printf does not always generate output

[Cecil Westerhof]

My core.clj ends with:
    (println (format "Started: %s (println)" (java.util.Date.)))
    (printf "Started: %s (printf)\n" (java.util.Date.))

I do not see the output from the printf when I run 'lein repl'.

The funny thing is that when I switch the two statements, both are shown.

Also when I do 'lein run' both are shown.

What could be happening here?

For the moment I changed all my printf to println with format, but it is a little annoying.

Try adding (flush) at the end.

Not every function and macro is documented completely or accurately on ClojureDocs.org, but I would recommend checking it out when you run across something that looks amiss, and see if the examples mention what you are seeing.  In this case, it does:

​That is certainly a place I should look more often. :-) A wealth of information.

I have https://jafingerhut.github.io/cheatsheet/grimoire/cheatsheet-tiptip-cdocs-summary.html bookmarked and also like basically always open in a tab forever, fwiw.
