hmmm. Something is wrong that I can't figure out: 

#!/usr/bin/perl -w

use strict;
use Text::Template;


my %vars;
my $line;
my @fields;
my $result;

my $file = "/home/trixee/20010814/remap.tmpl";
my $cfg = "/home/trixee/20010814/remap.config";
my $template = new Text::Template (SOURCE => $file)
  or die "Couldn't construct template: $Text::Template::ERROR";

open FH, "$cfg" or die "$!\n";

while ($line = <DATA>)
  {
    chomp $line;
    next if ($line =~ /^\#/);
        
    @fields = qw(map proto uri1 uri2);
    
    if ( @vars{@fields} = $line=~m!(map|reverse_map)\s+(\w+)://(.*?)\s
++\2://(.*?)$! )
      {      
 $result = $template->fill_in(HASH => \%vars);
      }
    
    if ($result) 
      {
print "$result\n";
      }
    else 
      { 
 die "Couldn't fill in template: $Text::Template::ERROR"
      }
 }

Why?

In reply to Re: Re: Reading in N lines at a time by Tuna
in thread Reading in N lines at a time by Tuna

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
