<old>when I geiser-eval-buffer inside a R6RS libray, I get the following error: unknown location: definition in expression context, where definitions are not allowed, in form (define (fuz) #t) <old>any idea? I've never used the R6RS form before <old>Odly I get the same thing trying to compile with compile-wasm <sneek>I've been a process for one month and 20 days <sneek>This system has been up 11 weeks, 13 hours, 2 minutes <euouae>Hello, in SDL2, there's SDL_AddEventWatch taking a callback <euouae>how can I use this function from Guile? Can Guile generate callbacks on the fly? <euouae>e.g. if I wanted to pass a Guile lambda to it <euouae>Looks like I need to write my own C procedure that converts Scheme source into a C function pointer <old>euouae: Are you call SDL_AddEventWatch from C or from Guile FFI bindings? <old>for the former: Use procedure->pointer in (use-modules (system foreign)) <old>However, you need to keep the procedure passed to procedure->pointer somewhere. Otherwise the GC will bite you <euouae>I want to dynamically load SDL_AddEventWatch and call it with an argument from Guile <euouae>I was worried I'd have to do something ugly... <old>it is important to keep the scheme lambda somewhere. The GC won't protect it because the pointer object passed to C does not keep a reference back to it <euouae>that project does not support SDL_AddEventWatch old <euouae>It's what I was looking at. I was wondering how to add it in. <euouae>btw I found a tiny wee lil bug in the doc page for procedure->pointer so we've successfully collaborated on fixing a bug today <euouae>dang you whipped up that code real fast <euouae>old: isn't it better to use guardians? (make-guardian) <euouae>oh, the issue being order. nevermind <euouae>old: just a nitpick, you'd probably want to sdl2-delete-event-watch and then hash-remove! <lechner>Hi, is Guile expected to work flawlessly in a fully sanitized, zero environment? <lechner>Hi, I think I have old duplicates in my GUILE_LOAD_PATH. Is there a way to show, from the runtime, the file paths of the modules that have been loaded? <old>lechner: like what path module M is from? <cow_2001>dthompson: (make-websocket "wss://andre.su") fails here :< <cow_2001>In procedure getaddrinfo: Servname not supported for ai_socktype <robjperez>cow_2001, out of curiosity I gave the websocket lib a try. It says I don't have gnutls module available. I'm pretty new to guile ecosystem, so I'm not sure what to do <robjperez>saw that there is a fedora pacakge called guile-gnutls, but after installing it, i get the same error <old>sneek: later tell euouae you are right. The callback needs to be removed from SDL before removing the reference in Guile <graywolf>Hm, how can I change the encoding for regexp-exec? I've tried (with-fluids ((%default-port-encoding ... but I am still getting "cannot convert narrow string to output locale" error. Any ideas? <graywolf>My reading of the documentation is that is does not seem to be possible, but maybe I missed something...
