Can somebody show me either a) examples where macros are desperatly needed b) some patterns where macros are used c) explain how to build an embedded language on top of lisp like I heard so many times Example 1 : Ever heard of Paul Graham new language Arc. It has a very nice conditional operator th...

What Slobodan said: Hunchentoot unless you're using ACL, and possibly even then. Edi code is good but I doubt that general purpose server could beat Aserve on dedicated implementation with commercial backing. Two more suggestions that I didn't tried myself: Anti web http://hoytech.com/antiweb/ I ha...

AllegroServe if you are ACL user, hunchentoot for everything else.

VECTOR-PUSH-EXTEND is what you want but array must be adjustable. http://www.lispworks.com/documentation/HyperSpec/Body/f_vec_ps.htm Arrays are continuous blocks of memory I really doubt you will gain much if at all by using simple array especially in accesing elements. Maybe it would be better if y...

Yeea! Solved. Nice working. Code: Select all (defun add (number) (intern (format nil "*~a" number))) (defun myfunc (x) (cond ((null x) nil) ((< (car x) 0) (cons (add (car x)) (myfunc (cdr x)))) (T (cons (car x) (myfunc (cdr x)))))) Thanks Now the question can lisp differ even and odd numb...

Do you need something like below?

(defun foo (l high low)
(mapcar #'(lambda (e) (and (> e low) (< e high))) l))
FOO

(foo '(4 7 2) 7 3)
(T NIL NIL)

If you want string representation: (concatenate 'string (princ-to-string (random 3)) (princ-to-string (random 3)) (princ-to-string (random 3))) ->"112" Else I don't know how to present for example 012 as number as starting zeros will be removed. 012 ->12 bobi http://www.linkedin.com/pub/di...

As I'm doing essentially the same, I can say it would be very great to have such a beast ready off-the-shelf! Just please beware of UCW/Weblocks plague: if you release something, make its examples work straight out of .tar.gz, and make them easy to adapt. I wrote about hackbraries (*) and there was...

It might be better to decide which language do you want to learn first common lisp or scheme, going through both of them in a same time would only confuse you. If you decide to fallow the common lisp way Practical common lisp is a great book though for a complete beginner to programming Gentle intro...
