World: r3wp

(just being silly about the foreigners stuff, but the ticket is serious)

Where's Jerry when you need him?

In a decade of REBOLing, Ive tried to use it exactly twice, and ended 
up having problems, so I created global words instead and forgot 
about it.

Guys, what are you coding with R3 currently ?

I've been mostly writing R3 itself. The projects I want to work on 
require capabilities that R2 don't have, and R3 didn't - until recently.

I've been trying to get R3 in shape to use for my projects, and it's 
been paying off recently (extensions, command!).

Actually, there is too much evolutions, i can't focus on a specific 
project

Haven't used R3 for anything serious yet.


but now that extensions are upon us, the OpenGL integration will 
allow me to use R3 for a *VERY* serious project.  still need Carl 
to fix the make/copy issue before I can convert most of my cool stuff 
over to R3 (like liquid and globs).

I hope extensions will be in the linux and mac ports shortly.

R2 still pays the bills and works very well for me.

OpenGL integration is a too big project for me, i lost my motivation 
after some days

Its working on my system  :-)


when A80 is out, depending on what he will have added to the API, 
I will try to port a simple OpenGL game to REBOL  :-)

well, i have some fun coding a proxy for R3 since some days, but 
I reach my limit attention

porting relavance to REBOL is also another big project of mine, probably 
will start in under a month  :-)

another one RDBMS

It's not Relational, is it?

ADBMS, sorry

Assoiative, relational... 

To my mind, there is no difference, it's just the query language 
which is different

*associative

At the end is always the same problem.
To have fast indexation algorithms

I don't code R3 things yet. Too many moving targets.

Re ALIAS -- it has several security and other issues.

Enabling it via SECURE is a good way of limiting the inadvertent 
damage it can do....And of drawing attention to its dangers for any 
casual dabbler.

The module rework has finally been submitted :)

Now it's time to backport it to R2/Forward, to the extent possible.

The set-block! datatype would make good sense with functions, that 
return more than one value. In Lua, a function returning 3 values 
can be defined as:

function f () return 1, 2, 3 end

and be called like:

a, b, c = f ()


Now a, b and c holds the values 1, 2 and 3. In REBOL we have to write:

set [a b c] f

It would maybe be nice to be able to write:

[a b c]: f

I find it easier to write set [a b c] than to notice the colon on 
the end of [a b c]: - but that may be just me.

Yes, the colon can be hard to notice. It's hard to say, if it will 
be easy to read such code.

The readability of REBOL is one of the deliberate design features 
that makes REBOL quick to program in.

I'm working with a long time REBOL programmer these days. We discuss 
the language now and then. One thing, we discuss, is how the minimalistic 
syntax can make REBOL hard to read. We can use parenthesis for arguments 
to functions, but we rarely do it. We could write:

insert (back (tail (series))) value

but a REBOL programmer would just write:

insert back tail series value


Even if we use parenthesis, REBOL requre different parenthesis notation 
than other languages. The above code in C would look like:

insert (back (tail (series)), value);

And C programmers often don't write the code this way with functions 
within function calls. They use to write:

void *pointer = tail (series);
pointer = back (pointer);
insert (pointer, value);

or something.

That is only because of line-oriented debuggers :)

This, I think, is one of the huge benefit of REBOL. To be able to 
combine words into sentences, that actually makes sense to read and 
understand. I don't know of any other language, that can do it this 
good.

steve, belive me... there is ABSOLUTELY nothing in common between 
relavance and all the db you are used to .  absolutely nothing.

kaj, no its its a system of associated nodes.

its like programming cells directly. no rows, no columns, no tables.

Steve, I'm with you.  I don't see anything special about associative 
model.

I can only say that's cause you haven't used it.

Maxim, I need that relevance think, was impressed by Ron presentation 
at DevCon France! My knowledge is less organized since I stopped 
using vanilla. I need to write a new wiki engine, have tried trees, 
nested set, adjacency, file system based, none satisfy me.

guys, what is Relavance price level? Is it suitable for normal guy 
to play with? Or just for big and specific projects?

Max - re your request towards RXI - I thought that image datatype 
was already accessible via the API?

think -> thing

When I perform get * in R3 Chat, I can see some files are not probably 
updated locally? I can see:


--- Note: work file changes would be lost, skipped: work/r3/mezzanines/mezz-intrinsics.r

--- Note: work file changes would be lost, skipped: work/r3/mezzanines/mezz-load.r


Does it mean those files were not updated on my machine? I did no 
changes locally.

That means that you already had versions of those files in your work 
dir, and that get * didn't overwrite them. If you haven't made local 
changes to any files in that directory, do a purge-dir, then get 
*.

Is this a new error?

REBOL[]
load-gui
stylize [my-button: button [actors: [on-click: [probe face]]]]
view [my-button]

If the button is clicked:
** Script error: cannot access start in path drag/start:

** Where: if do-events do-events do-events either applier wake-up 
loop applier wait do-events if view
** Near: if object? event [
	drag: event
	drag/start: where

Nicolas, please check whether the return value from ON-CLICK can 
be a face. After clicking, it's possible to return a drag object 
and if a face object is returned, it might fail.

Just quickly reading about PHP's "return" function. It's interesting; 
it does not have to be in a function. It can return the evaluation 
of a script to the calling context.

Seems like a good idea to me. Maybe Rebol should incorporate this 
idea?

quit/return?

Does quit already do that?

nope it apparently doesn't.

well, it doesn't write anything in the console. maybe I'm doing it 
wrong.
