It is misleading to suggest that Perl on Unix is fine, and Perl anywhere else is risky. It is usually a simple matter to write portable software, as described in perldoc perlport snip Alright, I have to call bull on this. There are a total three functions that may not behave in the expected way between the UNIXes: atan (HPUX does some non-standard things), sockatmark (it is fairly new and may not exist on some UNIXes), and system (Does not automatically flush output handles on some platforms). Compare that to Win32; I lost count of the caveats and warnings after thirty or so. The big ones being fork, open, and kill. fork() and kill() is just as OS specific as Win32::Process is. One just got a builtin, the other did not. One presents itself as if it was general, the other says clearly it's OS specific. If you wrote a list of caveats from the point of a Win32 developer it would be just as long. And would list the same things, just with different wording. fork() is not THE or even THE ONLY way to create processes, it's THE UNIX way to create processes. I wasn't claiming that UNIX was the only way. I was calling bull on Rob's claim No, not all Perl functionality works on all Unix platforms. You are as likely to find a compatibility issue moving from one Unix to another Unix as from Unix to, say, VMS or Windows. Then start to look at what modules simply won't work on Win32 due to the lack of supporting libraries. If you start your development on Unix, you notice the modules that work under Unix and do not under Win32 and never even notice those that work under Win32 and not under Unix. Besides, those that are Win32 specific prettymuch always say so in the name. The unix ones do not bother. Everyone's using Unix and if he doesn't he bloody well should! Well, I am a UNIX bigot, but the Win32 modules are tied to one OS (well, one that is still in common usage, three in total), the modules you are referring to work across many OSes; however, many of the them require third party libraries that are simply not available on the Win32 platform, that is not a problem with the module, it is a problem of lack of availability of the library. Now I need to see if some of the Win32::* modules work with wine. I have moved Perl scripts amongst HP-UX, AIX, Solaris, multiple flavors of Linux, various BSDs, OS X, and probably a couple I am forgetting and never had to change anything but a few arguments to external commands. I have also ported Perl code to a few Win32 platforms (Win9X, WinNT, and WinXP) and it was generally an uphill fight (mostly due to the lack of support for modules, but also because of the whole drive letter crap). I've moved between California, Colorado, Kansas, North Carolina, Massachusetts and probably I couple I am forgetting and never had to change anything but a few addresse for snailmail. I have also visited France and it was an uphill fight. My gosh them bastards speak french! Exactly. Moving between UNIXes is easy (like moving between states in the US). Moving outside of UNIX is much more difficult. Even when it looks like it will be easy (US-UK), there are tons of gotchas (I need to look up why they call apartments flats). -- Chas.

I have a package named Foo in which I want to define some
package-
level constants (such as $VAR=soemval). I want those constants
available to users of package Foo, so the following code would
work:
=== foo.pl ===
package foo;
use constant VAR = someval;
=== bar.pl ===
use foo;
print $foo::VAR;
It doesn't appear to be working; it compiles ok, but it prints
nothing. I thought it would print someval.
That looks interesting. How do people use that kind of constant
assignment. I can see uses for it, but would be interested to hear
what
others use this technique for.
Take a look at
perldoc constant
What the pragma creates is a prototyped subroutine with exactly zero
parameters,
so writing
use constant PI = 3.14159265359;
is equivalent to a subroutine
sub PI() {
3.14159265359;
}
However it has a few of advantages over just writing this directly:
- It is self-documenting, i.e. it is clear that a named constant is
being
defined.
- The Perl compiler has a chance to optimise out the subroutine
definition
and
call
- The implementation could change to something more optimal in the
future
without needing to alter any code that uses the pragma
I hope this helps,
Rob
Thanks :)

RE: Installing perl modules
Hi Andy, Andy Cravens wrote: Is there a way to have multiple users on a server using the perl at /usr/local/bin/perl and yet have their own personal perl modules that the other users can't see? ... During module install you can specify an alternate location to install the module using LIBS=/path/to/your/perlmods like this: perl Makefile.PL LIBS=/home/jdoe/perlmods but if I'm correct, I think these perl modules will be seen by everybody on the server. Can someone clarify this? I'm not sure if this is of any help since it was a while ago that I tried this. But I have done this before and if I recall, I did something like: perl Makefile.PL PREFIX=~/perl And then make;make test;make install. I don't recall using LIBS. And then, I had to do: use lib '...path in my home directory...'; in my programs. They were in my home directory, so no, no one could see them. Ray I think its even easier that that, from what I have seen. If you're a non priviledged user perl will decide a path to the modules based on that so its quite likely to be ~/perl/ blah blah. I wanted to install modules globally so I did it as root (or in a sudo shell). That's only from my observations though, but its easy enough to verify in your own environment.

