How to build a conditional steps using ogre

[Fairuz WAN ISMAIL]

Hi,

I'm having trouble building a conditional query. 

I'm hoping to have something like 

(oq/query 

   (tv/find-by-kv tx :label "Restaurant")

   (if-not (nil? FOO) 

        (oq/--> [:featured-in])

        (oq/has :name "RESTOFTHEMONTH"))

   oq/into-list!)

Is it possible to achieve this kind of query? Thanks

query is just a glorified ->, try using cond-> or ?> from https://github.com/Prismatic/plumbing or factor it out to a seperate fn. 

If you need branching based on where you are in your pipeline, Gremlin has ifThenElse [http://gremlindocs.com/#branch/ifthenelse], but it doesn't seem to be implemented yet in Ogre (but it shouldn't be too dificult to write your own wrapper following the examples in Ogre source).

Oh thanks, I just realized it really is just a glorified ->. I end up adding an anonymous function in the chain.

Something like: ((fn [v] ...))

Thanks.
