Subject: a subroutine as a string?
Message-Id: <9j9r1g0279t@drn.newsguy.com>
Hello,
I'm trying to use a small subroutine as a string variable and then pass that to
an eval. Eventually this is to be used with mysql and a more complicated scheme,
but I have a small test program that I can't get to work. Does anyone know why I
get an error running this:
#!/usr/local/bin/perl
$hook="sub {print 'hello world'; }";
print "hook is '$hook'\n";
eval { &{$hook}(); };
print "$@\n";
The error is:
Undefined subroutine &sub {print 'hello world::; } called at ./testhook.pl line
5.
This will be working with a commercial software module, and the eval is from
their software, so I can't really change it without affecting other things. I
have to figure out how to make the string correct.
Any help would be greatly appreciated.
Griff Hamlin, III

Depending on which parts of the code you have access to, you could
try one of these:
# their code
$hook = q[ sub { print "hello world\n" } ];
# your code
$func = eval $hook;
$func->();
# your code
$hook = sub { print "hello world\n" };
# their code
eval { &{$hook}(); };

The 0/1 Knapsack problem is similar, but sycorax is describing
SUBSET-SUM, which is, as you noted, NP-complete.

Proof of this problem being without solution is quite easy
and this proof is just as easily stated in one logical step
via a question,
"What are the contents of the originating author's hash?"
Both of the originating author's articles are so absolutely
incoherent, there are myriad interpretations of what is being
asked. Nobody can provide solution code save for the originating
author. Randal is correct per his personal perception of what
is being asked.
Your thinking is as flawed as is the originating author's articles.

You don't even understand what we are talking about, do you? What
relevance does the OP's hash have to the question whether the knapsack
problem is solvable in polynomial time?

Sounds like homework, but it's fun and I haven't done recursion in perl
before, so here's my proposed solution.
#!/usr/bin/perl -w
use strict;
use diagnostics;
my %hash = ( apple => 1,
banana => 2,
pear => 4,
bear => 8,
beer => 16,
deer => 32,
dear => 64,
tear => 128,
) ;
sub findsum {
my $need = shift or return [];
my $key = shift or return undef ;
my $x = findsum($need,@_);
return $x if $x;
$x = findsum($need-$hash{$key} , @_ );
return [@$x , $key] if $x;
return undef;
};
my $ref = findsum( $ARGV[0] , keys %hash);
print $ref ? "solution:@$ref:" : "no solution" , "\n";
__END__
knapsack.pl 7
solution:apple banana pear:
Seems to work.
I'd like to get of rid of $x entirely, but can't figure out how to do it
efficiently. (without just changing the name to something else)
return findsum($need,@_) || (findsum($need-$hash{$key},@_) ?
[@{findsum($need-$hash{$key},@_)}, $key ]
: undef );
Seems to work, but calls the same findsum twice with the same parameters.

Your use of plural "we" is confirmation of your flawed thinking and,
your diminished communicative skills, further exasperated by your
missing a chance to harass me for my use of a singular baited "is."
> What relevance does the OP's hash have to the question whether the knapsack
> problem is solvable in polynomial time?
What are the contents of the originating author's hash? Without
clear and concise parameters, no solution can be offered nor
can the originating author's article be reliably understood.
Is he asking a classic "knapsnack" question or not?
It is annoyingly clear you a unaware a knapsnack problem and this
"hinted" at problem of the originating author's, both have an
infinite number of solution sets. It is equally annoyingly clear
you don't have clue on just what is the knapsnack problem.
Regardless of personal interpretation by a person, any solution
offered for the author's incoherent articles, is inherently flawed
unless infinite solution sets are produced by any given code.
Incidently, enter a value of 0 (zero) or a value of 1 (one)
within your code for number of terms, this is, the flawed code
you posted under one of your fake names. I am most certain an
entered value of one will cause your brains to explode. Another
flaw is your code relies on generating the smallest possible
numbers within a solution set rather than offering purely random
solution sets. Your solution sets are nearly identical each run.
The originating author did say "random" right? Humorously, his
word "random" is about the only thing which is understandable.
Clearly my "clarity" program performs a better job, a more
imaginative job, by offering 22,084,947,919,456,858,275,840,000
solution sets, than does your "available anywhere" subset code,
which offers ever-so-boring repetitious solution sets.
I find your troll articles as boring as your are boarish.
If you keep flaunting your flawed thinking, God, in Her
infinite wisdom, is likely to issue a factory recall for
you and, others like you.
Godzilla! God's Ms. Goodwrench.

