SBCL is my implementation of choice. I had a hard time choosing #2. I almost always use SBCL on Linux, and I use it from time-to-time on Windows too, so I don't end up using CLISP as much as I have done in the past. My #2 is the LispWorks (Personal Edition), because it provides a great environment f...

WALKER is created in ARNESI, so its SYMBOL-PACKAGE is ARNESI. Because when you inherit a symbol it is the same symbol its SYMBOL-PACKAGE doesn't change.

If you really want to do this you could use read time conditionals then push the appropriate symbol onto *features* before recompiling. Downside is that you would need to modify any existing code you have to add in the read time conditionals.

For making GUIs, there are a number of binding to GTK (see this Cliki page; I think some of them should work on Windows).

There are other toolkits (Ltk uses Tk; I'd guess it would work on windows)

LispWorks (commercial implementation) provides CAPI which is cross-platform.

(FORMAT NIL "~r" some-integer) because it was the first time I've seen some of those words.

ED would be really cool if more implementations provided a resident editor.

Why not something like

Assuming you have copied the appendf code from DEFINE-MODIFY-MACRO's CLHS page, could you post the code for finden? Does finden contain the code that is trying to FUNCALL appendf?

I will learn Lisp. What annoys me most is the fact that there are so many implementations and they all have many differences, but I will just find my way around it. It makes one antisocial, but it works. Lisp: just works =) I think Lisp is what I will learn and that C will be what I will pursue whe...

or, a little neater (defun price-order-total (item-list) (loop for item in item-list summing (destructuring-bind (item quantity unit-price) item (* quantity unit-price)))) Or even neater: (defun price-order-total (item-list) (loop for (item quantity price) in item-list sum (* quantity price)))

I personally prefer sbcl over lispworks, mainly for the reason that it can use the package :arnesi (code walker), while lispworks can't. HOwever, it's not exactly 'easy to get into, atleast for win32, because you have to compile it yourself. Now, if you know how to compile programs, i guess its no ...
