Re: :Keywords and their use
Aaah I see. That second article explains it well
. However, how was I supposed to know that the keyword had to be :TEST?

:Keywords and their use
Hi all, I'm struggling to understand the use of keywords. I understand that keywords evaluate to themselves, thus :A is :A. But take the following code: (member '(c cat) '((b bird) (c cat) (d dog) (s squirrel))) If I were to run that, it would return NIL because member is using eql instead of equal ...

Re: Lisp practice fuction not returning what I expected
Thank you so much it works now! :D. I would probably never have guessed that was the problem. So if I use literals only one is stored in memory...hmmm. If I were to set a list to quote a (' a) then would the following diagram be roughly correct? [ | --]-->[ | --]-->[ |/] This is a list. |__________|...

Lisp practice fuction not returning what I expected
Hi all, I've written a function to rate games and return a list of the games with their rating, but I am having trouble getting it to return the list properly. It either returns the list with their ratings as 0 or as 1, never more like it should. I have worked on this function for a while now and no...

Re: Lisp Debugger
I downloaded LispWorks, but I have to say the program doesn't seem to have a very intuitive design
. I have no idea how to step through my code...Anyone know a step-by-step tutorial?

Lisp Debugger
Hi all,
I'm writing in Common Lisp and I need a debugger; one which can allow me to step through each line of code and see what it is returning. Is there such a debugger?

Re: Beginners Question - Can't manipulate a local variable
At the moment I'm just trying to get to grips with how Lisp works, before I start declaring classes and such.
It completely makes sense now after seeing the Java examples!!! In fact, I've gotten it to do what I want now
.
Btw I really appreciate all the help guys.

Re: Beginners Question - Can't manipulate a local variable
I tried changing the list's name to *game-list* but that didn't change the results, so I take it this is just common practice? So, at the moment Lisp thinks that I'm passing in a list and it should treat it as a local variable? How would I make it understand that I want it to change the global varia...

Re: Beginners Question - Can't manipulate a local variable
I said that my previous post was the last :lol:, but I seem to have come across something new which I can't explain. Taking the list that I provided in the previous post: (setf game-list '(((title "New Super Mario Bros. Wii") (genre "Platform") (platform "Wii") (price 2...
