World: r4wp

Is there a document anywhere that outlines the differences between 
R2 and R3 for those porting/writing apps now?  I'm thinking that 
those of us still using R2 should try and stick to something that 
will be compatible with R3.

The email of Carl is  [open-:-rebol-:-com]

This is a public group, MaxV! I assume that your action will force 
Carl to change his address and not give it to you...

Hey! Carl published the email on his blog!

Were you serious?

I do not know, but Carl was quite shy of publishing is mail address

Well, it isn't a personal email, is the email of the opensource rebol 
that he published, so he can ignore that email adress as he wish...

Which is what we ceratainly do not want. Please use some reason before 
publishing that may be perceived as private especially if it is not 
your private data.

Regardless if email addresses are munged in the rebol.org archives, 
don't post real email addresses in a web-public group unless you 
are attempting to test spam filters.

I agree with everyone, but the given address by MaxV is a *very* 
public mail address, so its not that big a deal IMHO.

Just good policy :)

As a matter of practice I generally share contact information for 
other people ONLY through individual private channels and NEVER on 
email.  Just a thought.

Has anyone had any contact with Steven Solie about the Amiga R3 build? 
 I see from his site http://solie.ca/that in 2010/11/23 he had R3-GUI 
up and running.

AFAIK, that's the only other platform where view was ported to so 
far

This looks like a question best suited for BrianH:


http://stackoverflow.com/questions/14420942/how-are-words-bound-within-a-rebol-module

Answered. Someone might want to adapt that answer for use in the 
docs.

Since he didn't ask about exporting and the 'private option, I didn't 
mention such issues.

I guess that since I never had a stack overflow account before, my 
previous answers don't count towards my stats.

I believe you can email the stackoverflow admins, Brian, and they 
can transfer stats to your new account.

I have no idea whether my old answers has associated email addresses. 
I suppose it doesn't matter.

What old answers if you don't have a SO account before?

For completeness I've asked the question about exporting and private

SO didn't previously require you to create an account or even provide 
an email address to answer questions. Since I didn't care about SO, 
I didn't bother to make an account. Now they require an email address, 
and use that email address to determine who you are. Creating an 
account is almost an extra, just a way to give you a nickname and 
profile info.

You need a reputation of at least 20 to use the SO chat system ... 
and with ticks, you're already there.

with 2 ticks

BTW, we are encouraging the use of SO as a help resource for those 
who won't or can't use Altme

Yeah, I found that annoying, but I suppose it makes sense.

Do you want me to edit my answer to include the exporting stuff? 
I can't really do it in a comment since it would be in the same scale 
as the original answer.

Edit the answer would be better

Or ask a separate question.

Also, SO has an API so we can potentially grab all the Rebol tagged 
questions and also host them on rebol.org if we need to.  It's not 
stuck in the SO system

Too late, Andreas, I'm already editing the answer. It makes it easier 
to keep context this way.

Done.

Thanks Brian, good answer!

So, should schemes be isolated?

I've never needed to isolate something, so in general no. Most stuff 
should generally be regular modules or scripts. The rest are special 
cases.

I can imagine that if you want to have a module somehow negitiate 
some passwords and don't want them to leak, or some other security 
issue, you might want to write the module to be isolated. Also, if 
Maxim wanted to port slim to R3, or someone wanted to port Qtask 
(I forgot what it's called now, sorry) or some other code written 
for Gabriele's PowerMezz modules to R3, they might want to use named, 
private isolated modules.

One interesting use of isolated modules is to use IMPORT/no-share 
to force a module to load isolated even if it wasn't written for 
that. This is a way to use modules that are too messily written, 
that make too many unnecessary changes, and try to limit the mess 
a bit.

negitiate -> negotiate

Was there ever a mysql driver for R3? I saw some examples in the 
"import" docs but the link is not working.

There's an ODBC driver for R3, at least on Windows. It emulated R2-like 
port behavior. Can that be used to access mysql?

According to the mysql ref, yes. Thanks for the tip.

However, on linux is easy to ovverride any problem using "call", 
in the end I prefer this way.

Id depends, how fast is CALL, but especially on Linux, there should 
be very little overhead. E.g. I found out, that PHP, for Unicode 
conversions, just calls iconv. If you don't call the function in 
loop, I would go the CALL way, with tiny wrapper parsing results 
back. But - CALL on R3 misses /output and /wait ...

We need some bounty to bring R3 CALL on par with R2 :-)

Maybe we could see what ist stopping Krzysztof from moving on this 
issue (which he mentioned he could work on). Possibly if some of 
the gurus would help him out with some Rebol pointers he could do 
it.

https://github.com/rebol/r3/issues/5

I contacted Krzysztof with this idea in mind.

wait  value  /all

Waits for a duration, port, or both.

Arguments:

value [number! time! port! block! none!] 


Could wait be enhanced to wait for a particular value like unless?

wait [ port zero? word! ]

You mean waiting for a condition, rather than for a port, time or 
duration?
