Can I have the chance to see Perl6's official stable release in my left life? Regards, Ken Part of the issue is what do you determine as a release of Perl6 and what do you determine as stable? It is true that at the moment the Perl6 team do not call their releases the official first version because it hasn't yet met its language definition, and to me that's the point. Perl6 is a language definition, it is a standard that is being aimed for and one that has matured and evolved during its creation, we may never reach an end point to that but that doesn't mean you can't use Perl6 right now. You can use Perl6 projects such as Rakudo. Rakudo right now has stable point releases and is a long way towards a full implementation release of Perl6. Perl5 however is a language implementation. Perl5 has ported features from the Perl6 definition into itself and has continued to evolve with yearly point releases and a long term project to evolve the core. So why are you waiting to use Perl 6. You have implementations of Perl6 in you lifetime right now. You also have Perl5 which is widely used in development and deployment and is being evolved. As for the positive influence. Once, long ago Perl6 held up Perl5 development as people to my understanding went into a maint. mode waiting for Perl6. This ended and we have come a long way from then, I think that was around 5.8. Since then we have had major release of Perl 5.10 and moved onto a yearly schedule with 5.12 and 5.14. We also have projects such as Moose and its Roles which comes from perl6. 5.15 has been in the wild for 7 months or so and many of its features will make up Perl 5.16 and you can search for blogs (blogs.perl.org and ironman.enlightenedperl.org) to find info on the future evolution of Perl5 (I would follow the current PumpKing @rjbs (Ricardo Signes) as well as the previous Pump. Jesse Vincent who talk about this subject with far greater accuracy and understanding than I ever could. This argument about the implementation of Perl6, waiting, yada yada, is old. in fact it is about 4 years old and therefore stunningly out of date. It neither reflects or comments on the current situation with either Perl5 or Perl6 and their derivatives. Anyone indulging in it is to my mind mostly wasting their time and haven't engaged enough with the community to learn where we are. The best thing we can do is point them at the various newsgroups, irc channels, blogs and social media presences in the hope of bringing them up to date. If you want to contribute towards updating the Perl5 and Perl6 wikis etc. which are a cause of some of this cruft information then get in touch. Projects like Perl FAQs are already undergoing a major renovation and we have been redesigning many of the Perl sites. --By Mark Keating. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/

Re: Guidance for a New Programmer/Perl User

Rajeev Hi Rajeev, The idea is not to curry favour with one language or another, but help a person get on with what they're doing. If Mark needs to know Perl for his job, then I think we can safely assume it's Perl 5 that is being discussed. I don't think Shlomi meant to imply (or implied) P5 is a dead end—indeed, it's not—but that learning Perl 6, or some implementation (which may or may not end up being finished/abandoned/?), will not help Mark with his job. more interest towards php is not a valid concern because a) we're not trying to stop 'our people' going to 'their people', we're trying to help people get things done, and b) Mark didn't come to Perl, Perl came to Mark, so it's not like there's any worry that he'll choose something else. ;-) Best of luck to you all, Anneli From: Shlomi Fish shlo...@shlomifish.org To: Brendan bdgil...@gmail.com Cc: Rajeev Prasad rp.ne...@yahoo.com; Mark Tiesman mark.ties...@doit.wisc.edu; beginners@perl.org beginners@perl.org Sent: Thursday, December 15, 2011 2:45 PM Subject: Re: Guidance for a New Programmer/Perl User Hi Rajeev, On Thu, 15 Dec 2011 15:20:24 -0500 Brendan bdgil...@gmail.com wrote: How quickly Perl 6 knowledge can be put to good use probably depends on where you work.

Re: Guidance for a New Programmer/Perl User
Decades of programming in many languages have convinced me that Perl excels in every aspect. But I have to agree with Rajeev that Perl 6 has become a theory and needs evidence of practical application. In my mind there is no doubt of the benefits in Perl, but what place does it have?

New to Perl....
I am not sure where to post this but I would go straight to the point. I have been in the IT field for 5yrs working more as an Oracle developer . However, I just got a job as the Operations / QA manager. It's a new post and so am I kinda new to it. My boss has high regards for me and specifically requested I join the company despite my being novice to this post. I am expected to monitor the uptime, throughput; server log files etc. Look for respond to abnormalities; manage benchmark, manage hosting usuage and check websites for W3C compliance. (There is Linux, MySQL, Perl on all the servers). However, my boss just asked me for a flowchart / perl script to monitor the following:- -webserver, -Db server, -chat. Where do I start from... I have just 2 hrs to come up with the miracle solution I would appreciate any advice.. I forgot to ask for the necessary training I would need to fulfil my postion as Operation / QA Manager about from the book I have bought on Perl, Linux Admin as well as PHP MySQL - New Yahoo! Messenger with Voice. Call regular phones from your PC and save big.
Re: New to Perl....
Omabele, I'd say you need to determine the requirements (like what needs to be monitored), and then choose the tools best suited to meet those requirements. Chances are that Perl alone will not be the final solution to all of your monitoring needs. There are many freely available network and device monitoring tools, so there's really no reason for you to try to reinvent the wheel in two hours.

