Re: [MacPerl] perldoc on Mac

[Chris Nandor <pudge@pobox.com>]

OK, one last one.  It didn't like some bareword eval'd strings, and didn't
quit gracefully on some cancels.  Also speed up initial execution with
delayed require instead of use.

#!perl
# macperldoc a.k.a. perldoc/2
# requires IC setup to use Shuck for pod URLs
use strict;
my($what, $why, $where, $ic, %help);

$what = MacPerl::Ask('What do YOU want?') or exit;
($why = $what) =~ s|::|/|g; $why .= '.pm';
eval("require '$why'");

if (!$@) {
  $where = $INC{$why};
} elsif (-e "$ENV{MACPERL}pod:$what.pod") {
  $where = "$ENV{MACPERL}pod:$what.pod";
} else {
  require DB_File;
  require Fcntl;
  tie(%help, 'DB_File', "$ENV{MACPERL}MacPerl Help",
    Fcntl::O_RDONLY(), 0) or die $!;
  if (defined($help{$what})) {
    ($where = $help{$what}) =~ s|^pod:|$ENV{MACPERL}|;
    $where =~ tr|/|:|;
  }
}

if (!$where) {
  MacPerl::Answer("Cannot find $what.");
  exit;
} else {
  require Mac::InternetConfig;
  Mac::InternetConfig->import();
  $ic = ICStart();
  ICGeneralFindConfigFile($ic);
  ICLaunchURL($ic, 0, "pod:///$where");
  ICStop($ic);
}
__END__
