Re: macro expansion within macro

Macro forms are expanded only at places where a function call may be placed. Since (COND (COND-CLAUSE (= C 8) 1)) didn't work if COND-CLAUSE was a function it also doesn't work if its a macro. That is not really the problem. The problem in this case is that the interpreter/compiler macroexpands CON...

Re: Hello Lispers :)

Wellcome, kmruiz :)

If you are looking for Lisp projects, common-lisp.net and cl-user are full of them. Github has a lot of (mostly small) Lisp projects.

Fell free to hang around ;)

Re: Lisping in style

Is an ELT access O(1) on an array? Yes. Is AREF faster than ELT? If not, why would you use it? It depends on the compiler. If the compiler knows that the sequence is a vector, it can substitute ELT with AREF. Some compilers can infer the type of the object (e.g. SBCL) depending on the code around i...

Re: Lisping in style

Well, sorry for not seeing your code before, I didn't have time to answer your question. There are few things that I can comment on. If your intention is only to work with lists, then using ELT is not quite the best idea. As a general rule, it's more convenient to access the elements in a row (e.g. ...

Re: Why don't my solutions work? Specifics inside.

You need to check whether the argument X given is NIL, in which case you should return NIL.

Re: Structs in arrays

Code: Select all

(button-x (aref your-vector position))
or

Code: Select all

(slot-value (aref your-vector position) 'x)
(BTW, Common Lisp is case-insensitive, so 'X' and 'x' refer to the same symbol.
