Re: Template Toolkit output to a scalar?

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.

Open-scalar-as-file is only in fairly recent Perls though (5.8 perhaps?). So if your code has to be portable (such as a CPAN submission), don't do that... yet. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]

Definitely 5.8. You can do something similar with IO::Scalar with 5.6 - I've got code that checks the perl version, and if 5.8, uses the \$scalar trick, but if 5.6, uses IO::String. Which, of course, doesn't actually come with 5.6, but if you are making a CPAN submission, you can easily put a pre-req on IO::String. Maybe not quite as easy to do if you only want the pre-req for 5.6, but still possible.	[reply]
