Template Toolkit output to a scalar?

theguvnor has asked for the wisdom of the Perl Monks concerning the following question:

I'm looking for the easiest way to redirect the output from TT2's process() method to a scalar, as opposed to STDOUT. Suggestions? (I am trying to avoid having to shell out to use tpage, if possible.)

Update: I looked at the template docs manual and did not see that. --me! Anyway, thanks for the lightning fast responses - I now see it in the perldoc page.

    According to the Template docs, the third param to process can be a SCALAR ref - just pass in a ref to the variable you want to receive it.

    #!/usr/bin/perl use strict; use warnings; use Template; my $data = { name => 'Ovid' }; my $template = Template->new; my $output; $template->process(\*DATA, $data, \$output); print $output; __DATA__ Hello, [% name %]

    In general, you can open a scalar as though it were a file.
    my $fake_file; open(my $fh, ">", \$fake_file) or die $!; print $fh, "foo\n"; print $fh, "bar\n"; print $fake_file;
    According to perldoc -f open, you can do this with STDOUT, you just have to close it first.

      Now *that* is cool. Definitely hadn't stumbled on that tidbit. ++thor
