I have a subroutine that is called from many other packages. I need this subroutine to read the contents of __DATA__ from the package that called it and then do something with it (__DATA__ will contain a default template for html output). I have tried something like this:
package TMPL;
sub fodus {
my $caller = (caller(0))[0];
my $out = join('',<{$caller .'::DATA'}>);
# do stuff to $out
return $out;
}
but that didn't work. I even tried this just to see if it would work if I hard-coded in the caller's package name:
package TMPL;
sub fodus {
my $out = join('',<Caller::DATA>);
# do stuff to $out
return $out;
}
But it still complained that Caller::DATA was only used once. In both of these examples I'm using strict with warnings. So how exactly can I access the contents of __DATA__ in a different package?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