(There is Linux, MySQL, Perl on all the servers). Persoanlly, I'd start by breaking it all up into coherent chunks of tasks. Then for each task I'd see if a tool already exists and use that. There's likely modules related to the task at search.cpan.org you can use to create new tools if none exist. However, my boss just asked me for a flowchart / perl script to monitor the following:- -webserver, -Db server, -chat. Where do I start from...

Step one would be to reason with your boss that 2 hours is completely unreasonable to make such a system, even if you'd personally designed the network and new ever inch of it like the back of your hand. If your boss still expects a two hour solution you have 2 options: a) google for tools that do all of the stuff you need b) tell your boss he's friggin' idiot and walk out :) Step two is the process I outlined above.

Help with split Was Need RE. New to Perl
Hi All,
Many thanks to Jay for his examples I have now written a perl script that is
munging a text file. Eventually I will move the perl code into a function
inside a postgresql database.
I am processing inputs like the following:
815 HTPP Black 2in sq Border: RMFP025BK Size: 7'10 x 16' Tag: None
3000 HTPP Black 4in sq Border: WNY200BK Size: 17' x 50' Tag: None
3000 HTPP Black 4in sq Border: WNY200BK Size: 12' x 12'2 Tag: None
Netform Lily Pad Net Size: 5' X 32' W L Body Length:24'
250 HTPP Black 1in sq Border: TW84NTBK Size: 9' x 25' Tag: 200' sec
1250 HTPP Yellow 2in sq Border: None Size: 6'1 x 12'7 Tag: 1855mm x 3840mm
Here is the code that I have written so far.
#!/usr/bin/env perl
use strict;
use warnings;
open(INFILE, input.txt) or die Can't open input.txt: $!;
while (INFILE) { # assigns each line in turn to $_
my $v_border_id = ;
my $v_size = ;
my $v_length = ;
my $v_width = ;
my $v_tag = ;
# Echo out the input line.
print \nInput line:\n $_;
# Perform a case insensitive check for the proper data format.
#if (/(?i)border:.*size.*tag:.*/){
# Perform a case insensitive check for the proper data format.
# Capture the desired parts of the data using parentheses.
if (/(?i).*border:[ ]*(.*)[ ]*size:[ ]*(.*)[ ]*tag:[ ]*(.*)[ ]*/){
print properly formatted\n;
# Check for no border.
if ($1 =~ /(?i)none/){
$v_border_id = ;
} else {
$v_border_id = $1;
}
# Parse up the size string.
my ($v_length, $v_width) = split(/x/, $2);
print split(/(?i)[ ]*x[ ]*/, $2);
print \n;
# Check for no tag.
#if ($v_tag =~ /(?i)tag:[ ]*none/){
if ($3 =~ /(?i)none/){
$v_tag = ;
} else {
$v_tag = $3;
#$v_tag =~ s/.*(?i)tag:[ ]*//;
}
} else {
print bad format\n;
$v_border_id = ;
$v_size = ;
$v_tag = ;
}
print Border ID: $v_border_id\n;
print Size string: $2\n;
print Length string: $v_length\n;
print Width string: $v_width\n;
print Tag string: $v_tag\n\n;
}
close INFILE;
Most of the code seems to be working as expected. I seem to be having a
problem with the split command/assignment as the length and width strings are
blank. The command is based on Jay's example shown here.
my ($length, $width) = split / x /, $size ;
What I really wanted to do was this.
my ($v_length, $v_width) = split(/(?i)[ ]*x[ ]*/, $2);
So I put the following in the code to try and understand what was going wrong.
print split(/(?i)[ ]*x[ ]*/, $2);
print \n;
When I ran the program this is one of the outputs
Input line:
1250 HTPP Yellow 2in sq Border: TW84NYYL Size: 4'11 x 6'1 Tag: 1500mm x
1855mm
properly formatted
4'116'1
Border ID: TW84NYYL
Size string: 4'11 x 6'1
Length string:
Width string:
Tag string: 1500mm x 1855mm
What am I doing wrong?
Kind Regards,
Keith

