Perl Regex named capture variables

Simple example to extract, protocol, server and domain from a given URL:

my $test = "http:www.test.com";

$test =~ /^(?<protocol>.+)\:(?<server>.+)\.(?<domain>.+)$/;

print "protocol : ".$+{protocol}."\n";
print "Server   : ".$+{server}."\n";
print "Domain   : ".$+{domain}."\n";

my $test = "http:www.test.com";

$test =~ /^(?<protocol>.+)\:(?<server>.+)\.(?<domain>.+)$/;

print "protocol : ".$+{protocol}."\n";

print "Server : ".$+{server}."\n";

print "Domain : ".$+{domain}."\n";

Our Result:

sh-4.3$ perl main.pl 
protocol : http      
Server   : www.test 
Domain   : com

sh-4.3$ perl main.pl

protocol : http

Server : www.test

Domain : com

Perl find all pow 2 numbers

This little script finds all pow 2 numbers in Perl :

use strict;
my $number = 0;

for(1..32){
    ++$number;
    print "$number - ".isPow2($number)."\n";
}


sub isPow2 {
    return(0) if($_[0] <= 0);
    return(1) if($_[0] == 1);
    for(1..$_[0]){
       return(1) if($_[0] == 2**$_)
    }
    return(0);
}

use strict;

my $number = 0;

for(1..32){

++$number;

print "$number - ".isPow2($number)."\n";

}

sub isPow2 {

return(0) if($_[0] <= 0);

return(1) if($_[0] == 1);

for(1..$_[0]){

return(1) if($_[0] == 2**$_)

}

return(0);

}

Our Result:

1 - 1

2 - 1

3 - 0

4 - 1

5 - 0

6 - 0

7 - 0

8 - 1

9 - 0

10 - 0

11 - 0

12 - 0

13 - 0

14 - 0

15 - 0

16 - 1

Perl print String difference

This function prints the difference between two strings with Perl:

sub printStringDiff{
my ($s1, $s2) = @_;

my @s1 = split(//, $s1);
my @s2 = split(//, $s2);
while (@s1) {

    if (defined $s1[0] and defined $s2[0]) {
    	if($s1[0] eq $s2[0]){
			print shift @s1;
		}else{
			print color("red"),shift @s1, color("reset");
		}
    }elsif(defined $s1[0]){
    	print color("red"),shift @s1, color("reset");
    }
    shift @s2;
}
print "\n";

@s1 = split(//, $s1);
@s2 = split(//, $s2);
while (@s2) {

    if (defined $s2[0] and defined $s1[0]) {
		if($s2[0] eq $s1[0]){
			print shift @s2;
		}else{
			print color("red"),shift @s2, color("reset");
		}
    }elsif(defined $s2[0]){
    	print color("red"),shift @s2, color("reset");
    }
    shift @s1;
}
print "\n";
}

sub printStringDiff{

my ($s1, $s2) = @_;

my @s1 = split(//, $s1);

my @s2 = split(//, $s2);

while (@s1) {

if (defined $s1[0] and defined $s2[0]) {

if($s1[0] eq $s2[0]){

print shift @s1;

}else{

print color("red"),shift @s1, color("reset");

}

}elsif(defined $s1[0]){

print color("red"),shift @s1, color("reset");

}

shift @s2;

}

print "\n";

@s1 = split(//, $s1);

@s2 = split(//, $s2);

while (@s2) {

if (defined $s2[0] and defined $s1[0]) {

if($s2[0] eq $s1[0]){

print shift @s2;

}else{

print color("red"),shift @s2, color("reset");

}

}elsif(defined $s2[0]){

print color("red"),shift @s2, color("reset");

}

shift @s1;

}

print "\n";

}

You need the Module Term::ANSIColor, to highlight the changes,use it like this:

#!/usr/bin/perl
use strict;
use Term::ANSIColor;

printStringDiff("1234","123456");
print "\n";

printStringDiff("123456","1234");
print "\n";

printStringDiff("ABAA","AABA");
print "\n";

#!/usr/bin/perl

use strict;

use Term::ANSIColor;

printStringDiff("1234","123456");

print "\n";

printStringDiff("123456","1234");

print "\n";

printStringDiff("ABAA","AABA");

print "\n";

And the Result is :

Perl check if file handler is open

If you write a function in Perl and want to check if the file handler is already open you could use this function:

sub filehandlerOpen {
	my $fh = shift;
	no warnings 'uninitialized';
	return 0 if(!defined $fh || $fh !~ /^GLOB\(0x.+?\)$/);
	if(fileno($fh) >= 1){
		return(1);
	}
	return(0);
}

sub filehandlerOpen {

my $fh = shift;

no warnings 'uninitialized';

return 0 if(!defined $fh || $fh !~ /^GLOB$0x.+?$$/);

if(fileno($fh) >= 1){

return(1);

}

return(0);

}

It returns 0 if its undefined,closed or not open, an 1 if the handler is open.

