If you’re interested in trying out Lisp programming, you might wonder how you can find libraries for useful functions. Maybe you want to try your hand at some Mandelbrot set generation, but don’t want to have to figure out how to write out the graphical files for viewing. Perhaps you want to do something with networking.
The starting point I’d recommend is the common lisp wiki at www.cliki.net. There, you can find links to working libraries that perform many useful duties, and let you concentrate on the code you’re trying to write. For instance, under graphics libraries, you will find about 70 entries ranging from PNG/JPG output to the Cairo API, to OpenGL linkages. Chances are you’ll find what you need for your project there, and if not, there are other possibilities, as we’ll see later, when I talk about CFFI.