[snip]
Well, it looks like the immediate issue here is that there is no $2.
The match variables, including $1, $2, etc. are reset /every/ time you
run a regex, whether you use them or not..
'if ($1 =~ /(?i)none/){'
undef'd $1, $2, and $3 so it could reuse them, and then didn't reload
them. The match variables are /very/ temporary; if you're not going
to use them immediately, assign them to a temporary variable.
Also don't complicate your code unecessarily: if you're never going to
turn off case sensitivity (i.e. with (-?i)), just use /none/i instead
of /(?i)none/. Your eyes will thank you in the long run.

that is munging a text file. Eventually I will move the perl code
into a function inside a postgresql database.
I am processing inputs like the following:
815 HTPP Black 2in sq Border: RMFP025BK Size: 7'10 x 16' Tag: None
3000 HTPP Black 4in sq Border: WNY200BK Size: 17' x 50' Tag: None
3000 HTPP Black 4in sq Border: WNY200BK Size: 12' x 12'2 Tag: None
Netform Lily Pad Net Size: 5' X 32' W L Body Length:24'
250 HTPP Black 1in sq Border: TW84NTBK Size: 9' x 25' Tag: 200' sec
1250 HTPP Yellow 2in sq Border: None Size: 6'1 x 12'7
Tag: 1855mm x 3840mm
Here is the code that I have written so far.
#!/usr/bin/env perl
use strict;
use warnings;
open(INFILE, input.txt) or die Can't open input.txt: $!;
while (INFILE) { # assigns each line in turn to $_
my $v_border_id = ;
my $v_size = ;
my $v_length = ;
my $v_width = ;
my $v_tag = ;
# Echo out the input line.
print \nInput line:\n $_;
# Perform a case insensitive check for the proper data format.
#if (/(?i)border:.*size.*tag:.*/){
# Perform a case insensitive check for the proper data format.
# Capture the desired parts of the data using parentheses.
if (/(?i).*border:[ ]*(.*)[ ]*size:[ ]*(.*)[ ]*tag:[ ]*(.*)[ ]*/){
print properly formatted\n;
# Check for no border.
if ($1 =~ /(?i)none/){
$v_border_id = ;
} else {
$v_border_id = $1;
}
# Parse up the size string.
my ($v_length, $v_width) = split(/x/, $2);
print split(/(?i)[ ]*x[ ]*/, $2);
print \n;
# Check for no tag.
#if ($v_tag =~ /(?i)tag:[ ]*none/){
if ($3 =~ /(?i)none/){
$v_tag = ;
} else {
$v_tag = $3;
#$v_tag =~ s/.*(?i)tag:[ ]*//;
}
} else {
print bad format\n;
$v_border_id = ;
$v_size = ;
$v_tag = ;
}
print Border ID: $v_border_id\n;
print Size string: $2\n;
print Length string: $v_length\n;
print Width string: $v_width\n;
print Tag string: $v_tag\n\n;
}
close INFILE;
Most of the code seems to be working as expected. I seem to be
having a problem with the split command/assignment as the length
and width strings are blank. The command is based on Jay's
example shown here.
my ($length, $width) = split / x /, $size ;
What I really wanted to do was this.
my ($v_length, $v_width) = split(/(?i)[ ]*x[ ]*/, $2);
So I put the following in the code to try and understand what
was going wrong.
print split(/(?i)[ ]*x[ ]*/, $2);
print \n;
[snip]
Well, it looks like the immediate issue here is that there is no $2.
The match variables, including $1, $2, etc. are reset /every/ time
you run a regex, whether you use them or not..
'if ($1 =~ /(?i)none/){'
undef'd $1, $2, and $3 so it could reuse them, and then didn't reload
them. The match variables are /very/ temporary; if you're not going
to use them immediately, assign them to a temporary variable.
Also don't complicate your code unecessarily: if you're never going
to turn off case sensitivity (i.e. with (-?i)), just use /none/i instead
of /(?i)none/. Your eyes will thank you in the long run.
HTH,
--jay
Okay that makes sense. But if that is what is happening then
how come the print statement operating on $2 works just fine?
I appreciate the comment on the i modifier. I didn't realize
that case sensitivity could be turned off and back on within
an expression. Not knowing what the bloody users are going
to do I like to have it off all the time.
Kind Regards,
Keith

Sorry, not enough coffee. $1, $2, etc. actually stay set until
they're unset, and the scoping is working in your favor here,
although you'll notice all of the use of uninitialized value errors
on your last set of splits. Using them at any distance from the
regex that produced them, though i still likely to produce
unexpected results. Also, your variables aren't scoped proberly
either. You're declaring them with my inside an if block, and then
trying to print them outside.
my ($v_length, $v_width) = split(/(?i)[ ]*x[ ]*/, $2);
defeats the purpose of predeclaring the variable. The second my
rescopes both variables to the enclosing block. The effect here is
roughly the same as 'local'.

