Re: What is best practice regarding transducers
If you have a public project on Github that is using transducers, would you please point me to it? I would like to see what you did. Fipp's Clojure 1.7 tuned-up engine uses transducers to emulate mapcat(-with-state), while minimizing intermediate object allocations. Reducers was used previously, but mapcat still required intermediate allocations. Transducers avoid that, but take on a more effectful feel. Code here: https://github.com/brandonbloom/fipp/blob/648d928d94f0b247af9a0c4f95e7ec7024b5b001/src/fipp/engine.cljc -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: What is best practice regarding transducers
xempty is a transducer that just returns an empty result, essentially ignoring the input. The thought was that a degenerate transducer might be useful in a complex chain if you want to stop processing. I haven’t actually used it for anything, just experimenting.

Re: What is best practice regarding transducers
I used transducers here https://github.com/raspasov/neversleep/blob/master/src/neversleep_db/node_keeper.clj Look at all the functions ending in -xf, they return transducers that are being attached to core.async channels.