Subject: FAQ: Why don't Perl one-liners work on my DOS/Mac/VMS system?
Message-Id: <lB_57.18$zH9.189240320@news.frii.net>
This message is one of several periodic postings to comp.lang.perl.misc
intended to make it easier for perl programmers to find answers to
common questions. The core of this message represents an excerpt
from the documentation provided with every Standard Distribution of
Perl.
+
Why don't Perl one-liners work on my DOS/Mac/VMS system?
The problem is usually that the command interpreters on those systems
have rather different ideas about quoting than the Unix shells under
which the one-liners were created. On some systems, you may have to
change single-quotes to double ones, which you must *NOT* do on Unix or
Plan9 systems. You might also have to change a single % to a %%.
For example:
# Unix
perl -e 'print "Hello world\n"'
# DOS, etc.
perl -e "print \"Hello world\n\""
# Mac
print "Hello world\n"
(then Run "Myscript" or Shift-Command-R)
# VMS
perl -e "print ""Hello world\n"""
The problem is that none of these examples are reliable: they depend on
the command interpreter. Under Unix, the first two often work. Under
DOS, it's entirely possible that neither works. If 4DOS was the command
shell, you'd probably have better luck like this:
perl -e "print <Ctrl-x>"Hello world\n<Ctrl-x>""
Under the Mac, it depends which environment you are using. The MacPerl
shell, or MPW, is much like Unix shells in its support for several
quoting variants, except that it makes free use of the Mac's non-ASCII
characters as control characters.
Using qq(), q(), and qx(), instead of "double quotes", 'single quotes',
and `backticks`, may make one-liners easier to write.
There is no general solution to all of this. It is a mess, pure and
simple. Sucks to be away from Unix, huh? :-)

Yes, I use the GPIB module from the Linux lab project to talk to the

You can use Image::Magick to create counter logo from a set of images
with a numbers from 0 to 9.
Or you you can draw counter image using GD.
Both libraries are available from CPAN.

ImageMagik can also write text on an empty image.

Some intresting Perl IDEs:
Perl Builder 2.0 at www.solutionsoft.com
another one I like very much is Optiperl 3 from
http://www.xarka.com/optiperl/
and the very easy to use DZSoft Perl Editor from
http://www.dzsoft.com/dzperl.htm
Hope you find one you like ..

Paul

Thanks. This was one of the problem.
Here is the one I do not know how to solve. How can I open a file to write?
Here is the code.
delete @ENV{'IFS', 'CDPATH', 'ENV', 'PATH'};
$HostName = `/bin/uname -n`;
$ErrFilePath = "@{[ $ENV{FCICSGBLCODE} =~ /(.*)/ ]}/dbcob/dberrs.$HostName";
open(ERRFILE, ">>$ErrFilePath");
I get following error:
Insecure dependency in open while running setuid

:)
:)I do not know of any way to trace the back the cause of a tainting
:)other than manual analysis.

:)May of the luminaries of this group have their own web sites (and

Speaking as an experienced developer in a number of languages who is
very close to giving up on Silicon Valley and moving back to the UK
because of the dire state of the US hi-tech job market, I find this
thread very interesting. Please keep it going.

Message-Id: <3B587330.716E803C@apple.com>
Hi all,
Anybody know where I can get templates/styles to product Perl manpages
for:
Text HTML
Dreamweaver
Go live
Microsoft Word
Framemaker
I'm trying to avoid the tedium of working up my own formatting.
Thanks in advance :-)

Try the pod format. Info should be in the existing man pages. The format is
*very* straight forward and can be converted to HTML via pod2html (Guess
what pod2man does).
