World: r3wp

Only at the edges.

And, mainly at the human edge.

At the core, a CPU executes a sequence of instructions, not an object.

I guess I'd have to show you in actual code so you'd "see" it  ;-)

liquid is at the center of this, of course, but without objects, 
I coudn't easily hold state, process , cache and data together.

As far I know, Maxim don't use the nested gobs approach but reconstruct 
nested draw blocks instead.

liquid uses state to control processing.  each node is like a mini 
kernel only aware of itself.  by linking stuff together and with 
messaging, all the nodes cooperate.


right now, liquid is able to completely control a complete GUI forking 
of only the refresh of data which actually changes.  but i cannot 
implement some liquid's low-level code within extensions because 
they can't look up the nodes.

steeve, right, because in R2 there is other way to make a 100% AGG 
interface.

there is *no* other way

nested draw blocks may be slower in R3, but I see a benefit with 
Maxim's way. It allows easy composing and inheritance of transformations 
in the sub-blocks, like skewing, rotation, translation, scaling.

in R3 I could go far beyond, actually dumping some of liquid's processing 
directly in the native side of an extension.


in fact, I could use AGG or OpenGL directly without even using gobs 
or draw blocks since the interface is built by how you link things 
together and this linking and messaging will automatically fire-off 
AGG commands, without the need to go through an intermediate.

anyhow... object use is central to this, since its the most approachable 
way to group & bind things in context .

maybe you could simply convert your object into gobs ;-)

liquid is at a lower level than gobs (its not strictly gfx related) 
and I need object access for liquid (and other things).

off the topic, 

Gobs are not specifically related to graphics if they are not rendered 
(showed)

Gobs could be used to implement some efficient data structures, like 
linked list or tree.

As far I tested, dealing with structures of gobs is faster than with 
standard objets.

A really cool feature is that when a gob is append as a child to 
a gob, it's removed from its current parent automaticly.

Yes, true and useful too.

I need to find a group to discuss the PAIR changes happening. Suggestions 
anyone?

Core?

no !REBOL3

I guess. Kind of general group tho. Was hoping we had a graphics 
or datatypes group.

there's REBOL3 GUI

How to compile the sample ext-test.c using MinGW http://jira.rebolsource.net:8080/browse/REBOLKIT-5

Looks like it should be possible to call Java libraries from a C 
extension using the Java native interface ...

would be easier to use something like SWIG

http://www.swig.org/

Got an example of use with R3 extensions?

SWIG has REBOL support now? R2 or R3?

sure .. just use -r in the options :)

And then it magically reads your mind and chooses REBOL, rather than 
the R that it does support. We could use that ability in REBOL - 
it would allow us to implement half of the CureCode tickets we've 
had to dismiss :)

As you can see here .. Max took it upon himself to do something about 
swig R3B0L support http://www.rebol.net/cgi-bin/r3blog.r?view=0231

Ok, we can sign the 1 billion contract now

Has every group become the Humor group now? My grandma would say 
we are getting punchy :)

I guess we have to prove we're not a joke ...

Jocko, I was able to compile your tts example under visual studio 
express 2010 but with a lot of difficulties :(  
Size of the dll was 19.5 kbs vs your example which is 8.5kb

Maxim: Get and set of object fields has been added to the extension 
API in A101. So, great things can happen now?


But... before A101 is released I need a decent test for extensions, 
and Robert will be coordinating that project.

Graham, did not visual studio 2010 convert properly the visual 2008 
project file to visual studio 2010 ?

I had to do this http://jira.rebolsource.net:8080/browse/REBOLKIT-6

Maybe one would have fewer issues with using profession visual studio 
2010

@Carl, the chicken came first!  So, just give us the A101 download 
link

It's not done yet.

Anyone want to try this?


write %cimgtest.dll read http://www.compkarori.com/r3extend/cimgtest.dll
secure [ extension allow ]
import %cimgtest.dll
test

This loads up the C++ CImg Image Processing library and prints "hello 
world" in purple

Good to hear that the ban on directly importing extensions from URLs 
is still in effect. It's a good rule.

Eh?  Didn't try that ...

Shame shame ....

Now to see if I can get tetris up and running

It's good, really. It means that you can secure a sandbox and still 
allow extensions, just by prohibiting writing to disk.

Here's another test 
download  http://www.compkarori.com/r3extend/img.zip
unpack it
run the r3.exe

secure [ extension allow ]
import %3d.dll
test

and it shows a 3d figure you can rotate with the mouse

How to simulate argc, argv .. I guess we just read the frame

Except there's no way to call or declare commands with argc, argv 
style of arguments in REBOL.
