I _really_ want to thank you for mentioning this. I've been dreaming
of such a thing for years, and had no idea someone else not only had
the same itch, but had successfully scratched it so to speak.
Thanks again!

Don't thank me. Thank Scott Pakin, who wrote PerlTeX.

well, I was looking through the code, and I thought I could get it to print
some information on how to use it, but then I realized it's probably just
the comments and some docs in there as commnets, I'm still not sure about
this, I'll have to look again, it's near the bottom.

That's more or less what it is. The docs you read with the 'perldoc' tool
(or as man pages, or HTML, or ...) aren't stored separately. They're
embedded in the module itself, in a format called POD - Plain Ol'
Documentation.
See 'perldoc perldoc' for more about the perldoc tool.
See 'perldoc perlpod' for more about the POD format.

two thoughts (i have used P:RD but i am no expert in it). first, you can
use regexes instead of strings and then use anchors/assertions of some
sort:
home_run: /\bH\b/ | /\bHR\b/
also i was under the impression that basic P:RD will split input on
white space so the home_run production should only match H when the
token is H.
all this is conjecture and hopefully the damian will see this and jump
in to correct me. will someone please turn on the damian signal lamp? :)

Right. The problem is this data is *not* split into tokens by white
space. For instance `H8' is the code for an inside the park home run
fielded by the center fielder. Sorry I didn't make that clear.
Someone wrote an email with the suggestion:
home_run: /H(?![A-Z])/ | 'HR'
That does the trick, I think.
I'm not sure Parse::RecDescent is the right tool for the job, but it
sure is fun to play around with. :)
Thanks,
Jon

Hello all,
Yes I'm aware this is the wrong newsgroup (so please point me to the
right one please) I looked in alt how to but only porn there.
So please don't flame
My question is this.
I use whisper (a password generator) for accounts.
Meanwhile i have 1500 accounts so i want to put things in a database
or report to analyse.
Problem is that Whisper doesn't have an export function to ascii text.
I mailed the author of the program and he says it's programmed in
delphi and he hasn't the time to programm this.
I'm not a programmer but i remember from my dos days that you can
print-to-file somehow. I like to think i have a text-file and then i
can arrange things. (I'm trying to learn perl so i have a good
playfield to experiment)
I use Windows 2000 and i can't think of anything to solve my problem.

I won't flame, just point out alt.os.windows2000 or the large
and often informative newservers supplied by microsoft snews.microsoft.com
which covers a whole multitude of sins :)

If the output is to the dos screen the adding a > c:\yourfile.txt will
save the output to the ASCII file c:\yourfile.txt if you are generating
lots of different executions of the program you will want to replace >
with >> to append.
whisper >> c:\passwordLog.txt
using a relative path rather than the absolute path above will create the
file relative to the working directory.

Join Nader supporters in DC, April 24-25,
as they rally for justice and equal rights
Washington, DC:
Saturday, April 24th, IMF/World Bank Protest - meet at 11am, 15th & H St, NW.
Sunday, April 25th, March for Women's Lives - meet at 9:30am, Smithsonian Metro Stop.
If you arrive late, ask a volunteer to point you towards the Ralph Nader group.
See you there!
Nader: Oil the Source of Two of Earth’s Major Problems:
Wars for Oil and Climate Change
Protect the Environment and the People of Our Planet by Ending Our Addiction to Oil
Washington, DC: On Earth Day 2004, Independent presidential candidate
Ralph Nader highlighted as two priorities: ending the Iraqi occupation
and facing up to the immediate crisis of global climate change. "Future
geopolitical crises involving oil resources and environmental problems
will be diminished by finding alternatives to fossil fuels," said Nader.
Nader linked the two issues on Earth Day because he sees them as
symptomatic of the corporate oil-based, planet destructive behavior of
the Bush Administration. Nader has called for the United States to
withdraw from Iraq - including military, private military contractors,
oil industry and other corporations. Nader noted: "The war in Iraq is
unleashing widening cycles of violence. The potential for escalation of
violence increases every day the US military remains in Iraq. The way to
reverse the spiral of violence is for the United States to go back home.
The US presence serves as a magnet for the insurrection, kidnapping,
terrorism and destruction." Nader released a three-step strategy for
withdrawal earlier this week. See www.votenader.org for details.

is a simple classic stew that makes natural gravy,
thus it does not have to be thickened.
Brown the meat quickly in very hot oil, remove and set aside.
Brown the onions, celery, pepper and garlic.
De-glaze with wine, return meat to the pan and season well.
Stew on low fire adding small amounts of water and
seasoning as necessary.
After at least half an hour, add the carrots and potatoes,

Boil the prepared delicacy until the meat starts to come off the bones.
Remove, de-bone and cube; continue to reduce the broth.
Brown the onions, peppers and celery.
Add the meat then season, continue browning.
De-glaze with sherry, add the reduced broth.
Finally, put in the root vegetables and simmer for 15 minutes.
Allow to cool slightly.
Place the pie pan in 375 degree oven for a few minutes so bottom crust is not soggy,

I'll think about that - though there's only a very small penalty with
the current '*=' overload subroutine. On my 1GHz box 50,000 calls to the
overload subroutine adds about 0.06 seconds (in comparison to 50,000
calls to the alternative GMP library function), so I don't think there's
much room for more gain there.
(The overload sub currently contains a 'SvREFCNT_inc()' inside every
'if{}' block. All that's really needed is just the one 'SvREFCNT_inc()'
before the first 'if{}' block. I'll change that in the interests of tidy
coding :-)
Thanks again Anno.
