Hi all,
I am a Clojure beginner ....
And I have an advice to ask !
I have an array of events:
(def events [
{:id "1" :duration 100}
{:id "2" :duration 200}
{:id "3" :duration 300}
])
I wanted to transform this array into:
[
{:id 1, :duration 100, :time 0} ; event 1 starts at 0
{:id 2, :duration 200, :time 100} ; event 2 starts when event 1 is
finished, so at 100
{:id 3, :duration 300, :time 300} ; event 3 starts when event 2 is
finished, so at 100 + 200
]
Here is the function code:
(defn to-timed-events
([time events] (to-timed-events time [] events))
([time timed-events events]
(if (empty? events)
timed-events
(let [current (first events)
next-time (+ (:duration current) time)]
(recur next-time (conj timed-events (assoc current :time time))
(rest events))
))))
It seems to work, but it looks a bit long for what it is doing. Is it
possible to improve it ?
Thanks for your help,
Olivier
