from here you can access rebelBB (forum built using parse) or the 
wiki with lots of documents

kib, you might also find this page interesting: http://www.rebolforces.com/

Some good articles in the REBOL/Zine there. There were written years 
ago, but still good, I guess.

Thanks for those links (I already know rebol-france). I just discovered 
there are a lot of books on Rebol (I've bought the last one in French):

Do you know good Rebol hosting plans ?

good question and hum apart the one you will set yourself i don't 
know

after that depends on how deep you want your rebol to be embeded 
to your website

if you want to use rebol like php you can use cheyenne!

shadwolf: from what I've read, it's just a cgi script....but free.fr 
does not support them!

cheyene! is a web server writed in rebol to execute rebolscripts 
but i don't know free hosters proposing it

ok, thanks. I'll have a look at it.

I use Cheyenne with my HTML dialect to host small dynamic pages that 
take a few minutes to write.

Henrik: and you're self hosting ?

on my laptop at the moment.

Henrik: so when your laptop is off, your site too ?!

yes :-)

I have no better solution right now. I plan slicehost, linode or 
similar later.

if i was president i would ban apach and impose cheyenne! :O

Henrik: where are your pages ?

http://rebol.hmkdesign.dk/files/r3/gui/

Henrik: you wrote the R3 gui demo ?

i like the gold progress bars henrik  ^^

sliders in 032 are nice too

toggle ar too big in my opinion a toggle is to be put in a list of 
parameters

I only skin R3. I did not write the demo. Skin is far from finished.

(the gold progress bars are long gone. :-))

kib, if you wanna see, what can be done with REBOL, take a look at 
Canvas RPaint (see group Canvas). It's an port of the old DPaint 
for the Amiga made in REBOL. More than 12'000 lines of REBOL source 
(600kb) or 176kb compressed.

Hi, can someone help ?

about what?

Janko: thanks. I'm starting and don't understand why this snippet 
does not work : http://clojurepastebin.appspot.com/1003

In fact, I don't even know if it's the right way to write a 2 arguments 
function.

Most REBOL programmers use FUNC, and not FUNCTION, because it's easier. 
Let me see, if I can rewrite your function with func...

Geomol: I just followed the book I bought, it tells me that func 
uses globals, and globals may not be the best no ?

hm, you can make locals with FUNC.

It doesn't work, because RETOUR isn't defined. You just declare it 
(as a block). You need to actually make the block.

quartile: func [
	liste	[block!]
	/local malong retour
][
  retour: clear []

  malong: length? liste

  either (modulo malong 2) [ insert retour (length? liste) ] [ print 
  "longueur impaire" ]
  return retour
]

That may not be, what you want. I haven't figured out yet, what you 
want the function to do. :-)

Geomol: thanks! so when you declare an object, it's not build ?

don't mind about that function purpose : it does nothing interesting 
at the moment

:-) Careful. We have to get the terms right, because they mean something, 
declare, object, etc.

Examples of words, that get declared (defined or known from now on) 
and also get build:

a: none
b: 42
c: make block! 16


If you specify words to be local to a function, they don't get declared 
(build). It just mean, that when you refer to those words, they will 
be local to the function.

Geomol: right, i'll try to take care of my vocabulary :)

so

my-func: func [
	var1 var2
	/local var3 var4
][
.....
]


In this, var1 and var2 are two arguments to the function. var3 and 
var4 are treated local to the function, but they're not created yet.

Thanks Geomol, that's clearer now. I had to go for lunch, I'll be 
back in a few mins. (I've got a lot of questions, I find my book 
not clear at all).

An example:


>> fibonacci: func [i /local n old-n older-n] [n: 1 old-n: 0 loop 
i [older-n: old-n old-n: n n: old-n + older-n print n]]
>> fibonacci 5
1
2
3
5
8

I said "careful" up there, becuse you also have objects in REBOL.

Another version, you might find useful (at least to see how to make 
the same thing in different ways, and with different number of variables):

fibonacci: func [
	i
	/local a b
][
	set [a b] [1 1]
	 loop i [
		print a
		set [a b] reduce [b a + b]
	]
]

nice!

I said my book wasn't clear because in presenting blocks, it uses 
the words "arrays", then "lists" and "series" inside : it's quiet 
confusing.

I guess, words like "arrays" and "lists" are common in other languages. 
In REBOL, you'll see the word "series" a lot.

A block is a series of elements (inside [ and ]).
