( #3333=superdoc: print w/replies, xml ) Need Help??
This seems to work. Posting it in case someone else finds it helpful.
package MakeMethod; use strict; use base qw( Class::MethodMaker ); sub new_hash_init_required { my ($class, @args) = @_; my %methods; foreach (@args) { $methods{$_} = sub { my $class = shift; my $self = ref($class) ? $class : bless {}, $class; my %args = (scalar @_ == 1 and ref($_[0]) eq 'HASH') ? %{ +$_[0]} : @_; foreach (keys %args) { if (my $setter = $class->can(" __CMM__ $_")) { $setter->($self, $args{$_}); } else { $self->$_($args{$_}); } } die "must specify required" unless $self->can("required"); my @req = $self->required; foreach my $req (@req) { die "$req does not exist" unless exists($self->{$req}) +; } $self; }; } $class->install_methods(%methods); } sub required { my ($class, @req) = @_; my %methods; $methods{required} = sub { @req }; $class->get_set(@req); $class->install_methods(%methods); } 1;
While I had trouble grasping the C:MM docs, reading the source made it much clearer.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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.
