Re: To learn or not to learn, that is the question

To play devil's advocate I thought I'd post this:
http://codangaems.blogspot.com/2008/06/ ... -lisp.html

It is a high level critique of Lisp by someone who likes Lisp a lot so I think it is fair to say it is quite objective.

Re: Graphical Programming in Lisp?

I've been thinking a lot about a graphical program editor for Lisp, for which it would be especially well suited because of its strict tree structure. I don't know if you've seen this http://en.wikipedia.org/wiki/Visual_programming_language or more specifically this http://en.wikipedia.org/wiki/Open...

Re: Accessing parent objects in CLOS

If I do decide to make a reference to the game object in the ball object, how would one do this? Without a concept like this like you would have in Java *shudder* how would you pass a reference to a parent object to a child object when you haven't finished instantiating the parent object? Use a fact...

Re: Accessing parent objects in CLOS

Cheers.

Is this the accepted way or should I ideally be changing my architecture so I don't run into this problem too often?

Perhaps I should get cracking on AMOP?

Accessing parent objects in CLOS

I was wondering what is the best way to access the parent of an object. Is there a way to access the parent through the child object? For example, imagine a simple game where by if a ball is in a certain position (eg the goal) a goal is scored and the score for that game is updated. Imagine also tha...

Re: Packages

How perceptive! Yes I think I do mean ASDF systems. How should one refer to something like, for example: lispbuilder-sdl? Is it a package, is it an ASDF system? Both? EDIT: I found this which helps a great deal http://weitz.de/packages.html If anyone could post some code where semantics of these ter...

Packages

I've been tinkering with Lisp for a while now. I've read through 3 Lisp books. One thing that I still don't have pegged is how to use packages correctly. I still find myself having to load packages manually. I was wondering if someone could provide an example of some code that demonstrates good prog...

Re: LispForum topic structure

I wouldn't worry about the topic structure. It is slightly unusual but thats probably due to Lisp's unusual nature not your taxonomy skills.
