Greetings all,
I'm trying to create a module to read an proprietary file format, and have everything working, however, I'd like to put a little sugar on it.
Instead of calling tie *FH, "thor", "myfile", I'd like to be able to mask the tie with a subroutine in the same package. Here's what I have in the package:
package thor;
use strict;
use Carp;
require Exporter;
our($VERSION, @ISA, @EXPORT);
$VERSION = "0.1";
@ISA = qw(Exporter);
@EXPORT = qw(rdw_open);
sub rdw_open(*$;@) #need a file handle and a name, but allow more for
+the 3 arg open...
{
local *fh = shift;
tie \*fh, __PACKAGE__, @_ ;
}
sub TIEHANDLE
{
my $class = shift;
my $filename = shift;
open my $self, $filename or croak "Couldn't open $filename: $!";
bless $self, $class;
return $self;
}
So, then in my script, I'd like to be able to do this:
#!/usr/bin/perl
use thor;
rdw_open(FH,"myfile") or die "Couldn't open myfile: $!";
# replaces tie *FH, "thor","myfile"
Is this possible?
Incidentally, I tried moving the rdw_open sub into my script and it works, which I find a bit strange...
