your best bet currently is to write an eval and add it manually... at
least until we can local.cf our own evals, which i believe is coming
soon if i remember the discussion.
o.k... now a little off topic :)
what would really be nice, is to be able to return a score from an
eval... instead of just true/false and then scoring based on a "score
RULENAME" line.
that would prevent having to call an eval a dozen times with different
$min and $max values to determine what the score should be. i know most
evals return if $self->{eval_variable} exists, so it doesnt hamper
performance much if any when the same eval is called many times over....
i think the only big thing you loose doing something like that, is the
ability to see what rules fired, and the descriptions associated with
them.
maybe adding an extension onto it eval:function(), say
eval_score:function(), which makes a rule look like
body TEST_EVAL_SCORE eval_score:function_name()
describe TEST_EVAL_SCORE this is a test
score _TEST_EVAL_SCORE_
i'm not sure exactly how the score line would work, as score needs to be
substituted from the return value of function_name()... maybe storing
the return value into a tag like _HITS_, _YESNO_, etc, but instead it is
the _RULENAME_ ?? not sure if this is possible the way Conf.pm parses
the .cf's before eval's are ever ran.... but its a thought nontheless.
