r.biswas:
I'd suggest writing a subroutine to read all your configurations into an array, and then when processing the input file you can simply load the current configuration. Something like:
my @configurations;
load_configurations("config_file");
open my $FH, '<', $input_fname or die "Can't open $input_fname: $!";
while (<$FH>) {
my @config_vars;
... parse out an input entry ...
@config_vars = @$configurations[$configuration_ID];
... code to process input using configuration variables...
}
sub load_configurations {
my $fname = shift;
open my $FH, '<', $fname or die "Can't open $fname: $!";
while (<$FH>) {
my @config_vars;
... parse out a configuration...
$configurations[$configuration_ID] = [ @config_vars ];
}
}
This way, you have all the configurations at your fingertips, and you can process each input entry with a different configuration, if desired.
