Expand a Hex number range with PERL

[fil66]

Hi There,

Is it possible to expand Hex number range?

Here is what I have in a text file...

002A:002F
03E0:03E0
03E2:03E2
07AF:07B1
0212:0212
0248:0248

I would like to expand the range (when there is a range) and have all including the leading 0's.

Here is the output I am looking for...

002A
002B
002C
002D
002E
002F
03E0
03E2
07AF
07B0
07B1
0212
0248

All the information I found was to convert a Hex number.... any help would be appreciated.

Thanks, Fil

why not split each range using the ":" as the delimiter and put each element into an array. Then, sort the array and print it. Just an idea. Try to do it, then if you get stuck, paste your code here.

Call me generous today, but I threw this together quickly and tested it against the sample you provided. It should work for you:

#!/usr/bin/perl
 
use warnings;
use strict;
 
 
open(FILE, "<data.txt") or die "Unable to open data file:  $!";
 
my @hexarray;
my $line;
my $var1;
my $var2;
 
while(<FILE>){
    $line = $_;
 
    ($var1, $var2) = split(/\:/, $line);
 
    chomp($var2);
    push(@hexarray, $var1);
    push(@hexarray, $var2);
}
 
foreach my $hexvalue(sort(@hexarray)){
    print("$hexvalue\n");
}

WOW... that is fantastic.. Thank you numberwhun..

It does exactly what I need plus keeps the number format (all leading zeros)...
Appreciate your time..JFC

Anytime! Glad it works for you.

This gives you the output you requested. It is necessary to convert your strings to hex first:

use strict;
use warnings;
 
while (<DATA>) {
    chomp;
    my ($n1, $n2) = split /:/;
    for (hex($n1) .. hex($n2)) {
        printf "%04X\n", $_;
    }
}
__DATA__
002A:002F
03E0:03E0
03E2:03E2
07AF:07B1
0212:0212
0248:0248

Jeff,

When I run your code, I don't see 002B, 002C, etc., as in the original question.

[numberwhun]

Ah, that was my mistake. Good catch @toolic!

Jeff

Thanks toolic for catching it... very important to have all the devices in between.
I tried your Perl scritp and keep getting an error ... I am not sure what I am doing wrong.

Here is the error
C:\>\expandrange.pl
Illegal hexadecimal digit 'T' ignored at \expandrange.pl line 7.
Use of uninitialized value $n2 in hex at \expandrange.pl line 7.

same data with a file name DATA.txt

Can you please post your code so we may see it?

Thanks!

Jeff

Thanks Jeff.... Here is the what I used on windows OS..

use strict; 
use warnings; 
 
while (<DATA.txt>) { 
    chomp; 
    my ($n1, $n2) = split /:/; 
    for (hex($n1) .. hex($n2)) { 
        printf "%04X\n", $_; 
    } 
}
