Well, I wouldn't call it "garbage". I can imagine useful uses for
those. Actually the behaviour with IMs is good. Pidgin, for example,
doesn't at least under Windows, and it only gives an acoustic signal:
so sometimes I maximize it to check who logged in, and of course I
would prefer the notification instead. Said this, the thingie is
*probably* doable in Tk and in other toolkits: it's enough to fork
another process which will consist of a single window, emulating all
the motion by itself, and with special decoration... it is not true
that all Tk apps are forced to have the classical Tk look & feel:
indeed they can be quite different. Of course I've seen *gurus* do
this kinda things, and I'm not, let alone a beginner, so I wouldn't
know where to start, but yes: I think it's *doable*, just not easily.

History, and backwards compatibility. Win32::GUI up to V1.04 exports
lots of constants by default (300+ of them), and if you don't want
them you need to apply an empty import list. V1.05 still exports
these constants by default, for backwards compatibility, but warns
with an empty export list - so right now now you need an empty export
list if you don't want the constants, and you don't want the warning.
A future version (probably 1.06, but not decided yet) will stop
exporting the default constants (and will issue a warning without an
empty import list); A further release will remove the warning,
allowing a simple
use Win32::GUI;
to not pollute the caller's namespace. It takes time to change the
past.

Rob.

What version of Win32::GUI, and what version of perl? I fixed the
missing POD documents (I think) with Win32::GUI 1.05. Sadly with
ActivePerl 5.8.8, the way PPM deals with generating HTML from the POD
changed, and despite great efforts to distribute correctly formatted
and linked HTML pages, PPM insists on re-building them , and does so
wrong (if you look at the HTML docs, you'll find all the links are
absolute, and o the directory where the PPM got unpacked. It's on my
list of things to look into for the ext release. In the meantime all
the docs are available on line at http://perl-win32-gui.sourceforge.net/docs/
(although I won't pretend that they are complete or 100% accurate)

This is not good idea ;-) DOS name of this directory will be
"C:\Progra~1\Perl" and sometime you could have problems. Above this in few
files in C:\Perl directory is stored this path, e.g. C:\Perl\lib\Config.pm

Thanks for the generous response. I actually had perldoc perldata already
opened in a dos window, leftover from last night. The first sentence is:
Perl has three built-in data types: scalars, arrays of scalars, and
associative arrays of scalars, known as "hashes". But I read right over it,
because I didn't know what I was looking for. BTW for newcomers like me, it
helps to read these things in a better environment than a crappy dos window.
You can redirect with perldoc perldata >text7.txt, and then find the doc to
open with your program of choice.
So the arrays don't associate as in a *(b*c)=(a*b)*c, but the values and
keys associate, as in, if you have one, you can get the other. I find the
semantics of perl quite challenging.
Cheers, merl

So far, so good.

Not so good.
If you have the key you can get the value, but not the other
way around (because there may be multiple keys with the same value).

The semantics of a hash data structure are what you find challenging.
Hashes were around long before Perl, try googling "hash data structure".

Hi,
In the context of cooperating forked processes (not threads as you
mentioned), I used this module:
IPC::Semaphore
However, there might be a better way with threads - best hang around in case
someone else can add anything. I never do threaded programming.
Cheers

You can declare a shared variable (see threads::shared) to serve as a
sempahore, and lock that.
{
lock $sema;
print "hello";
} # automatically released on scope exit
Or maybe use Thread::Semaphore, which I have never used.

Subject: Life + Perl = Golly
Message-Id: <andrew-1307071319020001@192.168.1.2>
Golly is an open source, cross-platform Life app which uses
Gosper's hashlife algorithm to allow the exploration of patterns
at unprecedented scales and speeds. More details are available
at Golly's web site:
http://golly.sourceforge.net/
Golly has been using Python as its scripting language, but the
following 1.3 beta versions now support Perl as well:
ftp://ftp.trevorrow.com/beta/golly-1.3-win.zip (Windows 2K+)
ftp://ftp.trevorrow.com/beta/golly-1.3-gtk.tar.gz (Linux i386)
ftp://ftp.trevorrow.com/beta/golly-1.3-mac.zip (Mac OS 10.4.x)
ftp://ftp.trevorrow.com/beta/golly-1.3-mac1039.zip (Mac OS 10.3.9)
See Help > Perl Scripting for all the details.
A number of example .pl scripts are included in Scripts/Perl/.
I don't have a lot of experience with Perl so it would be nice
if a Perl expert could run their eye over my code and check
for any bloopers or inefficiencies. Other Perl scripts would
be most welcome.
Golly uses an embedded Perl interpreter to run .pl scripts
and should work happily with any Perl 5.8.x installation.
Please let me know if you have any problems.

Thanks for that, Andrew. I just downloaded it. Now,
without looking to see if this is there yet, one
thing I wanted in the previous release was more
complex selection mechanisms, so that I could
select, say, a box and then select out the middle,
or otherwise decorate the Golly universe with a lot
of disconnected selected areas, before turning on
"random fill" and going away for the many minutes
such a fill typically would require. A look at the
GIMP selection capabilities will give you an idea
what a rich set of such tools could look like.
I didn't understand from your writeup: if Golly has
a "built in" Perl interpreter, why is some external
Perl environment needed?
Quantum valeat.
xanthian.
By the way, Golly has some utility as a source of
input for abstract art, perhaps not its design use.

Good of you to let us know. Indeed I had I known about that, and I
probably would have, if I had read the whole documentation as I
recommended to the OP, I would have use it instead of manually parsing
the headers. Only I'm curious as to know whether the date, if present,
is always the third field... I also have another question for you: I
wouldnt' use a MESSAGE-SPEC comprising *all* the available articles
anyway, but from the communication with the server POV, is it better
to call the xover method for each of them or for a bunch at a time,
say 10 or 100?

The offending line was:
my $nntp = Net::NNTP->new($SERVER, ( Debug => 1) );
, with curly braces around the debug expression. Would it, for example, be
a syntax error if I wrote:
my $nntp = Net::NNTP->new($SERVER, ( Debug <= 1) );
, with the arrow operator backwards?

If it is installed on your system (and it should be because it comes
with recent perls), enter
perldoc Benchmark
See 'perldoc perldoc' for details and options.

You can tell if it is a syntax error because the program will
fail to compile or run.
If it runs, then it does not contain any syntax errors.

That is *syntactically* correct [1]. *Semantically* wrong.
To help understand the difference, consider a bit of
natural language instead:
Pigs can fly.
That is syntactically correct. It has an object where an object
goes, a verb where a verb goes, etc...
It is semantically incorrect however. [2]
[1] because <= means "less than or equal".
[2] except perhaps for a cruel use of a trebuchet. [3]
[3] Oh, I was thinking of cows, not pigs.

Er, why don't you just answer his question (what version)? He's asking
for actual information, which will help us understand what you are
(trying) to to say.
If you continue to just make vague and unsupported (and rather hostile)
assertions, without examples, version numbers, or other concrete
information, do you expect anybody will continue listening to you?

Some people can't let sleeping dogs lie I guess.
I can't remember the specific version after all these years. It may
have been 18 or 19 point something. As for "concrete information" this
thread is littered with fairly specific anecdotes. I know, I know;
anecdotes aren't really proof of anything. Got any better suggestions?
HCI stuff is a bit slippery to try to hang a rigorous theory and
quantitative facts upon. For most people, a crappy interface isn't
something they can precisely define, but they know it when they see it
(or at least try to use it).
