Re: Modules
I use modules for complex things that I might get wrong. To re-use other people's code is often better than to re-invent their solutions. https://metacpan.org/pod/WWW::Mechanize::Examples has some good examples of useful scripts that are short and simple. Imagine how hard it would be to write the same scripts without the module. When I have an issue that I think others must also have faced, I look for a module to solve the issue. But I am critical to modules that are outdated/abandoned, heavy with many dependencies, or unproven with few downloads etc. I also remove modules when I no longer need them.

In this particular case BEGIN comes first and simply tells Perl to
look at /special and /special/packages BEFORE looking anywhere else
for the packages you wish to use in your various projects.
You still need to make sure the proper functions/sub-routines are
exported so that your code is called in preference over the Perl
code.
However, if you wish to control what is required -- say branch
logic, you will need to stick with te 'require' directive as use
packages referenced will always be brought in even if they are not
called.

Re: Modules inter-relay ?
From: Mug [EMAIL PROTECTED] Say I have 2 modules ( below pseudo codes ) , which the first package ( InitGlobal ) will be used through out the other project modules. However, InitGlobal itself would relay on some other modules, which the modules using InitGlobal too. This sometimes caused some weir problem, or perhaps it just runable with luck. So I have to fix it one by on with to cutting some shareable code to another .pl file with require() to call them, but sound quite terrible enough. Not sure how do Perl handle this, or is that any standard way for module inter-relay ( or Is that any formal term to call this ? ) So you have two interdependend modules, right? A uses stuff from B, B uses stuff from A. You should reorder your code to prevent this. And if the two are too intertwined to do that, put them both into the same file.

You can place the special packages in their own directory and point to it:

Thank you very much Bill,
But may I ask a bit further because a bit can't get what should in terms
of 'special'
and what should in terms of 'their' and this piece of code should put to
where ? ( self
use or in the other all packages )
And if I didn't get mis-understood on what I've studied, 'use' still
comes earlier than
'BEGIN{}', so what is the mystery why this method can do that ?

RE: Modules aiming at displaying mathematical functions on screen?
After searching the cpan.org site for mathematical modules, I did not find a module which can display graphically the result of a function. I want to see a function curve displayed in a graphical window? How can I make it possible in Perl? Thanks in advance for your help. Module names in quotes: You could build a perl Tk application - it comes with an example related to your query. You could use GD or Imager or Image::Magick to plot pixels and save as various graphics formats. (The latter also exports LaTex, I believe).

Re: modules - lost again
Examine your concept of reside in. You appear to be confused with modules that use the Exporter. You don't. I believe you'll find that you use SomeOther::Module *before* using Configuration in the main program, which means that the assignments haven't taken place yet. A-ha! Some days I am dumber than other days :) Everything was exactly as you described. In this light I have a couple of additional questions. This one is about my Tools.pm which uses Exporter and delivers a set of 5- 10 line subroutines for stupud tasks (number rounder, strip commas from numbers, commify them back, customized html entity decoder etc etc etc). What I am currently doing is automatically exporting ALL these subroutines (using fairly descriptive names to avoid clashes) and use Tools; in all modules that might benefit from them. Pretty standard. However I do not understand if importing just a subset of just the necessary functions is beneficial in terms of speed. What I am thinking is that since every single function IS going to be used sooner or later by at least one of the modules, and since EVERY module is called at least once from the main program over its runtime - the entire Tools.pm is being processed anyway and wether I import all functions or just a few makes no difference on the entire picture. Or am I wrong? And if I am, and specifying explicit imports for each module is beneficial - is Autoloader applicable to this situation? I've seen tons of examples of how OO can benefit from calls to non-existent instances, but I didn't see a single usage of Autoloader in a non-OO envirnoment which leads me to believe that it is not applicable.

Confused. The first use Tools will load Tools.pm and cause *all* of the
subroutines to be compiled. Subsequent use Tools won't load Tools.pm
because it's in %INC; but, like the first time, *will* call Tools-import().
That call will result in the names being exported. Observe:
% cat foo
#!/usr/bin/perl -l
use Bar;
use Foo;
% cat Foo.pm
package Foo;
use Bar;
1;
% cat Bar.pm
package Bar;
sub import { print Bar import }
print Bar load;
1;
% ./foo
Bar load
Bar import
Bar import
And if I am, and specifying explicit imports for each module is beneficial -
Not for reason of speed. For reason of maintainability. You should only
import names you are going to use, and then do so explicitly, so that a
maintenance programmer doesn't look at the program wondering where
thunk_widgets() has come from. The exceptions to this rule are few and
far between.
is Autoloader applicable to this situation? I've seen tons of examples
of how OO can benefit from calls to non-existent instances, but I didn't
see a single usage of Autoloader in a non-OO envirnoment which leads me
to believe that it is not applicable.
I think you're confused again. If AUTOLOAD() exists in a package it will
be called when a non-existent function is called in that package. Doesn't
matter whether or not it's O-O. It isn't going to help you. I assume you
meant non-existent methods, because non-existent instances is an
oxymoron.
Autoloader.pm allows you to put subroutines in a data block so they are
only compiled when needed (the autosplit function must be used to copy
them to individual files). I've never used it with the Exporter and don't
know what would happen; at worst, though, you might need to declare stubs
in the main body and then suppress redefinition warnings in the individual
definitions.
Given the case you describe though, I can't see it making any measurable
difference in performance. If you really need to speed things up there
are more appropriate ways of doing it. If you don't know you need to
speed things up yet, don't throw wacky devices at the code thinking
they're doing any good :-)
There's more I could say, but I already wrote large parts of a book about
it :-)

You get the idea. Now I am able to access them from Main by doing:
use Configuration;
my $whatever_reference = $Configuration::auth{mmv}{tbt};
however if in main I have another module:
use SomeOther::Module;
then from within this module the same variable returns undef. I suspect I
can not do this since the scopes differ,
Not the problem.
but I am using fully qualified
variable names. Another way would be to use Configuration in the very same
module, however then Configuration.pm got to reside in the main dir AND a

True :-)
Is what I am trying to do even right
from a good programming point of view? Probably the total amount of modules
accessing these Configuration variables will be around 10. I would highly
appreciate any input on this.