Is this the data you expect to get out of the database...or data from
somewhere else that you're going to insert into the database...or...?
Becuase at the moment it doesn't really look like a database problem.
We need some more here, including some sample code. What are you
doing, and where is it going wrong?
As far as quickstarts go, for database work, the two sources Chris
mentioned are really the place to go. For a general perl
intoductions, the first place to go is perldoc perlfaq, man perl, and
perldoc perlintro, and the best printed resourse is by far _Learning
Perl, 3rd Ed._ from O'Reilly. It's short and shout get you up and
running in about a day, depending on your general programming ability.
As for your specific question, you'll want to use some kind of regex.
The following should give you some ideas and show a fairly perlish
appraoch to variable declarations, but this is just an example. The
perl motto is There's more than one way to do it. How you end up
storing the data into variables will hopefully be deterined by what
you ultimately want to do with it.

Jay,
Thanks very much for your post.
I have been banging my head against the wall and based on what I have been
able to read in the last hour or so I have come up with the following code.
#!/usr/bin/env perl
use strict;
use warnings;
open(INFILE, input.txt) or die Can't open input.txt: $!;
while (INFILE) { # assigns each line in turn to $_
my $v_border_id = $_;
my $v_size = $_;
my $v_tag = $_;
# Echo out the input line.
print Just read in this line: $_;
# Print out the border.
if (/(?i)border:.*size.*tag:.*/){
print properly formatted\n;
$v_border_id =~ s/.*(?i)border:[ ]*//;
$v_border_id =~ s/[]*(?i)size:.*//;
print Border ID: $v_border_id;
$v_size =~ s/.*(?i)size:[ ]*//;
$v_size =~ s/[ ]*(?i)tag:.*//;
print Size string: $v_size;
$v_tag =~ s/.*(?i)tag:[]*//;
At the moment I am just processing a text file to get the hang of how to munge
data with perl. Eventually I will be creating a function inside a postgresql
database. It sort of works like this:
CREATE OR REPLACE FUNCTION interface.func_parse_description(varchar)
RETURNS varchar AS
$BODY$
perl statements
$BODY$
LANGUAGE 'plperl' STABLE STRICT;
If your curious this page will give you more details about what I am trying to
do. http://www.postgresql.org/docs/8.0/interactive/plperl.html
I can see from your post that there are lots better ways to accomplish what I
need. Although at the moment the example you sent is largely beyond me I will
try to implement some of your suggestions and see what happens.
Kind Regards,
Keith

What you are seeking to do is essentially this: move the first file to a temp file: mv file1.ext /tmp/file1.ext move the second file to the first file: mv file2.ext file1.ext move the temp file to the second file: mv /tmp/file1.ext file2.ext You can do this with a system call for each of the moves. Extensions and names won't matter, as you will be giving them the name and extension when you do the moves. I'd help with the code snippets, but I am in PHP mode and my perl is weak at best...

Hello,
I am not sure, why you want to 'do Nothing' about the contents of the file. if
you change gif to jpg, it will conflict the formats.
Try this for just changing names:

Subject: New to perl ...
Hello,
I would like to swap the file name only and not the extension or the
content.
Example:
There are two file : 1.jpg and 3.jpg
output = 1.jpg becomes 3.jpg and 3.jpg becomes 1.jpg
OR
1.jpg and 3.gif
output = 1.jpg becomes 3.jpg and 3.gif becomes 1.gif
here we are changing the name only and not the extension.
Inside my program I don't know either files extension, but they will be only
jpg or gif
Any help...

