I am trying to do some FFI to Raylib just to test the water, but I immediately get a floating point invalid operation error. I did not do any floating point operation, so I can only guess that SBCL traps something from the underlying library. This is all the code I have: (load-shared-object "../vendor/raylib/build/raylib/libraylib.dylib") (define-alien-routine ("InitWindow" init-window) void (width int :in) (height int :in) (title c-string :in)) (define-alien-routine ("CloseWindow" close-window) void) Yeah it's Mac OS, so to test this you need to change the shared object path. Don't use Sl ..read more

As many here know, David Botton is working hard on CLOG and his efforts are impressive to say the least. It would be great to see his 20 sponsor goal made as he is tirelessly working on dev journals and making excellent progress. Even for $2 it will help. https://github.com/sponsors/rabbibotton I have no affiliation with mr Botton, besides that I find the work he does awe inspiring. If you don’t know CLOG, try it out today: it’s easy if you run emacs and sbcl and it’s impressive for a one person operation. submitted by /u/tluyben2 [visit reddit] [comments ..read more

Sorry for a noob question. My first definition for function add: ``` (defun add (arg1 arg2) (+ arg1 arg2)) (defun main () (add 2 2)) ``` Now I changed the add function to accept three arguments. I recompiled the function. Now I want the sbcl compiler to issue warning regarding the number of arguments mismatch inside main function. submitted by /u/No-Check7471 [visit reddit] [comments ..read more

Is there a formal definition of it? I tried looking at the hyperspec but it seems like it only rigorously covers unnested backquotes, because the algorithm they give states that ``(,,x) = `(backquote ,,x) should become (append (list `backquote) (list ,x)) = (append (list 'backquote) (list ,x)) = (backquote ??). I don't understand what ,x is formally. Is it syntactic sugar for something like (unquote x)? In that case, why does (unquote x) evaluate to (unquote (eval x))? submitted by /u/Playful-Quarter-3108 [visit reddit] [comments ..read more
