Dear Community,
I have one question about readability. As I am not yet deep into
Clojure I can only post scala but I am sure you will get my point.
Recently I wrote the following dump function in Scala:
// convert 1228 to "e2e4"
def move2ascii(move: Int): String = { // Clojure Style
(((move / 100) % 8 + 97).toChar).toString + ((move / 100) / 8 +
1).toString +
(((move % 100) % 8 + 97).toChar).toString + ((move %
100) / 8 + 1).toString
}
but I could as well have written it like this in an imprative style:
(both are equal)
def move2ascii(move: Int): String = { // Scala Style
val f1 = move / 100
val f2 = move % 100
val row1 = f1 / 8 + 1 // 2 von e2
val row2 = f2 / 8 + 1 // 4 von e4
val col1 = (f1 % 8 + 97).toChar // 5 = e von e2
val col2 = (f2 % 8 + 97).toChar // 5 = e von e4
col1.toString + row1.toString + col2.toString + row2.toString
}
I am sure if you write the first function in Clojure it would look
nearly the same.
My point and my question is:
Isn't the second function easier to read? I know there had been a lot
of threads about readability
in clojure but I am not yet convinced.
In the second version the brain can rely on some steps inbetween which
make it more readable
for me. Or should the first function be split up into several more
functions to become more readable?
I would be happy if you convince me to give Clojure a better chance.
Thanks in advance

P.S.: It's nice to see the upcoming Clojure book in Manning!
