and even some Usenet servers) will automatically filter
out such messages. Many people will not be able to easily read your
post. Plain text is something everyone can read.
Social faux pas to avoid
The first two below are symptoms of lots of FAQ asking here in clpmisc.
It happens so often that folks will assume that it is happening yet
again. If you have looked but not found, or found but didn't understand
the docs, say so in your article.
Asking a Frequently Asked Question
It should be understood that you may have missed the applicable FAQ
when you checked, which is not a big deal. But if the Frequently
Asked Question is worded similar to your question, folks will assume
that you did not look at all. Don't become indignant at pointers to
the FAQ, particularly if it solves your problem.
Asking a question easily answered by a cursory doc search
If folks think you have not even tried the obvious step of reading
the docs applicable to your problem, they are likely to become
annoyed.
If you are flamed for not checking when you *did* check, then just
shrug it off (and take the answer that you got).
Asking for emailed answers
Emailed answers benefit one person. Posted answers benefit the
entire community. If folks can take the time to answer your
question, then you can take the time to go get the answer in the
same place where you asked the question.
It is OK to ask for a *copy* of the answer to be emailed, but many
will ignore such requests anyway. If you munge your address, you
should never expect (or ask) to get email in response to a Usenet
post.
Ask the question here, get the answer here (maybe).
Beware of saying "doesn't work"
This is a "red flag" phrase. If you find yourself writing that,
pause and see if you can't describe what is not working without
saying "doesn't work". That is, describe how it is not what you
want.
Sending a "stealth" Cc copy
A "stealth Cc" is when you both email and post a reply without
indicating *in the body* that you are doing so.
Be extra cautious when you get upset
Count to ten before composing a followup when you are upset
This is recommended in all Usenet newsgroups. Here in clpmisc, most
flaming sub-threads are not about any feature of Perl at all! They
are most often for what was seen as a breach of netiquette. If you
have lurked for a bit, then you will know what is expected and won't
make such posts in the first place.
But if you get upset, wait a while before writing your followup. I
recommend waiting at least 30 minutes.
Count to ten after composing and before posting when you are upset
After you have written your followup, wait *another* 30 minutes
before committing yourself by posting it. You cannot take it back
once it has been said.

Have you ever tried highlighting a message (in OE) and then going to
File and Save As? This will save the raw article, headers & all (what is
sometimes referred to as "mbox format".)
Also, you can right click a highlighted message and use "Copy to Folder"
to save a copy in your local OE folders.

That they are local OE folders is precisely my bitch about it.

The "Save As..." function saves the text in locations outside any OE folders.
So what's the problem?

: I want to remove an element from an array whose index i dont know.
Let's first look at your code from a bottom-up perspective:
: #!/usr/bin/perl -w
: use strict;
This is a good habit. These days, people tend to drop the -w
switch and use the warnings pragma instead, as in
#! /usr/bin/perl
use warnings;
use strict;
: my @updateNames = ();
:
: push @updateNames,"I_love_you";
: push @updateNames,"I_love_you_too";
: push @updateNames,"I_hate_you";
Arrays start out empty, so the assignments aren't strictly necessary.
There are cases where you might want to be explicit for purposes of
emphasis.
In your case, you explicitly set @updateNames to the empty list and
then push values onto it. You can initialize arrays when you declare
them, as in
my @updateNames = (
"I_love_you",
"I_love_you_too",
"I_hate_you",
);
: foreach $item (@updateNames)
: {
: foreach $item2 (@tempArr)
: {
: if ($item eq $item2)
: {
: pop @updateNames,$item;
: }
: }
: }
Someone else already noted (but it doesn't hurt to repeat!) that
you shouldn't modify a collection while you're iterating over it.
The pop operator doesn't work the way you seem to think it does.
(With warnings enabled, you should have seen "Useless use of private
variable in void context" about that line.)
With pop, you supply an array as its only operand, and the result
is that the array's last element (if any) disappears.
: print "\n";
: foreach $item (@updateNames)
: {
: print $item;
: print "\n";
: }
Now from the top-down: at a high level, what are you trying to do?
Do you want to print all elements in @updateNames that are not in
@tempArr? If so, you can simplify your code:
#! /usr/bin/perl
use warnings;
use strict;
my @updateNames = (
"I_love_you",
"I_love_you_too",
"I_hate_you",
);
my %exclude;
$exclude{$_}++ for (
"I_love_you",
"I_love_Him",
"I_hate_you",
);
foreach my $item (@updateNames)
{
print $item, "\n" unless $exclude{$item};
}
As a helpful hint, prefer to search hashes over arrays.
I hope this helps,
Greg

