World: r3wp

The problem is that most of the code written in R3 has been written 
by people who have a good idea of the internals, who know what is 
optimal and what is not. This means that the code tends to more heavily 
represent good code techniques and practices - thus, those code patterns 
are more thoroughly tested and stable. What hasn't been as tested 
as much is bad or erroneous code: Some of that can still crash R3 
at this point.


Fortunately, new users have been joining the fray, and many of them 
are not aware of the internals or best practices. Or in Ladislav's 
case, exhaustively thorough in their testing coverage. Because of 
this R3 is much more stable than it was a month ago :)

If you search curecode.org for [gc] or [garbage collection[ there 
are very few bug reports.

Maybe it is time for someone to step up and try some serious stress 
tests.

hehehe  I think I`m going to give A56 a real run for its money  :-)

Go for it, Maxim!

I'm going to try to port liquid to R3 tonight.... just for fun.

I'll be using modules if possible.   an earlier version of R3 just 
crashed when trying to allocate a single node... we'll see.

is there a page which explains various optimisations one can do to 
R2 code to allow it to take advantage of newer and faster functions 
in R3?

Maxim, try to look through the cookbooks section in the wiki at http://rebol.net/wiki/Cookbooks

There are a few things. Not much yet.

I tried porting one small script (not even an application) earlier 
today.
Good news -- it worked in most cases.

Bad news -- some of the sanity validations failed because the nature 
of strings have changed.


Lots of R3 is native where R2 was mezz......That often speeds things 
up.

I also need to get myself an account for the R3 chat.

Maxim, so many things to do. Can your super brain handle it? :-)

I've just finished helping the plumber install a new submersible 
pump in my 50 meter deep well, changed all the electricals too... 
I didn't have water for the last 4 days... 


now I can give myself a rare treat.  taking the rest of the day off 
today, so I can do my things.... and that includes one "fun" project... 
usually a short project that I've been putting off of a long time... 
today its liquid/R3  :-)

my brain isn't the problem... I only have two hands... sometimes 
I'd like to be dr octopus  ;-)

WOW   Rebol 3 is   #1  that's THE VERY FIRST LINK if you search for 

R3 alpha

It would be cool if it was the first that was returned if typing 
in "r3". :-)

well SAP is going to be a big one to topple for that bragging right 
 ;-)

I think Carl should post that in his next Carl blog  :-)   being 
first with something as generic as R3 Alpha is no small feat....

I'll poke him with that when I get to enabling my R3 chat later on.

Sunanda, your "memory exhaustion" ticket (bug#920) was not a GC bug, 
in fact not a bug at all. Look at the comment for details :)

You are quick with the bug analysis!


Not entirely sure why you consider it not a bug. Recast this way, 
it looks a horrible problem....
   for n 1 10 1 [print n a: mold system]
....It gets slower and slower and then dies.

...And the I may need a new session as:
  b: mold system
now does not have enough memory.

devbase is a strange space.  its like: "altme in the twilight zone" 
 even the white letters on black of the dos shell  bg re-inforce 
this  ;-)

I've noticed that devbase has the same problem as altme at recognising 
the daylight saving time... I have a one hour offset in time postings.

is that a known issue?

also the "g" command of devbase doesn't seem to work when #xxxx is 
in messages, but it works for curecode and html.

yes, it's a very known issue

I suppose 'g for message numbers could be added.

hehe... you posted just after I reported it directly on devbase... 
like seconds appart  :-)

I actually like devbase.  the direct number navigation is quite possible. 
 I can just type 14   and go to R3 section directly wherever I am... 
that is very cool.

possible = powerfull...

are any plugin docs available yet?

no, not yet

try

f "chat.r"

to get the post where you can get the source for chat.r

cool.

what rank must I be to create headings?

there is a list in devbase help in the wiki

aaah ok... will look it up

If you feel like adding a feature, go ahead, and post it to curecode. 
Carl probably prefers 1-2 line fixes, though.

ok.

could someone either raise my rank so I can add a lib within Community/Libraries 
or add a heading called liquid there.  I'd post my R3 related comments 
for liquid there... I think Carl would like some feedback on my efforts/problems 
porting such an advanced tool into R3.  when it will work, I'll also 
be posting comparative benchmarks.

Sunanda, the reason it's not a bug is because for every iteration, 
'a is set to mold system, and mold system includes the previous value 
of 'a from the previous iteration, as a string. So that means that 
every iteration is the length of the rest of the system, plus the 
length of the previous 'a times the number of visible references 
to it. Since there are 4 visible references to the collection of 
global words, this means that the growth is exponential, and of a 
larger exponent than R2 (which has only one visible reference to 
the global words, so it just doubles).


The way to prevent the exponential growth is to assign none to 'a, 
or unset 'a, before you mold the system again.

The 4 visible references to the global words should be cut down to 
1 or 2 once the rest of the module system is done. The other 2 will 
refer to separate contexts than the current "global" context.

I've officially just created a new file on my system.... its called: 
   liquid.r3  
let the fun begin  ;-)

first step, convert vprint to r3

#4515: Community/Libraries/Liquid

thanks :-)

has anyone been able to properly link r3 in windows file extensions?

Raised your rank.

I do everything and its not in the extensions list, but strangely, 
it is working, since clicking on a liquid.r3 loads it properly.


what is even stranger is that I scanned the registry and its not 
there either!

Associating a file extension is easy enough, but for now it is better 
to make shortcuts or batch wrappers instead. R3 is alpha :(

but what I mean is that someting in the r3.exe isn't letting my XP 
properly associate it... is this to be expected?