In this little example I open a file to read and another to write, I check the sub before and after the open function, and before and after the close function.

#!/usr/bin/perl
use warnings;
use strict;

my ($fh_read,$fh_write);

print "Check undefined:\n";
print filehandlerOpen($fh_read).$/;
print filehandlerOpen($fh_write).$/;


open($fh_write, ">", './testfile') or die "Failed to open file: $!\n";
open($fh_read, "<", './testfile') or die "Failed to open file: $!\n";


print "Check defined:\n";
print filehandlerOpen($fh_read).$/;
print filehandlerOpen($fh_write).$/;


for my $num (1..6){
	print $fh_write "$num\n";
}
print "Check close write:\n";
print filehandlerOpen($fh_write).$/;
close($fh_write);
print filehandlerOpen($fh_write).$/;


while (my $row = <$fh_read>) {
  chomp $row;
}
print "Check close read:\n";
print filehandlerOpen($fh_read).$/;
close($fh_read);
print filehandlerOpen($fh_read).$/;


sub filehandlerOpen {
	my $fh = shift;
	no warnings 'uninitialized';
	return 0 if(!defined $fh || $fh !~ /^GLOB\(0x.+?\)$/);
	if(fileno($fh) >= 1){
		return(1);
	}
	return(0);
}

#!/usr/bin/perl

use warnings;

use strict;

my ($fh_read,$fh_write);

print "Check undefined:\n";

print filehandlerOpen($fh_read).$/;

print filehandlerOpen($fh_write).$/;

open($fh_write, ">", './testfile') or die "Failed to open file: $!\n";

open($fh_read, "<", './testfile') or die "Failed to open file: $!\n";

print "Check defined:\n";

print filehandlerOpen($fh_read).$/;

print filehandlerOpen($fh_write).$/;

for my $num (1..6){

print $fh_write "$num\n";

}

print "Check close write:\n";

print filehandlerOpen($fh_write).$/;

close($fh_write);

print filehandlerOpen($fh_write).$/;

while (my $row = <$fh_read>) {

chomp $row;

}

print "Check close read:\n";

print filehandlerOpen($fh_read).$/;

close($fh_read);

print filehandlerOpen($fh_read).$/;

sub filehandlerOpen {

my $fh = shift;

no warnings 'uninitialized';

return 0 if(!defined $fh || $fh !~ /^GLOB$0x.+?$$/);

if(fileno($fh) >= 1){

return(1);

}

return(0);

}

The Result, looks like expected:

Check undefined:
0
0
Check defined:
1
1
Check close write:
1
0
Check close read:
1
0

Check undefined:

Check defined:

Check close write:

Check close read:

Perl print DATA multiple times

Sometimes you have a lot of Data in Perl and you want to store in your script, for that you could you the __DATA__ token, you could simple read it with a file handle:

print <DATA>,"\n";

__DATA__
Test String
123456

print <DATA>,"\n";

__DATA__

Test String

123456

If you use it more than one time you should seek for the start position:

#!/usr/bin/perl
use warnings;
use strict;



my $data_start = tell DATA; # where __DATA__ begins
print <DATA>,"\n";
seek DATA, $data_start, 0;

print <DATA>,"\n";

__DATA__
Test String
123456

#!/usr/bin/perl

use warnings;

use strict;

my $data_start = tell DATA; # where __DATA__ begins

print <DATA>,"\n";

seek DATA, $data_start, 0;

print <DATA>,"\n";

__DATA__

Test String

123456

Output looks like this:

Test String
123456

Test String
123456

Test String

123456

Test String

123456

This is a simple example how to write into a File with Perl, and then read from it.At first we write the numbers from 1 to 6 into the file, in the second we read from the file and print it on the screen, if you don’t want the “\n” at the end use the function chomp.

If you open a File for read use ‘<‘, for write ‘>’ and for append ‘>>’.

