Where is an input-output stream
I mean a stream you can write to, and when you read from it, the same comes out. Basically as in the example make-two-way-stream , but with less angering me by showing it can be done but only giving an horribly crappy way. Basically i want a function that makes `(make-two-way-stream (make-string-inp...

new language; Julia
Searched for the word in the forum, did not find it. So i thought i'd post about it. This was their 'introductionary blog post , you may have seen it from other places. Basically Julia is a lisp, if you look at metaprogramming for a description. Basically, code afaics consists of Expr objects. It ta...

Re: Date operation
Why not just decode-universal-time and encode-universal-time?

Re: Destructive function on constant data
Afaik QUOTE does not make x constant, quote make the variable x point to a list '(1 2 3 4 5), but that list is *not* created when you call it, it is always there. So if you do: (defun quote-abuse () (let ((list '(1 2 3 4 5))) list)) (setf (car (quote-abuse)) 'unexpected) (quote-abuse) ;=> (unexpecte...

Re: 2D graphics/turtle lib suitable for kids?
cl-cairo2 ( github ) would be good for it especially if we also could easily have keyboard/mouse/etc input in conjunction with it, and it has much more drawing ability. Neat to be able to export to many things, svg, ps, pdf, png, X11 window. Maybe i'll see if i can add a function to give sdl an cai...

Re: can u help me to solve this ...plzzz
You could make (defgeneric coin-value (coin) (:method ((coin (eql 'dollar)) 100) (:method ((coin (eql 'dime)) 10)) ;..Etcetera, just a way to list values of the different types. And then you feed the function a list, starting with the higher-value coins ending with the lower value coins, and then go...

Re: How to convert list element to string type
Best way to figure it out is to try it in this case :) CL->USER> (read-line) yup it is a string "yup it is a string" nil You can coerce a string to a list with (coerce string 'list), but that'd be a list of characters, of course. I think you might want to use READ which reads one s-express...

Re: Lisp functions and very new to lisp
Not sure where to find an 'accounting example' tutorial, if you mean that. There are a couple of good books, like Practical Common Lisp . this thread lists a bunch of other books, though not all as suitable. You could, for instance, make what you say with hashtables(make-hash-table,gethash) and stru...

Re: What's your favorite book about Lisp?
