( #3333=superdoc: print w/replies, xml ) Need Help??
I think the subroutine is not entirely correct. Without te Carp which I don't have on my system I came up with this working version:
sub menu { my ($title, @option) = @{shift(@_)}; my (@name, @action); ($name[@name], $action[@action]) = splice @option, 0, 2 while @option; while(1) { print "\n$title\n"; print map "$_. $name[$_ - 1]\n", 1 .. @name; print '> '; chomp (my $choice = readline *STDIN); if ($choice and $choice > 0 and $choice <= @action) { my $do_action = $action[$choice-1]; return unless defined $do_action; $do_action->() if 'CODE' eq ref $action[$choice-1]; menu($action[$choice-1]) if 'ARRAY' eq ref $action[$choice-1]; + } else { print "Invalid choice: $choice\n" } } }

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
