makelisp 是 GNU make 的 Lisp 实现。
makelisp.mk 是 GNU make 中的 Lisp 解析器。
GNU make 包含两个内置函数:$(shell) 和 $(guile)。

FizzBuzz:
$ cat fizzbuzz.l | make -f makelisp.mk (lambda (n) (if (eq n 101) nil (if (print (if (eq (mod n 15) 0) FizzBuzz (if (eq (mod n 5) 0) Buzz (if (eq (mod n 3) 0) Fizz n)))) (fizzbuzz (+ n 1)) nil))) PRINT: 1 PRINT: 2 PRINT: Fizz ... PRINT: 98 PRINT: Fizz PRINT: Buzz nil
Sort:
$ (cat sort.l && echo '(sort (quote (4 2 99 12 -4 -7)))') | make -f makelisp.mk ... (1 2 3 4 5 6 7) (-7 -4 2 4 12 99)
