Lithp

This is a toy interpreter for a Lisp-like language. It's currently a work in progress (and at a very early stage) and will probably never become production ready.

At the moment it can execute programs like the one shown below.

Example Program

(def finput 10)

(func factorial (params n)
  (if (= n 0)
      (return 1)
      (return (* n (call factorial((- n 1))))) 
    ) 
)

(func countdown(params from to)
(
    (print from)
    (if (> from to) 
        (call countdown((- from 1) to)))

    (print (concat "Unwinding..." from))
))

(print (concat "The factorial of " finput " is " (call factorial(finput))))
(call countdown(5 1))

Output

The factorial of 10 is 3628800
5
4
3

1
Unwinding...1
Unwinding...2
Unwinding...3
Unwinding...4
