Message-Id: <8nt2de$sps$5@slb6.atl.mindspring.net>
Why is this printing only one or duplicate of one entries?
I am trying to find file pairs (same name, different extension) in a
directory. I'd like to collect the paired names in a hash. When I try
to print out the hash, I see that something is wrong. Here's my code,
followed by what I get:
---- code, watch for wrapping ----
#!perl -w
use File::Spec;
$dir = $ARGV[0];
$dir =~ s#\\#/#g;
print "Now we are opening ",
($dir = File::Spec->rel2abs ($dir)), "\n";
opendir (GRAF, "$dir") or die "Couldn't open $dir\n$!";
for (grep /\.gif$/i, (sort readdir GRAF)) {
$gif = $_;
# print ' '. $gif, "\n";
s#\.gif$#.png#i or warn "no .gif extension?!";
$PNGs->{$gif} = $_ if -e $_ ;
}
closedir (GRAF);
print "Listing of paired GIFs and PNGs: \n";
for (($d,$f) = each (%$PNGs)) {
print ' ', $d, ' ', $f, "\n";
}
----- /code ---------
----- output --------
Now we are opening E:\data\scripts
Listing of paired GIFs and PNGs:
JVOJAVA_bulletb2.gif JVOJAVA_bulletb2.png
JVOJAVA_bulletb2.gif JVOJAVA_bulletb2.png
---------------------
It's a whole script so readers can run it for themselves. but I'll point
out that if i uncomment the line
print ' '. $gif, "\n";
I'll see everything that i should see -- the list is loading up correctly.
TIA,

Do you mean:
operator_expression_1 : (operator_expression_2 operator_1
operator_expression_2)(?s)
| operator_expression_2
perhaps?
Either way, that's a strange rule in a C grammar.
Maybe you wanted:
operator_expression_1 :
leftop<operator_expression_2 operator_1 operator_expression_2>(?s)
> or whether that is doomed.
It would depend on the definitions of the operator_expression_2 and operator_1
rules.

Yes. Assuming the three alternatives are the names of suitable subrules.

Yes.

Exactly. The fewer levels of rules, the better.

RecDescent does not do this. It is hard to see how it could, since
it would first need to parse the text to find suitable points to
break it.
> (Would it speed performance?)
If *you* can find other ways to break the text, it will definitely
improve performance for large inputs.

Actually, I meant:
operator_expression_1 : (operator_expression_2 operator_1)(s?)
operator_expression_2
(This pattern goes through most of the grammar).
Redoing it as
operator_expression_1 : operator_expression_2
| (operator_expression_2 operator_1)(s?) operator_expression_2
Is one thing I tried to speed things up.
One example is :
additive_expression : (multiplicative_expression add_op )(s?)
multiplicative_expression
add_op : '+' | '-'
I also tried uniting this tree by making operator_1
stand for as many operators as possible (for my purposes
operator precedence does not matter). I may take this
further if it has a hope of solving the current problem.

Right now I'm just using smaller input files.

At least to some degree you could do
@chunks = split ';' , $input_text;
foreach (@chunks) {
$grammar->parse;
if (chunk wasn't fully consumed) {
unite with next chunk;
parse;
}
}
Or something along those lines.
But right now I've managed to break something more fundamental
because the script is not even reaching RETURN : ...
on my sample code (http://www.mit.edu/~ocschwar/sample.c),
so I need to see what I just broke.

Hmm.
Right now for some reason the rule for return statements,
/return/ <commit> {print 'return';}
(expression[context => 'return'])(?) ';'
breaks because of whitespace preceding the return statement.
Parse::RecDescent::skip is '\s*'
Is that not what it ought to be?

O'Reilly has a book called "Perl for System Administration" that could be
useful. (I haven't read it.) A quote from their web site:
"Perl for System Administration is aimed at all levels of administrators on
the Unix, Windows NT, or MacOS platforms. Assuming only a little
familiarity with Perl, it explores the pockets of administration where Perl
can be most useful, including filesystem management, user administration,
directory services, database administration, log files, and security and
network monitoring. Perl for System Administration is for anyone who needs
to use Perl for administrative tasks and needs to hit the ground running."
See http://www.oreilly.com/catalog/perlsysadm/.

compensation, monetary or otherwise, for mentioning a book published by
them. (But if they want to give me some money, that's ok.)]

I'll echo that. Jobs in the US for experienced Perl programmers with some
general skills also, willing to do moderate (and only moderate) travel,
making six figures, are going unfilled. Wish I could find people...
There may be ten times as many C++ jobs, many of which are also going
unfilled. Who cares--I don't enjoy C++.
The bottom line is that right now, geeks can pretty much write their own
tickets in most major US metropolitan areas. Perl and Java are both quite
saleable; better yet, know both. And nobody but nobody can predict how it
will be five years from now, other than that geeks will probably be making
good money in a variety of specialties. So this side of something that's
not going to sell at all (say, Turing tapecode), study what you find most
interesting. But don't get so thoroughly taken by any one language that you
lose the ability to move to another, if the whims of the business
marketplace drift in the next few years.

Not sure if I take your meaning correctly.
Did you get tripped up by my silly double-negative, despite the emphasis
provided by the asterix? I intended readers to understand that I meant: *each
one of us should (ideally) set our minds on becoming great life-philosophers*.
Not the sort of philosopher who merely spouts academic theoretical drivel but
practical, down-to-earth, grounded individuals who can speak out about right
and wrong (and the broad gray areas life holds, where the real challenge lies,
and where the naivitè of youth really shows its face). The modern American
attitude seems to be to leave it up to figures on electronic media to speak our
minds (or actually to make up our minds) for us. Which is a cop-out, an
abdication of personal responsibility.
Check out the great American philosopher/educator Dewey as an example of a man
who made plain clear thinking into a highly refined art form.
Also, BTW, this is a medium in which verbosity makes a message inaccessible to
the vast majority or potential readers; therefore the price exacted for the
severe brevity required by USENET is that generalizations get implied that were
not intended by the authors of msgs. The readers of this ng and programmers in
general are varied individuals of many degrees of capacity and maturity. Many
will be far more mature human beings than I myself. However if I am being told
I was obligated to make that elaborate disclaimer in my previous posting, I
contend that is simply argumentative-ness for its own sake.

Surely you know that a hash can hold only one datum per key. If there
will be several data per key, a different data structure is appropriate.

Just out of curiousity, why would you do that? Why does it matter?

Yes, you are (doing something wrong). Wrong shell syntax (not a Perl question).
Do `>help dir' or dir /?'in a Windows prompt, and I think you will find that
you must do:
dir <path> /options
IOW: `dir' on WinNT works differently from nearly any other shell command or
application anyone has ever used. Whaddaya expect, its Microsoft!

Good advice, but since he asked, he can learn about his OS' native shell too.
I don't know why doing it wrong sometimes works in the simple NT shell, but it
nearly always fails when programmatically applied in a script of any sort
(including a simple Windows batch file).

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.

To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
