( #3333=superdoc: print w/replies, xml ) Need Help??

Right off the bat, this is what I thought of:

sub balance_by { my ($self,$entry) = @_; my %valid_params = map {$_ => 1} qw/ foo bar /; $self->{'balance_by'} = (defined $entry and exists $valid_params{$ +entry}) ? $entry : 'foo'; return $self->{'balance_by'}; }

The only real change is the removal of the unless logic. What that does is set the "balance_by" if you have a valid $entry>, else it sets it to the default "foo". However, it seems to me that you wanted a one-time setting of balance_by that could not be changed. Is that correct? In your code "foo" will only be used as a default on the first pass.

So, if I understood what you wanted, my code will always set balance_by to $entry if you have a valid $entry. If it's not valid, it sets it to "foo".

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.
