World: r3wp

At this point, I'm not sure it's worth documenting more. Perhaps 
2-3 years ago. 90% of work is currently directed toward VID for REBOL 
3 which is an entirely and far superior GUI system.

entirely = entirely different

could I use R3 for playing with graphics yet? Is the documentation 
public?

it has a few bugs, but you can play with it. docs are public.

I looked at RebGUI and had a play with the demos. Afraid RebGUI looks 
as if it would be even more complicated. I may as well start learning 
about R3 graphics as by the time I have learnt R3 I expect  R4 wll 
be in development.  :-)

R3 is still alpha software and the layout engine is going to be changed, 
since it's not laying out faces correctly many times, but the dialect 
is not likely to change. There are also only Carl's styles available 
in strong colors, and they are not so good looking.

but the underpinnings with GOBs, text and DRAW is fairly stable. 
it's fun to play with.

there is also glayout, which works very out of the box and is built 
over VID.  the api isn't document though.


you can look at the glayout-demo app on rebol.org so have an idea 
of all it can do.  it layout engine is very complete, and seems like 
the basis for how R3 was implemented... they use the same philosophy.


glayout handles ALL resizing automatically, and it even includes 
real scrollpanes, which react to content, as it changes (scrollbars 
resize automatically, for example)

there are just a few pointers to know if you want to create completely 
new styles, its not very complicated.

I am using it for my ssh-tool, which will be online within a few 
days (once I get my web server fully operational).

how do I get to the r3 console please?  I just get a dos type box 
with a >> prompt.

r3 lives within the OS console

so no interactive console any more?

or at least not for any code that splits across 2 lines

what do you mean by interactive?  its the same but instead of being 
a separate windows app, the console is directly within the dos prompt.

but it works complety differently?

no its pretty much the same.

Sadly: <The R3 alpha uses the default Windows console. This is a 
temporary situation until the new console has been created. >

>> print [
** Syntax error: missing "]" at "end-of-script"
** Near: (line 1) print [

I hadn't noticed the multi-line difficency !

So I just have to paste unformatted code only?

sunanda... for my part, I'd rather it stay there.  at least we have 
real stdio.

working in a telnet/ssh session for example, I can (in theory at 
least) use rebol remotely.

for my part, I'd rather use a rebol session as a remote shell, than 
bash.

I have to format the code in indented blocks to not lose track of 
what I am trying to do. Sorry to be so lame.

I do clipboard://

Ah that sounds like a plan

You don't even need a REBOL header anymore (I changed that).

The R3 documentation shows this example for view
view layout [
    h2 "The time is currently:"
    h3 form now
    button "Close" [unview]
]

But it does not work. Am I expecting too much from the documentation 
(sorry)    Could someone give me a graphics example that works please 
to start me off.

Sorry, I see the R3 docs are a work in progress.  I better back out 
of R3 graphics for now I think or I will get classed as a troll. 
sorry.

there are actually two sets of GUI documentation. The right one is 
located here: http://rebol.net/wiki/R3_GUI

Thanks Henrik, now I have some things that work to play with.. I 
also want to study Glayout...  AND Maxim's SSH-tool project sounds 
very interesting... Off to bed now, back to parsing tommrow I think.

I have found an example for R3 here  (about the only one I could 
spot so far)

http://rebol.net/wiki/Script_Writing_With_The_Visual_Interface_Dialect

It looks quite nice with rounded corners to the buttons too.

The example crashes when you try to exit so I suppose there is lots 
to do before this is ready for general use. I know how long developmnet 
cycles can take so I won't be holding my breath :-)    


I suspect the R2 functions built in will do more than enough for 
what I want & that I just need stick with one thing till I can understand 
it enough to know what it will do & what its limitations are. 


I showed my parsing project ot a work coleague & he suggested some 
additional data that it should colect, he was very impressed when 
I implimented his suggestion & tested it all in under 3 minutes.

I am reading about these mezzaines 3 times per day here and I still 
don't have any clue what they are... I googled but found nothing 
either.. .so what are mezzaines?

mezzanines are functions written in Rebol as opposed to C

In the Rebol console, look at the help for, for example, Foreach 
and Forall.


Under the description of Foreach, it says "FOREACH is a native value" 
- this means it is implemented directly in C in the interpreter. 
 FORALL says "FORALL is a function value" - it is written using other 
Rebol commands, and you can see the source of it using "source forall". 
 Mezzanine refers to this second type.

mezzanines vs native functions

does that mean something in English ?, because in French it does

hmm... same meaning

then all functions that I make when I program REBOL in REBOL are 
mezzanines? I thought there is something special about them

they just must have an abstract polymorphic usage

and staying small enough, i think

well, the exact definition is, all functions in Rebol which are not 
natives are mezzanines :)

But it''s Carl who makes the choice.

aha :) so it's more analog thing

Final definition:

All functions in Rebol that Carl don't want code as natives are called 
"mezzanines"

:))

Perhaps a new group "Bash Carl" should be more convenient

O don't want to be in that group :)

all functions written in rebol, *shipped with rebol* are mezzanines.
