New Website for Perl Beginners: perlmeme.org
Hi good people, there's a new web-site for Perl beginners - perlmeme.org - http://perlmeme.org/ It has Howto's, Tutorials and FAQs for Perl beginners - freely available and freely usable. Its mission ( http://perlmeme.org/start_here/index.html ) is: It's lots of ideas that together define why Perl is so different. It is the idea that there should be more that one way to do it, the idea that a language should make easy jobs easy and hard jobs possible, the idea that laziness, patience and hubris are virtues (for a programer). Perl itself is evolving at a rate unlike any other programming language. Those of us who use it for a living are excited by how powerful and expressive the language is and how close to the 'problem set' it is. With the development of Perl 6 well underway, the language is set to expand and take on even more functionality not found anywhere else. In our opinion, this makes it the language of choice for solving many of the software problems of the future. I have already contributed some code, text and ideas to perlmeme.org, but we could always use more help. If you have a document to contribute (even if it's already written), can provide feedback on the site, or can help in any other way, feel free to visit our developers' web-site: http://perlmeme-org.sourceforge.net/ Regards, Shlomi Fish - Shlomi Fish [EMAIL PROTECTED] Homepage:http://www.shlomifish.org/ 95% of the programmers consider 95% of the code they did not write, in the bottom 5%. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

Still, I agree with Randal, it seems obvious that links should be added to resources that will provide additional info on the subjects covered, and it would be difficult to do better than starting with http://learn.perl.org;. With that in mind I took a look at a Perl site I help run and found that much the same could be said for it, so I added the link there too. I do like the meme site though, and I believe it has the potential to become a valuable resource.

Yes, but it's pretty esoteric code. Why are you doing this?
I can't make this script work with use strict, always perl complains ?
If you REALLY want to use package variables instead of lexicals, then you
need to follow the instructions in the 'strict' documentation for
declaring your global variables:
use strict;
our ($foo, @foo);
$foo = ...;
@foo = ...;
testsub(*foo);
sub testsub {
our ($x, @x);

But this is really inadvisable. What is your motivation to do this kind
of thing?

Re: generating a wordlist from an array of arrays
mark berger [EMAIL PROTECTED] writes:
hey list. i stuck with gererating a wordlist from a changing
multidimensional array. each entry in the array contains a list with the
possible values.
fe:
@wordlayout = ((a, b),# possible values for 1st char
(c), # possible values for 2nd char
(d, e, f));# possible values for 3rd char
the following wordlist should be generated:
acd
ace
acf
bcd
bce
bcf
the only thing i came up with so far, is to generate some for loops
based on the array structure (how many chars, with how many posible
values) on fly and pass this to eval. pretty ugly (at least the way i
thought it out).
I gave that some thought. And I think it actually might be a good
solution. I wonder which method is more efficient, dynamic
code-generation or recursion?
Here is my try at it, does it look like yours?
@wordlayout = (['a', 'b'],
['c'],
['d','e','f'],
);
for my $idx ( 0 .. $#wordlayout ) {
# A loop for each level.
$code .= 'for my $char ( @{$wordlayout[' . $idx . ']} ) {'. \n;
# concat chars
$code .= '$str .= $char;'.\n;
}
# At the innermost level, extract a word.
$code .= 'push @list,$str;';
for my $idx ( 0 .. $#wordlayout ) {
# Remove this levels char on our way out.
$code .= 'substr($str,-1,1,);';
$code .= }\n;

BEGIN block question
Hello list,
I have some trouble understanding why a BEGIN block behaves the way it
does. Here are two files to demonstrate:
== test =
#!/usr/bin/perl
use warnings;
use strict;
use test2 qw($var);
our $var2 = 'second';
BEGIN {
print I see $var but don't see $var2\n;
}
= test2.pm ===
package test2;
use warnings;
use strict;
use Exporter;
our @ISA = qw (Exporter);
our @EXPORT_OK = qw ($var);
our $var = 'first';
1;
What makes the difference?
Thanks

Many thanks it works fine now (with print @x, \n; :-)) but local
disappeared.
I pick up this example in a tutorial (it is old but it exists and there are
many examples
and most of them are understandable (imho)) because I searched some example of
scripts
which used local. I encounter some problems to figure out local ;-)
for example, in perldoc -q dynamic, I found this example: (I changed it a
little...)
use warnings;
# use strict;
$var = 'global';
print in visible ;
visible();
dynamic();
lexical();
sub visible {
print \$var has value $var\n ;
}
sub dynamic {
local $var = 'local';
print in dynamic ;
visible();
}
sub lexical {
my $var = 'private';
print in lexical via visible ;
visible();
print in lexicale \$var has value $var\n;
}
output:
in visible $var has value global
in dynamic $var has a value local
in dynamic via visible $var has value local
in lexical via visible $var has value global
in lexicale $var has value private
if I want the result:
in visible $var has value global
in dynamic $var has a value local
in dynamic via visible $var has value local
in lexical via visible $var has value local
in lexicale $var has value private
I think that I have two ways:
With local:
..
use strict;
use vars '$var';
local $var;
.
without local:
..
use strict;
our $var = global;
.
Is it correct what I said ?

Re: BEGIN block question
Just to sum it up, so I make sure I got what you are saying. From the previous e-mail I understand that: * Right after the use xxx statement is parsed the corresponding module which is 'use'd is fully parsed AND executed. This execution includes any top level code not enclosed in subroutines and all subroutines referenced by said code, just like if we were to do 'perl file.pm' * Parsing of the original 'use'r code (even if there are BEGIN blocks defined firther in the 'use'r) continues only after the abovementioned parsing/execution is completed for the 'use'ed module and recursively any other modules it in turn might be 'use'ing. Is this correct? :) Thanks a lot Peter -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response

'use' and 'BEGIN' blocks are compiled by Perl before our().
So your script is compiled by the Perl interpreter in this order.
