I can't exactly wrap my head around TIE just yet but the examples ( example-1 example-2 example-3 ) I've seen so far use a non-Moosy implementation, is there anyway to do this:
package MY_STDOUT;
use strict;
my $c = 0;
my $malformed_header = 0;
open(TRUE_STDOUT, '>', '/dev/stdout');
tie *STDOUT, __PACKAGE__, (*STDOUT);
sub TIEHANDLE {
my $class = shift;
my $handles = [@_];
bless $handles, $class;
return $handles;
}
sub PRINT {
my $class = shift;
if (!$c++ && @_[0] !~ /^content-type/) {
my (undef, $file, $line) = caller;
print STDERR "Missing content-type in $file at line $line!!\n";
$malformed_header = 1;
}
return 0 if ($malformed_header);
return print TRUE_STDOUT @_;
}
1;
use MY_STDOUT;
print "content-type: text/html\n\n"; #try commenting out this line
print "<html>\n";
print "</html>\n";
In a more Perl-Moosy way?
For example should I do
open(TRUE_STDOUT, '>', '/dev/stdout');
tie *STDOUT, __PACKAGE__, (*STDOUT);
in a BUILD{} function?
Would it make more sense to implement this as a Moosy class or as Moose::Role?
And finally, would I have to do something like
my $MY_STDOUT = MY_STDOUT->new();
to use it?
