Re: regex nth match of string, perl 5.8.5
Bingo! Thanks for the replies.
Just use the non-greedy form of *:
s{(\I\)(.*?)(\I\)}{$1$2\\/I\}g
should do what you want.

Re: Array problem
Is this what you wan't ?
open INPUT,$ARGV[0];
while ($line=INPUT){
push (@array,$line);
}
foreach $i(@array){

I wrote simple script, which have to concatenate multiple lines into array
and then print each element of tihis array:
open INPUT,$ARGV[0];
while ($line=INPUT){
push (@array,$line);
foreach $i(@array){
print $i;
}
}
Input is e.g.
line 1
line 2
I don't know where is the problem, Please, help!
Cheers, Andrej

Want to add exception for a auto run sub in module
Hi all,
I have a module somewhat looks like this :
package minicgi;
require Exporter; our @ISA = qw/Exporter/;
our @EXPORT = qw/NormalHeader OtherHeader/;
sub NornalHeader { print Content-Type:text/html\n\n } # normal html
sub OtherHeader { print Content-Type:$_[0]\r\n\r\n } # perhaps sending file
NormalHeader;
1;
So, when I use minicgi, normal_header() will autorun, however,
it makes the other_header() meaningless. So my question is,
is there anyway I'll run normal_header() without specific argument,
but don't run it if I pass whatever argument on the 'use' statement ?
Thank you very much,
Jim
Re: Want to add exception for a auto run sub in module
Sorry for typing err for the sub name at the question part =(
normal_header() and other_header() should aling with the
sample code, so is NormalHeader() and OtherHeader().

Maybe I'm missing something, but the poster appears to be asking how to achieve the common and useful pattern of plugins, where you control dynamic behavior by deciding what modules are in a particular directory.

You need BEGIN blocks, glob(), and a require followed by a $class-import inside the loop. Every now and again someone gets the bright idea to load modules dynamically. Usually they do this to save time. The correct way to do this is to rewrite the modules for AutoLoader. Then you just 'use' everything.

I believe you're asking how a module can determine how it was 'use'd, so as to provide default behavior when no import list is specified. The documentation for 'use' in the perlfunc manpage covers the 'import' method, which is called when the import list is not missing; does that give you what you need?

file test
dear all,
i am trying to check if there are any files named file* (e.g.
file_001.txt file1.doc) in my directory.
if( -e file* ) { print(true\n); } # this doesn't work
else { print(false\n); }
if( -e m/^file/ ) { print(true\n); } # this doesn't work either
else { print(false\n); }
thank you in advance, any answer would be greatly appreciated.
-H.
