Dear cafes

I use Conduit to parse a huge file. And I need merge lines by condition.

I find the concatMapAccumC can do that and I write a demo as blow(with conduit-combinators-1.0.6,lts-6.18).
The problem is if the last item didn’t make condition true, the data only keep in the accum but missing in stream.

Any one can give me some advises?

Thanks


----------------------------
import Conduit

test'::Int->Int->(Int,[Int])
test' a s = case (a+s) > 5 of
    True -> (0,[a+s])
    False -> (a+s,[])

testlog::IO [Int]
testlog = runConduit $ (yieldMany [1,2,3,4,5,6,3]) $=  (concatMapAccumC test' 0 ) $$ sinkList
