How do I get Pod::Simple to extract pod from its containing file?
With Pod::Parser, you just do parse_from_file($in_fh, $out_fh) and it outputs the pod to $out_fh. Pod::Simple has a method of the same name which is supposed to emulate the Pod::Parser method, but when I run it, nothing is output.

Pod::Parser did that but Pod::Simple doesn't, so it's possible if you're doing something short that the entire output was still buffered. Pod::Man and Pod::Text use this Pod::Simple method and do have test suites for it and it seems to work. See the attached program. The resultant file is 0 length. simple.pl Description: Perl program

I misunderstood, sorry. parse_from_file() does indeed invoke the parser with the appropriate actions, but what you meant was that Pod::Parser's null parser, when not subclassed, just printed the POD back out again, so you could use it as a way to extract the POD from a file. I believe Pod::Simple's null parser does nothing at all, so you get an empty file. Yes. I think that's an incompatibility. If I turn on DEBUGing, it's doing a lot. Is there some trivial way to extract the pod?
