Question

I am new to clojure and the main thing I am struggling with is writing readable code. I often end up with functions like the one below.

(fn rep 
  ([lst n]
    (rep (rest lst)
    n
    (take n 
      (repeat (first lst)))))
  ([lst n out]
    (if
      (empty? lst)
      out
      (rep 
        (rest lst) n
        (concat out (take n 
          (repeat 
            (first lst))))))))

with lots of build ups of end brackets. What are the best ways of reducing this or formatting it in a way that makes it easier to spot missing brackets?

Answer 1

An editor that colors the parenthesis is extremely helpful in this case. For example, here’s what your code looks in my vim editor (using vimclojure):

Since you didn’t say which editor you use, you’ll have to find the rainbow-coloring feature for your editor appropriately.
