World: r3wp

Henrik, thanks for the vmware note, good to know - also the issue 
with rebol 2 on the newer macs, wasn't thinking about both sides 
of the problem.

It seems to work on macs that were upgraded from Tiger without doing 
a clean install or an archive and install. Some library is being 
carried over from the Tiger install, I think.

Ah, I remember the issue now.  That is a pain, it does work fine 
for me in Leopard.  If you need more help tracking down what is different 
let me know, don't mind poking around for you.  I have both intel 
and ppc macs that are still on tiger that might help as well.

well, I've tried digging out the version numbers for libraries used 
on both Leopard machines that work and Leopard machines that don't 
work and the version numbers are the same.

It's possible, although unlikely, that 10.5.2 would fix the issue, 
but I don't know.

I would imagine that REBOL isn't the only program that stopped working 
like this.

at least not on 10.5.2 beta

I know it's far away but what are the design-plans for compiling 
with the upcoming SDK3. 

Do we still compile/pack into one executable file, or one executable 
+ hostlib?

It is one !extrem! cool feature that compiled/packed rebol doesn't 
need additional files 
even own system lib's or other garbage/bloatware to run.

one file

the .dll is just for developers. when you download from rebol.com 
you get just rebol.exe like with r2.

good to know, thx gabriele

Could an Admin here please put this group in the REBOL divider?

I've been reading the R3 docs and I can't wait to start working on 
an IDE again.  Unfortunately I don't have enough time to really chase 
that again...  Yet!

ammon, do you have ideas for an IDE? I'm building an R2 IDE, but 
am a little stuck as to its usefulness.

Yes, I have LOTS of ideas for an IDE! 


A few months after joining the REBOL community (very soon after IOS 
was released) I actually started a funded IDE project for REBOL. 
 I spent quite a bit of time discussing these ideas with Carl who 
agreed to release it as THE REBOL IDE but unfortunately the funding 
died.  I've tried numerous times to renew the project all to no avail.

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.