RE: Send Mail with attachment
Hi All, I'm using perl module MIME::Lite to sent out email with attachments, may I know what Type should I define to attach any type of files, for instance .jpg, .xls, .doc, .pdf and etc without checking the attached file type. Is there any global variable to define instead of Type = 'application/zip', Type = 'image/gif', Type = application/ xls and etc? $msg-attach ( Type = 'what type should I define without checking the attached file type', Path = '$path', Filename = '$filename', Disposition = 'attachment' ) Please helps. I think that with MIME::Lite you can just set the type as BINARY or TEXT. I experimented with lots of types for zip files and xls/csv files and whilst is may break the RFC it does not seem to break how the item is attached eg I send xls files as text and it made no difference when the mail arrived in outlook with the attachement.

Spotted this, it might help you ?
Text::Diff
If all you need is confirmation that they are different perhaps a
checksum might serve you better?
Also comparing the files with diff will probably be quicker since it
has been written to do exactly that.

Generating Excel Charts from *nix
Hi all, I am looking to find a way to generate an excel sheet with charts on a *nix flavour (its MAC OSX Actually). I used Spreadsheet:::WriteExcel quite happily to gen a sheet and fill it with the data I want. However the chart facility has a slight drawback in that you need to build the chart and extend the series to allow for room to cover the largest number of data items you want to chart. The items I want to chart range from a series length of 1000 ranging to 7000. So I would need to allow 7000 for the reporting period that has lots of data. This means that the chart is either squashed up or could miss data items from the chart altogether. Unfortunately Spreadsheet::WriteExcel does not support named ranges - yet, and the chart series will not take a formula to redirect the reference to a range.

Subject: Perl Sockets oddity..
Hello,
I may be being a bit dim, but I wrote this:
#!/usr/bin/perl -w
use IO::Socket::INET;
print ISONAS Logger (perl) v1\n;
my $socket = IO::Socket::INET-new(
PeerAddr = 10.9.1.100,
PeerPort = 5321
) or die $!;
print Connected.\n;
$socket-print(login|);
while (true) {
$socket-recv($text,128);
print $text;
}
The data gets sent to the server, and data comes back, but does not
get displayed on the screen. However, if I change the while() to
while($text==$text), I get the following error:
Use of uninitialized value in numeric eq (==) at ilog.pl line 13.
Use of uninitialized value in numeric eq (==) at ilog.pl line 13.
Use of uninitialized value in print at ilog.pl line 14.
Argument 9/24/200812:25:43LOGON| isn't numeric in numeric eq
(==) at ilog.pl line 16.
Argument 9/24/200812:25:43LOGON ACCEPTED|| isn't numeric in
numeric eq (==) at ilog.pl line 16.
So, $text does contain the result, but for some reason it will not
print to the screen. I'm stuck!!!
[Stewart Anderson]
Is it that perl is interpolating $text and your argument has
symbols in it ? Quoting the var might help?

Sure... depends on the size of the log, though. Do that for a log that

RE: Fetching n number of records at a time in Perl DBI !

Cc: Amit Saxena
Subject: Fetching n number of records at a time in Perl DBI !
Hi all,
I am looking for a fetch function to fetch n number of records at
a
time
in Perl DBI !
fetchrow_hashref fetches one row at a time whereas
fetchall_hashref
fetches all the rows at a time.
The requirement is to get 100 records at a time (in array or hash)
before
printing it into the output file.
I don't want to use following style ;-
my $count=0;
while ($href1 = $sth-fetchrow_hashref())
{
my @arr1 = ();
$count = $count + 1;
%arr1 = %$href1;
if ($count == 100)
{
# print to the output file
print PTR %arr1;
}
}
Thanks Regards,
Amit Saxena
[Stewart Anderson]
Any particular reason you don't want to do that, it seems to me that
whichever way you do it you will need to loop through the returned
rows until they are all done.
There are the fetchall functions but I guess there is the risk of
returning a gazillion rows into 1 array there.

RE: Request for advice/suggestions....
your category subroutines, again a lot depends on
the
scope
of the data and subroutines involved ( chkclose(), for instance, and
anything
else you've edited out. But you could write something like this.
sub _process_category {
my ($hash, $text) = @_;
chkclose();
print HTML;
p align=center
b
font color=$config{colortablebody} face=Arial size=2
$text
/font
/b
/td
/tr
HTML
foreach my $key (sort keys %$hash) {
}
}
sub paper {
_process_category(\%paper, 'Paper Categories');
}
sub records {
_process_category(\%records, 'Records Categories');
}
But once again it would be best if these subroutines were exported
from
the
Categories module and the data itself was kept private. Only you know
what
is
possible here.
HTH,
[Stewart Anderson]
May be a bit late for this but, you could also use Config::Simple
to achieve this. I know its intended for config files but it would
lend itself quite well to doing what you want. The real benefit is
that you would not need to edit Perl at all to add new entries to
categories or entire categories, you could just edit your config file.
Couple of simple examples below. The Config::Simple docs describe
lots more functionality that you could use. Stick the commented
section into categories.cfg (uncommented of course)
#! /usr/bin/perl
use warnings;
use strict ;
use Data::Dumper;
use Config::Simple;
my $catcfg = new Config::Simple('categories.cfg');
print P01:\t . $catcfg-param('paper.p01') . \n;
Config::Simple-new('categories.cfg')-import_names();
print r01:\t . our $RECORDS_R01 . \n;
#[paper]
#p01 = PAPER ITEMS GENERAL
#p02 = Diaries and Journals
#p03 = Indentures
#p04 = Letters
#p05 = Certificates
#p10 = Other Paper Items
#
#
#[records]
#r01 = RECORDS GENERAL
#r02 = Birth and Death
#r03 = Marriage
#r04 = Wills

