Show HN: YakshaLisp – Macros for Yaksha and Lisp Dialect https://bit.ly/3OCITEb

Show HN: YakshaLisp – Macros for Yaksha and Lisp Dialect YakshaLisp is a sub-language embedded in Yaksha compiler. Allowing you to do things like below (fizzbuzz). macros!{ (defun to_fb (n) (+ (if (== n 1) "" " ") (cond ((== 0 (modulo n 15)) "FizzBuzz") ((== 0 (modulo n 3)) "Fizz") ((== 0 (modulo n 5)) "Buzz") (true (to_string n)) ))) (defun fizzbuzz () (list (yk_create_token YK_TOKEN_STRING (reduce + (map to_fb (range 1 101)))))) (yk_register {dsl fizzbuzz fizzbuzz}) } def main() -> int: println(fizzbuzz!{}) return 0 This is available in latest release - https://bit.ly/3OAl1Rv (I recommend using release.py in compiler/scripts if you want to locally compile it) Few more examples: - embedding a text file macros! { (defun load_string (file) (list (yk_create_token YK_TOKEN_STRING (io_read_file (map_get file "value"))))) (yk_register {dsl load_string load_string}) } def main() -> int: println(load_string!{"test.txt"}) return 0 - importing a macro import import_me as magic def main() -> int: println(magic.counter!{}) println(magic.counter!{}) println(magic.counter!{}) return 0 Looking for ideas/advice/criticism :) https://bit.ly/3Ki5aUU July 31, 2023 at 12:00PM
