Efficiently going through results
Hello,
I have a problem, which I have put into an analogy.
Suppose a parent has 11 children. These children like chocolate. If 9 or
more of the 11 children from the same parent like a particular chocolate,
the parent will like the chocolate. I want to find out what types of
chocolate each parent likes.
I have a file listing each child's preference of chocolate (which can be
= 1). There are +45,000 parents, each parent has 11 children and there
are +100,000 different types of chocolate.
I guess I could parse the file and store the results in something like this
$listOfParent{$parentOne}{$childOne} = @chocolate;
...
$listOfParent{$parentOne}{$childN} = @chocolate;
...
$listOfParent{$parentN}{$childN} = @chocolate;
Then
my %result = ();
foreach my $parent (keys %listOfParent){
my $chocolate = '';
foreach my $child (keys %{$listOfParent}{$parent}){
foreach ($listOfParent{$parent}{$child}){
$chocolate = $_;
if (exists $result{$parent}{$chocolate}){
$result{$parent}{$chocolate}++;
} else {
$result{$parent}{$chocolate} = '1';
}
}
}
}
Then go through %result and print out the =9. Is there a better way of
doing this?
Cheers,
Dave

Mac::Glue with Adobe Illustrator
HI - Has anyone on this list used Mac::Glue, specifically to script Adobe Illustrator? I have been trying and trying to get it to work, alas, no joy. Simple things (start Illustrator, activate, quit, etc) work, but as soon as I start using parameters I run into a brick wall. This script to open an existing .ai file: #!/usr/bin/perl use strict; use warnings FATAL = all; use Mac::Glue qw( :all ); my $ill = Mac::Glue::-new( Adobe Illustrator ) or die cannot get Illustrator: $^E\n; my $file = video-test.ai; $ill-open( $file, ERRORS = 1 ); yields: rocky:test beau$ perl hello.pl Adobe Illustrator-open(DOBJ, video-test) event failed: errAECoercionFail (-1700) bad parameter data or unable to coerce the data supplied I installed Mac::Glue 1.30 against perl 5.10 using macports, I followed the instructions to make the Illustrator glue and made the scripting addition glues.

AW: Efficiently going through results
Dave Tang d.t...@imb.uq.edu.au asked:
my %result = ();
foreach my $parent (keys %listOfParent){
my $chocolate = '';
foreach my $child (keys %{$listOfParent}{$parent}){
foreach ($listOfParent{$parent}{$child}){
$chocolate = $_;
Why not foreach my $chocolate ($listOfParent{$parent}{$child}){?
if (exists $result{$parent}{$chocolate}){
$result{$parent}{$chocolate}++;
} else {
$result{$parent}{$chocolate} = '1';
}
You can just say $result{$parent}{$chocolate}++; - non-existing keys will be
created automagically.
If you don't need to know which child likes which chocolate later on, I would
not bother with tracking that data. Just add the preference to the parents data
while you're reading it from file.
HTH,
Thomas

I guess I could parse the file and store the results in something like this

More precisely,
$listOfParent{$parentOne}{$childOne} = [ @chocolate ];
since hash elements must be scalars.
...
$listOfParent{$parentOne}{$childN} = @chocolate;
...
$listOfParent{$parentN}{$childN} = @chocolate;
Then
my %result = ();
foreach my $parent (keys %listOfParent){
foreach my $parent (keys %$listOfParent) {
(note: $listOfParent and %listOfParent are two different variables)
my $chocolate = '';
foreach my $child (keys %{$listOfParent}{$parent}){
foreach my $child ( keys %{$listOfParent-{$parent}} ) {
(note: $listOfParent{$parent} is an element of %listOfParent, not an element
of the hash referenced by $listOfParent)
foreach ($listOfParent{$parent}{$child}){
foreach ( $listOfParent-{$parent}-{$child} ) {
$chocolate = $_;
if (exists $result{$parent}{$chocolate}){
$result{$parent}{$chocolate}++;
} else {
$result{$parent}{$chocolate} = '1';
}
You can replace the above 5 lines with just this:
$result{$parent}-{$chocolate}++;
as Perl will treat an undef value as zero in an increment operation.
}
}
}
Then go through %result and print out the =9. Is there a better way of
doing this?
If you don't care about the names of the parents and children, you could use
an array of arrays instead of a hash-of-hashes to store the preference data.
Arrays will use a little less memory storage than hashes, and access will be
a little faster. If, however, you already have your hashes created for other
purposes, then converting to arrays will probably not help.
A little whitespace sprinkled into your source code makes it more readable,
which is always a good thing when you are looking for help.

Hi Chas,
I was hoping that I could find a module that allows me to do something like:
use The::Module;
my $client = The::Module-new(PeerAddr = 'localhost:9000');
$client-send('those 3 parts of the message I want to send');
while ($client-eof) {
my $result = $client-receive();
}
(The code might not be a good one, but I think you understand what I want.)
Or can you give or tell me where I can find an example about how to create
this simple client using IO::Socket::INET?
IO::Socket::INET doesn't give too many details about the methods it
supports, and I need to also study IO::Socket, and Socket and finally many
other built in perl functions or perlipc. I will study them, but I told I
was searching for a higher level module because I am sure I will need just a
few methods from all those offered by IO::Socket::INET.
Thanks.
