Hello davies,
I'm not a OO expert (in what I'm expert? ;) but I almost always start with something like (perl 5.14 5.10 (see below GrandFather's answer) required to use //= ):
sub new{
my $class = shift;
my %conf = validate_conf( @_ );
return bless {
%conf
}, $class;
}
sub validate_conf{
my %conf = @_;
$conf{ map_colors } //= 16;
$conf{ map_area_w } //= 50;
$conf{ map_area_h } //= 20;
# more logic if needed..
return %conf;
}
So the fourth option for me
HtH

Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.

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.