#!/usr/bin/perl
use warnings;
use strict;

#declare filehandler
my ($fh_read,$fh_write);


#open file for write
open($fh_write, ">", './testfile') or die "Failed to open file: $!\n";

#now write
for my $num (1..6){
	print $fh_write "$num\n";
}

#close the file
close($fh_write);


#open file for read
open($fh_read, "<", './testfile') or die "Failed to open file: $!\n";

#now read
while (my $row = <$fh_read>) {
  print $row;
}

#close the file
close($fh_read);

#!/usr/bin/perl

use warnings;

use strict;

#declare filehandler

my ($fh_read,$fh_write);

#open file for write

open($fh_write, ">", './testfile') or die "Failed to open file: $!\n";

#now write

for my $num (1..6){

print $fh_write "$num\n";

}

#close the file

close($fh_write);

#open file for read

open($fh_read, "<", './testfile') or die "Failed to open file: $!\n";

#now read

while (my $row = <$fh_read>) {

print $row;

}

#close the file

close($fh_read);

Result looks like:

you could check if a handler is open with this Perl handler function.

INSTALL RPM under Debian

If you want to install *.rpm files under Debian you could use alien.

apt-get install alien
alien -i package.rpm

1 2	apt-get install alien alien -i package.rpm

Perl find lowest divisible number

This Perl Script find the lowest, divisible number from 1 to 10:

use strict;
my ($number,$check) = (0,0);
while(1){
    ++$number;
    $check=0;
    for(1..20){
        unless($number%$_==0){++$check;last;}
    } 
    last unless($check);
}
print "$number\n";

use strict;

my ($number,$check) = (0,0);

while(1){

++$number;

$check=0;

for(1..20){

unless($number%$_==0){++$check;last;}

}

last unless($check);

}

print "$number\n";

The result is 2520.

Fraction calculation in Perl

This Perl script is able to add,subtract,divide and multiply fractional numbers:

use strict;
#test data:

            $D[0] -= $D[1];
            ++$c;
        }else{
            last;    
        }
    }
    if($c){
        return "$c+$D[0]/$D[1](".&fractial2number.")\n"; 
    }else{

    print "fractal number:";
    my $in = <STDIN>;
    if($in =~ /\//o){
       $in =~ /^(.+)\/(.+)$/o;
        return($1,$2);
    }else{

}

sub _print {

$D[0] -= $D[1];

++$c;

}else{

}

if($c){

return "$c+$D[0]/$D[1](".&fractial2number.")\n";

$u = "1".$u;

return($c+($d*$u),"$u");

}

sub fractial2number {

return($_[0]/$_[1]);

}

sub simplify {

for($_ = $_[1];$_>=2;--$_){

return($_[0]/$_,$_[1]/$_) if($_[0]%$_==0 && $_[1]%$_==0);

}

return($_[0],$_[1]);

}

This is the output from 1/2 and 1.25, at first add both then subtract from the result, multiply and then divide from the result:

fractal number:1/2  
fractal number:1.25 
+:1+3/4(1.75)       
-:1/2(0.5)          
*:5/8(0.625)        
/:1/2(0.5)

fractal number:1/2

fractal number:1.25

+:1+3/4(1.75)

-:1/2(0.5)

*:5/8(0.625)

/:1/2(0.5)

For a better result take a look at Perl high precision.

JavaScript generate an result array from XPATH

This is a function in JavaScript that use an XPATH string to generate an Array from the results.This is very useful if you have to manipulate or use some items on a page and don’t have the id(like bots).

That is the function:

function matches2array (XPATH){
  var links = new Array();
  var elements = 0;
  var xPathRes = document.evaluate (XPATH, document, null, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null);
  var actualSpan = xPathRes.iterateNext ();
  while (actualSpan) {
    links[elements] = actualSpan;
    actualSpan = xPathRes.iterateNext ();
    ++elements;
  }
  return(links);
}

function matches2array (XPATH){

var links = new Array();

var elements = 0;

var xPathRes = document.evaluate (XPATH, document, null, XPathResult.ORDERED_NODE_ITERATOR_TYPE, null);

var actualSpan = xPathRes.iterateNext ();

while (actualSpan) {

links[elements] = actualSpan;

actualSpan = xPathRes.iterateNext ();

++elements;

}

return(links);

}

You could use it in the Terminal:

matches2array("//a");

1	matches2array("//a");

Use it to store it in an Array and then write it on the page:

var scripts = matches2array("//a");

for (i=0;i<scripts.length;i++){
document.write(scripts[i] + "\n");
}

var scripts = matches2array("//a");

for (i=0;i<scripts.length;i++){

document.write(scripts[i] + "\n");

}

and we got this result:
