[ That "Last-modified:" date above refers to this document, not to the
Perl FAQ itself! The last major update of the Perl FAQ was in Spring of
1997; of course, ongoing updates are made as needed. ]
For most people, this URL should be all you need in order to find Perl's
Frequently Asked Questions (and answers).
http://cpan.perl.org/doc/FAQs/
Please look over (but never overlook!) the FAQ and related docs before
posting anything to the comp.lang.perl.* family of newsgroups.
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
Beginning with Perl version 5.004, the Perl distribution itself includes
the Perl FAQ. If everything is pro-Perl-y installed on your system, the
FAQ will be stored alongside the rest of Perl's documentation, and one
of these commands (or your local equivalents) should let you read the FAQ.
perldoc perlfaq
man perlfaq
If a recent version of Perl is not properly installed on your system,
you should ask your system administrator or local expert to help. If you
find that a recent Perl distribution is lacking the FAQ or other important
documentation, be sure to complain to that distribution's author.
If you have a web connection, the first and foremost source for all things
Perl, including the FAQ, is the Comprehensive Perl Archive Network (CPAN).
CPAN also includes the Perl source code, pre-compiled binaries for many
platforms, and a large collection of freely usable modules, among its
560_986_526 bytes (give or take a little) of super-cool (give or take
a little) Perl resources.

http://www.perl.com/CPAN/
http://cpan.perl.org/doc/FAQs/FAQ/html/perlfaq.html
http://www.perl.com/CPAN/doc/FAQs/FAQ/html/perlfaq.html
You may wish or need to access CPAN via anonymous FTP. (Within CPAN,
you will find the FAQ in the /doc/FAQs/FAQ directory. If none of these
selected FTP sites is especially good for you, a full list of CPAN sites
is in the SITES file within CPAN.)

If you have no connection to the Internet at all (so sad!) you may wish
to purchase one of the commercial Perl distributions on CD-Rom or other
media. Your local bookstore should be able to help you to find one.
Another possibility is to use one of the FTP-via-email services; for

Hi,
The most serious error seems to be that you don't increment your
loop variable $i.
Replace
for (...; ...; $i)
with
for (..., ..., $i+-+-)
Learning to use the perl debugger will make these error jump
out at you, instead of having to post to the newsgroup for a
much slower response. HTH.

Subject: Chomp() on win32 and unix perl
Message-Id: <6of8p1$cu2$1@flex.london.pipex.net>
Hi all,
I've just come across an interesting problem which I personally think
shouldn't
exist.
The problem : On Win32 perl (5.004_69) a "chomp" recogises both the
windows nt and unix line endings (\r\n for NT and \n for unix), so all is ok
when converting scripts.
But, when reading in an NT file on UNIX (5.004_01), a "chomp" only strips
off the "\n" and leaves
the "\r" in the file, thus creating problems when diffing etc.
Surely the chomp command on unix perl should recognise the NT line endings
in
the same way the Win32 Perl recognises both. ??
Just a thought.

Ugh. Why would anyone want that? I would be extremely unhappy if Perl chomped
off more than I asked it to . . .
On Unix, the line terminator is a single character. chomp() removes the line
terminator. It is simply fortuitous for you that it still treats a single
newline as a line terminator in the Win32 world. Any embedded carriage returns
in files created on *nix systems are probably intentional, and it would
certainly cause problems to whack 'em off should they be located adjacent to
newlines.

chomp() is documented to remove $/ from the end of a string. Here's
a hint:
#!//c/perl/bin/perl -w
$/ = "!\n";
chomp(my @foo = <DATA>);
print map "<$_>\n", @foo;
__DATA__
mr magoo!
donald trump!
arthur pfeffer!
Also: use ASCII mode when transferring your file between platforms;
this will automagically translate end-of-line sequences between
platforms.
Finally, you may configure your text editor on the NT box to save as
Unix. HTH.

Who said I was using FTP ? As it happens these files are stored on a unix

Fine if it was just me, but we're talking about a big development team
comparing the results
of NT and UNIX test results.
(btw, I use PFE on NT, so its not a problem, the problem is the developers

As I have just started with perl I though I would give you a hand. The
first question is do you have any experience with programming? If you do
perl should be quite pleasant and easy to get the hang of, especially
for what you want to do. If you have no programming experience you will
probably have a harder time. The best thing to do in both situations is
get a nice Perl book that will explain the basiscs, you will find that
the information on the web probably won't do the trick! Perl is very
much suitable for your objective.
Greets,
Nico.

