NAME

ApacheLog::Parser::SkipList - a list of skippable lines

SYNOPSIS

  my $skipper = ApacheLog::Parser::SkipList->new;
  my %regexps = $skipper->set_config(\%conf);
  # you'll typically build %regexps into some condition sub

  my $sw = $skipper->new_writer($skipfile);
  my $counter = 0;
  while(...) {
    ...
    $counter++;
    $some_condition and $sw->skip($counter);
  }

Later, while reading a file with a prepared skiplist:

  my $skipper = ApacheLog::Parser::SkipList->new;
  $skipper->set_config(\%conf);

  my $sr = $skipper->new_reader($skipfile);
  my $skip = $sr->next_skip;
  my $counter = 0;
  while(my $line = <$fh>) {
    if(++$counter == $skip) {
      $counter += $sr->skip_lines($fh);
      $skip = $sr->next_skip;
      next;
    }
    
    # then do more expensive stuff
    ...
  }
