There are other possibilities, you can write a macro which would cover the combinations or create your own subclass of generic-function * which would deal with the arguments by sorting of those or whatever. I'd like just to point out another angle of view. * With the help of MOP and closer-mop is th...

Well, don't avoid anything, you'll just use it anyway in a limited way (as "singlemethods") most of the time so let yourself make a decision later on (per project/module). The thing is that Java implements OOP in its own way and from it follows that there are Java specific design patterns,...

You are looking for describe-object.

Well, look at this wiki page to differentiate the Java methods and CLOS methods. And look at this manifestation of CLOS flexibility.

That can be simplified to: (defun symbol-from-items (&rest items) (intern (format nil "~:@(~{~a~^-~}~)" items))) (symbol-from-items 1 2 3 'hello "kitty") => 1-2-3-HELLO-KITTY I've created an read-time template library and with that it should be straightforward to do this symb...

Well, back in the day I was using: (asdf:oos 'asdf:load-op :system) ;or (asdf:operate 'asdf:load-op :system) because of this site (I'm going to fix that and add the load-system option). When I was writing that gist I didn't like the tardiness of writing the aferomentioned asdf part and used require ...

You can load Quicklisp by yourself and then load the given library: ;;; The following lines added by ql:add-to-init-file: #-quicklisp (let ((quicklisp-init (merge-pathnames "qkcl/setup.lisp" (user-homedir-pathname)))) (when (probe-file quicklisp-init) (load quicklisp-init))) Looking to my ...

By the description section in CLHS you apply 2nd and 3rd rules. [2] (nconc nil . lists) == (nconc . lists) [3] (nconc list) => list For your first code you apply the 3rd rule and The last list may be any object . That's: (nconc 1) => 1 For your second code you apply the 2nd rule then the 3rd one: (n...

There is another possibility: using a single hash-table and a multidimensional key. Having string keys, the default eql test is probably insufficient, you'd like to upgrade test function to equal and then you can reasonably use cons pairs as key as well. Or write own test function tailored to your k...

I can't tell, I've only used CommonQt. But after one brief glimpse, the CAPI is lacking native dialogs (eg. file chooser) and simple-tk has it.
