World: r3wp

this is good :-) are you doing something specifically inspired by 
a specific kind? eclipse? xcode? visual studio?

I'm making one that resembles XCode, but it seems to me that when 
I need to arrange files and build files, it's simpler for me to just 
build a small dialect and handle it all inside a text editor

perhaps we should move to an IDE group

Yes, indeed.

you go make one if it doesn't exist.

Now this is in the REBOL devider.

Done.

thanks

Hi ! what's about R3 and CGI ? Can we use the current alpha in CGI 
mode ?

I'm not 100% sure about CGI in general but there is no -c cli option.for 
2.99.4.  afaik the only options advertised as ready for prime-time 
are -q and one that controls quit/halt behaviour.  Expect someone 
more in the know to correct what I just said.  I'm not 100%.  (Or 
after a perusal, I may correct myself in a few minutes).

Just taking a first look at the r3 Alpha

In Rebol 2
>> x: 1
== 1
>> - x
== -1
>>

In Rebol 3
>> x: 1
== 1
>> - x
** script error: cannot use subtract on none! value

is this by design or bug ?

it's by design

So what is the best way to change the sign of a number   
x:: 0 - x   ?

negate X

Would then be cool if  "** script error: cannot use subtract on none! 
value" was "** script problem: cannot use subtract on 'none! value', 
you may have meant to use 'negative value'"

<Can we use the current alpha in CGI mode ?>

It does not work for me....A simple CGI that should just return a 
short HTML page, simple returns an empty string.

I tried to run the fledgling Rebol.org test suite against the public 
alpha to get a first impression of the impact of the changes in R3.


The first stumbling block is that RUnit (run.r) accesses system/error
  

I looked in DocBase but couldn't see any reference to the "new" System 
object. Any hints on where to find documentation on the changes to 
the system object?

The system object will be obsoleted soon, AFAIK. Unfortunately I 
have no details on what is replacing it.

I think it has something to do with modules, which are not yet done.

Thanks, Henrik. I'll wait to see what comes out later. There's still 
more work than I can handle left in building the Rebol.org test-suite 
so I won't be twiddling my thumbs.

A small status update for those interested: VID3 work is commencing. 
Gabriele is building a dialect to make it simpler to build VID3 styles, 
lots of discussions coming from that. The rest of the team are commenting 
this code.


Carl is still busy with Unicode. In fact there is so much to be changed 
due to Unicode, that we had a discussion yesterday seriously, whether 
R3 would still be called REBOL afterwards. The conclusion was that 
it was not a good idea to rename REBOL to something else. :-)

A couple of bugs reports have been made, but nothing crazy yet.

If anyone is interested, there is a task that needs to be done:


We want to list all functions in R3 vs. all functions in R2, so you 
can have a direct reference to compare each function between the 
two. This will help in listing those subtle changes that R3 has in 
functions and there will be many more subtle changes when unicode 
releases are done. This is only meant to be on a per-function basis 
and not for higher level ways to do things

I suggested thereby that we output the internal help of all functions 
in R2 and R3 in a two-column table with R2 to the left and R3 to 
the right. Similarly for all mezzanines, we would output the source 
code to each function in a separate two-column table of the same 
format.
When that is done, it needs to be formatted for DocBase.


If anyone is interested in doing that, just signal it in this group.

BTW: This should be a standard script that we can run again and again, 
so we can refresh the tables when a new release comes out.

Also asked this on the mailing list.

How does Unicode change Rebol so much? Not from the coding standpoint 
as far as Carl described in his blog...

any function or native that needs to work with strings or binary 
needs to be considered for change.

So there may be alot of R3 that needs to be recoded now? Stuff that 
we thought was complete?

everything is being reviewed. has been happening for more than a 
month.

I think the plan is to release a new alpha once the unicode changes 
are done so you can get to test it. We already have a Unicode version 
internally, but it contains only a few of the required changes. Carl 
reviewed the CHECKSUM and ENCLOAK functions yesterday and mentioned 
how CHECKSUM is now binary only. It won't work on strings directly 
anymore, because encoding issues would make it work incorrectly.

After unicode comes modules.

You might wanna know what I have been doing using REBOL 3 Alpha. 
Check it out. http://jerrylovesrebol.blogspot.com/search/label/REBOL

It's cool, Jerry! :)

Geomol, thanks. It looks cool, but the performance and the architecture 
are not good. I am rewriting it.

Jerry, nice view into your programming history and how you turned 
to Rebol.

Broke, thanks. It's the fate which brought us to REBOL. I just don't 
understand, why just us, a small bunch of people.

Many don't 'get it' yet.

People like to do things the way they've always done them.

Conservation of initial energy.

true ...

Is anyone able to point me to where to look for an error in some 
simple custom R3-VID-style? The following error message clearly doesn't 
cite my own code, some window handler code seems to try call FACE/FEEL/ON-MOVE 
on a FACE = NONE! oder FACE/FEEL = NONE! The error happens as soon 
as I hover the face in question:


** Script error: path face/feel/on-move is not valid for none! type

** Where: either handle handler while applier wake-up loop applier 
wait do-events catch if either if do begin do
** Near: either drag-gob [
    either drag-min [
        drag-gob/off...

that's inside VID3 alright, but what exactly happens, I don't know.

I can't remember if it is because some function inside your style 
isn't returning a face value or what it is.

Jerry; "why just us"  imho one of the bigger reasons is that we, 
the faithful, communicate in the dark.   There is a buzz, but no 
one hears it.  There is no comp.lang.rebol for people to "bump into" 
for instance.   reboltalk.com gets a few (or less) posts a day, but 
imagine how it would look if the Altme trafic counted.


Sunanda has helped with aga (and RT before) with the web exports, 
but the rebol.org data is "old news" and doesn't allow a surfer a 
chance to take part.


We get excited (a good thing) when we see a REBOL mention on a site. 
 I'd like it if say schemers got excited to hear rebols discuss Arc 
(that would be a better thing).


So the power the Altme (a wonderful comm system) has us in a position 
of "Hoist by his own Petard"

the power the Altme = the power of Altme

Thanks Henrik! Yes, I was assuming some NONE somewhere in my code 
instead of a face, too. Still not solved, though :-(

I've seen similar errors, but it's been a couple of months since 
I last touched VID3. It's a good idea to take a look at an existing 
style to see what's missing. I'm fairly sure that some code is missing 
in your style.

(hopefully this problem completely disappears when the new style 
dialect is done)

Christian: you haven't set gob/data for one of your gobs. don't worry, 
this will mostly be automatic in the next version... :) anyway, gob/data 
has to be set to the face the gob belongs to for each gob you have 
on display.

Thanks Gabriele! I've learned it the hard way, so the good thing 
is, that's something I will never forget again. :-)

drop-file.r show how get draggin from windows enviroment. Is possible 
 to initiate a Drag 'n Drop operation from REBOL3? (ie for to send 
an image to another application).
