Bad: (do-something first-argument second-argument (lambda (x) (frob x)) fourth-argument last-argument) Good: (do-something first-argument second-argument #'(lambda (x) (frob x)) fourth-argument last-argument) Spacing of ParenthesesĪlways space elements like this: (+ (1 2) 3) and never like this (+(1 2)3) or (+ ( 1 2 ) 3). However, do not insert newlines in a way that makes it hard to tell how many arguments the function takes or where an argument form starts and ends.

Distinguished (“special”) Arguments: Indented four spacesĮxamples Align arguments to a function with the first argument: (my-function arg-one arg-two arg-three) Or under the function name: (my-function arg-one arg-two arg-three) Body should be nested two spaces: (when something (do-this) (and-this) (and-also-this)) Distinguished forms should be nested four spaces: (with-slots (a b) distinguished-form (print a) (print b)) Line Spacing / Newlines.

In this article, we will discuss some basic concepts for formatting Lisp code and I will share with you my personal notes, as a professional designer of presentations and reports. As many experienced lisp programmers have pointed out, and as this article will hopefully show, properly indented code makes reading lisp much easier and the parentheses disappear into the background.

Lisp is infamous for its reliance on parentheses ( ) to delimit code and is notorious for being difficult to read because of this.
