I'd suggest wrapping the code that writes via prn to the file with a
dynamic binding:

e.g. at a REPL:

user=> (set! *print-length* 5)
5
user=> (prn (range 10))
(0 1 2 3 4 ...)
nil
user=> (binding [*print-length* nil] (prn (range 11)))
(0 1 2 3 4 5 6 7 8 9 10)
nil
user=> (prn (range 10))
(0 1 2 3 4 ...)

If you don't know how this works (or differs to lexical binding via let)
you can read up on vars here:

https://clojure.org/reference/vars

Hope this helps!
