World: r3wp

maybe the file you got from the link you posted is only core?

I built this one using the host kit

That's what I was alluding to ... earlier alpha builds had VIew built 
in, the latest does not. Oh well.

I was trying to make a build with r3-gui.r included, but when running 
the generation step of the build make-host-init.r outputs the error 
"Invalid tuple -- 2.147484e9x2.147484e9" when processing this file. 
Is there something wrong with this tuple?

the offending line in r3-gui is:
        max-size: 2.147484e9x2.147484e9

Ashley, you need to build your own R3 .. the downloadable ones are 
old

This is A105 that I built http://r3alpha.s3.amazonaws.com/r3.exe

did you include Henrik's view source?

Is there something wrong with this tuple?

 - sure, first of all, it is not a tuple, it is a pair, which your 
 version does not recognize

heh, of course it's not a tuple - my brain was trying to focus too 
hard on what was wrong with the pair - why wouldn't my bersion recognize 
it? Because make-host-init was done before the float pair support 
was added?

and it's confusing the definition with a tuple somehow?

No, it doesn't need Henrik's view source which is a moving target

it doesn't need it - I wanted to put it in

skimming... r3-gui.r3 requires A105. anything below will give a size-text 
error.

Anyway, it wasn't available when I built my r3.

See http://www.rebol.com/r3/changes.htmlfor binary downloads of 
hostkit builds

ie. Carl is now releasing compiled builds as well

A107 released

http://www.rebol.com/r3/changes.html

Carl, or anyone else who remembers - I don't recall what is holding 
things up in terms of making the source available so that people 
can try their hand at a client for R3 chat

Why do you need the Rebol source code to make a R3 chat?

just to see what the back end is doing - what API it exposes, etc. 
Of course you could find some of this out by sniffing, but why should 
this be needed. BTW, I'm talking about a client (say a web one) for 
the chat server that the built-in client connects to

I think Adrian means the source to the R3 chat server?

yes - I seem to remember Carl saying that he could make it available, 
but something still had to be done before he could do that

why ?

Claude, does it show the same, if you *don't* run the demo first?

I believe that the build that was posted didn't have the draw stuff 
in - on my own build, I get this error when I try the demo after 
loading your r3-gui script:

>> do %r3-gui.r3

** Script error: expected command! not font

** Where: size-text font-char-size? make make-text-style parse fontize

** Near: size-text gob

this makes sense because of the change to using command! in the dialect, 
I guess

Ah, you mean the R3 chat source code. I thought you need the R3 source 
code.

Adrian, the client source is readily available .. just not the server 
source

converting code to R3 isn't a piece of cake!!!  I mean real-world 
pieces of mature and optimized/tuned code... there are gotchas just 
about everywhere.

but I've now got slim working in R3  ;-)   am now working on converting 
liquid and other libs.

I'll eventually redesign slim so it uses modules though.

shoudn't resolve have a refinement called /bind  making it easier 
to rebind data to target context in a single pass?

is there a way to tell R3 to automatically show stack information 
when errors occur (and aren't trapped)?


python allows (on by default IIRC) this and its a MUCH more usefull 
error report.

for the same reason as for Rebol... many errors don't occur in user 
code, but in mezzanines, called by user code, sometimes several deep.


knowing why and where an error occurs is usually as usefull as what 
is the error  (and often, even more).

stack

yes, I can call it... but that means *I* have to call it.

http://www.rebol.com/r3/docs/functions/stack.html

which means I have to put exception handling in all functions... 
and even then, when an error occurs within a mezz... its not going 
to be reported there... so I won't have the stack based on its calling 
... so the end result isn't near as usefull.

trace/back ?

so for example, if an application halts due to an error... the stack 
is effectively empty, since its back to the command-line.  :-(

ex:  I added a voluntary 0 / 0 to generate an error.

liquid/add[3]/instigate() [
** Math error: attempt to divide by zero
** Where: / unless cleanup switch foreach either if insti
** Near: / 0 plug/dirty?: plug/valve/purify plug if all [
    plug/re...

>> stack 10
== none

whaooo  you don't even need me to feud anymore nice work guys continue 
that way ;)

this is a welcome change in R3   :-)

as opposed to in R2

== 49.54.55.49.49.54.56.48

to anyone holding back on using R3... with A107, I think we can really 
start to get serious in using R3

after a little bit more work on translating to R3... it seems to 
be much less work than it started out to be   :-D


I've got the basics of my dataflow canvas engine working in R3 (which 
is the basis for GLASS and many other tools of mine).


most of the time spent was in fiddling around with learning the changes 
in R3 view engine itself.   this is a 40kb lib running over another 
50kb lib... and its working as-is (once I removed references to the 
word 'FACE and system/words, mostly).

strange load behaviour.....   it doesn't load a file as rebol data... 
its only a string... I just had to do:

load load %datafile.r

just like if I was doing:

load read %datafile.r

What is in the file?

it seems to be related to the extension....  only a file with .r 
as extension is loaded as data... this insn't very cool.

the file name actually didn't have the .r in my script.

Indeed. LOADing should not be affected by the filename.
