First take a look at the gui libraries mentioned in the libs post. After that there is: http://www.franz.com/products/allegrocl/acl_gui_tools.lhtml http://www.lispworks.com/ http://www.ahklisp.com/ http://docs.plt-scheme.org/gui/index.html http://clojure.org/ -which can use java gui libraries using ...

Here's the beginning of a mini lisp practice project, connect 4. Feel free to chime in with code, critiques or other input. I would like to practice the coding approach of a dsl and simultaneous bottom up and top down, so to start here is some pseudo code: bottom up: (defun make-board () ) (defun pr...

How about clim, hunchentoot and cl-ncurses. That way one can create gui's for the desktop, web and cli.

Look at the levelnum code and think about how to change it.

The svg file format is an xml script. Just replace the words 'hello out there' with whatever words you want to display, and open it with any browser except internet explorer. http://www.w3.org/TR/SVG11/text.html Lisp related books in German: http://books.google.com/books?ei=QMX6SoHvGsmCnQfy7qiADQ&am...

Congratulations on a valiant attempt that is almost there. Here are some observations: CL-USER> (nivel '((a) b c) 0) ; Evaluation aborted. CL-USER> -returned 'b is not of type list' CL-USER> (nivel '((a) (b) (c)) 0) 1 CL-USER> -function requires all root level leaves to be lists. CL-USER> (nivel '((...

If your function is recursive, walking both the car and cdr parts of a list, and uses > to decide which depth number to return (such as to a + function), than it will work on n-ary trees. If you post the function you wrote, I'll post one I wrote and we can comment on it. Car is the first item in a l...

Here's another way to do it, create an svg image using something like this saved to an x.svg file, with the 'Hello out there' words replaced: (setf ss "<?xml version=\"1.0\" standalone=\"no\"?> <!DOCTYPE svg PUBLIC \"-//W3C//DTD SVG 1.1//EN\" \"http://www.w3.o...

If you know how to obtain a certain number using a certain form, why do you need to set a variable to it?

If needed, post whatever code you have so far and perhaps more hints will be forthcoming.

CL-USER> (eachlast '((1 9 5)(3 3 3)(1 0 3 0 2)))
(5 3 2)
