World: r3wp

missing object: look at the source of try-topaz.html. what you need 
is probably there.

I don't have string parsing in Topaz yet, but I wanted to illustrate 
how what Endo is asking in the Parse group would be much easier:

Topaz Interpreter - (C) 2011 Gabriele Santilli - MIT License
>> b: ["bla" 1 2 "bla"]
== ["bla" 1 2 "bla"]
>> parse b [collect any [keep number! | skip]]
== [1 2]

Looks simple. Cool!

Cool, I want collect/keep in R3 too :-)

>> parse b [collect any [keep number! | skip]]
== [1 2]


Very interesting. What would be returned if the parse rule was more 
complicated and "failed" (ie would have returned false in REBOL).

If it fails, it returns none.

PARSE works in a similar way to DO, in that it returns the last "result". 
I will document this in detail before a 1.0 release. There is a slide 
in my september presentation about PARSE vs. INTERPRET which explains 
why I went this route.

Thanks, Gabriele

Does it return the subject series at the position of the last result, 
or does it return the last recognized pattern as a value?

Brian, each "rule" has two effect: it advances the series, and returns 
a result. Most rules return the matched value, but not all. Examples:

>> parse [1] [number!]
== 1
>> parse [1 2 3] [number! number! number!]
== 3
>> parse [1 2 3] [some number!]
== 3
>> parse [1 2 3] [object [a: number! b: number! c: number!]]
== object none [
==     a: 1
==     b: 2
==     c: 3
== ]

>> parse [1 2 3] [object [a: number! b: object [c: number! d: number!]]]
== object none [
==     a: 1
==     b: object none [
==         c: 2
==         d: 3
==     ]
== ]

Seems a bit like a cross between a destructuring matcher and regex. 
Useful.

Hi, I am interested into building an maintaining documentation for 
those programming languages based on REBOL.
It would be nice to have a DOCBASE for them.
What I search is:
- Someone ABLE to SETUP the Linux and the Wiki Software
- Someone which would share with me the cost of hosting.
Do you like the idea ?

Note, the Topaz specific wiki is on github: https://github.com/giesse/Project-SnowBall/wiki

Gabriele, you might want to update the Getting Started page on github 
in relation to using Topaz with Windows. The situation is much improved 
now that there is an official Node installer (also includes npm).

so you don't need to mess around with Cygwin anymore

Thanks, I don't really use Windows so it's hard for me to keep up 
to date on that front. Peter already said he's going to update the 
wiki; if anyone else wants to help, I believe github allows a fork 
approach to the wiki as well, otherwise I can add you to the main 
wiki to edit it directly.

Also, you only really need to install node etc. if you want to work 
*on* Topaz, otherwise you can use any web browser to just *use* Topaz, 
like in the try-topaz.html example.

I wonder if it makes sense to allow REBOL to call try-topaz.html, 
although it would be calling JS code? Then you could mix Topaz with 
REBOL for tests, etc.

res: topaz [1 + 2]

a topaz function for REBOL, you mean?

yes, something like that

once I have the compiler, it would certainly be possible to target 
REBOL instead of JS. not sure if that is useful though. :-)

but, i guess you can use CALL to run node.js, or you can get node.js 
to listen to a tcp port and connect to it from REBOL, etc.

I was only thinking about whether it could be used to test topaz 
vs. rebol via one piece of code.

ok

henrik, do you mean something like? :

topaz: func [ block ][

 load read/custom http://server/try-topaz.htmlreduce ['POST  mold 
 block]
]


(where the post data above is replaced by whatever is required to 
properly fill in the form)

Maxim, certainly not, as there is no server side whatsoever to try-topaz.html

ok, I thought the discussion about using node.js was for this purpose... 
to have server and client side using the same language... sorry for 
the confusion.

Topaz runs in any JS interpreter; I use node.js because it's convenient. 
try-topaz.html uses the JS interpreter in your browser to run Topaz.

then it may be too much trouble. I was simply curious.

No arithmetic operators in topaz yet?

>> 37 * 11
*** Script error: Word has no value: *
*** Stack: * 11

Not implemented

I've updated the getting started wiki page at GitHub.

Please let me know if there are any errors in it.

Last comitt was 3 months ago?

I'm busy.

Added a couple commits to make Graham happy. :P

I need to check the Topaz G+ hangout :)

We need to do that again soon... I'm leaving for LA in about a week, 
then we have BIL2012 there, then I'll see if I can set up a hangout.