But I was asked not to confuse...
So ignore this posting...
no i am not going to ignore it :-)
tell me what exactly have you accomplished and what questions have you
answered? my statement is:
you can never code a 3-way logic in Perl
and then you post a bunch of code without any comment at all except telling
people to ignore your code. thus, i assume your code answer my question and
prove that you can code a 3-way logic in Perl which means:
* Perl's 'COND ? THEN : ELSE' conditional operator should never be used
because it only handles a 2-way logic: true or false
* Perl's equality and inequality operators such as ==,!=,eq,ne should never
be used because it only handles a 2-way logic: it evaluates their operants
and produce either a true or false value
* You should never uses 'if(COND)' in Perl because it only evaluates COND to
either true or false and NOT a 3-way logic as true,false or neither true
nor false
* You should never uses 'unless(COND)' in Perl for the same reason that it
only handles a 2-way logic and evaluates to either true or false and
nothing else
* You should never uses 'EXP or EXP','EXP and EXP','EXP EXP','EXP || EXP'
in Perl because they only evaluates to true or false
* More importantly, given this simple program:
#!/usr/bin/perl -w
use strict;
my $i = $ENV{something} ? 1 : 2;
__END__
* I say $i is either 1 or 2 because $ENV{something} can only be true or
false
* You *might* be saying $i is unknown (or undef) because $ENV{something} can
be true, or false or neither true nor false which '?:' can't handle.
correct?
* finally, how useful is this:
($test) ? print \$test exists
: ($test 0) ? print \$test greater then zero
: ($test 0) ? print \$test less then zero
: print \$test is zero;
if $test is neither true nor false?
* do you realize $test is evaluated to either true or false?
* do you realize $test 0 is evaluated to either true or false?
* do you realize $test 0 is evaulated to either true or false?

No. Can undef ever be true? If not, it necessarily is false, which
means it is not an independent condition.
The closest you could get would be 0 but true but then you are still
only close (and not close enough)...

yes but is undef true or false? and when you evaluate undef as a boolean
expression, what possible values can it has? i say:
* 2 possible values: true or false
your previous posts sound like:
* 3 possible values (3-way logic): true or false or neither true nor false
and my very original quesiont is:
show me an expression where it can be evaluated to neither true nor false

Hello Bajaria,
if the web site request ($ua-get()) fails $response-is_success will be
false. By false I mean it isn't set to 1 which equals true. In your above example you
would end up in the 'else'-block.
To find out which error occured you need to take a look at $response-code.
The number found in $response-code is in the range from 100 to 599. You can find more
about these return codes by visiting
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html.
To get a short human readable message about the meaning of $response-code
take a look at $response-message.
You can find out much more by entering the following line at the command
prompt (or the terminal):
perldoc LWP::UserAgent
perldoc HTTP::Response

Anyways, why do u have to assign to a var and print ?
Okay... the use of the $request hash variable was just an example. Yours should be
$response-content, following your earlier example:
See the following example:
---example start---
#!/usr/local/bin/perl
use warnings;
use strict;
use LWP::UserAgent;
my $ua = LWP::UserAgent-new;
my $response = $ua-get( 'http://www.cnn.com/' );
if ( $response-is_success )
{
print Content:\n.$response-content.\n;
}
else
{
print Error:\n.$response-message.\n;
}
---example end---
You have to use the dot-concatenation or save the result of $module-function into a
variable because it, in your case $response-content, isn't a variable. It is a
function that returns a variable. Because of that perl just prints the memory address
of the modules data structure in your memory if you try to let perl do the string
substitution for you.
/oliver/
BTW.: You might also just try to enter
perldoc perl
at your terminal prompt.

Hi,
This is my first email to beginner's Perl and sincerely hope I am sending
this message to the right place.
I want to delete some DB backup files using UNC pathing and perl. My code
segment, which does not work, is listed below. I do not get any errors when
I run this piece of code however, the files are not deleted either. Does
anyone know what is wrong with the code? The file permissions are open to
the world, the file was not in use, and I did try using
(myserver\\e$\\LS_DbBackUp\\stdby30dev\\*.trn
file:///\\myserver\e$\LS_DbBackUp\stdby30dev\*.trn ).
What I found out so far is that my code works with Perl version 5.005_03,
binary build 522 but not with ActivePerl-5.6.1-535-MSWin32-x86.msi or
ActivePerl-5.8.0.806-MSWin32-x86.msi. Has anyone else come across this
issue? What did you do to resolve it?
Code segment
foreach $file (myserver\\e\\LS_DbBackUp\\stdby30dev\\*.trn

You probably also want to take a look at O'Reilly's Learning Perl (By Schwartz Phoenix). If you have previous programming experience you could probably go through it in a couple of days to get a feeling for the language. After that, the Camel will give you all the details, whereas the Cookbook is invaluable for solid example code. If you have the choice between Unix/Win32 platforms, pick the one that you will be developing for after you mastered the language. Perl is available for both, and although a lot of it is platform independent, there are some differences. -- felix -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
