Hi,
have a look at cpanratings.perl.org for a few popular ones.

Not in emacs. There is only one circumstance under which you
can run the debugger on a program that forks, and that is
when the debugger is running in an xterm (and IIRC the TERM
environment var must be set to 'xterm'). Then when the fork
happens another xterm will open with a debugger prompt for
debugging the child. You shouldn't find it any great
inconvenience to use xterm instead of emacs.
Under any other circumstance, running the debugger on a
program when it forks is disastrous. You get one terminal
talking to multiple processes and you will be lucky if
you can just figure out how to get out of them and clean
up.

Subject: Matching FP Numbers and Using Sprintf
Message-Id: <3F477235.583020D5@earthlink.net>
Maybe it's just me, but I don't find the documentation on
sprintf to be very enlightening. I've read it many times
and still can't figure it out, despite being a math kinda
guy.
I don't expect anybody here to explain it to me. It
would take way too much typing. I have the Camel
book and I'll figure it out today or tomorrow.
But one thing you could help me with is how best to
match a simple number with a decimal point (fp number?).
I want to match the 21.33 and 8.75 on the first line below.
I am using this right now:
/^\s{9}(\d{1,3})\s*[NS](\d+).\s+(\d+\.\d+)\'[WE](\d+).(\d+\.\d+)\'/i;
Does (\d+\.\d+) seem like a good way to you'all? Surely
there is a simpler way. I don't want a string, I want the
number (21.33).
Then I thought to do come calculations and make the
result a number like 99.1458330000 (10 digits after
the decimal point) I could use:
$l = $4+($5/60);
$m = sprintf %.10f, $l;
The error I get is
"Number found where operator expected at . . . line 28,
near "%.p" . . . "
I've tried a bunch of things, but can't fix the problem.

Message-Id: <3F473A0C.2060308@hotmail.com>
I just gained access to the Internet through my wireless phone. Most of
the sites I need data from contain no data because they're not setup for
wireless access. Quite frankly, everything I've seen so far is junk.
I'm thinking I need to learn how to "spider" a few important sites at an
indicated time, parse the data and print it to my own web server where I
can view it in a more "wireless friendly" mode.
Is this possible? Is it the right way to go? The sites I'm looking at
always print their data with the same HTML format so it would be easy to
strip out all the useless data and just keep what I need. I can do the
Perl coding for that but have no idea how to create the spider side of
it. How do I access data from another site using Perl in a CGI script?
That's the only coding I'm familiar with.

The LWP modules make it very easy to grab the content from a URL.
For simple stuff it can be as easy as:
use LWP::Simple;
my $content = get('http://www.perl.com/');
Then you just munge it to suit the format you want.
The various HTML parsing modules (such as HTML::Parser) make doing
that munging reasonably straight forward. Though sometimes a few
regexes will do the job - especially for non-critical personal use
stuff.

I would suggest googling for Nick Kew's mod_accessibility. Might not
be precisely what you want, but the approach would seem to be a good
framework for it.
OK, you can skip the google - I have the URL here

Even "personal use stuff" has a habit of adding features, bit by bit,
until it turns into an unmanageable mess. (And I say that from
well-earned personal experience.) I'd recommend starting with a sound
foundation, upon which, later enhancements could be added without
digging oneself into a deeper and deeper pit.
And, as I thought the example of Nick Kew's mod_accessibility could
illustrate (as the basis of an idea that could be implemented in other
languages, natch) - by doing the basic thing right you can have a
structure that's sufficiently versatile to do a range of jobs, which -
with the rapid developments of mobile/wireless kit - would seem
valuable even for a "non-critical personal use" project. As long as
the components (CPAN modules etc.) are there, all you should need to
code would be some Perl glue to hang them together.
IMHO, anyway.

That is useful. Thanks for the pointer.
Pack and Unpack is something that is often overlooked by me
in favor of regex's. Not sure that will change, but these
functions appear very good for fixed width formats.

I just have to ask, what is that '&' in [A-Z&] doing?
Is it just matching anything that starts with '&' in addition
to A-Z? I suspect not - I suspect it's doing something else.

you should check out expect (http://expect.nist.gov).
i wrote something similar years ago using expect, a point-and-click GUI
(like your simple text input box), and xterm to allow complex
command strings to be input at the click of a button, while still
providing the user the capability to interact directly through the
xterm. the expect example 'kibitz' script got me started in the right
direction.
essentially, you need to allow the xterm to be able to take input from
both direct input (user typing) as well as your input box.
so, write an expect process that both spawns (expect terminology) a shell
(for user typing) and opens a "file" (i used named pipes, iirc) for
reading input from your text input box. write your expect script to read
from both input sources and send the output to the xterm window.
my app was single GUI <-> single xterm, so my GUI didn't have to do
anything more than write its generated text strings to the named pipe.
you want your text input box to send to multiple xterm windows, so you'll
need a way to provide that 1:n fan-out. if you're using named
pipes, for instance, you could have your text box send its output to all
the named pipes; the expect process at the other end of each of the named
pipes will consume the input.
i'm sure there's probably a perl way to do this - but the expect FAQ
addresses this topic better than i can.

