Re: [rules-users] DSL to multiline DRL?
Newlines are ignored by the DRL parser.
You can pack any number of Conditional Expressions into the expansion
of a DSL phrase. Just make sure you put it all on a single line in
your DSL file:
# line 1
[when] There are mutliple transactions with the same value for
prodCat=$a : Trans( $groupValue : prodCat, $date : date ) not Trans(
this != $a, prodCat == $groupValue, date < $date ) $b : LinkedList(
size >= 1 ) from collect ( Trans( this != $a, prodCat == $groupValue,
date > $date ) )
# line 3

Is it possible to have a single line of DSL convert into multiple
lines of DRL?
I want to hide the implementation of my rules from the user. So, using
my previous post as an example:
rule "group 1"
when
$a : Trans( $groupValue : prodCat, $date : date )
not Trans( this != $a, prodCat == $groupValue, date < $date )
$b : LinkedList( size >= 1 ) from collect ( Trans( this != $a,
prodCat == $groupValue, date > $date ) )
then
//do something
end
should become something like:
rule "group 1"
when
There are mutliple transactions with the same value for prodCat
then
//do something
end
Thanks,
Tim
