RE: Calling a module within another module
Please ignore my previous problem. I was introduced to a function called Exporter. Not sure how general it is, but for those who want to know, this is the syntax use Exporter; @ISA= 'Exporter'; @EXPORT = qw (&showdays &showmonths &showyears ); sub showdays etc..

Hello,
Can I do something like this:
my @array;
while () {
chomp;
push (@array, $_)
if m/AAA/i;
print "Reading logs...\r";
}
but have it search for more than one string (AAA being that one string)?
I'd like to search for AAA, BBB, and CCC and have all results be put into

Thanks everyone,

Calling a module within another module
Hi, I have a bit of a problem, that I am SURE there must a simple solution for, but I can't work it out. I have a very simple module which just contains some subroutines to return a drop down list of days of the month, with the current day selected. This is going to be used in a few spots, so I wanted to put it in a nice central area. There is another module, that takes the results of subroutines (always a string) and replaces variables on a HTML template with them. It calls it by requiring the replace variable and the subroutine: eg MID => [\&returnme, $merchant_id] where MID is the variable being replaced, returnme is the subvariable, and $merchant_id is a variable the function needs. This works fine whenever the sub is within my perl script, but for all the ones in my third party module, it falls over with a "no a code reference" It is probably how I am calling it, but I can't work out how! I have StartDay => [\DropDates::showdays, "startday", "19"] where DropDates is the name of the module, and showdays is the sub I want. I've also tried DropDates::&showdays, but that also doesn't work. Any ideas? I'm using strict in all modules, and I can't change the HTML template module, as it is not my property. Thanks!

assigning complex data into a hash (of hashes?)
Hi,
I have a data file in which each line is an instance of an event (e.g. a
sale). The file contains info about where the event happened (the city,
state, country), the type of event (catalogue, telephone, in-store) and some
other classification data (cash, credit card, indentured labor, firstborn
child).
Data fields are:
timestamp
product_name
geo1 (e.g San Francisco)
geo2(e.g. California)
geo3 (e.g. usa)
geo4(West)
type1 (store)
type 2 (cash, etc.)
So, if there were 5 sales in San Francisco, then there will be 5 lines in
the text file.
I want to slurp in the whole file and put it in a hash structure of some
sort so I can count totals within each field.
e.g, print out a total of sales by State or by City or by region. I might
not know how many cities are in the field or how many state. The key will
always be the product_name field.
Do I need to make an array for each field, like this:
while (<$line>) {
($time, $product, etc.) = split(/,/,$line, 8);
push @{ $hash1{$product} }, $geo1;
push@{ $hash1{$product} }, $geo2;
etc.
and then count the number of entries by category later on, when I'm looping
through the appropriate array? (That is, for each "city" in geo1, count
it--5 "San Francisco's" means 5 sales in SF.
I suspect that there's a better structure, which allows me to total the
counts for each field as I load it. And that I can use anonymous arrays to
load in the whole thing once.
I'd very much appreciate any advice.
Best,
Sean

When you use an undefined value as a reference, Perl creates that
reference for you automatically. THAT is autovivification. Thus, when
you do:
my $x;
$x->{foo} = 10;
$x->{bar}[5] = 20;
You've autovivified $x as a hash reference from the second line, and
autovivified $x->{bar} as an array reference on the third line.
When you do:
open my($foo), $path;
Perl is expecting a typeglob. If you give it an undefined value, it
autovivifies the typeglob reference, so *$foo is the filehandle. However,
references to filehandles are accepted wherever a filehandle is, so you
can just use $foo and get away with it.

Bah! You're right of course. The actual script is
print join ":", grep !$seen{$_}++, split ":", $ENV{shift || PATH}
and I don't use strict or warnings.
There's probably a lesson or three in there somewhere.

The perl you're using with bugzilla is different from the perl you're using to install modules. I don't recall, does bugzilla use mod_perl, or simply CGI scripts? If the former (mod_perl) then you need to recompile mod_perl to use the more recent libperl.so; if the latter (CGI script) your shebang lines are likely to blame. You can either fix the shebang lines, or fix the perl they're pointing to to point to the correct perl.

Re: POE
Hello, I experienced similar error messages and found that the solution involved the following steps: 1. visit www.cpan.org to download the missing module. 2. unarchive the module according to the prescribed instructions and 3. made sure that the module was in the perl directory. So either you do not have the Call.pm module yet or if you already have, it is not in the correct path. Usually the author of perl modules specify which other modules that they incorporate.

This is the error: assignment of an array to a scalar returns the number
of elements. You want want one of the following:
my $id = shift;
my ($id) = @_;
my $id = $_[0];
> if($id =~ m/^.+_.+$/i)
You're doing too much work here. Just use the regex
if ($id =~ /_/)
instead of working on the entire string. Also, you can write:
return $id !~ /_/;
which will return true or false. Since you want the OPPOSITE value, I've
used !~ instead of =~ here.
Finally, you don't really need a regex in this case:
return index($id, '_') == -1; # -1 means not found

I'm not sure why you need a separate subroutine here, since the regular
expression returns true or false already and can be used directly in the
if statement. At any rate, if you are just checking to see if there is an
underscore in the string, then just test for that:
$id = 'xty_1233';
if($id =~ /_/) { print "Is Faculty/Staff!\n" }
else { print "Is Student!\n" }
You can make this even more succint by using the trinary operator (?:),
but I'll leave tht as an exercise for the reader.

RegExp Problem...
Hi folks,
I'm stumped...I wrote a test script and this pattern matches just fine, but
when I try to use it in another script it does match as it should.
Basically, if the pattern detects an _ underscore in the string it should
return undef; if it doesn't match it returns true. Here's some code:
if(isFacStaff('xty_1233'))
{
print "Is Faculty/Staff!\n";
}
else
{
print "Is Student!\n";
}
sub isFacStaff
{
my $id = @_;
#this will match student-style ID's
#it is rather easier to match against student IDs than staf IDs
if($id =~ m/^.+_.+$/i)
{
return;
}
else
{
return 1;
}
}
Thanks in advance for any help!

Re: regarding win32 functions
you can discriminate by OS if that helps you:
$^O will hold the name of the operating system you're running on
(alltho i think it'll probably be in %ENV somewhere too)
so something like this might work:
BEGIN: { use Win32 if $^O eq 'MSWIN32' } #or whatever it's called again
depending on the context of which you are writing this, many options are
possible.
you could have 2 different files holding os-specific methods to use
depending on the OS
or you could eval the statements, trapping errors as they might come up
or just write 2 completely different programs.
all depends on what you need

regarding win32 functions
Hi, i have used use win32::process() statement This statement is used only for NT ie using if statement. In NT, this is used to kill a process. But when the same code is taken to UNIX, it is giving compilation error. Ie, its searching for Wind32 libraries in UNIX which is not existing. How to resolve this problem?? Is there a facility in perl to have preprocessor statement.
