Bzzt! There ARE differences, but this one isn't that relevant!
Try this:
# file Say/Hello.pm
sub hello {
my $name = shift;
print "Hi, it's $name!\n";
}
1;
save as "Say/Hello.pm" somewhere in @INC.
Main:
require Say::Hello;
hello('Bart');
-->
Hi, it's Bart!
Bugger that!
The main difference between "require" and "use", here, is that use()
works at compile time, so it allows a more flexible syntax than
require(); or use() in an eval string, for that matter!
use Say::Hello;
hello 'Bart';
Because of the "use", Perl knows about the sub "hello", and so
"hello 'Bart'" is recognized as a sub call. It won't work with
require(), except maybe if you predeclare the sub:
sub hello; # necessary...
require Say::Hello;
hello 'Bart'; # if you want this syntax!
In short: you may need to (slightly) adjust the syntax, if you want to
use require() (plus "import") instead of use()...

Subject: C padding/Perl unpacking question
Message-Id: <wkwvu1jxd3.fsf@octel.com>
I have to write some CGI scripts to interface with a legacy C program
with a bunch of C data structures.
One of the issues that i'm facing is how to recognize the C
padding pattern and adjust for it accordingly in my unpack template.
Currently, my way of dealing with this is by eyeballing the hex dump
of my C structure and visually determine the amount of padding that the
C compiler does to the data structure, i'd then compose the Perl's "unpack"
template accordingly.
My question is does anybody have a tool that will help me with this
job?
Thanks in advance.

If you're on a unix machine, then you don't need any specific
extension. In fact, you don't even need an extension at all. Despite
that, all of my Perl scripts have a .pl extension, so that I would
know that this is a Perl file without more()ing it.
If you're on a winblows machine, then you probably need the .pl
extension since this associates files with the Perl interpreter. Of
course, you can associate the Perl interpreter with another extension
(like .cgi for example), but then you are just confusing yourself.

Build mod_perl - it will build apache for you if you ask it to. All this is
in the readme and install files for the mod_perl distribution. Check those
out first - there's no way you'll do anything with mod_perl unless you read
the docs that are supplied.

You are of course entitled to your own points of view, but statistics
speak louder than words. Read lwall's 3rd state of the onion.
It is funny that you think Perl doesn't serve any purpose any
more. The way I see it is that Perl was made to fill an empty gap, and
it did so beautifully. Other languages, on the other hand (like
Python, for example), was written for the sake of writing yet another
language (IMO of course). So, when I started to read about Python I
thought "Hmm .. this language serves no purpose at all!"

Hmm, a -w error with no -w on the shebang line! That means your script
was not -w safe and your new perl must be run through a server or a
batch file or something that automatically adds -w. This means you will
have to check all your scripts to make sure all variables are
initialized, not a bad thing in the long run.

From the Perl Embed documentation:

perl_construct(my_perl) ;

This generates 119 Purify errors:
array bounds read,
array bouhds write,
uninitialised memory read,

444 leaked bytes
these errors all stem from the perl_parse() function.
I'm using Perl headers:
from perl5.005_02/lib/5.00502/sun4-solaris/CORE
Any suggestions ?
Perl is in a pretty sorry state of affairs if it contains these
type of errors - and in large quantities. And - note I only called
perl_parse with NULL arguments .... heaven knows how much junk I'd
be exposed to if I called the function with real arguments.

Yes, and that's my point.
I use the fairly complete syntax highlighting of Ilya's "cperl-mode"
in GNU Emacs.
On rare occasion, I must change the code I write so that it doesn't
confuse cperl-mode, so that cperl-mode doesn't continue to confuse me.
This does not seem right, and I know Ilya's pretty familiar with Perl
syntax, and with GNU Emacs, so I don't give much hope for other tools
out there. It might work on trivial stuff, but I don't write any
trivial Perl code anymore. :)

If the Perl syntax highlighting in UltraEdit-32 isn't complete,
it's easy to make it so (and your fault if you don't). It's
controlled by a simple-to-edit text file. (There were a couple
of shortcomings in the stock file, but fixing that only took a
few minutes.)-Wm

Sure.
Go to www.apache.org and look at, you guessed it, the FAQ!
http://www.apache.org/docs/misc/FAQ-F.html#premature-script-headers
BTW -- there's a usenet group that deals with CGI issues -- and that
topic is currently being discussed (and it's always being discussed
there).

This indicates that your program is either terminating, or producing output
that is not a valid header, before it produces some output that _is_ a valid
header.
This may or (more likely) may not be to do with Perl. If your script runs
without errors from the command line it almost certainly isn't a Perl problem.
I would suggest this is a CGI or HTTP problem, or a problem with NT recognising
perl scripts and executing them properly.

This isn't the best group to ask this sort of question,
comp.infosystems.www.authoring.cgi covers CGI issues and
comp.infosystems.www.servers.ms-windows covers server configuration.
This could be caused by a number of problems, without seeing the script
I can only offer two suggestions;
1) Firstly can you run the script from the command line? Does it work?
2) Add the line;
use CGI::Carp qw(fatalsToBrowser);
to your script, if the script is failing it will hopefully give you the
line no. and more of an idea what the problem is.

That is, sadly, only too true. Some months are more September than

This is not a problem with Perl, and is unlikely to be a problem with your
perl script. It is likely to be a problem with NT, your web server, and the
way either or both of those are configured. Please ask your question in groups
that deal with NT web servers.

Subject: variable globalisation
Message-Id: <qg01zc9bfmu.fsf@chico.cstr.ed.ac.uk>
I would like to use several modules "Mod_a.pm", "Mod_b.pm",
"Mod_c.pm" by using one generalising module "All.pm" which looks
like:
package All;
use strict;
use vars qw(@ISA @EXPORT);
use Exporter;
@ISA = qw(Exporter)
use Mod_a;
use Mod_b;
use Mod_c;
But when I specify only "use All;" in a perl script, that script does
not recognise global variables specified in each embedded module. For
example, "Mod_a.pm" could be like:
package Mod_a;
use strict;
use vars qw(@ISA @EXPORT $var);
use Exporter;
@ISA = qw(Exporter);
@EXPORT = qw($var);
$var = "something"; ## $var is globalised, isn't it?
In a script I can retrieve the value of $var if I specify the line
"use Mod_one;" but I can't, if I specify only "use All;" instead. Why
not? How are the global variables made inherited across other
modules?
Thanks,
Tae

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

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" from
almanac@ruby.oce.orst.edu. The real FAQ, as it appeared last in the
newsgroup, can be retrieved with the request "send perl-users FAQ" from

The "mini-FAQ", which is an updated version of the Meta-FAQ, is