The main suggestion is to try something that works: using a command
prompt window. Running command line programs from Explorer is bad for
the reason you've already noticed: a console window flashes on the
screen and you have no idea what is going on. If you open up a
permanent command prompt first, it won't close and you can see what's
going on. Perl is so command line oriented that it's tough to use it
from a GUI.
If you have a lot of output, so much that it is more than a single
command prompt screen, you'll likely want to use a text editor that
captures output. M-x shell in Win32 Emacs is the best one I've seen.
The free Programmer's File Editor also has a way to run commands and
capture the output into a buffer. You'll almost certainly want
an editor that lets you have multiple buffers open at once, like
Emacs, so you can edit and run in the same editor.

Alternatively, I believe that on Win95 you can do the following: I can't
guarantee, but I remember doing something similar for Fortran. I'll
check this evening:
Make a .bat file in which you write something like that:
@echo off
c:\perl\perl.exe %1
Associate Perl with that Batfile. Its gotta look something like this :
'c:\mybats\perl.bat %1'
Now Right click on the batfile, and I think that you should get all
sorts of properties thrown at you. If I remember correctly you can
choose some kind of 'Don't close window after finishing'.
Hope that helps.

Suppose you have the ouput already on the page -- [untested]
$i = 0;
while (<FILE>) {
print "$_",checkbox(-name=>"$i"),"<br>";
$i++;
}
I would do something like that, J *giggle*: -- [untested]
@file = <FILE>;
for ($count = @file; $count >= 0; $count--) {
splice (@file, $count, 1) if param("$count");
}
write array back to file;
Alternatively I have used textareas in my link manager - Print the
contents of the file into the textarea with the -default => hash key,
and then just write the contents of the textarea back.

Do you really want that ? Rumours say that you can't be a skillful

Subject: Perl embedding question - embedding code which calls dyn. modules?
Message-Id: <6ofato$8js$1@taliesin.netcom.net.uk>
Hi, I've embedded a Perl interpreter in some C code I've written, which
is successful so far. However, I now want to dynamically load a module
from the Perl script I run, and there's one thing I'm not to sure on:
I've read the docs (in particular perlembed & Advanced Perl Programming,
chapter 19), which describe what I need to do in the way of calling an
xs_init() routine. So, what I've done so far:
$ perl -MExtUtils::Embed -e xsinit -- -o xsinit.c -std DBI
$ gcc -c xsinit.c `perl -MExtUtils::Embed -e ccopts`
So far so good. However when I try to link:
$ gcc -o myapp myapp.o xsinit.o `perl -MExtUtils::Embed -e ldopts`
I get:
[snip]
Undefined first referenced
symbol in file
boot_DBI xsinit.o
Now, boot_DBI is defined in <lib>/site_perl/sun4-solaris/auto/DBI/DBI.so.
What do I need to do to prevent a link error? Have I miscompiled Perl?
The output of "perl -MExtUtils::Embed -e ccopts" is (pardon the long
line):
-L/usr/local/lib /usr/local/packages/perl-5.004/lib/sun4-solaris/5.00404/auto/DynaLoader/DynaLoader.a -L/usr/local/packages/perl-5.004/lib/sun4-solaris/5.00404/CORE -lperl -lsocket -lnsl -lgdbm -ldl -lm -lc -lcrypt
This is perl5.004_04 on Solaris 2.6. Any advice appreciated.

I would suppose so, at least as long asnone of the filesystems were
NFS or CIFS.

It doesn't seem to be documented at all what unit the size is supposed
to be. Some experimentation shows that it seems to be bytes for all
systems I have easy access to, but I wouldn't like to rely on that
across platforms. It'd be interesting to hear what sort of thing it
returns on VMS or other systems with a different file-paradigm.

What else would it measure it in? Kilometres?

Oh no, Gigaquads.
I wonder what kind of Perl interpreter you could run on the USS
Enterprise (1701-D) Computer core. 'Unable to comply: $!' would probably
be wiped out as an error message!

Bits. Logical records. Disk blocks. Just to name the ones I could
think of in less time than it took to type the words.

Wow, they sure milk you for it.

I like the new Perl From The Ground Up book -- you might want to check
that out. It's so new I haven't actually reviewed it yet, but am
impressed so far. (All those years of writing "Perl!" on the
reader response card for Osborne books in the "what other languages
would you like us to cover" finally amounted to something...)

Sure, that's simple.

Oh, yeah. I've never even noticed that. Interesting.

Just curious, but why does it bother you so much. Once you even sent me
email correcting me because I had you last for Programming Perl. As if
that makes any difference.

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.
