Re: [Chicken-users] Cryptographic eggs
A new version of aes with the hexstring stuff stripped out, and a new crypto-tools egg with the hexstring stuff in *and* an implementation of CBC in are now in SVN. I'd like to add some other modes to the crypto-tools egg, such as HMAC stuff, as time permits. But, first, I'm going to go and add encryption support to Ugarit, the goal of this egg-writing arc!

Rather than manually specifying the % versions. These primitive inlines are mainly intended for use in the core libraries, where exact control over what is inlined and what not is crucial. These libraries can't be compiled in unsafe mode, but certain primitives can or must be coded with unsafe operations. cheers, felix ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

I don't have the time for participating, but I think this is cool idea. Note that mingw (with windows shell) and msvc is the real challenge (but a good target, because we can get around the shell limitations that way). cheers, felix ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

I had to set a few more things to get the program to display anything. Too bad I lost my modified SDL egg. Here's the initalization code I was using: (define (open-viewport width height) (initialize-video-mode width height 0 (+ SDL_OPENGL))) (define (initialize-video-mode width height bpp flags) (sdl-wm-set-caption "OpenGL Window" "OpenGL Window") (sdl-set-video-mode width height bpp flags) (sdl-gl-set-attribute SDL_GL_DOUBLEBUFFER 1) (sdl-gl-set-attribute SDL_GL_RED_SIZE 5) (sdl-gl-set-attribute SDL_GL_GREEN_SIZE 5) (sdl-gl-set-attribute SDL_GL_BLUE_SIZE 5) (sdl-gl-set-attribute SDL_GL_DEPTH_SIZE 16)) For some reason I still cannot understand, the program didn't work without setting those flags first. --Stephen programmer, n: A red eyed, mumbling mammal capable of conversing with inanimate monsters. > > cheers, > felix > > > ___ > Chicken-users mailing list > Chicken-users@nongnu.org > http://lists.nongnu.org/mailman/listinfo/chicken-users > ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] Scheme-based build system for Chicken
Dear all, Some time last December, I made a partial port of the Chicken build system to Scheme, and I got as far as getting Chicken 3 to build under Linux, Mac OS, and Mingw+msys. The code consists mainly of the PLT make macro, some FFI definitions to support I/O pipe functionality under both POSIX and Windows, and the ported make rules. I used the Chicken compiler to generate one C file which can then be distributed and used for boostrapping the Chicken build system. Even though the port is quite rudimentary, I think the result is a much more manageable build system, not in the least because it eliminates the ridiculous make scoping rules. Is anybody here interested in helping me continue work on this and porting it to Chicken 4? The current code is in the SVN repository, in directory release/3/cmk. Feedback and comments are much appreciated. -Ivan ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

Any idea when it'll be released? I'm looking forward to testing your "intarweb" egg, but I'll probably wait until Chicken 4 is released. thanks again d p.s. In my local version of the http egg, I replaced the definition of http:read-request-attributes with the slightly-modified rfc822-header->list procedure that I described in my previous email, and it's working fine, too. pgpsdMr7mrNRY.pgp Description: PGP signature ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
