Hi all,
Is it possible to use a constant for salience instead of hardcoded
value? It have a sence when you have many rules and only several
salience level. They maybe more descriptive like START, VALIDATION,
etc and easier to maintain in the future. If it not possible right
now, then maybe it worth to request like feature request in the
future?
3:20 a.m.
One way to achieve this (with a little extra effort) would be to use a
DSL where you define START etc. as keywords with an expansion
to "salience 100" etc.

New subject: Using constant for salience instead of hardcoded values?
Salience can be defined using expressions - so have you tried it?
If referencing a static constant (perhaps in a java class) doesn't work you could try
a global,
if that doesn't work try defining a function call which returns the desired value, if
that doesn't work you could add an extra fact containing the value, bind the value to
the variable and then use that variable for the salience.
Once you've tried it let us know which ways do/don't work!

You can use:
- a fully qualified public static field, e.g. salience (
(int)java.lang.Math.PI )
- a DRL-defined function, e.g. function int FOO(){ return 10; } ...
salience( FOO() )
- a global, e.g. global Integer foo; ... salience ( foo ). But
initialisation is clumsy and not checked by a compiler.
- any field from any fact.
You can NOT use a static field imported with a "start" pathname, e.g.,
import function com.acme.*.