What you're doing is reasonable. And you can 'use Configuration' from all
of the other modules if you want; it will only be loaded once, after that,
its name in %INC will prevent it from being loaded unnecessarily.

since the

That way it will be compiled early and so you can

yes, one can do the reset back to package main.
part of the reason I opt for the
BEGIN { package }
approach is so that I know that the compiler
will deal with the BEGIN { BLOCK } before
worrying about anything else in the code.
That way I know that my objects will be sorted out foist.
As a general rule of thumb, though, once I have played
out an idea then it is going off to it's own
Monkey.pm
file where it is a fully externalized perl module...

sorry interrupted. Allow me to illustrate a bit better

So we start the Module off with
package OurModule
VERSION = 1.01; # since you will have finished beta on it
sub new
{
my $type = shift;
my $class = ref($type) || $type;
my $self = {};

# the subs go here
#
sub my_first_sub {
my $me = shift; # to get the reference

Then each of the two cgi scripts can do the simpler
use lib ../lib/;
use OurModule;
...
my $obj = new OurModule;
...
my $first_thingie = $obj-my_first_sub(@arglist);
and one is out and away... No Mus, No Fuss.
Ok, so you COULD have done the Dilbert Class Solution of
use lib ../lib/;
use OurModule;
...
my $first_thingie = OurModule-my_first_sub(@arglist);
...
Which ever makes you feel happier.
I would of course HIGHLY RECOMMEND that you get
Schwartz's Learning Perl Objects, References Modules.
cf: http://www.oreilly.com/catalog/lrnperlorm/
for all the detail clarifications that are useful
above the standard
perldoc perlsub, perlmod, perlmodlib
The alternative to that is to have some funky interface
into the script with the function that will understand
that it is being called in some weird way that it should
pass the data to the function, and then return it out,
oh, say STDOUT. Trust me it can be done, but it is such
an ugly path that it should be left for the strictly
obfuscatory Perl Contest.

I know the modules are good since I have no problems calling their methods if I use them individually. But whenever I use both in my driver script one of them has to have its functions proceeded by the module name. There is no name clashing in variables or function names.

more info available at perldoc perlvar
a quick deconstruction:
@: this is an array
INC:short for include
hence the array of thing we may need to go to for includes,
eg: all the default -Iinc_dir stuff.
Try to remember that the
use FOO::BAR
merely 'reads the include' as it were and 'imports'
any reference to things in the FOO::BAR module
As is noted - the base @INC is compiled into perl - and
there is a reasonably standard hierarchy about how things
should hang below that level.
As also noted the traditional ways of manipulating it are
a) the use lib token; pragma
b) the '-Idir' command line option
for fun tried to programme that in
#!/usr/bin/perl -I'path_to_lib' -w
but that did not work
c) set the Environmental variable LIB5PERL
which is useful if you find that you are installing
into non-standard directories such as
$ENV{HOME}/lib/perl

We choose to manually install our modules for all of our environments. The CPAN module has a tendency to grab the latest and greatest of everything. One nice thing is to use the CPAN.pm to make a 'snapshot' of your modules and make a bundle out of them. Then just install your custom bundle.

Got a long list of stuff, and wanted to write to a file,
What did I miss here? (almost there...)
Redirect:
find `perl -e 'print @INC'` -name *.pm -print modules
#!/usr/bin/perl
@array = (test,dave);
push @array ,`find @INC -name *.pm`;
open (ML, modulelist) or die could not write file $!;
while (@array){
print $_\n;
}
Er, just stick the module list in a file from the command line, no need to
write a Perl script to do it. Then clean it up with an editor.
If you're looking for more details, autobundle is the way to go; it will
tell you version numbers. CPAN.pm can even tell you which modules have
more recent versions available.

RE: Modules question
put use (MODULE NAME); at the top of the script. Run the script and see if it generates an error. e.g use Win32::Lanman; -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: 29 June 2001 13:36 To: [EMAIL PROTECTED] Subject: Modules question Help with Modules please.

Re: Modules question
Hi Anna, To find out all the modules installed on your system, refer to the following URL: http:[EMAIL PROTECTED]/msg04057.html To find out about a single one, you can do: perl -MMODULE_NAME -e 1 So, to see if CGI.pm is installed: perl -MCGI -e 1 If you see no error messages, it is installed, if you do.. it isn't.

Re: Modules (was: Require)

It's always seemed to me that the 'approved' way of creating modules
to import routines into another script was a bit wordy.
In a nutshell, you have to do something like
package abc;
use Exporter;
@ISA = qw(Exporter);
@EXPORT = qw(foo bar baz);
@EXPORT_OK = qw(blech flurble);
sub foo { ... }
And that's not even with proper strictness enabled.
But you don't *have* to do any of that.
Exporter is often only use to pollute the main package namespace.
It's an awesome module, but almost never something you *have* to use.
You can always just specify the namespace where the functions reside.
That said, I might agree that require is a better mechanism in many
cases, but when I first started looking for ways to modularize my code,
I looked at require in perlfunc and saw:
For a yet-more-powerful import facility, see use and perlmod.
Being too much the gearhead, I went straight there and have virtually
never used a require statement in a script.
