http://www.clara-rules.org/docs/rules/ mentions "props", but I can't see documentation for them on that page. Does anyone know what they are?

@dominicm it is a simple map, currently the only thing supported would be salience, i think. http://www.clara-rules.org/docs/conflictsalience/

@dominicm @ethanc there is also :no-loop

However, it’s typically not recommended to write rules in a way where you have to use that

it can have confusing semantics I believe

(probably why it hasn’t been documented much 😛 )

Is it possible to create rules with parameters? And be explicit about passing them in?

@dominicm It isn’t clear to me how that would work in general

However, queries take parameters if that’s more what you’re looking for

For rules, instead of taking a parameter, model the param as a fact inserted by a rule perhaps

Instead of

(defrule param-rule
  [A (= <my-param-here> x)]
  =>
  <do things>)

(defrule find-param
  [?i <- InputFact]
  =>
  (insert! (map->Param (extract-data ?i))))

(defrule param-rule
  [?p <- Param]
  [A (= (:x ?p) x)]
  =>
  <do things>)

@mikerod hmm, maybe I haven't thought it through. But I want to write rules like "for every X insert 5", where I might have multiple of these inserted.

Ah, right, of course.

My rule just needs to find "Candidate X", and then insertions can be made about X candidate. 🙂

I think so
