Longino CL + matrix/vector math

General Discussions
#1

Hey, this is my project: http://www.longino.com.br . For now it is an implementation of Common Lisp using the scripting API.

I haven’t uploaded the code I am using to call opengl functions, but the interface is the same as described in the website for interacting with Java. In other words, it is just a matter of generating the functions via a macro.

It supports closures and all. But the most cool feature are macros, like functions that are evaluated before runtime. For example:

(defmacro degrees (radians)
(* radians (/ 180.0d0 pi)))

This will be expanded during compilation so it won’t take any time during execution. This allows for generating arbitrary sequence of instructions based on a tree structure (macros nested parameter lists = tree).

Remember, these macros work at a representation level, processing trees of data and returning trees. The difference between this and the C pre-processor is like between day and night.

#2

Hi, I just uploaded a new version, 0.9.1. The new features include matrix and vector math. Matrices and vectors are now native types, which means that calculations are done using Java primitive types.

Here is the article describing it: http://www.longino.com.br/article.html?file=matrices

New version out.

Also, created a twitter account for announcing new versions and stuff on the site. The link is on the home page.
