Getoptions, pod2usage, oh my!

Post #231,840 by pwhysall 11/1/05 4:05:23 AM Reply	Getoptions, pod2usage, oh my! I'm puzzled as to why this fragment isn't behaving as expected: # Process command-line arguments\nmy $pco_dir = '';\nmy $rcc_dir = '';\nmy $out_dir = '';\nGetOptions ("pco=s" => \\$pco_dir,\n "rcc=s" => \\$rcc_dir,\n "out=s" => \\$out_dir, \n "debug" => \\$debug) or pod2usage(2); The intention is that if any option other than "--debug" is omitted, then I'll print the bit of my pod documentation. Only I don't; I carry on past this point. Pod documentation is hunkydory; I tested this with pod2html. Have I missed something?

Post #231,843 by pwhysall 11/1/05 4:27:04 AM Reply	Interim solution pod2usage(1) unless $pco_dir && $rcc_dir && $out_dir; I'd really rather specify in the Getoptions call that those arguments are all mandatory.

It just knows whether it managed to process the command-line options. BTW a random hint. I like to do this: \nGetOptions(\n "foo=s" => \\ my $foo,\n "bar=i" => \\ my $bar,\n);\n if I'm not trying to initialize defaults. If you want a command-line processor that can figure out required arguments, then I'd suggest Getopt::Declare or Getopt::Euclid. (The latter looks more interesting to me.) But note that since I work in a code-base that has established conventions around Getopt::Long, I have not bothered experimenting with those.
