Re: Yet another Lisp related screencast

This basically defines a new setf expander . You might want to look up defun, defsetf and the like in the CL HyperSpec for a more detailed unterstanding. However, in the case of the matrix it allows an aref-like access of the matrices elements both for reading and writing. Thank you very much for t...

Wait, I can do that?
August the newb here...what does this do? I did a macroexpand-1 and compared it to a regular defun but still don't get it :oops:

Re: The library situation (warning: mini-rant)

Ah. In that case, it looks like we'd get most mileage out of a more complete (in both senses) set of libraries to address things that have become much more common in the last 10 years or so, and making it easier to install and use them. Mostly, I suspect, polish (which is the other 90% of the devel...

Re: The library situation (warning: mini-rant)

If you're willing to pay for a GUI toolkit, there's one from Lispworks (http://www.lispworks.com/products/capi.html) and another from Franz (http://www.franz.com/products/allegrocl/acl_gui_tools.lhtml). While the open-source toolkits might have some way to go before they're newb-friendly, it's not ...

Re: The library situation (warning: mini-rant)

It's a plain ordinary chicken-and-egg problem: without a large user/developer community, there aren't enough people writing and maintaining libraries; without lots of good libraries, we can't attract the users. It's as simple as that. I think we need to be a little careful when we tell newcomers "i...

Re: What feature would you most like to see in Lisp?

For the OpenGL, the library at http://common-lisp.net/project/cl-opengl/ might help. Not sure how up to date it is, but it was committed to a week ago, so hopefully it is. For executable compilation, check this recent topic on compiling to an "exe". There are a few snippets for each implementation ...

Hello everyone, Just so you know where I'm coming from, my company develops computer graphics tools for the special effects and computer game industries. We use C++, but it's like driving around in first gear all day...there's got to be a better way :-) I am presently working through SICP and Practi...
