(jeffa) 3Re: How can read form __DATA_

Bug in HTML::Template? What are you talking about? No offense, but something tells me that you are overlooking something on your side and you are thinking that it is a bug in that module (at the most i wager it's a feature that samtregar never intended HTML::Template to do). Abigail-II's solution is right on ... nobody says that you ever need use the <> operator to pass a package's DATA filehandle around (and it is filehandle by the way, not filehandler ... you aren't handling a file, you are getting a handle on the file). Here is some code to demonstrate:

We call a package's (Foo) subroutine which returns an object to us (Bar). Bar contains one 'attribute' whose value is a reference to Foo's DATA filehandle. Back inside main we instantiate a new HTML::Template and pass Bar's 'filehandle' it to (which is really a reference to Foo's). We then pass it a param for it to substitute and then we print the output. Here goes:

use strict;
use warnings;
use HTML::Template;

my $bar = Foo::do_it();

my $tmpl = HTML::Template->new(filehandle => $bar->{filehandle});
$tmpl->param(baz => 'Hello GLOB!');
print $tmpl->output();

package Bar;
sub new {
    my $class = shift;
    return bless {@_}, $class;
}

package Foo;
sub do_it {
    my $bar = Bar->new(filehandle => \*DATA);
    return $bar;
}

__DATA__
<html>
<body>
<h1><tmpl_var baz></h1>
</body>
</html>

Finally note, i tend to use DATA only for tests and example scripts - i avoid it when it comes to writing real production code. Use seperate files instead. I guess if you have each page associated with one and only one module it would make sense ... but i tend to associate multiple pages with each module (add, edit, view, delete, list all, etc.) ... Inline::Files? Nah! ;)

Best of luck to you and please let us know how your progress goes. :)
