RE: Formatting integer input: use the sprintf() in perlfunc - Perl builtin functions
Sara, whenever you need to do any special formatting like this, especially numbers, use the sprintf() in perlfunc - Perl builtin functions for your case, try this: print sprintf(%05.02f\n, 4.5 ); 04.50 there are 2 other print formatters: report and here documents. I don't use the report method because I prefer the here documents. A here document is very nice, yet hardly documented within perl. It involves just a TAG and a 2 special rules, here's and example: print MY_TAG; I can put anything in here and it will be exactly that. I can put the variable three=$three, I can put @vars in here. Everything expands. What's great is that there isn't all that print ... with special characters! The above statement could require some escaping of the single quote in print statements. Now, The 2 rules: #1 - the and the tag name MY_TAG must be together, ie, no spacing. #2 - the end tag MUST be in column 1 and nothing else, ie, no end ; so here's the end of this. MY_TAG You can store the here doc as a variable: my $message = MY_TAG; stuf MY_TAG cheers, -stuart -Original Message- From: Sara [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 20, 2003 1:21 PM To: beginperl Subject: Formatting integer input $one = 2.5; $two = 2; $three = $one + $two; print $three; # prints 4.5 I want 4.5 in proper format as 04.05 Any ideas?

Re: Secure Form Submission
It seems like it should be secure. I am assuming the session cookie would store the server's public key? or some such? My question would be how do you implement an RC4 encryption (or any encryption other than the built-in SSL) on the client side? Possibly a Java applet with the encryption built-in? I suppose you could implement an encryption algorithm in javascript and then just call that via a form's onSubmit, but how would you generate a random number (built into javascript?)... yikes thats a lot of javascript :-)... and at that point you would also have to generate a private key on the client side, and send the corresponding public key to the server... and this would have to be done each time which could get slow... That was basically the plan, use the cookie to transport the key. Your comment about a lot of Javascript is precisely the daunting part. I saw in your other post about the limited IPs, if this really is a temp solution, the implementation difficulty still might suggest springing for extra hosting, or the similar until the upgrade is in place...

RE: About Shift
Yes because your not shifting any values just a memory address.
Here this might help
---
When you do your sub call
mysub ($myvar, $myvar2)
An array is created in your subroutine that holds both those values. It
is called @_.
So in the sub
@_ holds ($myvar, $myvar2),
So $_[0] = $myvar.
All shift does is empty the @_ array
So my $newvar = shift
Would give $newvar the value of $_[0] and remove it from the array
So now the array @_ only holds $myvar2 and it is now $_[0]. The first
varirable was shifted out of the array.
Now as to your question. Your not passing an array just the memory
location of it.
Which is something along the lines of...
ARRAY(0x185f3fc)
That is it. Just that string is all that is in $value of your sub
routine.
Just that string which happens to be an address to the REAL array.
You can test this. Simply add a print statement to your routine that
prints $value and you will see what I mean.
When you want to use the values of the array you dereferance it which is
why you are using double $$ or @$
Which reads as the string value contained at this mememory address.
So $$value[0] literaly means use the array item 0 contained at the
memory address of $value.
Its confusing. You should read up on refreances. Or if your not ready to
use them pass the whole array by removing the \ in the sub call. This
will send the entire array to your subroutine actually it passes a copy
of the array so that changes made in the sub don't affect the real
array.
You could also leave the array as a global variable and not pass it at
all and just use the array like you would anywhere else.
BUY learning perl by oriely. You can blow through it in an afteroon and
it will clear up a lot of this a lot better then I can explain.
I am Ccing the list so that others can contribute. Also if others are
having the same questions you are having it will benefit them. I don't
mind you mailing me directly but if its perl related send a copy to the
list for everyones benefit.
I think I just confused my self :)

RE: Read dir / sort
Ok tested that theory and it is exactly what it is doing. That is not a
good thing. How can I force it to read the directory based on file date
instead of the way windows last sorted it. That does not seem right to
me that it would function like this.

Mildly tested (and ugly) but how 'bout replacing this with something to
the effect of:

That will only change the first letter of the first word after 'SCTN:'.
That's what you're seeing, right? If you want to change *all* the words
after SCTN: to start with uppercase (and leave the ones before it alone),
maybe something like this:
my $text = q(leave this alone SCTN: this isn't capitalized but should be);
if (/SCTN:/) {
my ($before, $after) = split /SCTN:/, $text, 2;
$after =~ s/(\S+)/\u$1/g;
$text = $before . 'SCTN:' . $after;
}
print $text;
I used \S instead of \w in an attempt to handle contractions such as
can't and don't, etc.
Now I'd almost bet someone (John Krahn?) will come up with a more clever
approach and make it into a one-liner. :-)

This seems to work, although there are some odd line returns
You mean the automatic \n with every print? It's because of the -l
switch in the #! line. See perlrun(1) manpage:
http://www.perldoc.com/perl5.8.0/pod/perlrun.html#-l%5boctnum%5d
I like to use it in simple programs, as it makes them cleaner without
all of those explicit newlines, but you can just remove the -l switch
and have a standard print behavior. (Keep the -w, however, it turns on
warnings. Or better yet use use warnings; pragma.)
and '0' is being returned as '0.'
Still, I can work around that, THANKS!
Yes, indeed. I checked out the source of Math::BigFloat and
unfortunately the class name is hardcoded all over the place (it's
probably fixed in newer versions) so it's hard to subclass, but this is
Perl, after all, so we can redefine the overloaded stringification
operator in the Math::BigFloat class itself:
use Math::BigFloat;
{
package Math::BigFloat;
use overload '' = sub {(my $n = $_[0]-stringify) =~ s/\.$//; $n};
}
Now it prints just 0 without the . at the end. But note that such a
code will stop working if the stringify method in Math::BigFloat is ever
renamed. Unlikely, but possible. It's probably not the most elegant way
to program, still it's pretty cool.
You could store the \{'Math::BigFloat::('} reference to have the
original stringification method even if it's renamed (anyone knows if
it's documented somewhere?) but it could introduce another problems with
overload.pm implementation.
The code I wrote gives a warning about the ( subroutine being
redefined in overload.pm when the script is run with the -w switch, but
(at least on my system) it doesn't print the warning if there's use
warnings; instead of -w, which is better anyway.

Perl isn't doing anything but calling the OS's underlying readdir(2) call.
You shouldn't make any assumptions about the order in which readdir()
returns files. If you need them in some particular order, read them and then
sort them.

Files are not stored on the file system in any predefined order. If
they appear to be in some order then that is just a coincidence. If you
want the file names in a certain order then you will have to sort them
yourself.

Well, let's see if we can get a little closer:
s/(SCTN:\s*)(.+)$/join '', $1, map { ucfirst $_ } split /( )/, $2/ge;
See if that helps any.