Subject: searching for a special string in an array
Message-Id: <1184051896.038236.158180@57g2000hsv.googlegroups.com>
Hi,
I'm running on an array of strings with a foreach loop.
I want to stop the loop when I find the string: "item(s)" - but it
looks like I have problems with defining the if condition.
I tried:
if ($str=~"item(s)") {
last;
}
But it seems to have problems. if I remove the "(s)" it works fine but
I need to find a unique string which contains exactly this: "item(s)".
Any idea ?!?!?
Thanks,
Shai.

The parentheses are special, they are used to capture part of the match:
my $str =3D 'items';
if ($str =3D~ "item(s)") {
print "match: \$1=3D$1\n";
}
BTW Better stick with the usual "/" characters to delimit patterns:
my $str =3D 'item(s)';
if ($str =3D~ /item\(s\)/) {
print "Match!!\n";
}

Don't specify a regular expression as a string. While Perl does what
you mean and interprets it as a regex, it's confusing and less robust
than it could be.

If you're only looking for a substring you can use index():
if ( index( $str, 'item(s)') >= 0 ) { # ...
In a regex, the parens have special meaning and must be escaped:
if ( $str =~ /items\(s\)/ ) { # ...

First, you should make yourself clear the difference between
authentitication and authorization:
* authentication is establishing who a user is.
* authorization is establishing what a user is allowed to do.
HTTP Basic authentication muddies the distinction both in the headers
(The server sends a WWW-Authenticate header and the client responds with
an Authorization header) and in the behaviour of the common browsers.
But it is still very useful to keep them apart.
In HTTP basic authentication, a user is identified by four pieces of
information:
1) The server (identified by protocol, server and port).
2) The Realm (as sent in the WWW-Authenticate header and specified in
the AuthName directive in Apache)
3) The user name (as sent by the client in the Authorization header).
These three pieces uniquely identify a user. If one of them is
different, it is a different user. For the user to prove that he really
this user (to "authenticate" itself), the fourth piece is needed:
4) The password (sent by the client in the Authorization header).
Once you have authenticated the user, you need to decide what he can do.
For example Alice may access directory directory A, but not Directory B,
while Bob may access both directories.
In the Apache config, this is done with allow/deny and require
directives.
Note that HTTP has no way to confer that a user has successfully
authenticated, but is not authorized to access some resource. Both a
failed authentication and an attempt to access a resource without proper
authorization result in a 401 code. So when the browser receives a 401
code, it doesn't know whether the user supplied a wrong username or
password or isn't allowed to access that resource. So it pops up a
dialog box asking for username and password in either case.

So you want to create a page containing only links which the user is
authorized to visit? Once a user has been authenticated, you can easily
do that if you know where the user has access (that sounds trivial, but
may not be - you may need to parse server config files and .htaccess
files to find out).

No. CGI::Auth is concerned with Authentication, not Authorization.
At first glance, CGI::Auth may help you in two aspects:
1) It doesn't use Basic Authentication, so you can distinguish between
lack of authentication and authorization - you can tell a user "you
aren't allowed to go there" without his browser losing the login
information.
2) Since you are doing authentication yourselves, you also need to edo
authorization - so if you want dynamic menus, you don't need to
parser your server config files to find out where the user is allowed
access.
But at second glance it is obvious that you don't need CGI::Auth for
this. You get the same effect if you use Apache only for authentication,
and do the authorization in your scripts.
