Re: Re: 'strict refs' + 'strict sub' = suck.

Roger, you've pimped the use of IO::File over open once before in Re: Removing duplicates from list yet you never state why you think IO::File is better. I'm honestly curious as to why you prefer one over the other. Is it just because IO::File uses OO syntax?

Re: Re: Re: 'strict refs' + 'strict sub' = suck. by Roger (Parson) on Oct 26, 2003 at 00:05 UTC
Since Perl 5.6.0 we can perform file operations using a scalar - which is quite convenient to pass around in function calls. For example - `open my $fh, ">output.txt" or die "Can't create output: $!"; print {$fh} "Hello world!\n"; close $fh; # if don't close, then it will be closed # automatically when $fh is out of scope.` [download] However the above code is not valid in version of Perl prior to 5.6.0, which I am still using on some of the production boxes. However the following will work on Perl prior to 5.6.0. `my $fh = IO::File "output.txt", "w" or die "Can not create output: $!"; print $fh "Hello world!\n"; undef $fh;` [download] My preference of IO::File over open is on the Perl version compatibility and also ease of use. This is only my personal perference however.	[reply] [d/l] [select]

open my $fh, ">output.txt"
    or die "Can't create output: $!";
print {$fh} "Hello world!\n";
close $fh;  # if don't close, then it will be closed
            # automatically when $fh is out of scope.

my $fh = IO::File "output.txt", "w"
   or die "Can not create output: $!";
print $fh "Hello world!\n";
undef $fh;
