The way file handles work is another reason to dislike Perl. At
least, I've always found them confusing.
The Perl5 file handles are different. This example is for reading a file.
Really, the arguments to "new" are the same arguments open accepted.:
require 5.004;
use IO::File;
my $fh = new IO::File " filetoread";
while ($fh-getline)
{
dostuff $_;
}
The other functions available for old style file handles are similar. These
are just front ends for the old Perl builtins, but context switching just
happens automatically now. e.g. $fh-eof, $fh-print, $fh-open (usually
called implicitly with arguments to new), $fh-close (unnecessary - "undef
$fh" will autoclose), $fh-autoflush, $fh-fileno, etc.
"$fh-getlines;" will work like calling $fh in an array context.
"my $line = $fh-getline;" "my @lines = $fh-getlines;" (to read an entire
file) are valid constructs. I don't remember if the same was true of , but
I think so.
P.S. You probably won't need to know, but Perl5 prior to 5.004 used
FileHandle in lieu of IO::File, and FileHandle is still supported as a front
end for IO::File, but is deprecated.
