What about CLISP?
CLISP is another Common Lisp implementation that might be usable as a scripting system for WolkenWelten, since it uses bytecode it should be quite portable, although it seems that porting it to WASM is a bit tricky due to it doing some low-level stack Manipulation that is not possible on WASM (haven't looked at the code directly, but found a thread on reddit).
(defun messung ()
(let ((ret 0))
(dotimes (i 10000000)
;(incf ret i)) - Not sure why but this is A LOT slower on ECL, while on CLISP it seems a tiny bit faster
(incf ret i))
ret))
(defun main ()
(format T "~a~%" (messung))
(quit))
(setf *compile-verbose* nil)
(compile 'messung)
(main)
This completes in ~0.8s on my laptop, quite snappy. Just be sure to run with -norc since loading quicklisp does slow down
the start up considerably.
Pro
- Batteries included, additionally a lot of CL libs should just work and could be included by default
- Quite fast (test program is almost twice as fast as when interpreted by ECL, making it faster than CPython)
Contra
- No continuations
- ??? Emscripten/WASM support, might be possible to do but so far haven't found an Emscripten build.
- Very Slow Startup
- Doesn't seem to be very embeddable
- Last Release is 12 Years old? Doesn't seem to get much attention these days.
