As reading the documentation would reveal, the toplevel function is not supposed to return, but your does, and the system is getting confused. I am not sure why it is so, but your code should be: (defun hello() (format t "Hello, (cruel) world!~%")) (sb-ext:quit)) And as for the kitten of d...

...with the libraries available in the CL community (i.e. ASDF-installable)... FIrst, there isn't such a thing as "CL community", which might be a part of the problem... there are several scattered weakly connected communities centred around various communication channels, ie. people here...

I don't know much about sockets, especially in CLISP, but looking at http://www.lispworks.com/documentation/ ... finish.htm maybe force-output rather than finish-output would help?

Well, I wouldn't call it Evil, but not exactly close to Good, either. Personally, I prefer more functional approach of using compose/curry/rcurry functions, from, say Alexandria , misnamed as they are. They allow me to avoid explicit lambda in simple cases, and for more complex case I think it is be...

A "fas" file is really called a fasl file, where fasl is a shortened form of "FASt Load". Those files are supposed to be loaded into a Lisp image, containing among other things a runtime. It is possible for it to execute code which actually performs actions, but most often it wil...

cl-magick is a very thin wrapper around imagemagick, which means that to use it you have to refer to ImageMagick documentation . I have used it very briefly some time ago, so I don't remember much, but I think resizing an image would go something like that: (defun resize (file out-file w h) (let ((w...

As far as I am aware, this is outright impossible, because SBCL memory model has to many assumptions about owning the process or somesuch... But I never looked into SBCL internals. Still, I have never seen any mention of that, and usually for embedding an open-source Lisp ECL is recommended.

Side effecting read macros are a bad idea. There is no guarantee that they will be executed once when expanding, and in general run into weird issues like the one you have here. What I would do if trying something like this is to make the read macro expand to some unexported symbol, and then walk th...

1) Should I really learn Lisp? Or should I get on with C? Well, what answers do you really expect on a LispForum? But really, it depends what you want from a programming language. Common Lisp is a great, but if you care more about some C-specific functionality (like low-level interaction with the O...

I have another related question. Since macros don't evaluate their arguments, is there a way to get an argument to a macro to evaluate without using eval ? The point of macros is that they happen at compile time, so all necessary information must be available at that time. If such information doesn...
