Once the library has been defined and loaded into the Lisp image, work can begin on defining C routines in Lisp.

Before that can be done, however, a note for those who do not know C... Read More...

One of the more significant difficulties I face when developing Lisp applications is the apparent lack of generally compatable database libraries for the various lisp dialects. CLSQL is a nice solution, but it does not get along well on OSX, my development OS, or with CLISP, which is the primary lisp dialect I have available on my host...

Using CFFI, we can fairly easily create mappings for the most important MySQL C api functions. This entry will walk through the process of importing the library; future entries will go one to defining a few of the most basic routines for our lisp image. Read More...

Paul Graham notes that, "A popular recipe for new programming languages in the past 20 years has been to take the C model of computing and add to it, piecemeal, parts taken from the Lisp model, like runtime typing and garbage collection." This is what has made Python such a wonderful, elegant, and concise language. Why say with iteration what can be done in one easily readable line with a list comprehension? Read More...

A common point of confusion for lisp beginners is the macro. Few lispers can resist the opportunity to expound the beauty and elegance of the macro. However, as with many lisp concepts, most explanations are outside the range of the hobbyist's experience. Read More...

When I first set out to learn lisp, I was faced with an intimidating number of choices. Which implementation of lisp should I choose? Common lisp? Scheme? I went with common lisp. Which common lisp? SBCL? MCL? Gnu clisp? Yeesh. This is enough to scare most lisp rookies off. Here is some advice: start off with Gnu clisp. It's available for most architectures, it's free, it has decent documentation online, and it's easy to install. Read More...
