Subject: [cl-opengl-devel] checker.lisp (Redbook example)
Message-ID: <20081002110453.j1xt20m6jo8sswcs@webmail.hostberbee.com>

Well, I was already working on porting the redbook examples to Lisp (at 
least the ones that hadn't been done yet). And as Luis pointed out, 
doing that is on the list. So here's the first one, ported from 
checker.c. It's a texture-mapping example. I have some others that need 
cleaning up, because prior to updating my stuff, I had to do things 
like code-char key in keyboard, because that's just how it worked on 
the Mac. I have noticed that some of the redbook examples can't 
currently be ported, because cl-opengl doesn't offer all the functions 
yet. 

I wasn't able to use '(64 64) when creating the texture map, because I 
get this error:

* (load "checker.lisp")
; in: LAMBDA NIL
;     (SETF (AREF RET-VAL (+ BASE 1)) 255)
; --> SB-KERNEL:%ASET
; ==>

;
; note: deleting unreachable code

;     (SETF (AREF RET-VAL BASE) 255)
; ==>
;   (SB-KERNEL:%ASET RET-VAL BASE 255)
;
; caught WARNING:
;   Asserted type VECTOR conflicts with derived type
;   (VALUES (SIMPLE-ARRAY T (64 64)) &OPTIONAL). 
;   See also:

And I haven't included an update to examples.lisp -- it's just adding 
it to the list of examples, and examples doesn't actually run the 
examples unless you've already loaded them (I might work on that for 
the future).

I think I can better explain what I was asking now. I wasn't asking 
about what work to do, I was asking about how to go about making sure 
that work gets in where it's supposed to go. 

In some projects, one emails patches directly to the maintainer, who 
takes over from there. 

In some projects, one emails patches to the development list, and the 
maintainer takes it from there, but others might use rejected patches 
on their own. 

In some projects, everyone is given access to source control, and just 
throws stuff in (a rather wild and wooly version of development, but it 
exists). 

And that's aside from the process by which it's decided what paches go 
in or don't go in to official versions. Sometimes the maintainer 
decides, sometimes there's a committee, sometimes everyone just throws 
stuff in, etc. 

I'd like to 'play nice', but 'nice' means different things in different 
places. I'd like to know what 'nice' means for cl-opengl. 

For example, I've seen some patches submitted via this list, and I've 
seen you say 'thanks, I've put it in.'

I've done some work on one of the items suggested (that being Redbook 
examples), and I'd like to see them get put into the 'official' stuff 
(realizing, of course, that cl-opengl doesn't really have releases). 
That's why I posted checker.lisp to the list. So how do I go about 
getting into the darcs repository in a way that will keep everyone 
happy with me?

Yes, I've used a lot of text here, but the answer I got before (while 
useful) didn't answer the question I was asking. I hope that this is 
clearer.

One of us (lately it's been mostly just me) will eventually add that
example to the tree. I suppose that if you send the example in darcs
patch format (or publish your tree somewhere), along with the
necessary changes to examples.lisp and cl-opengl-examples.asd, that'd
be quite helpful and it'd speed things up.