Riddle me this: Is it such a crime to ask a question pertaining to vi or
Emaces or apache that would allow you to work with Perl directly? Ok, you
would not ask general vi or Emaces or apache questions in this group, but
there should be no hard in a question that a someone having used Perl might
know, such as, for sake of example, "how do setup perl syntax
checking/highlighting in Emaces?" Editors that you two have named are some
of the most popular editors for UNIX users who write Perl, just like Apache
is very popular for Perl coders who wish to expand their application of Perl
to a web browser.
The point is, such topics have quite commonly been dismissed as off-topic,
when they indeed relate to Perl, more to something more akin to what should
be maybe. YES, it's not language specific, but there are also many things
that people in a vi, or Emaces or apache may not know about Perl (and setup
stuff and the likes) that a seasoned Perl user likely would.
I think it's 100% impossible to have dedicated groups for *every*
possibility and cross subject. If attempted there would most like be at
least an order of magnitude more news groups on public/ISP Usenet servers
then there already are.
Are we just suppose to just out-law anything and everything simply because
it doesn't meet a tight topic criteria?

there is even a autoposted perl in emacs post in this group.
but configuration of emacs is offtopic. configuration of apache is
offtopic. neither involve the perl language or program which is the
topic of this group.

you still have to differentiate whether it is perl specific or
apache/editor/whatever specific. in fact knowing the difference will
lead to a faster solution to the problem for the poster.
so telling someone that it is not a perl problem is actually helping
them. the poster doesn't know enough to tell that for themself.

sure 100% is impossible. but 95% is doable and reasonable.

to some value of epsilon it is tight enough. and that is true for most

I'm going to have to suggest some attention to your reading
comprehension. "Many of the serious users" does not even attempt to
speak for "every" person in the group, but as a long-time contributor
here (and editor of part of faq9 where these issues are explored) I do
think I have the approximate temperature of the group, and I can
confidently inform you that there are plenty of serious Perl
programmers who do not write CGI scripts.

If I had said what you appear to believe I had said, then I would

Well, that is an accident of history. The rmgroup for comp.lang.perl
was properly issued, but for whatever reason it wasn't actioned
everywhere (I think detailed discussion of that would be for a
history-of-usenet group rather than here, but as Jon Bell is on the
thread maybe we'll get an informative comment?).
Conversely, comp.infosystems.www.authoring.stylesheets was properly
created, but for many years a significant proportion of servers failed
to honour its existence, which was annoying for the participants.
What's odd to me is that big-8 chkgroups messages are sent at
intervals, which are supposed to facilitate synchronisation of the
newsgroup names, but it seems that some servers don't honour those
either.

Usenet is a community which, like all communities, has some of its own
special rules, that aren't necessarily self-evident. That's why there
are new-user FAQs. It isn't done that way in order to deliberately
expose newcomers: rather, it has grown up over time for a variety of
different reasons, for which no one individual is to blame. In the
words of the prophet: "cope with it".

Sure, that's why, when we think they're in the wrong place, we try to
direct them to what we think would be a better place.

If you have a question about how to use mod_perl then I think nobody will
yell at you, although maybe CLP.modules might even be a better place to ask.

Sure. As is Linux and FreeBSD and Windows9x and Windows2k and Mac and
Solaris and .... for non-web oriented.
Does that make any question about how to configure Linux, FreeBSD,
Windows9x, Windows2k, Mac, Solaris, .... an appropriate topic for this
group?
If the answer would be "Well, you do it exactly the same way as you would do
it for Fortran or C or Basic or Lisp or ...." then obviously it has nothing
to do with Perl.

Sure. Just as Perl has a large followship among Unix adminstrators or
managers of large programming projects even on Windows. Does that make any
Unix administration question on topic here? Or any question about manage a
multi-million line programming project?

As is Notepad or vi or emacs or even DOS. Yes, DOS: if you are using Windows
then you still need some place to run your Perl script. Does that make any
DOS question on topic here?
If the question is related to Perl, then probably yes. Heck, there is even
an FAQ entry about that DOS quotes are different from Unix quotes or about
the infamous differences in line end characters.
But let's say "How do I set my path in DOS so that I can call Perl"? Well,
you do it exactly the same way you would add any other directory to your
path.
"How do open a new window when a user clicks a button?" Well, you do it
exactly the same way as you would do it in C or Haskell or Cobol (assuming
you are asking about a CGI script; most often people don't even mention that
little, minor detail and you wonder if they are talking about Perl::Tk or
Win32::API or what).

It's as simple as the fact that the moderator of news.announce.newgroups
can't hold a gun to every news server administrator's head and tell
him/her, "remove that group or I pull the trigger." :-)
Very few servers carry out all control messages (especially rmgroups)
automatically because it's too easy to forge them. It's possible to set
up a server to use PGP to verify the sender of PGP-signed control
messages, but many server admins don't go to that trouble.
Newgroup control messages are affected by the same considerations, but at
least if someone using a certain server doesn't see a new group show up
that he's been waiting for, he can ask the server admin to add it, and
usually it will be done. I doubt that many people would take the trouble
to ask their admins to remove a "bogus" group that they know about.

A perfect example. This sort of thing is probably the biggest factor that
led the new team of n.a.n moderators last year to impose a moratorium on
converting unmoderated groups to moderated ones. It's confusing when some
servers carry a group as moderated and others carry it as unmoderated.

As with other control messages, in order to be sure a checkgroups is
valid, you need to use PGP.
