Hi everyone,
I have been struggling with this, hopefully, simple problem now for
quite sometime, What I want to do is:
*) read a file line by line
*) modify each line
*) write it back to a different file
This is a bit of sample code that reproduces the problem:
==========================================================
(def old-data (line-seq (reader "input.txt")))
(defn change-line
[i]
(str i " added stuff"))
(spit "output.txt" (map change-line old-data))
==========================================================
#cat "output.txt"
clojure.lang.LazySeq@58d844f8
Because I get the lazy sequence I think I have to force the execution?
but where
exactly? And how?
Thanks in advance!!!
Thomas
