World: r4wp

Have a look at these ones:
- http://static.red-lang.org/red-system-specs.html#section-1

- slides 7 to 13 in my SFD presentation: http://www.red-lang.org/2011/09/red-at-software-freedom-day-2011.html

The DSL link in the docs is going to the French Wikipedia. You may 
want to anglicise that

Read ! Very interesting.

Now I have understood.

Kaj: hehe, good one. :-)

URL fixed.

@Doc : Thanks for the try of the emulator - Now installing the Android 
update for my - almost 50 % left to do after 30 minutes - for an 
88 MB download - !!!  I will retest after everything is completed...

@Doc : Now I'm upgraded to Android version 3.2 Kernel is left unchanged 
to version 2.6.36.3 - Will try later for the tests - other more urgent 
taks are awaiting  for me now ...

No problem, I will test with 3.2 too.

Doc, Maybe it has been asked thousand of times. Which will be the 
differences in RED Lang compared to REBOL ?

Only 999 times :-)

Hehe :-) For the core language, from user perspective, it will be 
very similar. For the external libs (GUI mainly), Red will provide 
different options. For more detail, you can re-read all the slides 
from the two presentations I've made for Red.

@Doc : No better success even if running from NativeEXE.apk version 
0.5 and Android version 3.2 - will continue to read before being 
able to investigate myself what could be done - Please don't loose 
your time on this case for now - You have much better  to do ... 
even if it's annoying a bit. I don't despair but I really can't be 
useful to you for now... my understanding of the inner working of 
this stuff exceeds my current capabilities !

a "hello world!" written in and compiled by red/system running on 
a raspberry pi:

[pi-:-raspberrypi]:~$ ./hello-reds.arm 
hello from red/system!

([pi-:-raspberrypi]:~$ uname -a

Linux raspberrypi 3.1.9+ #90 Wed Apr 18 18:23:05 BST 2012 armv6l 
GNU/Linux)

Nice :-)

cool :-)

Does the provided hello.reds script work too?

hello.reds works as well, yes.

who's raspberrypi ?

I expect it's Andreas' RaspberryPi, as Doc tweeted, that his is still 
undelivered?

Mine, yes.

There is now also an English page on Wikipedia about Red:

http://en.wikipedia.org/wiki/Red_%28programming_language%29

Cool!

we can add red-lang.org and cheyenne-server.org links to the external 
references.

red-lang.org is there. Cheyenne doesn't have much to do with Red 
yet

However, Windows, OS X and Android are missing from the OS entries

we can copy/paste "about" section from http://www.red-lang.org/p/about.html
as well.

Be careful with that. The Red site is speaking in the future. Wikipedia 
will not regard that as encyclopedic information

I see. So we will put those information after Red is completed.

It would be interesting for RED to be a strict superset of REBOL...

It is interesting what does DocKimbel think about such possibility...

You're right: as a compiler, it can't be

Bas: great work, thank you!

Evgeniy: I am not sure if a strict superset of REBOL is doable in 
Red without introducing some important runtime overhead, making the 
compilation approach much less efficient, so less useful. I'll try 
to push it as far as possible and will stop when we loose too much 
performances.

Hello Doc - how are you doing, lately? Still busy with the non-red 
related contract? :-)

Unfortunately yes, but it should end in about ten days, so I could 
finally get back to the interesting stuff. I'm becoming an MQL4 language 
expert now, and I really don't like that (even if it can make me 
see some interesting niche opportunities for a Red dialect). ;-)

Well, as for dialects, I still can see PARSE as a secret weapon. 
Hopefully Red gets to R3 or Topaz level, as far as parsing goes. 
We could create some dialects for niches, I think ppl would see the 
advantage ...

It's possible to do something like [s: make c-string! 1000] in Red? 
So I would reserve 1000 bytes long c-string?

I tried declare but that leaves me with empty c-string!

I haven't found away to pre-allocate memory for a c-string! in Red/System 
except by initialising a string.

ah, that's unfortunate. thanks

Red/System has no memory manager. You need to use the allocate/free 
wrappers provided by the runtime (see %Red/red-system/runtime/libc.reds). 


Once Red's memory manager will be stable, we could easily add some 
simple functions to make it available from Red/System too, so you'll 
be able to either manually manage memory or rely on Red's memory 
manager (including being able to call the GC).

Ah, great! Thanks.

How can I get address of c-string! variable?

c-string! variables are memory pointers, so you're already manipulating 
the address. ;-)

yes, but if I want that adress for another purpose like copy-memory 
function?

Just pass the variable name.

I tried but ended with:

*** Compilation Error: argument type mismatch on calling: copy-memory
*** expected: [pointer! [byte!]], found: [c-string!]

You need to make a type casting: as byte-ptr! <variable>