#r06 = Court and Probate

data
files.
Here is the problem I'm facing. I need to parse data from columns M
to P
and
rows 10 to 43000. Now I know that there is a PrintArea method that
can
print
an area of a worksheet specified in (start row, start col, end row,

col). However I'm having difficulty in specifying these parameters
correctly
for the PrintArea method. I'm also not sure what the output is going

look

does anyone in this forum have any pointers?
all advice will be appreciated.
tia,
anjan
I have only used the Simple version previously to parse and entire
row
but the method Cell ( ROW, COL ) In the docs for the module you
showed suggests you can get at the data directly.
Stu
Maybe I spoke to soon, that method seem to return the iobject, not
100% sure what that gives you without trying it.
But the sample script in the doc looks like a good place to start,
just set your row min/max and col min/max and you should be close to
getting something.
However, the sample program in the docs work as is. It should be
easy to adapt it for your needs. Try this as a start. The first bit is
pretty much out of the box and the last bit just shows you can extract
what row/column you want.
The data is at the end, load it into excel.
#! /usr/bin/perl
use warnings;
use strict ;
use Data::Dumper;
use Spreadsheet::ParseExcel;
my $excel =
Spreadsheet::ParseExcel::Workbook-Parse('c:\temp\filetest.xls');

once before it. If you use the connect_cached method instead of connect
then the
connection will be verified and used again if it is still valid.
HTH,

I have seen in other implementations.using a simple select
sysdate from dual (which is very fast since it does not query any
table) type of check and trapping the response to see if it is
connected. But, that will take more instructions than simply
re-connecting, don't know how much of a performance thing it will
be versus the select/check, Though if Rob suggests a re-connect,
he might already have been down that alley.

Hi All,
I facing one issue in Perl script. I am executing one command in Perl
script and taking the output of that command in one array. Now I want
to execute some more commands on each value of the array.
But the problem is that I am passing each value of the array as a
argument to that function but somehow it is not taking that value.
The output of the perl script is:
bash-3.00# perl backup.pl
/vob/test
Locking VOB 0
cleartool: Error: Unrecognized command: lock:0
Locking of VOB 0 failed
Now what I want is I need value /vob/test instead of 0.
Please find the attached perl script.
Please help/guide me.
Regards
Sayed.

Subject: Perl how to die without printing out a message?
Hi: I connect to a database within my script. If the script cannot connect, I
want it to send an email and terminate without printing any message on stdout.
I have the following code
$dbh =
DBI-connect(dbi:Pg:dbname=$dbname;host=$host;port=$port;,$username,
$password, {AutoCommit = 1})
or die notifyError($message, $subject);
When I run the script, it does call the notifyError function fine and I receive
the email. But it spits out the following message. Any way I can terminate
without putting any message on the screen?
-bash-3.00$ processRemedySubmit.pl
DBI connect('dbname=data;host=hostA;port=5435;','postgres',...) failed: could
not translate host name hostA to address: node name or service name not known
at ./scripts/processRemedySubmit.pl line 32
Died at ./scripts/processRemedySubmit.pl line 32.
Thanks

RE: 2 part question for DBI-1.604
Hi Tim, I totally understand the rebuild perl approach, you mentioned in that I know what you mean and how to go about it;but I'm fairly new to Perl too and that seems like a big undertaking for 1 module, 1, because I'm new to perl and building environments in general and 2. does it not run the risk of ending up with everything having to be built custom? Which I would think is something to avoid because then you have to rebuild everything custom on every environment in the same way etc etc. Hope that question makes sense.

Perl to ftp files remote to local
Hi, I'm sure there are a zillion ways of doing this, but rather than re-invent the wheel I thought I'd use my best skill - The ability to ask someone else and plaguerise :) So, I would like to poll a remote server (production app server) find files (log files) in a specific directory tree (recursive) and copy any over, say day old, to the local machine. I would like to do it in a secure way using ssh or some such mechanism. I can't put anything on the production machine, at best I could have it run a job to prepare a list of files for the remote to poll and trawl through. All pointers and suggestions appreciated :) Stu. Ps Why you ask? Well, there is no log file retention policy, logging is done locally and there is not enough disk to keep the log files for the period they are usually required - Yes I know - Please don't ask !!
