Incremental Output

[ben-denham]

Is there currently a way to incrementally update a cell's output? E.g. to provide a progress bar for some long-running background thread?

The closest I've come so far is the following snippet, which immediately prints "Let the above loop run in the background", but any calls to display after the cell has finished its initial output seem to be buffered until the next time the cell is executed:

(require '[clojupyter.misc.display :refer [display]])
(future
    (doseq [i (range 10)]
        (Thread/sleep (* i 100))
        (display (str "Completed " i))))
(println "Let the above loop run in the background")

Also, thanks for the super useful kernel!

Have you tried println?

It is indeed possible to incrementally update a cell, as in

(doseq [i (range 10)]
    (println i)
    (Thread/sleep 500))
:ok

which will print numbers 0-9 and finally return :ok as the result of evaluation.
